6.6.2 Connecting refrigerant pipes 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 hydrokit or
All in One unit, tank and electrical heater) is disconnected from the electric supply.
!
IMPORTANT
The pipes can be routed out of the unit in four directions: to the front, back, right and left side.
Select the direction most suitable for the installation location.
Carry out the following steps to connect the prepared refrigerant pipes coming from the indoor unit
to the outdoor unit:
1. Open the outdoor unit (→ 6.5 Opening devices, p. 155).
2. Remove the selected pipe panel (2) and provide it with suitable holes for the pipes.
3. Mount the pipe panel again so that rain will not enter the outdoor unit.
4. Align the ared tube and the connecting pipe centrally and rst tighten the are nut by hand
and then with a torque wrench and an adjustable spanner to counter it. Ensure the correct
torques (→ Permissible tightening torques of refrigerant pipes (Outdoor units), p. 164).
5. Close the opening around the pipes entering the outdoor unit using thermal insulation or
putty (provided on site) to ensure that no gap is left open.
