To solve the error code
INFORMATION
It is recommended to perform the checks in the listed
order.
1 Perform a check of the high pressure switch. See
pressure switch" on page 27.
Possible cause: Faulty high pressure switch.
2 Perform a check of the refrigerant circuit. See
circuit" on page 53.
Possible cause:
▪ Stop valve is closed,
▪ Clogged refrigerant circuit,
▪ Refrigerant circuit NOT charged correctly,
▪ Humidity in the refrigerant circuit,
▪ Non-condensables in the refrigerant circuit,
▪ Leaking refrigerant circuit.
3 Perform a check of the main PCB. See
page 35.
Possible cause: Faulty main PCB.
4 Perform a check of the inverter PCB. See
PCB" on page 34.
Possible cause: Faulty power module = inverter PCB.
5 Check if the power supply is conform with the regulations. See
"3.1 Power supply" on page 52.
Possible cause:
▪ Faulty or disturbance of the power supply (imbalance
>10%),
▪ Power drop,
▪ Short circuit.
INFORMATION
If all procedures listed above have been performed and the
problem is still present, contact the helpdesk.
