2. Attach the two side retaining screws.
3. Connect the heating ow and hydraulic
connections. At the same time, replace O-rings
on the heat pump connections (separatepack
included).
4. Perform pressure test and insulate pipes with the
enclosed insulation hoses (separatepack).
5. Connect the electrical connections.
–
Plug in 2 white connectors at the bottom of

6.3 Install the hydraulic connections
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 specications ( 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” on page 24).
