Max-Flo™ PUMP Series
IS2800X5 Rev. C
Insure that the electrical supply available agrees with the motor’s voltage, phase, and cycle, and that the wire size is adequate
for the HP (kW) rating and distance from the power source.
NOTE - All electrical wiring MUST be performed by a
licensed electrician, and MUST conform to local codes and NEC regulations.
Use copper conductors only.

Voltage
Voltage at motor
MUST NOT
be more than 10% above or below motor name plate rated voltage, or motor may overheat,
causing overload tripping and reduced component life. If voltage is less than 90% or more than 110% of rated voltage when
motor is running at full load, consult Power Company.
Grounding And Bonding
Install, ground, bond, and wire motor in accordance with local or national electrical code requirements.
Permanently ground motor. Use green ground terminal provided under motor canopy or access place; use size and type wire
required by code. Connect motor ground terminal to electrical service ground.
Bond motor to pool structure. Bonding will connect all metal parts within and around the pool with a continuous wire.
Bonding reduces the risk of a current passing between bonded metal objects, which could potentially cause electrical shock if
grounded or shorted.
Reference NEC codes for all wiring standards including, but not limited to, grounding, bonding
and general wiring procedures.
Use a solid copper conductor, size 8 or larger. Run wire from external bonding lug to reinforcing rod or mesh. Connect a
No. 8 AWG (8.4 mm
2
) solid copper bonding wire to the pressure wire connector provided on the motor housing and to all
metal parts of swimming pool, spa, or hot tub, and to all electrical equipment, metal piping (except gas piping), and conduit
within 5 ft. (1.5 m) of inside walls of swimming pool, spa, or hot tub.
Wiring
WARNING –
A licensed electrician must do all wiring.
Pump MUST be permanently connected to circuit. If other lights or appliances are also on the same circuit, be sure to add
their amp loads before calculating wire and circuit breaker sizes. 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. Pump MUST be permanently connected to GFCI. In case of a power outage, check GFCI for tripping, which
will prevent normal pump operation. Reset if necessary.
