Section 7. Maintenance
7.1 Routine Maintenance
Inspect the pump filter basket for debris by looking
through the clear pump lid. Remove any debris,
because as debris accumulates, it will begin to block
the flow of water through the pump. Keep the basket
clean to improve the performance of the pump.
1. Turn o the power to the pump. If the pump is located
below the water level, close the isolation valves on the
suction and discharge sides of the pump to prevent
backow of water.
2. Turn the locking ring counter-clockwise until ‘START’
aligns with the ports. Carefully remove the lid.
3. Lift the basket out of the pump.
4. Dispose of the debris and thoroughly clean the basket,
making sure all the holes are open. Using a garden
hose, spray the basket from the outside to help clear
the holes. Remove any remaining debris by hand.
5. Replace the basket in the pump by aligning the
opening with the suction pipe. If aligned properly, the
basket will drop easily into place. Do not force
it into place.
CAUTION
A misaligned basket will cause the lid to be
improperly seated, allowing an air leak, which could
result in pump damage.
6. Remove the lid seal and remove debris around the lid
seal seat, as this can allow air to leak into the system.
Clean the lid seal and place it on the lid.
7. Replace the lid with locking ring. Hand-tighten the
lid to make an air-tight seal. Do not use any tools to
tighten the lid: hand-tighten only.
8. Verify that all valves have been returned to the proper
position for normal operation.
9. Open the pressure release valve on the lter, and make
sure it is clean and ready for operation.
10. Turn on the power to the pump. Once all the air has
been evacuated from the lter, close the pressure
release valve.
7.2 Winterizing the Pump
CAUTION
The pump must be protected when freezing
temperatures are expected. Allowing the pump
to freeze will cause severe damage and void the
warranty.
CAUTION
Do not use antifreeze solutions in the pool,
spa, or hot tub systems! Antifreeze is highly toxic
and may damage the circulation system. The only
exception to this is Propylene Glycol. For more
information, see your local pool/spa supply store or
contact a qualified swimming pool service company.
1. Drain all water from the pump, system equipment, and
piping.
2. Remove the two (2) drain plugs. Store the drain plugs
in a safe location and reinstall them when the cold
weather season is over. Ensure the drain plugs and
o-rings are not misplaced.
3. Keep the motor covered and dry. Do not cover
the pump with plastic, because this will create
condensation that will damage the pump.
NOTE AstralPool recommends having a qualied service
technician or electrician properly disconnect the
electrical wiring at the switch or junction box. Once
the power is removed, loosen the two (2) unions
and store the pump indoors. For safety, and to
prevent entry of contaminants, reinstall all conduit
and terminal box covers.
4. When the system is reopened for operation, have a
qualied technician or electrician make sure all piping,
valves, wiring and equipment are in accordance with
the manufacturer’s recommendations. Pay close
attention to the lter and electrical connections.
5. The pump must be primed prior to starting. Refer to
Section 5.2, Starting Up the Pump.
