To protect the floor and move the module box
(③)
more easily: place boards
(④)
under it, e.g. from
the packaging material.
13. Lift and hold nut
(①)
on the heating flow.
14. Slowly and carefully pull out the module box by
the carrying lugs
(②)
. Ensure that none of the
pipes are damaged
15. Pull out the module box completely and place it
on the boards.
6.2 Install the module box
1. Place the module box carefully in the bottom of
the housing and slowly and carefully push it in.
● 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
● Plug in the black rectangular connector at the
top of the module box
6.3 Install the hydraulic connections
NOTE
The heat source can be connected from the
top, right or left.
If the heat source will be connected at the side, the ca-
bles can be cut to a residual length of at least 250 mm
from the edge of the device (
“Dimensional dra-
wings“, page 30).
IMPORTANT
Damage to the copper pipes due to unacceptable
loading!
►
Secure all connections against twisting.
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.
