PACKAGE CONTENTS
1. The catalog lists all parts included with package.
2. Be sure all parts have been furnished and that nothing
has been damaged in shipment.
3. OPEN PACKAGES AND MAKE THIS CHECK BEFORE
GOING ON JOB.
PIPING - Pipes must line up and not be forced into position
by unions. Piping should be indepen dently supported near
the pump so that no strain will be placed on the pump
casing. Where any noise is objectionable, pump should be
insulated from the piping with rubber connections. Always
keep pipe size as large as possible and use a minimum of
fittings to reduce friction losses.
SUCTION PIPING - Suction pipe should be direct and as
short as possible. It should be at least one size larger
than suction inlet tapping and should have a minimum of
elbows and fittings. The piping should be laid out so that it
slopes upward to pump without dips or high points so that
air pockets are eliminated. The highest point in the suction
piping should be the pump inlet except where liquid flows
to the pump inlet under pressure. A foot valve must be used
to keep pump primed. Where liquid flows to the pump, it
may be desirable to use a check valve in the suction line or
discharge line to keep pump primed.
To prevent air from being drawn into suction pipe due to a
suction whirlpool, the foot valve should be submerged at
least three feet below the low water level. The suction pipe
must be tight and free of air leaks or pump will not operate
properly.

DISCHARGE PIPING - Discharge piping should never be
smaller than pump tapping and should preferably be one size
larger. A gate valve should always be installed in discharge
line for throttling if capacity is not correct. To protect the
pump from water hammer and to prevent backflow, a check
valve should be installed in the discharge line between the
pump and gate valve.
ELECTRICAL CONNECTIONS - Be sure motor wiring is
connected for voltage being used. Unit should be connected
to a separate circuit, direct from main switch. A fused
disconnect switch or circuit breaker must be used in this
circuit. Wire of sufficient size should be used to keep voltage
drop to a maximum of 5%. All motors, unless provided with
built-in overload protection, must be protected with an
overload switch, either manual or magnetic.
Never install a pump without proper overload protection.
When motor is mounted on a base plate or on slide rails
for adjustment, flexible metallic conduit should be used to
protect the motor leads.
PRIMING - The pump must be primed before start ing. The
pump casing and suction piping must be filled with water
before starting motor. Remove vent plug in top of casing
while pouring in priming water. A hand pump or ejector can
be used for priming when desired. When water is poured into
pump to prime, use care to remove all air before starting
motor.
If pump does not start immediately, stop and reprime.
STARTING - It is good practice to close the dis charge valve
when starting the pump as it puts less starting load on the
motor. When the pump is up to operating speed, open the
discharge valve to obtain desired capacity or pressure. Do
not allow the pump to run for long periods with the discharge
valve tightly closed. If the pump runs for an extended period
of time without liquid being discharged, the liquid in the
pump case can get extremely hot.
