WIRING AND GROUNDING
Install, ground and wire ac-
cording to local and National
Electrical Code requirements.
Install an all leg electrical power
disconnect switch near the
pump.
Disconnect electrical power
before installing or servicing
pump.
Electrical supply MUST match pump’s name-
plate specification. Incorrect voltage can cause
fire or damage to the motor and voids war-
ranty.
Motors without built-in protection MUST be
provided with contactors and thermal over-
loads for single phase motors, or starters with
heaters for three phase motors. See motor
nameplate.
•
Follow motor manufacturer’s wiring diagram on the
motor nameplate or terminal cover carefully.
•
Use only copper wire to motor and ground. The
ground wire MUST be at least as large as the wire to
the motor. Wires should be color coded for ease of
maintenance.

•
Three phase unit rotation may be checked by removing
motor end cap or plug and observing rotation of motor
shaft. To reverse rotation, reverse any two of the three
motor leads.
OPERATION
OPERATION WITHOUT PRIME, OR
AGAINST A CLOSED DISCHARGE
VALVE, CAN GENERATE HOT WA-
TER OR STEAM CAUSING INJURY
OR PROPERTY DAMAGE.
NOTICE: DO NOT OPERATE PUMP
WITHOUT PRIME OR
SEAL DAMAGE WILL
RESULT.
•
Prime pump by filling pump and piping through open-
ing in top of tee with clean water. See Figure 1.
•
Install pipe plug in top of tee using Teflon™ tape or
equivalent.
NOTICE: IF PUMP IS DRAINED OR SHUT OFF
DURING PRIMING PERIOD, CASING
MUST BE REFILLED BEFORE RESTART-
ING PUMP.
•
Start the pump and partially open discharge valve and
wait for system pressure to stabilize. If system pressure
is surging, or prolonged pressure drop is experienced,
the system may not be completely primed.
MAINTENANCE
FAILURE TO DISCONNECT ELEC-
TRICAL POWER BEFORE ATTEMPT-
ING ANY MAINTENANCE CAN
CAUSE SHOCK, BURNS OR DEATH.
•
No lubrication is required on pump.
For motor lubrication, refer to and
follow manufacturer’s instructions.
SEASONAL SERVICE
•
To REMOVE pump from service, remove all drain
plugs and drain all piping.
•
To RETURN pump to service, replace all drain plugs
using Teflon™ tape or equivalent.
•
Reconnect suction line if removed, examine union and
repair if necessary.
•
Reprime and operate pump following all instructions
and warnings in the “OPERATION” section of manu-
al.
