8. Insert the U-clip
(②)
into the floor of the valve motor.
9. Ensure that the U-clip has latched into position
correctly:
Valve motor sits securely on the 3-way changeo-
ver valve.
Both prongs of the U-clip sit on the lug.
The tips of the U-clip are visible by approx. 2 mm
(not significantly more
!).
10. Screw the front panel of the module box.
8 Insulate hydraulic connections
1. Insulate heating circuit and heat source according
to the local regulations.
2.
Open shut-off devices.
3.
Perform a pressure test and check for leaks.
4. Insulate the internal piping of the module box with
the insulation material from the separate pack
included.
5. Insulate external piping on site.
6.
Insulate all connections, fittings and pipes.
7.
Insulate heat source so that it is vapour-diffusion
tight.
8. Insulate the heating circuit of units with cooling
vapour-diffusion tight too.
9.
In units with cooling and capacity 14 kW and
higher, insulate the venting valve at the cold heat
exchanger too so that it is vapour-tight. To do this,
glue the insulation strips on top of each other
(
separate pack)

Set the overflow valve
NOTE
●
The activities in this section are only nec-
essary for in-line tank integration.
● Complete the worksteps quickly, otherwise
the maximum return temperature can be
exceeded and the heat pump switches to
high-pressure fault.
● Turn the adjusting knob at the overflow
valve to the right to increase the tempera-
ture difference (the temperature drop), turn
it to the left to reduce it.
System is running in heating mode (ideally in cold
condition).
The IBN assistant already provides the option, in the
event of the integration of the storage tank in series to
adjust the overflow valve according to to the hydrau
-
lic system.
