WARNING
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE CIRCULATING
SYSTEM (e.g., LOCK RING, PUMP, FILTER, VALVES, ETC.) IS SERVICED, AIR CAN ENTER
THE SYSTEM AND BECOME PRESSURIZED. PRESSURIZED AIR CAN CAUSE THE LID TO
BLOW OFF WHICH CAN RESULT IN SEVERE INJURY, DEATH, OR PROPERTY DAMAGE. TO
AVOID THIS POTENTIAL HAZARD, FOLLOW THESE INSTRUCTIONS.
10. Open the High Flow™ manual air relief valve on top of the filter.
11. Stand clear of the filter. Start the pump.
12. Bleed air from the filter until a steady stream of water comes out.
Clamp
Lid
Close the High Flow™ manual air relief valve.
B. Winterizing.
1. If the air temperature drops below 35° F. the water in the pump can
freeze and cause damage. Freeze damage is not warrantable.
2. To prevent freeze damage follow the procedures listed below.
Volute
a. Shut off electrical power for the pump at the house circuit breaker.

Figure 3.
twist drain plugs from the case. Store the plugs in the pump
basket.
c. Cover the motor to protect it from severe rain, snow and ice.
d. Do not wrap the motor in plastic. It will cause condensation and rust on the inside of the motor.
C. Care of Electric Motor.
1. Protect from heat.
a. Shade the motor from the sun.
b. Any enclosure must be well ventilated to prevent overheating.
c. Provide ample cross ventilation.
2. Protect against dirt.

SECTION III. SERVICE.
WARNING
Risk of electrical shock or electrocution.
This pool pump must be installed by a licensed or certified electrician or a qualified pool serviceman in
accordance with the National Electrical Code and 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 also 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.
Read all servicing instructions before working on the pump.
A. Pump Disassembly.
1. All moving parts are located in the rear sub-assembly of this pump.
Toolsrequired:
a. 3/32 inch Allen head wrench.
b. ½ inch open end wrench.
c. 9/16 inch open end wrench.
d. Flatbladescrewdriver.
2. To remove and repair the motor sub-assembly perform the following procedures.
a. Turn off the pump circuit breaker at the main panel.
b. Drain the pump by removing the drain plugs.
c. Remove the 6 bolts that hold the main pump body (strainer pot/volute) to the rear sub-assembly.
d. GENTLY pull the two pump halves apart, removing the rear sub-assembly.
e. Use a 3/32 inch Allen head wrench to loosen the two holding screws located on the diffuser.
CAUTION
Be sure not to scratch or mar the polished shaft seal faces; seal will leak if faces are damaged.
f. Hold the impeller securely in place and remove the impeller lock screw by using a flat blade
screwdriver. The screw is a left-handed thread and loosens in a clockwise direction.
g. Remove the shaft cap located at the back of the motor and hold the shaft secure with a ½ inch
(Century) or 7/16 inch (Franklin) open-end wrench. On A. 0. Smith motors, remove the motor
canopy, move the capacitor to one side and hold the shaft with a 7/16 inch open-end wrench.
h. To unscrew the impeller from the shaft, twist the impeller counterclock- wise.
i. Remove the four bolts from the seal plate to the motor, using a 9/16 inch wrench.
j. Place the seal plate face down on a flat surface and tap out the carbon/spring seat.
k. Clean the seal plate, seal housing, and the motor shaft.

B. Pump Reassembly/Seal Replacement; see Section V, Technical
Data, Figure 4.
Bolt
1. When installing the replacement shaft seal, use silicone
sealant on the metal portion, before pressing into the seal
plate.
2. Before installing the ceramic section of the seal into the
impeller, be sure the impeller is clean. Use a light density
soap and water to seal the seal. Press the seal into the
impeller with your thumbs and wipe off the ceramic and
carbon faces with a clean cloth.

3. Remount the seal plate to the motor.
4. Grease the motor shaft thread and screw impeller onto the
motor shaft.
Figure 4.
5. Screw in the impeller lock screw (counter-clockwise to tighten).
6. Remount the diffuser onto the seal plate. Make sure the plastic pins and holding screw inserts are
aligned.
7. Grease the diffuser O-ring and seal plate gasket or O-ring prior to reassembly.
8. Grease the bolt threads, assemble the motor sub-assembly to the strainer pot-pump body by using the
two through bolts for proper alignment. Do not tighten the through bolts until all 6 bolts are in place and
finger tightened.
9. Fill the pump with water.
10. Reinstall the pump lid and plastic clamp; see SECTION II. START-UP.
11. Reprime the system.
C. The Shaft Seal.
1. The Shaft Seal consists primarily of two parts, a rotating member and a ceramic seal.
2. The pump requires little or no service other than reasonable care, however, a Shaft Seal may
occasionally become damaged and must be replaced.
CAUTION
The polished and lapped faces of the seal could be damaged if not handled with care.
CAUTION
In mild climate area, when temporary freezing conditions may occur, run your filtering equipment all night to prevent
freezing.
SECTION IV. RESTARTINSTRUCTIONS.
A. If pump is installed below the water level of the pool, close return and suction lines prior to opening hair and
lint pot on pump. Make sure to re-open valves prior to operating.
CAUTION
DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump will start leaking. If this
occurs, the damaged seal must be replaced. ALWAYS maintain proper water level in your pool (half way up skimmer opening). If
the water level falls below the skimmer opening, the pump will draw air through the skimmer, losing the prime and causing the
pump to run dry, resulting in a damaged seal.
Note
Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and seal.

B. Priming the Pump.
1. The pump strainer pot must be filled with water before the pump is initially started. Follow these steps to
prime the pump.
a. Remove the pump lid plastic clamp. Remove the pump lid.
b. Fill the pump strainer pot with water.
c. Reassemble the pump cover and plastic clamp onto the strainer pot. The pump is now ready to
prime.
d. Open the air release valve on the filter, and stand clear of the filter.
e. Turn on the switch or time clock.
f. When water comes out of the air release valve, close the valve. The system should now be free of air
and recirculating water to and from the pool.
2. For 2-speed pumps:
a. Pump should run on high-speed for priming.
b. The pump should not run longer than 8 minutes before priming is achieved.
SECTION V. TROUBLESHOOTING.
A. Failure to Pump.
1. Pump will not prime - too much air. - Remedy:
a. Check suction piping and valve glands on any suction gate valves.
b. Secure lid on pump strainer pot and make sure lid gasket is in place.
c. Check water level to make sure skimmer is not drawing air.
2. Pump will not prime--not enough water. - Remedy:
a. Make sure suction lines, pump strainer, and pump volute are full of water.
b. Make sure valve on suction line is working and open, (some systems do not have valves).
c. Check water level to make sure water is available through skimmer.
3. Pump strainer clogged. - Remedy:
a. Clean pump strainer pot.
4. Pump strainer gasket defective. - Remedy:
a. Replace gasket.
B. Reduced Capacity and/or Head.
1. Air pockets or leaks in suction line. - Remedy:
a. See item A.1. of this section, above.
2. Clogged impeller. Remedy:
a. Turn off electrical power to the pump.
b. Remove the clamp that holds the volute to the seal plate.
c. Slide the motor and seal plate away from the volute.
d. Clean debris from impeller. If debris cannot be removed, complete the following steps.
(1) Remove left hand thread anti-spin bolt and O-ring.
(2) Remove, clean and reinstall impeller.
(3) Reinstall anti-spin bolt and O-ring.
e. Reinstall wear-ring, diffuser, and O-ring.
