Safety i nstructions / s tandards a nd r egulations
The heat pump system must be sited, installed, set up and commissioned by
a qualified contractor, in compliance with the applicable statutory regulations,
ordinances and directives and the installation instructions.
The tilting angle of the heat pump during transport must be no greater than 45°.
Under no circumstances must the components and pipework of the refrigerant
circuit, the heating circuit or the heat source side be used to transport the
appliance.
The heat pump must only be operated with outdoor air as the heat source.
The air-conducting sides must not be constricted or obstructed.
For safety reasons, the power supply to the heat pump and the control unit must
not be interrupted, even outside the heating season.
Reason: No monitoring of heating circuit pressure, no frost protection, no anti-
seizing pump protection.
The appliance may only be opened by a qualified contractor.
Before opening the appliance, all electrical circuits must be isolated
from the power supply. Take precautions to prevent the fan from starting up
unintentionally. Starting up the fan with the outdoor unit open can result in serious
injury. The system must be isolated from the power supply across all poles and
safeguarded against reconnection.
Work on the refrigerant circuit must only be carried out by a qualified contractor.
Do not use Teflon sealant in the heating circuit, as this may result in leaks.
Never treat appliance surfaces with scouring agents or cleaning agents containing
acid or chlorine.
When siting the heat pump, position and install it securely, to prevent it slipping or
sliding during operation.
The outdoor unit may only be installed outdoors.
Only replace faulty components with original WOLF spare parts.
Observe specified electrical fuse ratings (see specification).
Any damage or loss resulting from technical modifications to WOLF control units is
excluded from our warranty.
Risk of water damage and faulty operation through freezing.
The heat pump is automatically protected from frost when it is switched ON.
The local power supply utility must be notified when a heat pump is installed.
