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 units SMV the eye bolt on the pump must be used.
The weight of the blowers are shown in the accompanying table.
Storage: COVAC units must be stored in dry
ambient conditions with normal humidity. We
recommend for a relative humidity of over 80%
that the pump units should be stored in a closed
container with the appropriate drying agents.
Disposal: The wearing parts (as listed in the
spare parts lists) should be disposed of with due
regard to health and safety regulations.

3. Cooling (pictures ᕣ and ᕤ)
The air slots for the cooling air exits (F) in the
grill (G
1
) or the space between the cooling fins (E
1
)
may become clogged by dust. They can be
cleaned, by blowing out with compressed air,
after removing the cover plates (G
2
) and (G
3
).
4. Coupling (picture ᕥ)
The coupling rubbers (k) are wearing parts and
should be checked regularly. When the coupling
rubbers are worn this can be detected by a
knocking sound when the blower is started.
Defective coupling rubbers can cause
extensive damage and even in some
extreme cases break the blower shaft.
To check the coupling, stop the motor (m) and
isolate. Remove the screws (s
5
). Pull off the
motor together with the motor side coupling
half (q). If the coupling rubbers (k) are damaged
remove the circlips (l) from the coupling bolt (r)
and exchange the coupling rubbers (k). Leave
the spacer (p) in place, check the coupling bolts (r)
for any wear and replace if necessary. To re-
place, screw off motor flange cover (n), remove
the shaft nut (w
1
) with spring shim (u
1
), pull off
the coupling (q
1
) from the blower shaft. Remove
the nut (w) with washer (u) and exchange the
coupling bolts.
Re-assemble in reverse order.
Trouble Shooting:
1.
Vacuum pump does not reach operating speed when starting:
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.
2.
Motor starter cuts out blower:
2.1 Problem as per 1.1 and 1.2.
2.2 Incorrect setting on the motor starter.
2.3 Motor starter trips too fast.
Solution: Use a motor starter with a time delay trip (version as per IEC 947-4).
2.4 Back pressure on the exhaust pipework is excessive.
3.
Insufficient suction capacity:
3.1 Inlet filters are obscured.
3.2 Suction pipe work is too long or too small.
3.3 Leak on the pump or on the system.
4.
Vacuum pump does not reach ultimate vacuum:
4.1 Check for leaks on the suction side of the pump or on the system.
5.
Vacuum pump operates at an abnormally high temperature:
5.1 Ambient or suction temperature is too hot.
5.2 Cooling air flow is restricted.
5.3 Problem as per 2.4.
