8 Connecting the pipework
and cables to the outdoor
unit
This chapter describes the refrigerant pipe connections and the
electrical cable connections on the outdoor unit.
8.1 Refrigerant pipes
ATTENTION!
!
!
Work on the system must only be performed by authorised
and qualified after-sales service technicians!
Certain requirements with regard to pipe length and rise must
be complied with when installing refrigerant pipes. Once all re-
quirements have been fulfilled, certain preparations must be
made.
Once these are complete, the connecting pipe from the out-
door unit to the indoor unit can be connected.
8.1.1 Requirements for pipe length
and rise
The standard pipe length is 7.5 m. Up to a length of 15 m, no
additional refrigerant filling is required. For pipe lengths over
15 m, the system must be filled with additional refrigerant in ac-
cordance with the table.
*Example: When installing the 14 kW model at a distance of
50 m, 2100 g refrigerant must be added according to the fol-
lowing calculation: (50-15) x 60 g = 2100 g
NOTE
º
If the indoor unit is mounted 4 or more metres higher than the
outdoor unit, a cooling technology specialist must perform a
separate check to ensure that the devices for conveying the
oil up and down the pipes have been installed correctly in the
hot gas pipe.
NOTE
º
The rated output of the device corresponds to the standard
pipe length and the maximum possible length.
ATTENTION!
!
!
Incorrect filling with refrigerant could lead to faults during
operation.
1) Production operation (see model name label)
2) Installation operation (where possible, attach alongside the
maintenance connections for adding or removing refriger-
ant)
3) Total filling (1, + 2,)
8.1.2 Preparation for pipework
The preparation of the pipework takes place in five steps. One
main cause of refrigerant leaks is incorrect flanging. Flanging
must be carried out carefully and according to the following
steps.
Step 1: Cutting pipes and cables
Use the installation kit for pipework or the pipes purchased
from your local dealer.
Measure the distance between the indoor and outdoor
unit.
Cut the pipes slightly longer than the measured distance.
Step 2: Removing burrs
Remove all burrs from the interface of the pipework.
Hold the pipe end downwards so that no burrs can fall into
the pipe.
Step 3: Inserting screw nuts
Remove the screw nuts on the indoor and outdoor unit.
Insert the screw nuts into the deburred pipe.
No nuts can be inserted into the pipe after flanging.
