P/N 99226200 2 REV.C4-3-12WARNING
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 serious
personal injuryor death.

SECTION II. HOW YOUR FILTER WORKS
Your cellular media filter is designed to produce clear, sparkling water and operate for years with a mini-
mum of maintenance when installed, operated and maintained in accordance with these instructions.
Your filter uses a cellular media cartridge element to remove dirt particles from the water. Dirt is collected
in the filter bythe cellular media element as water flows through the filter. Water enters the filter through
the filter inlet port and is distributed evenly through the cellular media element. The dirt is removed by the
cellular media 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 neces-
sary to clean your filter, see Section V, Cleaning the Filter.
REV.C4-3-123
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 BE BLOWN OFF WHICH CAN RESULT IN
SEVERE INJURY, DEATH, OR PROPERTY DAMAGE. TO AVOID THIS POTENTIAL
HAZARD, FOLLOW THESE INSTRUCTIONS.
1. BEFORE REPOSITIONING VALVES AND BEFORE BEGINNING THE ASSEMBLY,
DISASSEMBLY, OR ADJUSTMENT OF THE LOCK RING OR ANY OTHER SERVICE
OF THE CIRCULATING SYSTEM: (A) TURN THE PUMP OFF AND SHUT OFF ANY
AUTOMATIC CONTROLS TO ENSURE THE SYSTEM IS NOT INADVERTENTLY
STARTED DURING THE SERVICING; (B) OPEN AIR RELIEF VALVE; (C) WAIT
UNTIL ALL PRESSURE IS RELIEVED.
2. WHENEVER INSTALLING THE FILTER LOCK RING FOLLOW THE CLEANING
FILTER INSTRUCTIONS EXACTLY.
3. ONCE SERVICE ON THE CIRCULATING SYSTEM IS COMPLETE FOLLOW
INITIAL START-UP AND RESTART INSTRUCTIONS EXACTLY.
4. MAINTAIN CIRCULATION SYSTEM PROPERLY. REPLACE WORN OR DAMAGED
PARTS IMMEDIATELY (e.g., lock ring, pressure gauge, relief valve, O-rings, etc.).
5. BE SURE THAT THE FILTER IS PROPERLY MOUNTED AND POSITIONED
ACCORDING TO INSTRUCTIONS PROVIDED.

The filter’s function is to remove suspended matter from the water, but it 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 sanita-
tion requires a free chlorine level of 1 to 2 PPM and a PH range of 7.2 to 7.6.
P/N 99226200 4 REV.C4-3-12WARNING
Failure to operate your filter system or inadequate filtration can cause poor water clarity, obstructing
visibility in your pool. Poor water clarity may obscure objects in the water which, while swimming and
diving, could cause severepersonal injury and death. Never swim in a pool with poor water clarity.
SECTION III. INSTALLATION
To install this filter system, you will need the follow-
ing tools - a screwdriver, wrench, and pliers.
(Refer to photo on front page for completed
assembly)
1. Carefully remove the equipment from the
carton and check for any evidence of damage
due to rough handling or shipping. If any of
the equipment is damaged, immediately noti-
fy the organization where the equipment was
purchased.
2. This filter should be mounted on a level con-
crete slab, or on a platform constructed of
concrete block or brick.
3. Position the mounting base on the slab so
when the pump is mounted, the front (suction
port) of the pump is directly in-line with the
skimmer suction portfrom the pool.
4. Once the pump location is determined, fasten
the pump to the base using twobolts and
retaining nuts.
5. Add three complete wraps of SOXPEHUVtape to
the threads of the hose adapters, see Figure 1,
and the threaded ends of the pump connector,
see Figure 2 and 2A. The tape isincluded in
the kit.

REV.C4-3-125
6. Thread the pump connector, see Figure 2, into the inlet port of the filter, see Figure 3, hand tighten
with an additional 1/2 turn using a wrench until the end of the connector with the union nut is fac-
ing down.
7. Install the O-ring, see Figure 4, into the groove of the pump connector end.
8. Thread the pump connector, see Figure 2a, into the pump outlet port, hand tighten with an addi-
tional 1/2 turn using a wrench.
9. Attach the filter and pump connector assemblies together. This is an O-ring seal and requires hand
tightening only.
10. Screw in the hose adapters into the filter outlet port and the pump suction port, hand tighten an
additional 1/2 turn with a wrench.
11. Slide the clamps over the ends of the hoses. Slide the hoses over the hose adapters and tighten
clamps.
12. Attach the opposite ends of the hoses, see Figure 5, to the skimmer suction port and the pool’s
return inlet fitting port and tighten clamps.
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 pressur-
ized. Pressurized air can cause the lid to be blown off which can result in severe injury,
death, or property damage.
CAUTION
Do not mount electrical controls (on/offswitches, timer,etc.) over the filter. You need to be able to stand
clear of the filter when starting the pump.
Never install a pump in this system that exceeds the maximum pressure of this filter (see filter data
label).
SECTION IV. INITIAL START-UP AND RESTART INSTRUCTIONS
1. Be sure all connections have been made and are secure.
2. OPEN THE AIR RELIEF V
ALVE.
3. STAND CLEAR OF THE FILTER. Start pump allowing the filter tank to fill with water. Close the
air relief valve after a steady stream of water appears.

4. Your filter has now started its filter cycle. You should check that the water is returning to the pool.
5. Check the system for water leaks. If a leak is found, shut off pump before correcting the leak.
6. As the filter removes the dirt and impurities from the pool water, the accumulation will cause the
filter flow to diminish. It is then time to clean the filter’s cellular media elements, see Section V,
Cleaning the Filter.
P/N 99226200 6 REV.C4-3-12WARNING
Failure to operate your filter system or inadequate filtration can cause poor water clarity, obstructing
visibility in your pool. Poor water clarity may obscure objects in the water which, while swimming and
diving, could cause severe personal injury and death. Never swim in a pool with poor water clarity.
SECTION V. CLEANING THE FILTER
1. Cleaning frequency will vary from pool to pool and with other factors such as weather conditions,
heavy rains, dust, pollen, bather load and water chemistry.
2. Turn the pump off, shut off any automatic controls to assure that the system is not inadvertently
started during servicing.
3. Plug the skimmer port and water return port with a rag. This will prevent water from the pool from
running out while servicing.
4. Open the filter air relief valve, and the filter drain plug.
5. Disconnect the pump connector from the pump.
6. Unscrew the locking ring (turning counter-clockwise) from the filter head.
7. Remove the CELLULAR MEDIA ELEMENT from the filter body.
8. Using a garden hose, direct water spray at the CELLULAR MEDIA ELEMENT to dislodge and
wash away any accumulated foreign matter.
9. Clean and remove any debris from inside the filter body.
10. Replace the CELLULAR MEDIA ELEMENT into the filter body.
11. Clean any debris from the O-ring at the top of the filter tank. Apply a silicone lubricant to the O-
ring.
DO NOT USE A PETROLEUM-BASE LUBRICANT ON THE O-RING.

12. Screw the locking ring (clockwise) onto the filter head.
13. Reconnect the pump connector to the discharge port of the pump.
14. Replace the drain cap, hand tighten only.
15. Follow Initial Start Up and System Restart Instructions.
SECTION VI. WINTERIZING THE FILTER

SECTION VIII. PUMP INSTRUCTIONS
1. TO PRIME PUMP - (pump must be off). Turn pump off. Place pump at or below the water level of
the pool (preferably lower than the pool water level. Open the air relief valve. Allow water to flood the
inlet hose and pump housing. Stand clear of the filter and turn the pump on. Close the air relief valve after
asteady stream of water appears. The pump will experience a temporary unstable condition and may be
somewhatnoisy until all air in the system is cleared.

2. 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.
REV.C4-3-129 P/N 99226200
CAUTION
DO NOT RUN PUMP DRY. If the pump is run dry, the mechanical seal will be damaged and external leak-
age will occur. When a seal is damaged, the seal must be replaced.
CAUTION
ALWAYS MAINTAIN PROPER WATER LEVEL IN THE POOL. Water level must be half way up the skimmer
opening. A low water level can cause the pump motor to run dry which will damage the mechanical seal
and cause external leakage.
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.
3. THE ELECTRIC MOTOR
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 war-
ranty is void.
b. The motorsused on these pumps are48 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. Removethe 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 atthe rear of the volute. Be sure the end bell and the shell
marking line up. Securely fasten the motor to the volute.
c. Protect the motor from heat. Provide ample ventilation.
