the housing and slowly and carefully push it in.
● For units up to 12 kW capacity: Lift and hold
nut on the heating flow
●
Lift up pipes so that they do not get damaged
2. Attach the two side retaining screws.
3. Connect the hydraulic connections. At the
same time, replace O-rings on the heat pump
connections (
separate pack included).
4. Perform pressure test and insulate pipes with the
enclosed insulation hoses (
separate pack).
5. Connect the electrical cables:
●
Plug both connectors into the electrical control
cabinet. Ensure that the connectors move eas-
ily and the lugs latch into position

ATTENTION
Damage to the copper pipes due to unacceptable
loading!
►
Secure all connections against twisting.
NOTE
The heat source can be connected from the
top, right or left.
The heat source system has been installed in
accordance with the specifications (
planning &
design manual, dimensioned diagrams,
installation plans).
Cross-sections and lengths of the pipes for the
heating circuit and heat source are dimensioned
adequately.
The free pressure of the circulation pumps
produces at least the minimum throughput
required for the unit type (
“Technical data /
Scope of supply”, from page 24).
The cables for the heat source and the heating
are fixed to the wall or ceiling via a fixed point.
Cut off the lines to the heat source
NOTE
This step is only required for units with 14 kW
