SECTION 1 EQUIPMENT OPERATION AND MAINTENANCE - Continued
1/3 MAINTENANCE - continued
Place a screwdriver, allen wrench or appropriate tool in the
end of the motor shaft and turn it clockwise. OR Remove
the fan cover and turn the fan in a clockwise direction
manually. This may require removal of the cover at the rear
of the motor or small circular cap at the rear center of the
motor.
To Replace the Mechanical Seal
To replace the mechanical seal, remove the eight (8)
screws holding the casing to the flange. Slide the motor
part including the seal housing out. Remove impeller by
turning it counter-clockwise when facing it, while holding
the motor shaft with a wrench or screwdriver at rear end
of motor. Pull the impeller from the motor shaft noting the
position of the seal. Remove the seal from the impeller
shaft. To re-assemble, reverse the process. Use only water
as a lubricant to install both sides of the seal. NO NOT use
grease or lube to install seal. It will damage the seal and
cause failure. Make sure both sides of the seal (ceramic and
spring portion) are clean. Gently wipe polished faces with
soft and dry cotton cloth. Surfaces can easily be damaged
by dirt and scratching. (Use a drop of loc-tite to secure the
impeller nut.)
1/4 WINTERIZING
CAUTION: The pump must be protected when freezing
temperatures are expected.
SECTION 2 TROUBLESHOOTING GUIDE
PROBLEM
1. Pump will not prime.
2. Motor does not turn.
POSSIBLE CAUSES
a. Suction air leak.
b. No water in pump.
c. Closed valves or blocked lines.
d. Low voltage to motor.
a. No power to motor.
b. Pump jammed.
1/4 WINTERIZING - continued
CAUTION: Allowing the pump to freeze will cause severe
damage and void the warranty.
There are two options when winterizing the pump:
Option 1:
Drain all the water from the pump, system equipment, and
piping. Remove drain plugs. DO NOT replace plugs. Store
the plugs in the empty strainer basket for winter. Keep the
motor covered and dry.
Option 2:
Drain all the water from the pump, system equipment, and
piping. Remove the pump and motor from the plumbing and
store indoors in a warm and dry location.
NOTE: When the winter season is over the pump will need
to be check and primed prior to start.
CAUTION: DO NOT run the pump dry. If the pump is run
dry, the mechanical seal will be damaged and the pump
will start to leak at the seal. If this occurs, the mechanical
seal will need to be replaced. ALWAYS maintain the proper
water level in your pool. Continued operation in this manner
could cause a loss of pressure, resulting in damage to the
pump casing, impeller, and mechanical seal.
Make sure the see-through lid and o-ring are clean
and properly positioned. Hand tighten see-through lid.
Tighten all pipes and fittings on suction side of the
pump. Be sure water in the pool is high enough to flow
through skimmer.
Make sure strainer tank is full of water.
Open all valves in system. Clean skimmer and strainer
tank. Open pump and check for clogging of impeller.
Check voltage at motor. If low, pump will not come up
to speed.
Check that all power switches are on. Be sure fuse or
circuit breaker is properly set. Time set properly? Check
motor wiring at terminals.
With power o , turn shaft. It should spin freely. If not,
disassemble and repair.
