8.1. 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.

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.
WARNING – To reduce risk of injury, do not permit children to use this product.
Disconnect all electrical power service to pump before beginning shaft seal replacement.
Only qualified personnel should attempt rotary seal replacement. Contact your local authorized Leslie’s Dealer or service
center if you have any questions.
Refer to Figure 10.1-1 for pump component locations.
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.
9.1. Removing the Motor Assembly
1. Remove the four (4) 5/16" x 1.75" hex head bolts, which hold the motor assembly to the pump/strainer housing, using
a 1/2" wrench or socket.
2. Slide the motor assembly out of the pump/strainer housing, exposing the diffuser. Remove the three (3) diffuser screws
and pull the diffuser off of the seal plate to expose the impeller.
9.2. Removing the Impeller
3. To prevent the motor shaft from turning, secure using a 5/16” hex wrench on the motor shaft through the fan shroud
on the back of the pump.
4. Remove the impeller by rotating counterclockwise.
9.3. Removing the Ceramic Seat
5. Remove the spring seal assembly and seal plate from the motor by removing the four (4) 3/8” x 1” bolts that secure it
to the motor, using a 9/16” wrench or socket.
6. Press the ceramic seat with rubber cup out of the seal plate. If tight, use a small screwdriver to tap seal out.
STOP - Clean all recesses & parts to be reassembled. Inspect gaskets & replace if necessary.
9.4. Seal Installation
7. Clean and lightly lubricate the motor shaft and seal recesses in the seal plate with a dilute solution of non-granulated
liquid-type soap. Gently wipe the polished face of the ceramic seal with a soft cotton cloth. Lubricate the rubber cup
on the ceramic seat and press it firmly into the recess of the seal plate, with the polished ceramic surface facing out.
8. Reassemble the motor to the seal plate using the four (4) 3/8” x 1” bolts. Torque the bolts to 100 in-lbs.
9. Gently wipe the black, polished surface of the spring seal assembly with a soft cotton cloth.
10. Press the spring seal assembly onto the motor shaft, with the black polished surface facing the ceramic seat.
