Motor Removal
RISK OF ELECTRICAL SHOCK OR ELECTROCUTION.
This pool pump must be installed by a licensed or certified electrician or a qualified pool installer in accordance with the National
Electrical Code (“NEC”) and/or all applicable local codes and ordinances. Improper installation will create an electrical hazard
which could result in death or serious injury to pool users, installers, or others due to electrical shock, and may cause damage
to property.
Always disconnect power to the pool pump at the circuit breaker before servicing the pump. Failure to do so could result in
death or serious injury to serviceman, pool users or others due to electric shock.
DO NOT open the strainer pot if pump fails to prime or if 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 strainer pot may cause serious personal injury. In order to avoid personal injury make sure the strainer pot temperature has cooled to room
temperature. Carefully remove the drain plug on the strainer pot and allow the pressure to equalize before removing the locking ring.
DO NOT OPERATE THIS UNIT DRY. Operating this unit dry will damage the shaft seal which will cause the pump will leak.
Motor must be wired as indicated on motor diagram (see box cover and motor nameplate). Refer to “Motor Rotation Check” for
correct pump rotation. Incorrect rotation can damage the pump.
Three Phase Motors are NOT thermally protected. Three Phase Motors MUST be installed in conjunction with a Magnetic Started equipped
with Thermal Overload Protection.
1. Support motor on both sides. Remove four hex head cap screws (22) that hold motor to volute (7).
2. Carefully and slowly pull motor (23) until seal flange (17) and impeller (15) are completely out of the volute (7). Avoid
resting entire unit on seal flange and impeller.
3. Remove Allen head cap screw (12) and washer (13) from center of impeller (15). Pull impeller from shaft. Do not lose
square key (21).
4. Remove seal spring member (16) from shaft. Avoid cutting rubber parts or scratching carbon face.
5. Remove two hex head cap screws (19) from seal flange (17). Hold seal flange so that it does not drop on motor shaft
while removing screws. Remove seal flange.
6. Remove ceramic seal face member (16) from center of seal flange (17) and o-ring (18) from groove. Check for nicks and
cuts. Replace as necessary.
7. Finally, remove water slinger (20) if replacing with new one or servicing motor.
Motor Installation
1. Slip water flange (20) on motor shaft past shoulder.
2. Press ceramic seal face member (16) into center cavity of seal flange (17) with the smooth ceramic facing out. Clean and
grease O-ring (18) and place in seal flange groove.
Note:
Make sure that the ceramic face is free from oil or grease.
3. Install seal flange on motor register and secure in place with two cap screws (19).
4. Press seal spring member (16) on motor shaft with carbon face towards ceramic seal member. Avoid cutting rubber parts
on shaft.
5. Line up keyways and push impeller (15) on motor shaft up
to shoulder. Insert square key (21) in place.
6. Secure impeller with washer (13) and impeller lock screw
(12).
7. Position and carefully install assembled motor to the volute
(7) and secure motor using cap screws (22).
8. Remove motor shaft and cap.
9. Momentarily start and stop motor. While impeller is still
turning, check the end shaft rotation. Rotation must be in
the direction indicated by the arrow on the outside of the
volute (7).
10. Fill Strainer pot with water, install basket and secure cover.
Pump is now ready for operation. Press in motor shaft
end cap.
