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
• Have an electrician provide electrical power to the motor.
• Motor must be grounded and terminal cover in place to reduce
electrical shock hazard.
• 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 of time,
the suction line should be led almost horizontally to the pump.
Thread compound should be used on all pipe joints and con-
nections 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.
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.

ImpEllER could BE pERmANENTlY dAmAGEd.
pRImING: Remove the priming plug located on the top of
the casing and fill the pump casing with water. Replace the
priming plug.
pRImING uNdER pRESSuRE: (Refer to Figure 1). Should it
be necessary to prime under pressure, place a check valve on
the discharge line of the pump and a pet cock 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. It will then be pos-
sible for the liquid to remain in the discharge pipe and allow the
pump to draw the air bleeder, thereby facilitating priming.
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 vapour
locked. Should this occur, replace the water in the casing with
cold water and continue priming.
dRAINING: Should the pump be subject to freezing tempera-
tures, 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, operating the pump for a few seconds will ensure that
the impeller (4) is devoid of water (make sure that the suction
line is also devoid of water).
