Install the compressor in the system
Carry out a leak test with refrigerant.
Make a test run. During this, check the oil level, the leak-tightness of the compressor, the
running noise, pressure, temperatures and the functioning of additional devices such as the
capacity regulation.
Checking the compressor
Working course
1. Evacuation/leak check of compressor
Connect the discharge and suction sides of the compressor to a vacuum pump
Evacuate the compressor from both sides; vacuum < 1,5 mbar. Check increase in pressure.
In case there is an increase in pressure, check the compressor for leaks und evacuate again.
Fill in the stipulated amount of oil (2,0 liters).
2. Carrying out the function test
General fastenings with fibrous or metallic flat gaskets
Remark: If the compressor is going to remain in the warehouse, charge it with nitrogen (at about
3 bar pressure) for protection.
Attention! Take the reminders for commissioning in the operating manual for FK
40 into account!
