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.
In particular,observe the Drinking Water Ordinance [Germany].
Maintenance work must only be carried out by a qualified heating contractor.
Regular maintenance and the exclusive use of original Wolf spare parts are
crucial for trouble-free operation and a long service life for your appliance.
We therefore recommend you arrange a maintenance contract with your local
heating contractor.
A significant amount of energy can be saved by operating the DHW cylinder
at a temperature below 55 °C.
The ideal operating temperature range is 50 - 55 °C.
Heat losses and scaling are significantly reduced in this range.
Wolf heat pumps require special DHW cylinders for domestic hot water heating;
these are available from the Wolf range of accessories.
The cylinders are made of S235JR steel and come with a quality certificate.
The indirect coil surface area in the DHW cylinders must be at least
0.25 m² per kW of heating output.
The appliance may only be opened by a qualified contractor.
Before opening the appliance, all current circuits must be isolated from the
power supply (only for CPM-1).
Never treat appliance surfaces with scouring agents or cleaning agents
containing acid or chlorine.
For installation in Austria:
Observe the ÖVE regulations and requirements and those of your local
power supply utility.
Observe the specified electrical fuse ratings (see Specification).
Only replace faulty components with original Wolf spare parts.
Any damage or loss resulting from technical modifications to Wolf control
units is excluded from our warranty.
If the DHW temperature is set above 60 °C or when pasteurising at a
temperature in excess of 60 °C, always ensure that cold water is mixed in
with the hot (risk of scalding).
Risk of water damage and faulty operation through freezing.
The heat pump is automatically protected from frost when it is switched on.
Observe the Drinking Water Ordinance [Germany].
