MaxFlo VS Pump
IS2303VSP2 Rev-B
4.5.
Electrical
WARNING
– All electrical wiring MUST conform to local codes, regulations, and the National Electric Code
(NEC).
WARNING
– Ground and bond pump before connecting to electrical power supply. Failure to ground and
bond pump can cause serious or fatal electrical shock hazard. Do NOT ground to a gas supply line. To avoid
dangerous or fatal electrical shock, turn OFF power to pump before working on electrical connections. Fire Hazard -
match supply voltage to pump nameplate voltage. Insure that the electrical supply available agrees with the pump’s
voltage, phase, and cycle, and that the wire size is adequate for the amps rating and distance from the power
source. Use copper conductors only.

Electrical Specs
1.
Voltage: 230VAC, 60Hz, Single Phase
2.
Amps: 0.4 - 10.0
3.
Speed Range: 600-3450 rpm
Use copper conductors only. For indoor & outdoor use. Connect pump to a 15 amp branch circuit in accordance with
local codes, regulations, and the National Electric Code (NEC). A disconnecting means located at least 5 ft. from the
inside wall of the pool, spa, or hot tub must be provided.
4.7.
Voltage
Voltage at pump MUST NOT be more than 10% above or below nameplate rated voltage, or components may
overheat, causing overload tripping and reduced component life. If voltage is less than 90% (207 VAC) or more than
110% (253 VAC) of rated voltage (230 VAC) when pump is running at full load, consult the power company.
4.8.
Grounding and Bonding
1.
Install, ground, bond, and wire pump in accordance with local or national electrical code requirements.
2.
Permanently ground pump. Use green ground terminal provided under access plate; use size and type wire
required by code. Connect ground terminal to electrical service ground.
3.
Bond pump 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.
4.
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
) [No. 6 AWG (13.3 mm
2
) for Canada] 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.
4.9.
Wiring
WARNING
– All electrical wiring MUST conform to local codes, regulations, and National Electric Code (NEC)
1.
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 circuit breaker as the
master On-Off switch.
2.
If the MaxFlo VS pump is being used to replace an existing pump that was controlled by a separate mechanical
time clock, the MaxFlo VS pump should be connected directly to the line power supply, bypassing the time
clock. The time clock can then be used to power other equipment (such as a heater, heat pump, or booster
pump) that requires the filter pump to be operating when used. If the time clock is used in this manner, it
should be set to power the equipment during a time cycle when the MaxFlo VS pump is operating at an
appropriate flow rate to operate the other equipment, as defined by the timers set in the Timer Menu. See
section 6.7
