Test Running

1. Verify that the power is locked out. Inspect
the belt tension (Figure B next page), rotate
the pump and listen for any sound indicating
worn bearings or misaligned impellers.
Check that the inlet and outlet are properly
connected. Also check that the vacuum relief
valve is connected.
2. Mount the covering panels. Check that no
persons can be hurt if the pump starts and
that all outlets are closed.
3. Connect a manometer for negative pressure
calibrated to min. -50 kPa to the suction side
as close to the pump as possible.
4. Power up the pump and listen carefully for
the following sounds; A high pitch whine is
normal sound from the impeller blades. As
Service
The pump should be inspected at least twice a year
and lubricated according to the lubrication intervals.
See page 17.
1. Start the pump and listen for abnormal sounds.
When all outlets are closed a weak hissing
sound should be heard from the vacuum relief
valve.
2. Shut off the pump and lock out the electrical
service.
3. Remove the protective panels from the pump.
4. Rotate the pump manually and listen for any
sounds indicating a worn bearing or misligned
impellers.
5. Check the condition and tension of the drive
belts. The drive belts are matched, therefore
new and old belts should never be used to-
gether. Always change the whole set. (A).
Changing the belts
- Lift the motor mounting plate with nut (1).
- Change belts.
- Tighten the belts with nut (2) and adjust to the
tension illustrated (B).
pump draws cooling air from the vacuum
relief valve a weak hissing should be heard.
5. Measure the pressure. Compare with the di-
mension point. The pressure can be adjusted
by adjustment of the vacuum relief valve.
See page 17 - Adjusting the vacuum relief
valve.
6. Check the function and tightness of the con-
nected exhaust system.
7. Open the number of outlets the system is
dimensioned for. The vacuum relief valve
should now be totally closed.
8. It is normal that the pump becomes hot during
operation.
