Appendix:
Repair on Site: For all repairs on site an electrician must disconnect the motor so that an accidental start of the unit cannot happen.
All engineers are recommended to consult the original manufacturer or one of the subsidiaries, agents or service agents. The address of the
nearest repair workshop can be obtained from the manufacturer on application.
After a repair or before re-installation follow the instructions as shown under the headings ”Installation and Initial Operation”.
Lifting and Transport: To lift and transport the DCLF...D units the eye bolt on the pump must be used.
The weight of the pumps are shown in the accompanying table.
Storage: DCLF...D units must be stored in dry ambient conditions with normal humidity. If a pump needs to be stocked for a period longer than
3 months we would recommend using an anticorrosion oil rather than the normal lubricant.
Disposal: The wearing parts (as listed in the spare parts lists) should be disposed of with due regard to health and safety regulations.

Trouble Shooting
1.
Motor starter cuts out compressor:
1.1 Check that the incoming voltage and frequency corresponds with the motor data plate.
1.2 Check the connections on the motor terminal block.
1.3 Incorrect setting on the motor starter.
1.4 Motor starter trips too fast.
Solution: Use a motor starter with a time delay trip (version as per IEC 947-4).
1.5 The compressor is too cold.
1.6 The regulating valve is dirty causing excess pressure.
2.
Insufficient pressure capacity:
2.1 Inlet and/or exhaust filters are obscured.
2.2 Suction pipe work is too long or too small.
3.
Compressor does not reach overpressure:
3.1 Leak on the compressor or on the system.
3.2 Blades are damaged.
3.3 Motor rating selected was too small.
4.
Pressure/vacuum pump operates at an abnormally high temperature:
4.1 Ambient or suction temperature is too high.
4.2 Cooling air flow is restricted.
4.3 The viscosity of lubricant is too low.
4.4 Problem as per 1.6.
5.
Exhausted air contains visible oil mist:
5.1 Oil sieves are fitted incorrectly or are dirty.
5.2 Incorrect oil brand is used.
5.3 Problem as per 4.1, 4.2 and 4.3.
6.
Unit emits abnormal noise:
Note: A knocking noise from the rotor blades is normal when cold starting as long as it disappears within two minutes with increasing operating
temperature.
6.1 The coupling rubbers are worn (see under “servicing”).
6.2 The compress cylinder is worn. Solution: send your complete unit off for repair to the supplier or approved service agent.
6.3 The regulating valve is noisy. Solution: replace valve.
6.4 Blades are damaged.
6.5 Blades are hindered through oil-coal deposits at the gliding motion in the rotor slot.
Solution: Application of synthetic lubricating oil. If noise does not disappear, overhaul the DCLF...D through the supplier or approved service
agent.
6.6 The viscosity of lubricant is too high.
6.7 Problem as per 1.5.
7.
Water in lubricant i.e. Emulsification:
7.1 Compressor pulls in water because of the application.
Solution: Fit water separators on to the suction side.
