Electrical Installation
When installing and using the motor, basic safety precautions should always be followed. The wiring of
the motor should be done by a licensed electrician in accordance with local codes.
BONDING AND GROUNDING
1. The motor frame must be grounded to a reliable grounding point using a solid copper conductor,
No. 8 AWG or larger. In Canada, No. 6 AWG or larger must be used. If the pump is installed within five
(5) feet of the inside walls of the swimming pool, spa, or hot tub, the motor frame must be bonded to
all metal parts of the swimming pool, spa, or hot tub structure and to all electrical equipment, metal
conduit, and metal piping within five (5) feet of the inside walls of the swimming pool, spa, or hot tub.
2. Bond the motor using the provided external lug.
WARNING: Always disconnect the power source before working on a motor or its connected
load.
WARNING: In order to avoid the risk of property damage, severe personal injury, and/or death,
make sure that the control switch, time clock, or control system is installed in an accessible
location, so that in the event of an equipment failure or loose plumbing fitting, the equipment
can be easily turned off.
CAUTION: The pump must be permanently connected to a dedicated electrical circuit. No
other equipment, lights, appliances, or outlets may be connected to the pump circuit, with the
exception of devices that may be required to operate simultaneously with the pump, such as a
chlorinating device or heater.
WARNING: Motor fitted with internal auto reset. May restart without warning!
Electrical Wiring
1. The pump motor must be securely grounded using the #10 green headed ground screw provided
inside the motor terminal box.
NOTE: Do not connect to electric power supply until unit is permanently grounded.
2. Wire size must be adequate to minimize voltage drop during the start-up and operation of the pump.
See Table 1 for recommended wiring sizes.
3. Insulate all connections carefully to prevent grounding or short-circuits. Sharp edges on terminals
require extra protection. To prevent the wire nuts from loosening, tape them using suitable, listed (UL,
ETL, CSA) electrical insulating tape. For safety, and to prevent entry of contaminants, reinstall all
conduit and terminal box covers. Do not force connections into the conduit box.
