Electrical (cont’d.)

 

 

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 – 

All electrical wiring MUST be in conformance with all applicable local codes, regulations, 

and the National Electric Code (NEC).

 

 

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.    

 

 
Start-Up & Operation 

 

Prior to Start-Up 

 

NOTE

 - If it is necessary to perform a pressure test, prior to initial use to ensure pump is functioning properly, then the 

following criteria should be maintained for this test: 

 

1.  Have a professional perform this test.   
2.  Ensure all pump and system components are sealed properly to prevent leaks.   
3.  Remove any trapped air in the system by fully opening filter manual air relief valve until a 

steady stream of water (not air or air and water mix) is discharged from the valve. 

4.  Allow no more than 50 psi (345 kPa) at a water temperature no higher than 100

°

 F (38

°

 C).   

5.  Run pressure test for no longer than 24 hours.  Immediately inspect all parts to verify they are 

intact and functioning properly.   

 

  WARNING –

 

If pump is being pressure tested (50 PSI MAXIMUM), be sure pressure 

has been relieved prior to removing cover.

  

 

 
 
 
 
 

  WARNING – 

All suction and discharge valves 

MUS

T be 

OPE

N, as well as filter air relief 

valve (if available) on filter, prior to starting the circulating pump system.  Failure to do so could result in 
severe personal injury.
