6.6.2 Connecting coolant pipelines to the outdoor unit
WARNING
Danger to life from electric shock
The devices are operated with 230-V or 400-V alternating current. Touching the live electrical
cables can be life-threatening due to electrical shock.
► Before opening the outdoor unit, make sure that the entire system (including hy-
dro-module or combination hydro-module, tank and E-heating element) is disconnect-
ed from the electric supply.
!
IMPORTANT
The pipelines can be installed in four directions from the device: front, back, to the right and to
the left. Select the direction most suitable for the installation location.
Carry out the following steps to connect prepared coolant pipelines coming from the indoor unit
to the outdoor unit:
1. Open the outdoor unit (→ 6.5 Opening devices, p. 148).
2. Remove the selected pipe collimator (2) and provide it with suitable holes for the
pipelines.
3. Reassemble the pipe collimator so that rain will not enter the outdoor unit.
4. Align the tube and valve centrally and rst pull the cap nut by hand and then with a torque
wrench and an adjustable spanner to counter it. Ensure the correct torques (→ Permissi-
ble tightening torques of the coolant pipelines - outdoor units, p. 159).
5. Lock the pipe entries into the outdoor unit using thermal insulation or putty knife (provided
on site) to ensure that no gap is left.
