ELECTRICAL REQUIREMENTS
This section describes how to secure and wire the EQ Series
Electrical Requirements
Note: Do not install the pump motor within 5 ft (1.5 m) of the inside walls of the pool wall unless the pump bears
the UL listing mark. UL listed pumps may be installed within 5 ft (1.5 m) of the inside walls of a swimming pool,
spa or hot tub only if a solid copper bonding conductor not smaller than No. 8 AWG (No. 10 SWG) is connected
from a bonding lug wire connector on the motor to all metal parts of the swimming pool, spa or hot tub structure
and to all electrical equipment, metal conduit, and metal piping within 5 ft (1.5 m) of the inside walls of the
swimming pool, spa or hot tub.
To prevent possible voltage reduction that cause flicker sensations in lighting equipment, this product should be
powered by a dedicated power line. Other equipment connected to the same power line may experience operations
problems caused by the inrush current during start-up of this product.
This pump is for use with permanently installed pools and may also be used with hot tubs and spas if so marked.
Do not use with storable pools. A permanently installed pool is constructed in or on the ground or in a building such
that it cannot be readily disassembled for storage. A storable pool is constructed so that it may be readily disassembled for storage and
reassembled to its original integrity.
RISK OF ELECTRICAL SHOCK OR ELECTROCUTION.
This pool pump must be installed by a licensed or certified electrician or a qualified pool installer in accordance with
the 2008 National Electrical Code ("NEC") and/or all applicable local codes and ordinances. The specific section of
NEC covering your pump may vary depending on your location. Some states, and/or municipalities may not have
adopted the 2008 edition of the NEC. In this case your state or local code may only be applicable and/or an earlier
edition of the NEC may apply. Please check your local and state codes and regulations before commencing any
installation of this pump. Improper installation could create, among other things, an electrical hazard which may
result in death or serious injury to pool users, installers, or others due to electrical shock, and/or property damage. Always disconnect
power to the pool pump at the circuit breaker before servicing the pump. Failure to do so could result in death or serious injury to pool
users, installers or others (due to electrical shock) and/or property damage.
1. Ensure that the electrical service is disconnected, properly tagged and locked out before working on the
pump.
2. Carefully review the motor label. Take note of the important nameplate information such as volts, amps,
phase, HP and code. Most pump models may be field connected so that they can operate on two different
voltage circuits. Use extreme care in reviewing the motor wiring diagrams and always verify the voltage of the
electrical supply circuit.
3. Carefully review the electrical supply circuit to ensure that it is adequate to meet the pump requirements
identified on the motor nameplate. An electrical code letter is identified on the motor nameplate that identifies
the load characteristics of the motor.
Some single-phase pumps may contain an internal thermal protector designed to temporarily stop the pump if the
motor exceeds a preset temperature. The pump will automatically restart when the motor temperature falls to a
preset limit. Always disconnect power before working on the pump to eliminate the possibility that the pump could start unexpectedly.
Three-phase pumps do not contain an internal thermal protector and must be externally protected by an appropriately sized protective
device commonly referred to as a starter. Improper sizing of the starter can result in the motor being destroyed or in frequent tripping
of the starter.
4. It is important that all portions of the electrical circuit including the conductors that connect the electrical
panel to the pump motor are properly sized based on the nameplate information on the pump.
5. Following the National Electrical Code and any local electrical codes connect the grounding conductor
and electrical supply conductors to the motor. Ensure that the pump is properly grounded per the above
codes utilizing the grounding screw identified in the terminal box of the pump motor.
