Page 16: Installation Of The Device
5 Installation of the device The lowest ceiling height in the room with the heat pump WP2 LF202S is 1900 mm; with the heat pump WP2 LF-302S it is 2200 mm. The device is designed to take the heat from the surrounding air or suck the air through air channels and blow it into the adjoining rooms or surroundings. -
Page 17: Minimal Clearance From The Device
The most common installation of the device enables it to draw air from rooms with a lot of excess heat. A part of heat is drawn from this air and then released into the surroundings. The air in kitchens, washing or sanitary rooms often has unpleasant odours, this is why it is released into the surroundings. -
Page 18: Levelling Of The Device
At least 1 m of space must be provided in front of the device for control and servicing purposes. If the air is drawn from the room device is located, the volume of the room must be at least 30 m 5.2 Levelling of the device CAUTION During operation, the device has to be placed in a vertical position to prevent... - Page 19 CAUTION Because different materials are used on the pipe installation, all connections on the device (cold and hot water, circulation, heat conductor) have to be in galvanic isolation; otherwise corrosion of connections can occur on the inner side of the buffer tank for DHW.

Page 20: Installation Of Air Ducts
CAUTION For normal operation of the expansion tank, it is necessary to perform proper adjustments of the tank’s working pressure. The pressure is adjusted according to the pressure of the water supply. The settings have to be checked every 6 months. 5.4 Installation of air ducts. - Page 21 On the air outlet side it is necessary to enable unobstructed air flow at least 1 m behind the air connection. On the side of the ceiling it is necessary to enable at least 20 cm of unobstructed air flow. NOTE The device must be installed in a manner which prevents mixing of the air on the intake and outlet.
