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 calibra-
ted 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 fol-
lowing sounds; A high pitch whine is normal sound
from the impeller blades. As pump draws cooling air
from the vacuum relief valve a weak hissing should
be heard.
5. Measure the pressure. Compare with the dimension
point. Th
e pressure can be adjusted by adjustment of
the vacuum relief valve. See page 23 - Adjusting the
vacuum relief valve.
6. Check the function and tightness of the connected
exhaust system.
7. Open the number of outlets the system is dimen-
sioned for. Th
e vacuum relief valve should now be
totally closed.
8. It is normal that the pump becomes hot during ope-
ration.
