AIR FILTERS, START--UP SCREENS AND TEST
COUPON
If used on Wet Vacuum, servicing the
air filters is one of the most important
maintenance operations to be per-
formed to insure long pump life.
1.
Filters in the system should be checked and
replaced periodically.
2.
Start--up screens are recommended to be
installed at the inlet side of the pump.
3.
Test coupon is recommended downstream of the
last pump to monitor any corrosion or scaling in
the system.
In all cases refer to the filter manufacturer’s service
instructions. Due to the many types of filters, it is not
practical to give specific instructions covering all models.
No matter what type of filter is used,
always make sure all seats, gaskets,
clamps and hose connections on the
filter and inlet line are absolutely air
tight. Each time the filter is serviced,
inspect interior of the pump for dirt.
