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 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 on page 11 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 removed of water, re-install the strainer cover and drain plugs. Store pump in a
dry area.
Shaft Seal Change Instructions
IMPORTANT SAFETY INSTRUCTIONS
PLEASE READ AND FOLLOW ALL INSTRUCTIONS
When servicing electrical equipment, basic safety precautions should always be observed including the following. Failure to follow
instructions may result in injury.
A.
WARNING – To reduce risk of injury, do not permit children to use this product.
B. Disconnect all electrical power service to pump before beginning shaft seal replacement.
C. Only qualified personnel should attempt rotary seal replacement. Contact your local authorized Hayward Dealer or
service center if you have any questions.
Exercise extreme care in handling both the rotating and the stationary sections of the two-part replacement seal. Foreign matter or
improper handling will easily scratch the graphite and ceramic sealing surfaces.
Removing the Motor Assembly (See Parts Diagram on page 11 of this manual for pump component locations.)
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).
