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.
! CAUTION !
This pump must be primed before start
up.
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. The pump has been filled with liquid as
described in the
START UP
instructions
below. Failure to do so will damage the
bearing and mechanical seal.
4. The suction filter is clear of obstruction.
START UP
1. Do not start the pump until it has been
filled completely with liquid.
2. To fill pump in an inverse pouring
system:
a. close the pump outlet valve
b. release air vent screw on the pump
head
c. open the inlet valve slowly until stable
water flows from the air vent screw
d. tighten air vent screw
e. open the check valve in the inlet
pipeline completely
3. To fill pump in an open system (fill pump
when liquid surface is lower than the
pump):
a. a check valve should be installed on
the discharge pipe
b. close the pump outlet valve
c. release air vent screw on the pump
head
d. fill the liquid in the pump through the air
vent screw hole until pump and inlet
pipe are fully filled with liquid
e. tighten air vent screw
