40 DRYPOINT® RA 1080-8800
 Compressor outlet
temperature too
high.

Find out the reason for the fault:
1. Excessive thermal load – re-establish the nominal conditions.
2. The inlet air is too hot – re-establish the nominal conditions.
3. The ambient air temperature is too high or the room ventilation insufficient – ensure
sufficient ventilation.
4. The condenser is dirty – please clean it.
5. The fan does not work – see the corresponding section.
6. The fan runs continuously – ensure perfect functioning of the power contactor of the
fan (see KV1/KV2 on the electric diagram) and/or of the pressure transducer (see BHP
on the electric diagram) – (air-cooled).
7. The hot-gas bypass valve needs to be re-adjusted – contact a specialist to have the
nominal calibration re-established.
8. The temperature of the cooling water is too low – re-establish the nominal conditions
(water-cooled).
9. The adjusting valve for the cooling-water flow needs to be re-adjusted - contact a
specialist to have the nominal calibration re-established (water-cooled).
10. Refrigerant gas leak – contact a technician for refrigeration plants.
 Condensation
pressure too high.

Find out the reason for the fault:
1. The ambient air temperature is too high or the air change insufficient in this area –
ensure sufficient ventilation (air-cooled).
2. The condenser filter is dirty – please clean or replace it (air-cooled).
3. The fan does not work – see the corresponding section (air-cooled).
4. The cooling water is too hot – re-establish the nominal conditions (water-cooled).
5. The cooling-water flow is insufficient – re-establish the nominal conditions (water-
cooled).
 Condensation
pressure too low.

Find out the reason for the fault:
1. The fan runs continuously – ensure perfect functioning of the power contactor of the
fan (see KV1/KV2 on the electric diagram) and/or of the pressure transducer (see BHP
on the electric diagram).
2. The ambient temperature is too low – re-establish the nominal conditions.
3. Air flows through the condenser although the fan is switched off – protect the dryer
against wind or external air flows (not caused by the fan of the dryer).
4. The cooling-water temperature is too low – re-establish the nominal conditions (water-
cooled).
5. The adjusting valve for the cooling-water flow needs to be re-adjusted - contact a
technician for refrigeration plants to have the nominal calibration re-established (water-
cooled).
6. Refrigerant gas leak – contact a technician for refrigeration plants.
7. Compressor does not work – see specific point.
