MAINTENANCE
WARNING
!
DO NOT open the strainer pot if the pump fails to prime or if the pump has been operating
without water in the strainer pot. Pumps operated in these circumstances may experience
a build up of vapor pressure and may contain scalding hot water. Opening the pump may
cause serious personal injury. In order to avoid the possibility of personal injury, make
sure the suction and discharge valves are open and strainer pot temperature is cool to
touch, then open with extreme caution.
!
To prevent damage to the pump and filter and for proper operation of the system, clean
pump strainer and skimmer basket regularly.
Strainer Basket Cleaning
a) Turn off the power to the pump.
b) Turn the filter MPV to 'Recirculate' before shutting off any valves. This will keep the filter
flooded while servicing the pump, and there will be no need to bleed air from the filter
after servicing. Revert the MPV back to 'Filter' position after the pump lid is back on
and sealed. If the pump is installed below water level, close any shut off valves on the
suction and discharge lines.
c) Relieve pressure in the system.
d) Turn the quarter turn lock ring lid in counter - clockwise direction for Hydrostar and
Hydrosteel pumps and for CI pumps, handles must be screwed on for turning the lock ring
anti - clockwise for removal of lid.
e) Lift and remove the lock ring and lid set from the wet end of the pump.
f) Put the debris from the basket into the trash and rinse out the basket.
g) Replace the basket.
h) If the pump is located above the pool water level, fill the basket with water.
i) Clean the lid, lid O-ring, and sealing surface of the pump pot.
j) Replace the lid by placing the lock ring and the lid on the pot. Make sure the lid O-ring is
properly placed. Seat the lock ring and lid then turn clockwise until the lid is hand tight. Do
not use any tools to tighten the lid. For the Cast Iron Pump, turn the lock ring clockwise
until stop.
k) Open all valves on the suction and discharge lines.
l) If the pump is located below the water level of the pool, the pump will fill with water.
m) Stand clear of the filter. Turn on the power to the pump.
n) If the pump does not prime and all instructions to this point have been followed, check for
suction leaks and repeat steps (h) through (o).
CAUTION
Winterizing
If the air temperature drops below 0°C (35°F), the water in the system can freeze and cause
damage. Freezing damage is not warrantable.
To prevent freezing damage follow the procedures listed below:
a) Shut off electrical power for the pump at the house circuit breaker.
b) Drain the water out of the pump case by removing the two drain plugs from the case.
Store the plugs in the pump basket.
c) Cover the motor to protect it from severe rain, snow and ice.
d) If it is possible, store the pump in a dry location during this time.
e) Do not wrap the motor in plastic. It will cause condensation and rust on the inside of the
motor.
f) Where possible, have a qualified service technician or electrician disconnect the electrical
wiring at the switch or junction box and store the pump indoors.
g) When the pump is reactivated, ensure all seals and o-rings are in operational condition. If
they are not, re-greasing or replacing may be necessary.
!
In cold climate areas, when temporary freezing conditions may occur, run your filtering
equipment all night to prevent freezing.
