Operating and installation instructions for system
components
Note Please see appliance operating and installation in-
structions for information on the "Guarantee" and
"Environment and recycling".
2. Safety
Only qualied contractors should carry out installation, com-
missioning, maintenance and repair of the kit.
2.1 General safety instructions
We guarantee trouble-free function and operational reliability
only if original accessories and spare parts intended for the
appliance are used.
2.2 Instructions, standards and regulations
Note Observe all applicable national and regional regula-
tions and instructions.
2.3 Intended use
The compact heat pump installation is intended for heating
heat pumps without integral heating circuit pump.
Any other use beyond that described shall be deemed inap-
propriate. Observation of these instructions and of instructions
for any accessories used is also part of the correct use of this
appliance.
3. Kit description
The compact heat pump installation includes all required com-
ponents for hydraulic connection of the heat pump to buer
cylinders with 200, 400and 700l capacity. Select and retrot
the heating circuit pump according to the system in DN25.
3.1 Standard delivery
The kit is supplied in pre-assembled individual parts. All pre-as-
sembled components are factory sealed.
Note A gravity brake is tted in the buer cylinder connec-
tor.
The opening pressure is 400mmWC.

 Screw the kit components and the heating circuit pump
together and tighten by hand.
 Fit the components and the heating circuit pump on the
cylinder.
 Retighten the ttings.
 Fit the expansion vessel and the drain valve.
 Fit the heat pump ow and return to the heat pump.
Note The WPKI5 safety valve must not be able to be isolated
from the heat source.
Note When there is a danger of frost in alternative opera-
tion, a drain valve must be installed on site to drain an
external air source heat pump (WPL and connection
hoses).
Note All shut-o devices are tightly sealed ball shut-o
valves.
 Only use an open-ended spanner (AF8) to open
and close the ball shut-o valves.
4.1 Heating circuit pump (cylinder charging
pump)
A corresponding heating circuit pump can be selected based
on the characteristic curves for the pumps and the pressure
loss from the compact heat pump installation.
Depending on the heat pump type, we recommend a heating
circuit pump from the following table for a standard system.
