ELECTRICAL

Risk of electrical shock.
Plug pump into a

grounded, GFCI-protected 115
Volt circuit only. Incorrect
voltage can cause fire or seri-
ously damage motor and voids
warranty. Protect cord from
water and physical damage.

GFCI tripping indicates

an electrical problem. If

GFCI trips and will not reset,
have a qualified electrician in-
spect and repair electrical sys-
tem.

Risk of electrical

shock. Unplug motor before
servicing or repairing pump or
motor.

Wiring:

Install a Ground Fault Circuit Interrupter (GFCI) in cir-
cuit; it will sense a short-circuit to ground and discon-
nect power before it becomes dangerous to pool users.
For size of GFCI required and test procedures for GFCI,
see manufacturer’s instruction.
In case of power outage, check GFCI for tripping (which
will prevent normal water circulation). Reset if neces-
sary. 
Match circuit breaker size to Table III below.
• Do not modify cord, plug, or receptacle. If an existing

circuit must be used and the receptacle and plug do
not match exactly, consult a licensed electrician.

• Do not use an extension or drop cord with this system;

it could cause a fire hazard or low voltage problems.
Wet cords cause shock hazards. Extension cords can
easily become cut or frayed and dangerous when
placed across yard areas or walkways.

Voltage:

Voltage at motor must be not more than 10% above or
below motor nameplate rated voltage or motor may
overheat, causing overload tripping and reduced compo-
nent life. If voltage is less than 90% or more than 110%
of rated voltage when motor is running at full load, con-
sult power company.
