Electrical
A Ground Fault Circuit Interrupter (GFCI)
is required in the circuit. For size of GFCI
required see manufacturer’s instructions.
• Never ground to a gas supply line.
• To avoid dangerous or fatal electrical
shock: turn OFF, disconnect the power
at its source, lock out power to motor,
and place a tag on the dedicated GFCI
circuit breaker indicating the power
is to remain OFF before working on
electrical connections.
Ground Fault Circuit Interrupter (GFCI) trip-
ping indicates an electrical problem. If GFCI
trips, determine the reason for tripping. If
you are uncertain, have a qualifi ed electri-
cian inspect and repair the electrical system.
Verify supply voltage matches the nameplate
voltage. Incorrect voltage can cause fi re or
seriously damage motor and voids warranty.
VOLTAGE
Voltage at motor must be within 10% of
the motor nameplate rated voltage or
motor may overheat, causing overload
tripping and reduced component life.
Verify voltage is correct before applying
power. If voltage does not fall within the
specifi ed range during operation consult
the power company.
The pumps are shipped with motors
wired for 208-230 volt operation. The
3/4, 1 and 1-1/2 HP models are equipped
with a voltage change device for
115/208-230 operation. Refer to the mo-
tor nameplate for 115 Volt hook-up.
GROUNDING/BONDING
Install, ground, bond and wire motor
according to local or National Electrical
Code requirements. Permanently ground
the motor. Use ground terminal provided
in the terminal box on the back of the
motor. Use size and type wire required
by local codes. Connect motor ground
terminal to electrical service ground.
Bond motor to pool structure. Use a
solid copper conductor, size No. 6 AWG
or larger. Run wire from external bond-
ing lug to reinforcing rod or mesh.
Use solid copper bonding conductor not
smaller than 6 AWG (13 mm
2 ) from the
accessible wire connector on the mo-
tor to all metal parts of the swimming
pool or spa structure and to all electrical
equipment, metal conduit, and metal
piping within 5 feet (1-1/2 m) of the in-
side walls of the swimming pool or spa.
WIRING
Follow all national and local wiring codes.
If unsure of code requirements consult a
professional electrician. Pump must be per-
manently connected to a dedicated circuit. If
unsure consult a licensed electrician.
NOTE: All electrical wiring and components
must be selected and installed in confor-
mance with the latest NEC requirements
and local codes. If you are unsure about the
requirements consult a licensed electrician
familiar with the requirements.
Operation
Do not run pump dry. Fill pump with
water before starting motor.
Before removing trap cover:
1. CLOSE GATE VALVES in suction and
discharge pipes
2. RELEASE ALL PRESSURE from pump
and piping system
If pump is being pressure tested, be
sure pressure has been released before
removing trap cover.
Do not block pump suction. To do so
with body may cause severe or fatal
injury. Small children using pool must
ALWAYS have close adult supervision.
Fire and burn hazard.
Motor runs at high
temperatures, to reduce the risk of fi re,
do not allow debris, or foreign matter
to collect around the pump motor.
Allow motor to cool prior to handling or
performing maintenance.
The motor is equipped with an internal
thermal protection circuit to guard against
overheating. The maximum ambient
temperature for motor operation must not
exceed rating on motor model plate.
PRIMING PUMP
Release all pressure from fi lter, pump,
and piping system; see the fi lter owner’s
manual. In a fl ooded suction system (water
source higher than pump), pump will prime
automatically when suction and discharge
valves are opened. If pump is located above
the normal pool water level remove ring
and cover assembly and slowly fi ll basket
and pump with water. Clean and inspect
o-ring; reinstall on trap. Replace ring and
cover assembly rotate clockwise to tighten
cover (see Figure 3).
Clamp ring must engage with pump body.
Push down and rotate until internal stops
are felt. Properly aligned tabs shown above
in Figure 3, assure lid is securely clamped.
Failure to tighten clamp ring as indicated
will reduce product strength, resulting in
failure of components, and bodily injury.
Pump prime time will
depend on vertical
distance and length of suction line. If pump
does not prime, make sure that all valves
are open, suction pipe is submerged. Verify
there are no leaks in suction lines. See
Troubleshooting Guide for further assistance.
Maintenance
All of our pumps are shipped from the fac-
tory with DANGER and/or WARNING labels
already on the pump. These labels contain
a series of basic, yet extremely important
safety messages for the user and bystander.
Regardless of how well these labels are
attached or how scratch resistant or wear-
resistant they may be, it is possible that, in
time, the wording may become illegible
with normal use. Whenever you are repair-
ing the pump, performing routine mainte-
nance, or have the opportunity to inspect
the pump, make sure the label is readable.
If the label is not legible, replace the label
with an adhesive version that is available at
no charge by calling 1-877-278-2797. The
unit must be connected only to a supply
circuit that is protected by a ground-fault
circuit-interrupter(GFCI). Such a GFCI should
be provided by the installer and should be
tested on a routine basis. To test the GFCI,
push the test button. The GFCI should inter-
rupt power. Push the reset button. Power
should be restored. If the GFCI fails to
operate in this manner, the GFCI is defective.
If the GFCI interrupts power to the pump
without the test button being pushed, a
ground current is fl owing, indicating the
possibility of an electric shock. Do not use
this pump. Disconnect the pump and have
the problem corrected by a qualifi ed service
representative before using.
Use only parts supplied by manufacturer.
Similar looking parts may not have suffi cient
strength for safe operation.
The only routine maintenance needed is in-
spection/cleaning of strainer basket. Debris
or trash that collects in basket will choke off
water fl ow through the pump.
Before attempting to clean basket:
A. Stop pump, disconnect power at its
source, lock out power, place tag on the
dedicated GFCI circuit breaker indicating
the power is to remain OFF, close valves
in suction and discharge, and release
pressure from system.
