SAFETY WARNINGS
BEFORE OPERATING OR
INSTALLING THIS PUMP, READ
THIS MANUAL AND FOLLOW
ALL SAFETY RULES AND
OPERATING INSTRUCTIONS.
SAFETY
CAREFULLY READ THE SAFETY MESSAGES IN THIS MANUAL AND ON
THE PUMP.
CAUTION
DO NOT OPERATE THIS PUMP DRY!
•
• Review instructions before operating.
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding must comply
with the National Electrical Code (NEC) and with any local codes and
ordinances. Employ a licensed electrician.
FOR DUAL VOLTAGE MOTORS:
Voltage change instructions are located on motor label or on wiring
access cover.
WARNING - RISK OF ELECTRICAL SHOCK
• Employ a licensed electrician to provide electrical power to the motor.
• To reduce electrical shock hazard, ensure that motor is
grounded and terminal cover is in place.
• Keep motor operating area as dry as possible.
• Always disconnect power before servicing.
• Not investigated for use in swimming pool areas.
APPLICATION
This pump is suitable for installations where the vertical distance from
the pump to the water level does not exceed 25 ft.(7.6m)*, including
friction loss. In off-set installations, friction losses in the suction pipe
must be taken into consideration.
*Varies with elevation above sea level.
INSTALLATION
a) PUMP LOCATION: The pump should be installed in a clean, dry
and ventilated location which provides adequate drainage and
room for servicing and protection from freezing temperatures. It
should be bolted down evenly on a good foundation, preferably
concrete, to prevent the development of unnecessary stress.
Locating the pump as close as possible to the source of water
supply reduces the friction losses in the suction pipe and provides
for maximum capacities.
b) SUCTION PIPE: It is recommended that only new clean pipe
or hose be used and the size be the same as that of the pump
suction tapping. If the pump is installed any appreciable distance
away from the source of water supply, the suction pipe should be
increased by one size (this would increase the priming time). The
suction pipe must always slope upwards from the water source
to the pump to avoid air pockets in the line. In cases where the
pump has to be reprimed often and it is not necessary that a lot
of water be delivered, it is advisable to use a 90° or 45° elbow on
the suction line. This enables the pump to prime sooner and also
prevents kinking of the hose. In cases where a maximum volume of
water is required over a prolonged period, the suction line should

be led almost horizontally to the pump. Thread compound should
be used on all pipe joints and connections should be thoroughly
tightened. A strainer should be connected to the bottom end of
the suction pipe and it should be well submerged at all times.
c) WIRING: It is recommended that a separate circuit be used from
the distribution panel to the pump unit. A properly fused disconnect
switch is to be installed in the line, making sure that the correct
gauge of cable is used to carry the load. Very long leads will
require a larger cable. An electrician should be employed to do
the wiring.
WARNING:
DO NOT RUN THE PUMP BEFORE PRIMING
IT; THE SEAL AND IMPELLER COULD BE PERMANENTLY
DAMAGED.
a) PRIMING: Remove the priming plug located on the top of the
pump casing and fi ll the casing with water. Replace the priming
plug.
b) PRIMING UNDER PRESSURE (Figure 1): To prime under
pressure, place a check valve on the discharge line of the pump
and a petcock or a ball-type air bleeder in place of the priming plug,
or an air bleed line with a gate valve connected to the discharge
line. The liquid can then remain in the discharge pipe, allowing
the pump to draw the air bleeder, thereby facilitating priming.
c) STARTING THE PUMP: Never operate the pump dry as this may
damage the seal. If an exceptionally long suction line is used, the
pump casing may become overheated or vapor-locked. Should
this occur, replace the water in the casing with cold water and
continue priming.
d) DRAINING: Should the pump be subject to freezing temperatures,
it will be necessary to drain the pump completely. To drain, remove
the drain plug (10) located at the bottom of the front face of the
pump casing and the priming plug (11) and make sure that the
drain hole is not choked. After all the water has been drained,
operate the pump for a few seconds to ensure that the impeller
(4) is devoid of water. Make sure that the suction line is also
devoid of water.
