8 6. INSTALLATION OF THE UNIT 6.. Selecting an installation location The unit is to be placed in an indoor location that meets the following requirements: General WARNING Make sure to provide for adequate measures in order to prevent that the indoor unit should be used as a shelter by small animals. Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around the unit clean. Installation shall be done by a licensed technician, the choice of materials and installations shall comply with local and national regulations. The equipment is not intended for use in a potentially explosive environment. There is no danger of fire due to leakage of inflammable gas. If the sound is measured under actual installation conditions, the measured value will be higher than the sound pressure level mentioned in the "Unit specifications" on page 7 due to environmental noise and sound reflections. Choose the installation location carefully and do not install in a sound sensitive environment (e.g. living room, bedroom,...). Be sure that sufficient precautions are taken, in accordance with relevant local and national regulations, in case of refrigerant leakage. Location requirements The installation location is frost-free and indoors. Take care that in the event of a water leak, water can not cause any damage to the installation space and surroundings. The foundation must be strong enough to support the weight of both models. The floor is flat to prevent vibrations and noise generation and to have sufficient stability especially when the optional domestic hot water tank is mounted on top of the unit. Volume of installation location During operation the heat pump module increases the domestic water temperature by using the indoor stored heat. Typical installation location for this product is a garage, cellar, technical room, etc. To have an optimum unit operation and to prevent a too big temperature drop in the installation location, take the following requirements for the installation location into account: Minimum volume of the installation room The heatpump operation stops whenever the indoor ambient temperature becomes lower than C (this can be adapted by field setting [7-04]). After that, the electric heater in the domestic hot water tank module will continue to heat up the domestic hot water. This is a unit safety that prevents the installation room to cool down further (preventing that e.g. water piping in the installation room gets damaged) and guarantees a sufficient comfort level in the form of sufficient amount of domestic hot water. To prevent this safety to occur frequently and to assure the use of the electric heater as little as possible, the room size must have a minimum volume (see figure below). All depends on the outdoor temperature, the temperature setpoint of the adjacent heated room and the insulation properties of the walls. The volumes in the figure are valid for an outdoor temperature of 0 C and a temperature setpoint of the adjacent heated room of 6 C. With this room volume, the heatpump can heat up 60 liters domestic hot water from 0 C to 60 C. Garage included in house One wall and ceiling of garage are in contact with heated area Minimum required 60 m volume Square footprint 5 m Height.5 m Garage included in house Two walls and ceiling of garage are in contact with heated area Minimum required 50 m volume Square footprint 0 m Height.5 m When the installation room size does not match the minimum requirement volume or if the walls between the installation room and adjacent heated room have better insulation properties than a single brick wall, additional heat sources must be considered. Examples of heat sources: - if installed in a basement the ground surrounding the basement will heat up the installation room temperature - if installed in a garage, the heat of the cars engine - natural ventilation via e.g. doors leading to the adjacent heated rooms - ventilation connection to a heated room - other: washing machine, dryer 6

9 Humidity of the adjacent heated rooms The room where the unit is installed will cool down. Depending on the relative humidity temperature in the adjacent room and the insulation property of the common walls, condensation could occur on the wall. Installing near a wall or obstacle When the unit is installed as mentioned in the figure below, the performance and operation of the unit will be optimum. C 50 B 50 A B A B E.g. kitchen E.g. garage A 400 A 400 If the relative humidity in the adjacent heated room is often higher than 60% (e.g. bathroom) during the heating season (when outdoor ambient temperature is lower than 5 C) condensation could occur on the common walls. Relative humidity levels of a living room normally do not exceed this 60%. If this should be the case consider to limit the cool down of the installation room by considering additional heat sources (see above remarks). Air blowing out Depending on the operating conditions and the installation condition, the cold air blown out at the back of the unit can cause condensation or heat losses to surroundings. In this case consider to locally insulate the wall on the unit side, or install the heat pump module with the cold air blow out to an (e.g.) outside wall. A B C D A B C D E.g. kitchen E.g. garage Insulation Cold air blow out from heat pump module A B C C 50 A 400 B 500 Space required for switch box removal Space required for air intake Space required for air blow out to the left Where a wall or other obstacle is not according to the figure mentioned in "Installing near a wall or obstacle", follow the installation guidelines below. If the unit cannot be installed according to the figure mentioned in "Installing near a wall or obstacle", consider to use flexible piping between the unit and the customer water circuit. This could facilitate possible service jobs where access to one of the sides is required. Example: when water piping is situated in the blow out zone of the unit depending on operating conditions and the water temperature inside the piping this piping can condens. In this case consider to insulate the water piping. Depending on the operating conditions and the installation condition the cold air blown out at the back of the unit can cause heatlosses and even freezing up temperatures to e.g. non insulated water piping located in this cold area! In this case consider to insulate the water piping. Required space around the unit The space around the unit is adequate for servicing B 50 C 50 A 400 A 400 A B C Space required for switch box removal Left installation Right installation 7

10 Preferred installation locations Garage or cellar with a heat producing source (for example a washing machine or drier, a freezer, a hot boiler for space heating or an other heat emitting source). Cellar that will release heat from the floor. Room with good insulation towards outside. Room that needs to be dehumified. Do nots Do not install the unit in places often used as workplace. In case of construction works (e.g. grinding works) where a lot of dust is created, the unit must be shut down and covered. Do not install the unit in places with high humidity (e.g. bathroom) (maximum humidity (RH)=85%). Do not install the unit where there is a mist of mineral oil, oil spray or vapour for example a kitchen. Plastic parts may deteriorate and cause them to fall out or water to leak. Do not install the unit where corrosive gas, such as sulphurous acid gas is produced. Corrosion of copper pipes or soldered parts may cause the refrigerant to leak. Do not install the unit where flammable gases may leak, where carbon fiber or ignitable dust is suspended in the air or where volatile flammables, such as thinner or gasoline are handled. Such gases may cause of fire. Do not install the unit where acidic or alkaline vapour is present. Do not install the unit in places where water leaking from the unit can cause damage to the location (e.g. in case of a blocked drain pipe). Do not install the unit near a bedroom and the like, so that the operation noise will cause no trouble. Do not place any objects or equipment on top of the unit (top plate). Do not climb, sit or stand on top of the unit. Do no install in a room without any means of heating inside that is not connected to an other room with a heating source (for example a garden house). 6.. Field piping Provisions at the cold water inlet of the domestic hot water tank - To avoid back siphonage it is advised to install a non return valve on the cold water inlet in accordance with local and national regulations. - It is advised to install a pressure reducing valve on the cold water inlet in accordance with local and national regulations. - Provide a connection for a pressure relief valve on the cold water inlet. - Install an expansion vessel on the cold water inlet in accordance with local and national regulations. - Install a drain device on the cold water connection on the domestic hot water tank. WARNING Do not install any valves between the domestic hot water tank module and the pressure relief valve/expansion vessel. It is advised to provide a shut off valve before and after the unit. This will facilitate maintenance on the domestic hot water circuit. It is recommended to install a shut off valve on the cold water inlet. Close this shut off valve during periods of abscense to avoid damage to the surroundings in case water should leak.

Specifically take care that: - Chloride content maximum 50 mg/l - Sulphate content maximum 50 mg/l - Combination of both maximum 00 mg/l The unit must not be used with water from a private supply. In known hard water regions, precautions should be taken to prevent lime scale formation in hot water. For safety reasons, it is not allowed to add any kind of glycol to the water circuit. To avoid stagnation of water, it is important that the storage capacity of the domestic hot water tank meets the daily consumption of domestic hot water. In cases where during longer periods of time there is no consumption of hot water, the equipment must be flushed with fresh water before usage. The disinfection function provided on the equipment is specified in the operation manual of the unit. Checking the water circuit The units are equipped with a water inlet and water outlet for connection to a water circuit. This circuit must be provided by a licensed technician and must comply with all relevant European and national regulations. Before continuing the installation of the unit, check the following points: The maximum allowed unit water pressure is 0 bar. The maximum water temperature at the unit outlet is 75 C. Take care that the components installed in the field piping can withstand this water temperature. DANGER The maximum water temperature to the unit must be limited to 55 C. Drain taps must be provided at all low points of the system to permit complete drainage of the circuit during maintenance. One drain valve in the indoor unit is provided to drain the water from the indoor unit water system. Only perform this draining when all the water of the domestic hot water tank is already drained. Take care that the components installed in the field piping can withstand the water pressure and temperature. Always use materials which are compatible with the water used in the domestic water circuit. In the unit water circuit copper, stainless steel and brass is used. WARNING Never use Zn coated parts in the water circuit. Excessive corrosion of these parts may occur as copper piping is used in the unitís internal water circuit. 0

13 Connect the domestic hot water tank module to the heat pump module Refer to the unpacking instruction sheet. If the domestic hot water tank module is put next to the unit, installing of the EKFMHMSAA kit is necessary. Refer to the manual of that kit. Make sure to check if the speed setting of the pump is set in position III if the domestic hot water tank module is mounted on top of the heat pump module. Connecting the water circuit Water connections must be made. The location of the water inlet connection and the water outlet connection on the unit is shown in the chapter 5.. "Overview of the domestic hot water tank module" on page 4. WARNING Be careful not to deform the unit piping by using excessive force when connecting the piping. Deformation of the piping can cause the unit to malfunction. Use two wrenches as shown in the figure. Connect the drain pan During operation and depending on operation conditions the heat pump module collects condens water in the drain pan at the bottom of the unit. Make sure to provide a proper drain connection to this drain pan. CAUTION: Requirements to drain piping The drain piping must be positioned away from any electrical components. The drainpipe must terminate in a safe, visible position without forming any risk to persons in the vicinity. All drain pipe work must be installed in a continuously downward direction and in a frost-free environment. It must be left open to the atmosphere. 7.. Precautions when connecting field piping and regarding insulation The complete water circuit, inclusive all piping, must be insulated to reduce loss of heat. If the indoor ambient temperature is higher than 0 C and the humidity is higher than RH 80% then the thickness of the insulation materials should be at least 0 mm in order to avoid condensation on the surface of the insulation. If air, moisture or dust gets in the water circuit, problems may occur. Therefore, always take into account the following when connecting the water circuit: Use clean pipes only. Hold the pipe end downwards when removing burrs. Cover the pipe end when inserting it through a wall so that no dust and dirt enter. Use a good thread sealant for the sealing of the connections. When using non-brass metallic piping, make sure to insulate both materials from each other to prevent galvanic corrosion. Because brass is a soft material, use appropriate tooling for connecting the water circuit. Inappropriate tooling will cause damage to the pipes. Connect the pressure relief valve (field supply) and drain In accordance with relevant local and national regulations, a field supplied pressure relief valve with an opening pressure of maximum 0 bar must be connected to the pressure relief valve connection. Make sure to provide a proper drain for the field supplied pressure relief valve to avoid any water coming into contact with electrical parts. 8. CHARGING WATER 8..

In case there is a water leakage close the water inlet and water outlet shut-off valves and call your local dealer. 9 Power supply voltage Check the power supply voltage on the local supply panel. The voltage must correspond to the voltage on the identification label of the unit. Once all checks are fulfilled, the unit must be closed, only then can the unit be powered up. When the power supply to the indoor unit is turned on, "88" is displayed on the remote controller during its initialization, which might take up to 0 seconds. During this process the remote controller can not be operated. 0.. Field settings The unit should be configured by the installer to match the user demand. Thereto, a number of so called field settings are available. These field settings are accessible and programmable through the user interface on the unit. Each field setting is assigned a -digit number or code, for example [-0], which is indicated on the user interface display. The first digit [] indicates the 'first code' or field setting group. The second and third digit [0] together indicate the 'second code'. A list of all field settings and default values is given in the "Field settings table" on page. In this list we provided for columns to register the date and value of altered field settings at variance with the default value. A detailed description of each field setting is given under "Detailed description" on page 9. NOTICE Field setting [] depends on the relevant local and national regulations. Before changing these settings, the new values shall be confirmed by the installer and/or shall be according to the local and national regulations. Different domestic hot water tank operation modes To understand the field setting possibilities explained in the following chapters, understand that different domestic hot water tank operation modes are possible. Powerfull operation If the P button is pressed, the heat pump module heats up the domestic hot water tank as fast as possible to a predefined setpoint. This means that the inverter compressor frequency will be higher then in normal operation mode and that sound level and power consumption can be higher. This mode might be usefull when exceptional high hot water consumption depletes all the available domestic hot water and hot water is required. Depending on settings, simultaneous heat pump operation and booster heater operation can occur. The unit increases the domestic hot water temperature by using the indoor stored heat. The powerful mode might not function properly when the room ambient temperature is too low. Disinfection operation This mode will disinfect the domestic hot water tank by periodically heating the domestic water to a high temperature. This can be required for e.g. legionella prevention. This mode is enabled by default. Refer to the chapter "Detailed description" on page 9 for a detailed description how to set one or more field settings. - [0-0] Set point: Disinfection water temperature to be reached (see figure "[] Disinfection operation" on page 9). - [-00] Operation interval: day of the week at which the domestic water should be heated. - [-0] Status: defines whether the disinfection function is turned ON () or OFF (0). - [-0] Start time: time at which the disinfection operation is started. - [-04] Duration: time period defining how long the disinfection set point temperature should be maintained. Even when the unit is in OFF mode, disinfection operation can work (depending on field setting [-0]). Reheat operation This mode will prevent the domestic hot water from cooling down lower than a certain temperature. When enabled the unit will heat up the domestic hot water tank when the reheat minimum value is reached. This heating will continue until the reheat maximum temperature is reached. This means that the unit can heat up continuously and e.g. not limited to night time operation. This reheat operation is only valid when schedule timer operation is enabled and not active. Automatic operation This operation mode contains a learning function to predict the daily hot water consumption. It will calculate and predict the optimum tank temperature setpoint based on the user tapping history. Enabling this operation mode will keep the tank temperature as low as possible but to a temperature which guarantees a high comfort level. The advantage of a low tank temperature setpoint are : - Reduced heatlosses - Better unit performance, the lower the tank temperature the better the heat up coefficient of performance (COP). - Lower electric power consumption Refer to the operation manual for a detailed description. 7

The algorithm calculates for each day of the week an optimum domestic hot water tank temperature set point. To calculate this temperature setpoint, the learning function monitors per 4 hours the domestic water heating demand and based on this demand calculates the optimum set point for that specific day of the week. This field setting contains the starting time for the 4 hours monitoring period. This field setting must be set preferably after the main heating up of the domestic water of the day has finished. For example: If in schedule timer operation mode the schedule timer was set from h until 6 h, the renewal time should be set at 6 h. [-0] Minimum automatic temperature set point If required the minimum temperature set point for the automatic set point calculation can be adjusted. If, for example, considerable heatlosses are expected on the field piping between the hot water tap and the domestic hot water heat pump, this temperature set point can be usefull. [-0] Maximum automatic temperature set point The maximum temperature that the automatic set point can reach. However, if this value is set on a temperature higher than 60 C, that maximum temperature will only be reached when field setting [-0] is set to (ON). If the setting of [-0] is 0, the maximum temperature will be 60 C (only heating up by heat pump) ignoring higher set temperatures. [] Disinfection operation The disinfection function disinfects the domestic hot water tank by periodically heating the domestic hot water to a specific temperature. NOTICE The disinfection function field settings must be configured by the installer according to local and national regulations. [-00] Operation interval: day of the week at which the domestic water should be heated. [-0] Status: defines whether the disinfection function is turned ON() or OFF(0) [-0] Start time: time at which the disinfection operation is started. [-0] Status: defines whether the disinfection function is turned ON() or OFF(0) during standby operation. If for example, during holiday the customer puts the unit in stand-by mode by pressing the Y button but still wants the disinfection mode to be active, the setting of [-0] must be ON(). [-04] Interval: time period defining how long the disinfection temperature set point should be maintained. [] Miscellaneous [-00] Auto restart When power returns after a power supply failure, the auto restart function reapplies the user interface settings at the time of the power supply failure. It is therefore recommended to leave the auto restart function enabled. If auto restart is disabled after a power supply failure, the system will restart in OFF-mode. Press the v button to start heating up the water again. Note that with the function disabled the schedule timer will not be activated when power returns to the unit after a power supply failure. Press the pr button to enable the schedule timer again. If the benefit kwh rate power supply is of the type that power supply is interrupted, then always allow the auto restart function. [-0] User permission level The remote controller can be programmed to make certain buttons and functions unavailable for the user. There are permission levels defined. The following table shows which functions are accessable with permission level and with permission level. Domestic water heating operation ON/OFF Permission level level Operable Operable Powerful operation Operable Not available Setting the domestic hot water Operable Operable temperature Quiet mode ON/OFF Operable Not available Auto adaptive set point operation Operable Not available ON/OFF Setting the clock Not available Not available Programming the schedule timer Not available Not available Schedule timer operation ON/OFF Operable Not available Field settings Not available Not available Error code display Not available Not available Displaying actual temperatures and Not available Not available water flow Changing unit of temperature Operable Operable ( C/ F) Changing user permession level Operable Operable By default no level is defined so all buttons and functions are operable. The actual permission level is determined by field setting. For permission level, set field setting [-0] to, for permission level, set field setting [-0] to. Once the field setting is set, the chosen permission level is not yet active. Enabling the selected permission level is done by simultaneously pressing buttons pi and pj immediately followed by simultaneously pressing buttons s and P, and keeping all 4 buttons pressed for at least 5 seconds. Note that no indication on the remote controller is given. After the procedure the blocked buttons will not be available anymore. Deactivating the selected permission level is done on the same way. 9

22 [-0] Status: defines whether temperatures above 60 C can be selected () or not (0). The maximum domestic hot water tank temperature by heat pump operation is limited to 60 C. A higher temperature set point is only possible by electric booster heater operation. When this field setting is not activated, the booster heater will still work if the ambient temperature drops below the value set in [7-04]. This is the backup mode of the domestic hot water heat pump. [-0] Status: defines whether the heat up can continue () or not (0) when the requested temperature set point is not reached during the programmed schedule timer operation. The p icon is blinking in case the heat up can not continue ([-0]=0). In case the reheat function is enabled, the p icon will stop blinking when the reheat operation has finished. [4] Miscellaneous [4-0] Simultanuous operation of booster heater and heatpump [4-0]=0 Simultanuous operation of the electric booster heater and heat pump is not allowed. [4-0]= Simultanuous operation of the booster heater and heat pump is only allowed during quiet mode. During quiet operation the heat pump operation sound is reduced by reducing the compressor frequency. This influences the heating capacity and increases the heat up cycle time. If required the electric booster heater can assist to heat up the domestic hot water tank to shorten the heat up cycle time. [4-0]= Simultanuous operation of the booster heater and heat pump is only allowed during powerful operation mode. The powerful operation mode is considered as an exceptional operation mode. If required during powerful operation the electric booster heater can assist to heat up the domestic hot water tank. [4-0]= Allows the simultanuous operation of electric booster heater and heat pump during quiet and powerful operation. [6] Miscellaneous [6-00] and [6-0]: The 'DT (temperature difference) for heat pump domestic water heating mode' field settings determine the temperatures at which heating of the domestic hot water by the heat pump will be started (i.e., the heat pump ON temperature) and stopped (i.e., the heat pump OFF temperature). When the domestic hot water temperature drops below the heat pump ON temperature (T HP ON ), heating of the domestic hot water by the heat pump will be started. As soon as the domestic hot water temperature reaches the heat pump OFF temperature (T HP OFF ) or the user set point temperature (T U ), heating of the domestic hot water by the heat pump will be stopped. The heat pump OFF temperature, and the heat pump ON temperature, and its relation with field settings [6-00] and [6-0] are explained in the illustration below. [6-00] Start: temperature difference determining the heat pump ON temperature (T HP ON ). See illustration. [6-0] Stop: temperature difference determining the heat pump OFF temperature (T HP OFF ). See illustration. T U <60 C T( C) T U T HP MAX T HP OFF T HP ON T HP MAX T U = 45 C [6-0] = 0 C [6-00] = 5 C T U = T HP OFF [6-00] T HP ON User set point temperature (as set on the user interface) Maximum domestic hot water tank temperature at sensor in domestic hot water tank by heat pump operation Heat pump OFF temperature Heat pump ON temperature [6-0] Booster heater economical timer: determines when the booster heater can start after the heat pump has started operating. This setting is only meaningfull when the simultanuous operation of the booster heater and heat pump is allowed ([4-0] is not set to 0). [6-0] Powerful mode priority: determines the priority when quiet operation mode and powerful operation mode are active at the same moment.

23 [7] Miscellaneous [7-0] DT for booster heater When the domestic water is heated and the domestic hot water set point temperature (as set by the user) has been reached, the booster heater will stop until the domestic hot water temperature drops a few degrees below the set point temperature, i.e. the booster heater ON temperature. The booster heater will start heating up the domestic water again. These degrees are specified by the domestic hot water step length field setting. Correct setting prevents the booster heater from repeatedly turning on and off (i.e. chattering) to maintain the domestic hot water set point temperature. [7-0] Domestic hot water step length: temperature difference below the domestic hot water set point temperature before the booster heater is turned on again.

This mixing valve shall secure that the hot water temperature at the hot water tap never rise above a set maximum value. This maximum allowable hot water temperature shall be selected according to local and national regulations. [7-0] Not applicable [7-04] T-ambient adaption: this field setting allows to adapt the minimum allowed temperature in the installation room for heat pump operation. WARNING It is very important that this value is not set to a temperature that can cause damage to the installation room! It must be set in a way so that condensation does not occur on the cold walls of the adjacent heated room. WARNING If the value of [7-04] is set lower than C, the correct unit operation can not be guaranteed and damage to the unit can occur. BH T U = 70 C [7-0] = C t [8] Automatic set point calculation [8-00] Set point (weekdays): starting temperature for automatic set point calculation during weekdays. [8-0] Set point (week-end): starting temperature for automatic set point calculation during week-end. NOTICE Because the domestic hot water demand is not known from the start and to avoid comfort problems this should be set to the customer estimated consumption set point. [8-0] Initial city water temperature To be able to start calculation of the automatic set point, [8-0] should be set to the current city water temperature when the unit is started. The outdoor temperature will influence the city water temperature, making it colder during winter time and warmer during summer time. [8-0] Reset demand: when this field setting is set to and power is reset, the automatic set point calculation is reset and calculation will start all over again. This setting is used when there is a permanent change in the user domestic hot water consumption pattern. When power is reset, initialisation is executed and this field setting will automatically be set to 0. [8-04] Domestic hot water tank volume: depending on which domestic hot water tank is used with the heat pump, the correct volume must be set: [8-04]=0 when the tank volume is 60 litres (EKHHS60) [8-04]= when the tank volume is 00 litres (EKHHS00) NOTICE If the setting of [8-04] is not set correctly, customers might have a hot water shortage when using the auto adaptive set point. So it is important to set this correctly! [D] Benefit kwh rate power supply Benefit kwh rate power supply [D-0] Unit connection to benefit kwh rate power supply: Defines whether or not the unit is connected to a benefit kwh rate power supply. If [D-0]=0, the unit is connected to a normal power supply (default value). If [D-0]= or, the unit is connected to a benefit kwh rate power supply. In this case the wiring requires specific installation like explained in "Connection to a benefit kwh rate power supply" on page 5. When parameter [D-0]= at the moment that the benefit kwh rate signal is sent by the electricity company, that contact will open and the unit will go in forced off mode ().
