POSITIONING CONNECTION BOX
The position of the motor connecting box is
adjustable. Referring to Figure 3, the position
can be changed by removing the motor fan
cover, unscrewing the frame bolts, and turning
the motor casing and connecting box
subassembly together to proper position.
Finally, screw the frame bolts tight, and put the
fan cover back.

OPERATION AND MAINTENANCE–SECTION D
! WARNING !
The pump cannot be operated with
discharge outlet fully closed. Doing so
will raise the liquid temperature
abnormally, and quickly damage pump.
! WARNING !
The pump cannot be used to transfer
explosive liquids.
Extra protective gear is required if the
working liquid temperature exceeds
140°F to avoid scald hazard.
The pump should not be used to transfer
toxic or contaminated liquid. Warranty
will be void if the pump application is not
in compliance with the installation and
operation procedures.
FINAL CHECKS
Before starting the pump, verify:
1. Pump rotation–the rotating direction
should be counterclockwise viewing
from fan cover end.
2. Piping and joints are fitted carefully to
prevent leaks.
3. Check that foot and air vent bolts are
secure and tighten if loose.
4. The pump has been filled with liquid and
air vented as described in the START
UP instructions below. Failure to do so
will damage the bearing and mechanical
seal.
5. The suction filter is clear of obstruction.
START UP
1. Start motor, verify motor is turning and
is turning in the right direction.
2. Open outlet valve, adjust it to the
required working condition. Suggested
flow is 0.5 to 1.3 times of the pump’s
rated flow.
3. Check pressure meter on pump’s
discharge for fluctuations in pressure
and observe pump for vibration. If
pressure drops/vibration indicate air in
the liquid, loosen air vent bolts to vent
air, retighten bolts once pressure
stabilizes and vibrations stops.
4. Observe for changes in the sound of
pump operation. If there are any
abnormal noises, pump should be
stopped and checked immediately.
SHUT DOWN
1. Close outlet valve slowly.
2. Switch off the power.
