SAFETY WARNINGS
BEFORE OPERATING OR
INSTALLING THIS PUMP, READ
THIS MANUAL AND FOLLOW
ALL SAFETY RULES AND
OPERATING INSTRUCTIONS.
CAREFULLY READ THESE SAFETY
SAFETY
MESSAGES IN THIS MANUAL AND ON
PUMP.
CAUTION: DO NOT OPERATE THIS PUMP DRY.
Review instructions before operating.
•
• Never exceed recommended RPM.
• Ensure proper rotation as indicated by arrow on pump casing.
These pumps will operate satisfactorily at vertical lifts up
to 25 feet when driven at full speed. In offset installations,
a ) PUMP LOCATION: The pump should be located on a fi rm
and level foundation in order to provide the best possible
working conditions. If the pump is not properly placed
or blocked, it may creep due to vibration. Locating the
pump as close as possible to the source of water supply
reduces the friction loss in the suction hose and provides
for maximum capacities.
b ) SUCTION HOSE: The suction hose should be the same size
as that of the pump suction tapping and should be checked
for collapsed inner lining, cuts, breaks, etc. If the pump is
installed any appreciable distance away form the source of
water supply, the suction hose should be increased in size
WARNING: DO NOT RUN THE PUMP BEFORE PRIMING IT; THE SEAL AND IMPELLER COULD BE PERMANENTLY
DAMAGED.
a) PRIMING: Never operate the pump dry as this may dam-
age the seal. To prime, remove the priming plug and fi ll
the pump casing with water. Replace the priming plug and
start the unit. If an exceptionally long suction line is used,
the water in the pump casing may become overheated or
vapor locked. Should this occur, replace the water in the
pump casing with cold water and continue priming.

• Ensure input drives are properly aligned and guarded

• Keep all shield guards in place. (This label is located on
the transmission housing.)
friction losses in the suction hose must be taken into
consideration.
to reduce friction loss (this also increases the priming time).
To prevent air pockets from forming in the suction line, the
suction hose must always slope down toward the source
of water supply. Thread compound should be used on all
pipe joints and connections should be thoroughly tightened.
A strainer should be installed on the bottom of the suction
hose and should be properly submerged.
c) WIRING: On electric motor driven units check the rotation
of the pump with the arrow on the pump casing. In the
event of wrong rotation, refer to instructions furnished with
motor. The rotation of three phase motors can be changed
by interchanging any two leads to the motor.
b) PRIMING UNDER PRESSURE: Should it be necessary
to prime under pressure, place a check valve on the dis-
charge of the pump and a pet cock ball type 'air bleeder'
in place of the priming plug, or an air bleed line with a gate
valve connected to the discharge line (see Fig. 1). It will
then be possible for the liquid to remain in the discharge
pipe and allow the pump to draw the air bleeder thereby
