1/3 MAINTENANCE
The pump requires little or no service other than reasonable
care and periodic cleaning of the strainer basket. DO NOT
strike basket to clean. When cleaning the basket inspect
the lid o-ring for damage and replace if necessary.
NOTE: It is normal for a few drops of water to escape from
the mechanical seal from time to time. This is especially
true during the break-in period.
The mechanical seal may come worn and/or loose during
the course of time, depending on the running time and water
quality. If water continually leaks out, a new mechanical
seal should be fitted. After long periods of NOT operational
(seasonal storage, etc.), the pump must be checked for
ease of rotation while it is switched off.
WARNING: Before servicing the pump, switch off the
circuit breakers at the power source. Severe personal
injury or death may occur if the pump starts while your
hand is inside the pump.
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 sixteen (16)
bolts holding the casing to the seal housing. Slide the
motor part including the seal housing out. Remove the
terminal cover from the rear of the motor and secure the
center motor shaft with a 1/2" wrench. Remove impeller
nut by turning it counter-clockwise when facing it. 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. 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. 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 plug(s). DO NOT replace plug(s).
Store plug(s) in the 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.
