ISTAATIO The air conditioning and hot-air heating units, the circuit breaker (I) and/or the remote control must be installed out of reach of persons who may be taking a bath or shower. Exploded view of the unit (See figure ) Water drip tray Heat exchanger module Switch box 4 Terminal strip Anti-vibration isolator -speed electric motor an drive assembly 8 Straight duct connector Configuration of the unit The heat exchanger connections can be switched over to the opposite side by carrying out the following procedure. (See figure 4) Remove the straight duct connector. Remove the drip tray. Remove the heat exchanger module by unscrewing the holding screws ( on each side + on the upper side and on the lower part). 4 Turn the heat exchanger module over 80 (vertical axis) and screw the module back onto the fan module. Adjust the position of the drip tray so that the sticking-out part extends below the hydraulic connections and fix it in place again. Screw the straight duct connector back to the heat exchanger module. Installing the unit Insert the supplied anti-vibration isolators in the 4 slots indicated for ceiling installation. ix the standard unit to the ceiling or wall using at least 4 of the 8 slots; or installation it is advised to use 8 threaded bars, screw anchors suitable for the unit's weight and to arrange for the positioning of the unit using 8 bolts ( in the lower part, and in the upper part as shown in figure ) and washers the diameter of which is suitable for inserting the slot and for then fixing the unit. Before tightening the lock nut, adjust the closing of the main nut so that the unit will slant correctly, i.e. for facilitating the discharging of the condensate (see figure ). The correct slant is achieved by tilting the inlet downwards as compared to the outlet until a difference in level of about 0 mm is obtained from one end to the other. ake the hydraulic connections with the heat exchanger and, for cooling operations, with the condensate discharge. Use one of the drains of the drip tray, visible on the outside of the unit's side panels. To connect the unit to the condensate discharge line, use a flexible rubber tube and fix it to the chosen discharge tube (Ø/8") by means of a metal clamp (use the discharge that is located on the hydraulic attachments side). To assist the draining of the condensate, slant the discharge tube downwards by at least 0 mm/m making sure that its entire route is clear and free from bendsor blockages. A few rules to follow Purge the air from the heat exchanger, with pumps stopped, by means of the air valves located adjacent to the attachments of the heat exchanger itself. The ducting, especially the outlet duct, must be insulated with anti-condensation material. Provide an inspection panel adjacent to the equipment for the maintenance and cleaning operations. Install the control panel on the wall. Choose a position that is easy to access for the setting of the functions and for detecting of the temperature. Try to avoid positions that are directly exposed to sun rays, or positions subject to direct hot or cold air currents. Do not place obstacles in the way that would prevent the correct reading of the temperature. IED WIRIG All field wiring and components must be installed by a licensed electrician and must comply with relevant local and national regulations. Carry out the electrical wiring after having turned the power off. or options, refer to the appropriate manual. Check that the power supply corresponds to the nominal power supply stated on the unit nameplate. Each unit requires a switch (I) on the power supply with a distance of at least mm between the opening contacts and a suitable safety fuse (). Power consumption is shown on the data plate fixed to the unit. ake sure to carefully execute the wiring in function of the combination unit/controller and this according to the correct wiring diagram delivered with every accessory. In order to make the electrical connections you must remove the panel covering the switch box (see figure ) to access the terminal strip. The power cables (power supply and control) must be routed to the terminal strip through the pwer supply cable intake holders on the side of the switch box.
