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 models CLFG 61, CLFG 81 and CLFG 101 the eye bolts on the pump must be used.
The weight of the pumps are shown in the accompanying table.
Storage: CLFG 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 vacuum pump:
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 vacuum pump is too cold.
1.6 Oil mist separator blocked or contaminated.
1.7 Back pressure on the exhaust pipework is excessive.
2.
Insufficient suction capacity:
2.1 Inlet filters are obscured.
2.2 Suction pipe work is too long or too small.
3.
Vacuum pump does not reach ultimate vacuum:
3.1 Check for leaks on the suction side of the pump or on the system.
4.
Vacuum pump operates at an abnormally high temperature:
4.1 Ambient or suction temperature 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 and 1.7.
5.
Exhausted air contains visible oil mist:
5.1 Oil mist separator is fitted incorrectly.
5.2 Incorrect oil brand is used.
5.3 Problem as per 1.6, 1.7, 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 pump cylinder is worn. Solution: send your complete unit off for repair to the supplier or approved service agent.
6.3 The vacuum regulating valve is noisy. Solution: replace valve.
6.4 Blades are damaged.
6.5 The viscosity of lubricant is too high.
6.6 Problem as per 1.5.
7.
Water in lubricant i.e. Emulsification:
7.1 Pump pulls in water because of the application.
Solution: Fit water separators on to the vacuum side.
7.2 Pump operates only for a short time and does not reach normal operating temperature. Solution: Operate the pump with a closed suction port
until the operating temperature has been reached and then put on line to the application.
