The connection positions for pressure transmitters at the CS. series vary depending on compressor size. The following videos show the positions for a CS.85 compressor.
Attach T joint for mounting the low pressure transmitter
- Ring wrench / spanner SW 13
- Spanner SW 14
The connection positions for pressure transmitters at the CS. series vary depending on compressor size. The following videos show the positions for a CS.85 compressor.
Mount the low pressure transmitter
- Spanner SW 16 (counter-hold with spanner SW 14)
- Suitable refrigeration compressor oil
- Torque spanner
- Tightening torque: 35 Nm
Attach cable of low pressure transmitter
Mount the high pressure transmitter
- Spanner SW 16 (counter-hold with spanner SW 14)
- Suitable refrigeration compressor oil
- Torque spanner
- Tightening torque: 35 Nm
Attach cable of high pressure transmitter
Create a vacuum at the high pressure side (at least -0,5 bar)
This ensures that no oil leaks through the connection when the discharge gas temperature sensor gets replaced.
- Vacuum pump
Remove existing discharge gas temperature sensor (PTC) and install new discharge gas temperature sensor (NTC)
- Work quickly!
- Ratchet wrench with socket spanner size 17
Mount new discharge gas temperature sensor (NTC)
- Ratchet wrench with socket spanner size 17
- Torque spanner
- Tightening torque: 17 Nm
Switch off and remove vacuum pump
Attach cable of new discharge gas temperature sensor (NTC) and screw in by hand
Open cable bushing at terminal box
- Screwdriver handle
Attach screwed cable gland M25x1,5
Push through screwed cable gland
- Screwdriver
Guide all cables into terminal box
