2 Important information
Caution! The heat pump must be located in a frost-free environment!
Caution! The installation may only be commissioned if the heating system is filled and bled. Otherwise
the circulation pump can be damaged.
Caution! If the electrician wishes to test his connections before the above is carried out, this should only
done when it has been checked that the heat pump, the electric boiler, the compressor and the heat
shields are disconnected.
Caution! When filling the coolant system the coolant pump must be operating but one must ensure that
the compressor and the heat transfer pump cannot start.
The system can be considered maintenance free but certain checks are necessary.
Before changing the control computer’s settings, first find out what these changes mean.

2.1 Refrigerant
The heat pump’s cooling system (refrigerant circuit) is filled with R4 10A refrigerant.
Caution! Work on the refrigerant circuit must only be carried out by a certified engineer!
Caution! Fire risk R4 10A is not combustible or explosive in normal conditions.
Toxicity
In normal use and normal conditions the refrigerant has low toxicity. However, although the toxicity of the refrig‐
erant is low, it can cause injury (or be highly dangerous) in abnormal circumstances or where deliberately abused.
The refrigerant vapour is many times heavier than air and in enclosed spaces, below the level of the door for
example, and in the event of leakage, large concentrations can occur with the risk of suffocation because of lack
of oxygen. Spaces in which heavy vapour can collect below the level of the air must therefore be well ventilated.
Note! This appliance is intended to be used by expert or trained users in shops, in light industry and on
farms or commercial use by lay persons.
