17. The pump motor must be wired for the proper voltage in accordance with the wiring diagram supplied with the motor.
Wiring the motor with the incorrect supply voltage will cause damage to the motor and void the warranty.
18. The wiring to the motor should be kept as short as possible and large enough NOT to cause an excessive voltage
drop. Use the wire size table as a guide in selecting minimum conductor size.
19. Install, ground and bond wire according to local or National Electrical Code requirements.
GROUNDING
20. Permanently ground motor. Use green terminal provided under motor canopy or access plate; use size and type wire
required by code. Connect motor ground terminal to electrical service ground. On cord connected circuits, check
for proper grounding.
BONDING - (for permanently wired pumps)
21. The National Electrical Code Article 680-22 requires that the motor be electrically bonded to appropriate
permanently installed pool or spa/hot tub structure by a solid copper conductor no smaller than No. 8 AWG. Bonding
wire should be connected from the accessible wire connector on the motor shell 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 feet of the inside
walls of a swimming pool, spa or hot tub. A grounding lug is provided on the exterior of the motor shell for this
purpose.
WARNING
(For cord and plug-connected units) Do not bury cord. Locate cord to minimize abuse from lawn mowers, hedge trimmers and other
equipment.
WARNING
(For cord and plug-connected units) To reduce the risk of electric shock, replaced damaged cord immediately.
WARNING
(For cord and plug-connected units) To reduce the risk of electric shock, do not use extension cord to connect unit to electric supply;
