2 Safety
2.1 Designated application
The outdoor unit is suitable for heating and cooling of refrigerant R410A.
The unit is only suitable for domestic application. It is not suitable for use in industrial
processes.
Improper use could:
▪endanger the health and safety of the user or third parties,
▪cause damage to the appliance or other material assets.
2.2 Procedure when refrigerant leaks
The outdoor unit is filled with refrigerant. When storing and installing the unit in a room
please observe:
Leaking refrigerant collects at the base of the unit. Inhalation may cause suffocation,
and even death.
Avoid open flames and spark generation.
▶Use protection provided on site to isolate the outdoor unit/system from the mains
supply.
▶Open doors and windows.
▶Leave the room.
▶Warn all tenants.
▶Notify refrigeration engineer.
2.3 Safety measures
Safety relevant fault conditions must be eliminated immediately.
2.3.1 Normal operation
▪All labels on the unit must be kept in a legible condition,
▪only operate the unit with its panels fitted,
▪stipulated settings, service and inspection work should be carried out at regular
intervals.
2.3.2 Electrical connection
For work carried out on live parts:
▪Observe the accident prevention instructions BGV A3 and adhere to local direc-
tives,
▪tools in accordance with EN 60900 should be used.

2.3.3 Refrigeration circuit
▪Only a competent person in accordance with §5 ChemKlimaSchutzV (Carbon
Chemical Regulation) may install, alter and service a refrigeration circuit.
▪Observe BG regulation "Operating works material" (BGR 500).
▪Wear safety glasses and work gloves when handling refrigerant.
▪Carry out leakage test with leak detecting device after each service and fault rec-
tification.
2.4 Disposal
Dispose of all materials used in a safe and environmentally friendly way. Observe local
regulations.
Dispose of refrigerant in the correct manner.

3.3 Function
The outdoor unit extracts heat from the outside air. The energy extracted is transferred
to the heating circuit by a refrigerant.
An internal circuit reversal means that the unit can also be used for cooling.

Fan
The fan draws ambient air through the evaporator.
Evaporator
The evaporator (heat exchanger) removes the heat energy from the intake air and
transfers it to the refrigerant.
Compressor
The compressor draws the refrigerant from the evaporator at low pressure and brings
it to a higher pressure and temperature level.
Condenser
The condenser (heat exchanger) is fitted in the hydraulic unit.
In the condenser, the refrigerant releases the recovered energy to the heating water.
Expansion valve
In the expansion valve, the pressure and temperature are reduced to the output level.
This allows the refrigerant in the evaporator to absorb heat again.
