Storage / Winterization
WARNING
– Separation Hazard.
Do not purge the system with compressed air. Purging the system with
compressed air can cause components to explode, with risk of severe injury or death to anyone nearby. Use only a
low pressure (below 5 PSI), high volume blower when air purging the pump, filter, or piping.
ATTENTION
– Allowing the pump to freeze with water in it will void the warranty.
ATTENTION
– Use ONLY propylene glycol as antifreeze in your pool/spa system. Propylene glycol is non-
toxic and will not damage plastic system components; other anti-freezes are highly toxic and may damage plastic
components in the system.
Drain all water from pump and piping when expecting freezing temperatures or when storing pump for a long time
(see instructions below). Gravity drain system as far as possible.
Keep motor dry and covered during storage. To avoid condensation/corrosion problems, do NOT cover or wrap pump
with plastic film or bags.

Storing Pump For Winterization
WARNING
– To avoid dangerous or fatal electrical shock hazard, turn OFF power to motor before draining
pump. Failure to disconnect power may result in serious personal injury or death.
1.
Drain water level below all inlets to the pool.
2.
Remove drain plugs and strainer cover from strainer housing. (See “Parts Diagram” in section 10.1 of this
manual for pump component locations.)
3.
Disconnect pump from mounting pad, wiring (after power has been turned OFF), and piping.
4.
Once the pump is fully drained of water, re-install the strainer cover and drain plugs. Store pump in a dry area.

Removing the Motor Assembly
1.
Remove the six (6) 5/16" x 2" hex head bolts (item #17), which hold the motor assembly to the pump/strainer
housing (item #3), using a 1/2" wrench or socket.
2.
Slide the motor assembly out of the pump/strainer housing (item #3), exposing the diffuser (item #9). Remove
the two diffuser screws (item #7), and pull the diffuser (item #9) off of the seal plate (item #15) to expose the
impeller (item #12).
