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 ZEPHYR the eye bolt must be used.
The weight of the VLR are shown in the accompanying table.
Storage: ZEPHYR units must be stored in dry ambient conditions with normal humidity. We recommend for a relative humidity of over 80% that
the pump should be stored in a closed container with the appropriate ”drying” chemicals.
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:
1.1 The incoming voltage and frequency does not corresponds with the motor data plate.
Solution: Adjustment of the mains voltage.
1.2 The connections on the motor terminal block is incorrect.
Solution: Check connections on the motor terminal block or the plug.
1.3 Incorrect setting on the motor starter.
Solution: Check the setting of 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).
2.
Insufficient suction capacity:
2.1 Protection mesh is blocked.
Solution: Clean the protection mesh.
2.2 Suction pipework is too long or too small.
Solution: Use bigger pipe diameter, avoid restriction.
3.
ZEPHYR VLR does not reach ultimate vacuum:
3.1 Leak on the suction side of the pump or on the system.
Solution: Check the suction side and the pipework for pressure losses.
4.
ZEPHYR operates at an abnormally high temperature:
4.1 Ambient or suction temperature too high.
Solution: The ambient and suction temperatures must be between 5 and 40° C.
4.2 Cooling air flow is restricted.
Solution: The cooling air entries (E) and the cooling air exits (F) must have a minimum distance of 20 cm from any obstruction.
5.
ZEPHYR emits abnormal noise:
5.1 Contamination of the rotary lobes.
Solution: Clean pumping chamber and rotary lobes.
