2 Safety
2.1 Designated application
The hydraulic unit, in conjunction with the outdoor unit, is suitable for
▪heating of heating water to VDI 2035,
▪mono-energetic and bivalent operation up to -20 °C external temperature,
▪room cooling,
▪domestic hot water preparation.
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
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 hydraulic unit transfers the heat supplied by the outdoor unit to the heating circuit.
An internal circuit reversal in the outdoor unit allows the hydraulic unit to be used for
cooling.

Condenser
In the condenser, the refrigerant releases the recovered energy to the heating water.
Heating circuit pump
The high efficiency pump pumps water through the heating circuit during heating
operation.
Domestic water feed pump
The 3 stage domestic water feed pump provides water to top up the water tank.
Non return valves
A non-return valve above the pumps prevents incorrect circulation in the pipework
system.
Sludge separator
The sludge separator filters impurities from the heating water and thus protects the
condenser.
Flow switch
The flow switch monitors the minimum flow in the water circuit.
Electric heating
If the external temperature is low or if there is a fault, the electric heating can support
the heat pump.
