WORKING CONDITIONS
The heat pump can be used as heat source for heating or cooling and for heating of water.
Working environment:
environment by ČSN 33 2000-3 for outside unit AA2-AA5; AB7; AD3
environment by ČSN 33 2000-3 for inside unit. AA5; AB5
The heat pump musn´t be placed and installed in environment with the risk of explosion of
combustible gases by ČSN 33 2000-3.
Technical parameters of electric suply:
rated voltage 3x400/230V +/-10% 50Hz
maximal input power according to the output table
electrical class TN-C-S ČSN EN 33 2000-3
protection class ČSN EN 60335-1
protection cover outdoor unit IPX4
indoor unit IP40/20
Refrigerant circuit
refrigerant HF R410A CH F /C HF - 50/50 (filling by type)
2 2 2 5
Maximal pressure 4,2 MPa (gas), 1,05MPa (liquid)
max. working overpressure 2,5bar
min. working overpressure 0,8bar
max. working temperature 60°C
Refrigerant exchanger freeze
The basic frost protection of exchanger refrigerant/water is to ensure minimal flow througth exchanger .
This crash of refrigerant exchanger threatens only during defrosts. It´s necessary to ensure there is not any
regulatory element in the heating circuit which should close or significantly constrict the circuit of the heating
water. During initial startup of the heat pump or after it´s shutdown the heating water must have temperature
of at least 10°C. Minimal water flow of heating water is 400 l/hr.
