Increase size of both suction and discharge piping at pump if any
appreciable run of pipe is required. Never use a smaller suction pipe than
the suction connection on the pump. To avoid putting excess strain on the
pump, use a pipe wrench to hold suction and discharge bosses of pump
while making up piping.
Keep suction pipe free from air leaks. Horizontal run of suction piping
must have a gradual upslope towards the pump. Avoid fittings which may
cause an air trap. Install a check valve in suction pipe to prevent loss of
pump prime.
Install a gate valve and union in discharge line. To remove pump for
service, close gate valve and disconnect union.
ELECTRICAL
Ground motor before connecting to electrical power supply!
Failure to ground motor can cause severe or fatal electrical shock
hazard!
Do not ground to a gas supply line!
To avoid dangerous or fatal electrical shock, turn OFF power to
motor before working on electrical connections.
Ground Fault Circuit Interrupter (GFCI) tripping indicates an
electrical problem. If GFCI trips and will not reset, have a qualified
electrician inspect and repair electrical system.
Exactly match supply voltage to nameplate voltage! Incorrect
voltage can cause fire or seriously damage motor and voids
warranty. If in doubt consult a licensed electrician.
Voltage:
Voltage at motor must be not more than 10% above or below motor
nameplate 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/Bonding:
Install, ground, bond and wire motor according to local and National
Electrical Code requirements.
Permanently ground motor. Use green ground terminal provided under
motor canopy or access plate (see Figure 2); use size and type wire
required by code. Connect motor ground terminal to electrical service
ground.
Bond motor to pool structure. Use a solid copper conductor, size No. 8
AWG (8.4 sq. mm) or larger. Run wire from external bonding lug (see
Figure 2) to reinforcing rod or mesh.
Connect a No. 8 AWG (8.4 sq. mm) solid copper bonding wire to the
pressure wire connector provided on the motor housing and to all metal
parts of the swimming pool, spa, or hot tub and to all electrical
equipment, metal piping or conduit within 5 feet (1.5 m) of the inside
walls of swimming pool, spa, or hot tub.
