8. SAVETHESEINSTRUCTIONS.
SECTIONII. HOWYOURFILTERWORKS
Your cartridge filter is designed to produce clear, sparkling water and operate for years with a minimum of
maintenance when installed, operated and maintained in accordance with these instructions.
Your filter uses a cartridge element to remove dirt particles from the water. Dirt is collected in the filter by
the cartridge element as water flows through the filter. Water enters the filter through the filter inlet port
and is distributed evenly through the cartridge element. The dirt is removed by the cartridge fabric and the
clean water flows through the filter outlet port and is returned to the pool through the piping or hoses.
After a period of time, dirt will accumulate in the filter causing a resistance to the flow of water through the
filter. This resistance results in a diminished flow of water and a rise in the filter pressure. Eventually the
filter will have removed so much dirt and the filter pressure risen to such a point that it will be necessary to
cleanyourfilter,seeSECTIONVI.CLEANINGFILTER.
The filter’s function is to remove suspended matter from the water and does not sanitize the water. For
sparkling clear water, the water must be sanitized as well as balanced. Pool chemistry is a specialized area,
and you should consult your local pool service specialist for specific details. In general, proper pool
sanitation requires a free chlorine level of 1 to 2 PPM and a PH range of 7.2 to 7.6.
WARNING
To reduce the risk of electrical shock, Only connect to a GFCI protected receptacle. Failure to
do so could result in an electrical shock to pool users, installers, or others which can result in
seriouspersonalinjury or death.

2. TOCLEANBASKET-(pumpmustbeoff)
Follow the instructions above to prime the pump. After removing the lid, remove the basket and
empty the debris. Replace the basket and proceed to fill the pot with water. It is important to visually
inspect the basket, through the see through lid, at least once a week. A dirty basket will reduce the
efficiency of your system, and can put an abnormal load on the pump which could result in costly
repairbills.
WARNING
Toreduce the risk ofelectrical shock, only connectto a GFCI protectedreceptacle. Failure to do
socould result in anelectrical shock to poolusers, installers, or otherswhich can result in
seriouspersonalinjury or death.

3. SHAFT SEAL - (rotary seal). The shaft seal consists of two parts:
a. Rotating ceramic seal, press fitted into the impeller.
b. A stationary spring loaded seal, press fitted into the rear of the volute.
4. THEELECTRICMOTOR.
a. The electric motor should be protected from foreign matter, water splashing, hosing, and the
weather. Enclosures should be well ventilated to prevent overheating. If a motor becomes
wet, permit it to dry before running it. If a motor has been damaged by water or dirt, the
warranty is void.
b. The motors used on these pumps are 48 frame through bolt motors. The through bolts are
used to secure the volute to the motor. When replacing the motor, mark the end bells and the
motor shell to indicate alignment. Remove the four nuts from the through bolts at the shaft
end. Place the shaft through the back of the volute and locate the bolts in line with the brass
inserts located in the four legs at the rear of the volute. Be sure the end bell and the shell
marking line up. Securely fasten the motor to the volute.
c. Protectthe motorfromheat. Provide ampleventilation.
CAUTION
The highly polished and lapped faces of the seal are easily damaged. Handle with care.
This centrifugal pump requires little or no service, however the shaft seal will wear with normal use
over the years and will require periodic replacement.
ALWAYS MAINTAIN PROPER WATER LEVEL IN THE POOL. Water level must be half way up the skimmer
opening.A low water levelcan cause the pumpmotor to run drywhich will damage themechanical seal and
causeexternal leakage.
CAUTION
CAUTION
DONOT RUN PUMP DRY. If the pump isrun dry, the mechanical seal will be damagedand external
leakagewill occur. When aseal is damaged, theseal must be replaced.
