8.4.2 Comparing the old/new oil level
While the air-conditioning system is being operated, some
of the compressor oil will spread in the refrigerant circuit.
The replacement compressor is already filled with 1.3 l of
compressor oil. Before replacement, compare the oil
levels of both refrigerant compressors via the sight glass
and adjust the replacement compressor as needed in
order to avoid overfilling the air-conditioning system (see
7.4.4). Note the minimum and maximum oil level.
Check, and adjust as needed, the oil level of the air-condi-
tioning system after commissioning.
8.4.3 Install the compressor
1. Set into the compressor pan
• Inspect the positioning of the foam in the
compressor pan (Fig. 809).
2. Insert and attach the compressor.
.
• Lift the compressor on the ring screw with suitable
lifting device and place into compressor pan with
side foam (3, Fig. 810).
NOTE:
The sight glass oil level must be well visible when
opening the compressor pan.
