WIRING
3 Phase Wiring - Wire a Single Speed, Single Voltage, 3
Phase Motor.
NOTICE: 3 phase models require magnetic motor starters
and external overload protection. If in doubt about the
procedure, consult a licensed electrician. There are three
terminals labeled L1, L2, and L3 (or LINE A, LINE B, and
LINE C) on the Max-E-Pro
Spa Pump motor. Attach the power leads to these
terminals as specified on the pump motor wiring label.
Check for proper pump motor rotation. If motor is not
running properly, switch any two of the three input wires.
Verify proper pump motor rotation.
NOTE: For 575 VAC models, consult a licensed
electrician.
Pump must be permanently connected to circuit. See
Figures 4A and 4B for wiring connection diagrams. If
other lights or appliances are also on the same circuit,
be sure to add their amp loads to pump amp load. (If
unsure how to do this or if this is confusing, consult a
licensed electrician.) Use the load circuit breaker as the
master on-off switch.
Install a Ground Fault Circuit Interrupter (GFCI) in
circuit; it will sense a short-circuit to ground and
disconnect power before it becomes dangerous to pool
users. For size of GFCI required and test procedures
for GFCI, see manufacturer's instructions.
In case of power outage, check GFCI for tripping
(which will prevent normal water circulation). Reset if
necessary.
NOTICE: If you do not use conduit when wiring motor,
be sure to seal wire opening on end of motor to prevent
dirt, bugs, etc., from entering motor.
Risk of dangerous or fatal electrical shock.
Be sure that power to the motor circuit is off before
working on wiring, wiring connections, or motor. Re-
install the motor end cover and all other wiring covers
before turning on the power.

1. Turn off power.
2. Remove the motor end cover.
To Wire a Single Speed, Single Voltage Motor
There are two terminals labeled L1 and L2. Attach the
power leads to these terminals. Either wire may attach to
either terminal.
To Wire a Dual-Voltage Motor
Dual voltage motors have a plug to change from 230 volts
(factory setting) to 115 volts).
1. If you have 230 volts motor supply voltage, confirm that
the plug is set for 230 volts. The arrow on the plug will
point to the 230 volt position. Note that plug only
connects with one prong in this position.
2. If you have 115 volt supply, pull the plug straight up and
place it on the two brass prongs as shown.
NOTE: Arrow is highlighted for clarity.
