Fault Possible cause Troubleshooting
Insufficient refrigerant / underfilling
1. Check refrigeration circuit for leakage.→Page 51
2.
If no leak was found.
- Repair refrigeration circuit.→Page 60
Blockage / partial blockage at bottlenecks (e.g. capil-
lary tube, magnetic valve) resulting from contamination
▶
Rinse refrigeration circuit.→Page 59
No cooling power Compressor not operating
Compressor operating of continuously
Stop valve closed
1. Check electrical connections.
2. Check voltage (198 VAC - 254 VAC).
3. Check resistance (5 Ω - 100 Ω).
4. Measure input current (0.5 A - 1.2 A).
5. Check compressor (quick test)→Page 52.
6. Quick stop valve→Page 53 (if applied).
Protective conductor connection on compressor de-
tached
Compressor vibrations
Compressor operating of continuously
Stop valve closed
1. Check compressor electrical connections.
2. Install cable harness [00610943].
Filling pipe on compressor too short
Compressor filling pipe and customer service
filling pipe cannot be connected with a Lokring
Compressor filling pipe was squeezed out in the fact-
ory
1. Install a T-piece Lokring connector with Schrader valve [00066020]
(6 mm / 8 mm, brass) or [00066030] (6 mm / 8 mm, brass) for filling
on suction side.
2. Evacuate the refrigeration circuit via the valve.→Page 61
3. Fill refrigeration circuit.→Page 63
