6.2 Install the module box
1. Place the module box carefully in the bottom of
the heating station 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 in 2 white connectors at the bottom of the
electrical control cabinet. Ensure that the con-
nectors move easily and the lugs latch into po-
sition
● Plug in the black rectangular connector at the
top of the module box
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 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.
Install the compression fittings and ball
valves
ATTENTION
Leaks or fracture of the union nut due to excessive
force!
1.
Check pipe ends for scratches, dirt and deforma
-
tion.
2.
Check proper position of the clamping ring on the
fitting.
3. Push the pipe through the clamping ring up to the
limit stop in the fitting.
4. Tighten the union nut hand-tight and attach water-
proof marking.
5.
Tighten union nut with ³/4 rotation.
6.
Check connection for leaks.
If the connection leaks:
1.
Undo connection and check pipe for damage.
2. Tighten the union nut hand-tight and retighten
with the open-ended spanner with 1/8 to 1/4 turn, as
the clamping ring is already in a clamping posi-
tion.
