45° (in either direction). Do not lift unit by the holes in the panel assemblies! Flush the heating system prior to connecting the heat pump. The supplied strainer is to be fitted in the heat source inlet of the heat pump in order to protect the evaporator against contamina- tion. The brine must contain at least 25 % of a frost and corrosion protection agent on a monoethylene glycol or propylene glycol basis. The clockwise phase sequence must be observed when connecting the load line. Commission

For detailed instructions concerning the connection and functioning of the heat pump controller refer to the operating manual supplied with the controller. MOUNTING CAUTION! correct). 7 An all-pole disconnecting device with a contact gap of at least 3 mm (e.g. utility company disable contactor or power contactor) as well as a 3-pole circuit breaker with simultaneous tripping of all external conductors must be provided .

The additional heat consumption should be met using special devices provided by the customer. If a building is to be dried out in autumn or winter, we recommend installing an additional heating element (available as an accessory). ATTENTION! The device is not suitable for operation with a frequency converter. 2.2 Operating Principle Outside air is drawn in by the ventilator and fed via the evaporator (heat exchanger). The evaporator cools the air, i.e. it extracts heat from it. This extracted he

An incorrect setting may result in various error symptoms and an increased elec-tric power consumption. To correctly set the overflow valve, the following procedure is recommended: Close all of the heating circuits which may also be closed during operation (depending on the type of heat pump usage) so that the least favourable operating state - with respect to the water flow rate - is achieved. Normally, these heating circuits are those of the rooms located on the south and west sides of buildi
