USER OPERATION AND MAINTENANCE
HP SERIES
PORTABLE PUMPS
25
For the "I" version, turn the key switch
and release when the pump has started.
6. PRIME PUMP: Hold priming lever ( )
down to prime the pump and establish
suction. Monitor suction and discharge
gauges to determine when suction is
established. Once suction is established
release the priming lever and make sure
the lever returns to the up position.
CAUTION: Do not run pump
for more than 45 seconds
without suction established.
NOTE: When the pump is
connected to a positive
pressure source priming is not
required. When using the
pump with a positive pressure
connected to the inlet ensure
the 1/4 turn valve on the
exhaust primer assembly is in
the closed position prior to
starting the pump.
7. ESTABLISH DISCHARGE: Once suction
is established as indicated by the
gauges, open the pump discharge
valve by rotating handle
counterclockwise.
8. ADJUST THROTTLE: Adjust throttle lever
to obtain the desired discharge pressure
on the discharge gauge.
CAUTION: Exhaust system
components may smoke
during the initial break-in
period. This smoking will stop
after the pump is run several
times.

2. Set speed control at part-throttle
