SECTION I. FILTERINSTALLATION.
1. The filter should be mounted on a level concrete slab. Position the filter so that the instructions, warnings and pressure
gauge are visible to the operator. Also, position the filter so that the piping
connections, control valve and drain port are convenient and accessible for
servicing and winterizing.
2. Install electrical controls (e.g., on/off switches, timers, control systems,
etc.) at least five (5) feet from the filter. This will allow you enough room to
stand clear of the filter during system start up.
3. Provide sufficient clearance around the filter to permit visual verification
that the clamp is properly installed, see Figure 1.
4. Provide sufficient space above the filter to remove the filter lid or control
valve for cleaning and servicing. This distance will vary with the model of
filter you are using. See Table 1 for the required vertical clearance. Figure1.

P/N•Núm/Pte.•Réf.P/N99226000 2 Rev.H•Rev.H•Rév.H 12-9-99
5. WheninstallingtheHigh Flow™manualairreliefvalve
position the filter to safely direct water drainage. Rotate the
High Flow™ manual air relief valve to safely direct purged air
or water. Water discharged from an improperly positioned
filter or valve can create an electrical hazard as well as damage
to property.
WARNING
Risk of electrical shock or electrocution. Position the filter and High Flow™ manual air relief valve to safely direct water
drainage and purged air or water. Water discharged from an improperly positioned filter or valve can create an electrical hazard
that can cause severe injury as well as damage property.
6. Your filter requires one of the following Pentair Pool Products accessories which must be purchased separately.
a. Push-pull valve.
b. Multiport valve.
c. Bulkhead union set.
7. Make all plumbing connections in accordance with local plumbing and building codes. Filter plumbing connections are
provided with an O-ring seal. Use only a silicone base lubricant on the O-rings. Do not use pipe joint compound, glue or
solvent on the bulkhead connections to avoid damage to the O-rings.
CAUTION
For Multiport control valves with threaded ports use only Teflon tape, 100% pure Teflon paste (non-petroleum base), Permatex #2 sealant
on all threaded pipe connections, except fittings with O-rings. Use of other pipe joint compounds can damage components of this system
and cause leaks. For control valves with slip ports, use only ABS to PVC solvent welding adhesive.
8. The maximum working pressure of this filter is 50 psi, see Table 2. Never subject this filter to pressure in excess of this amount
- even when conducting hydrostatic pressure tests. Pressures above maximum working pressure can cause the lid to be blown
off, which can result in severe injury, death or property damage.
When performing hydrostatic pressure tests or when testing for external leaks of the completed filtration and plumbing
system, insure that the Maximum Pressure that the filtration system will be subjected to DOES NOT EXCEED THE
MAXIMUM WORKING PRESSURE OF ANY OF THE COMPONENTS CONTAINED WITHIN THE SYSTEM. In most
cases, the maximum pressure will be stated on each component of the system.
If doubt exists as to the pressure to which the system will be subjected, install an ASME approved automatic Pressure Relief
or Pressure Regulator in the circulation system for the lowest working pressure of any of the components in the system.
SECTIONII. FILTEROPERATIONANDCLEANING.
WARNING
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE CIRCULATING SYSTEM (E.G., CLAMP,
PUMP, FILTER, VALVES, ETC.) IS SERVICED, AIR CAN ENTER THE SYSTEM AND BECOME PRESSURIZED.
PRESSURIZED AIR CAN CAUSE THE LID OR CONTROL VALVE TO BLOW 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 CLAMP 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 HIGH FLOW™ MANUAL AIR RELIEF VALVE; (C) WAIT UNTIL ALL PRESSURE IS RELIEVED,
PRESSURE GAUGE MUST READ ZERO (0).
2. WHENEVER INSTALLING THE FILTER CLAMP, FOLLOW THE FILTER LID AND CLAMP INSTALLATION
INSTRUCTIONS EXACTLY.
3. ONCE SERVICE ON THE CIRCULATING SYSTEM IS COMPLETE, FOLLOW SYSTEM RESTART INSTRUCTIONS
EXACTLY.
4. MAINTAIN CIRCULATION SYSTEM PROPERLY. REPLACE WORN OR DAMAGED PARTS IMMEDIATELY (E.G.,
CLAMP, PRESSURE GAUGE, RELIEF VALVE, O-RINGS, ETC.).
5. BE SURE THAT THE FILTER IS PROPERLY MOUNTED AND POSITIONED ACCORDING TO INSTRUCTIONS
PROVIDED.

A. GENERALINFORMATION-HOWYOURFILTERWORKS.
1. Your high rate sand 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 special filter sand to remove dirt particles from the water. Dirt is collected in the filter by the sand bed as
water flows through the filter. Water enters the filter through the valve on top of the filter (or the top bulkhead fitting in the
case of side mounted control valves). It is then distributed evenly downward, across and through the sand bed. The dirt is
removed by the sand and the clean water flows through the piping (laterals) at the bottom of the filter up through the center
pipe back to the valve on top of the filter (or out of the lower bulkhead on side mounted filters), where the clean water is
returned to the pool through the piping.
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 rate and a rise in the pressure of the filter. Eventually the filter sand will have removed
so much dirt and the filter pressure risen to such a point that it will be necessary to clean (backwash) your filter.
By setting the control valve on the top or side of the filter to the backwash position, the flow direction of water is reversed
through the filter so that the water is directed to the bottom of the filter and up through the sand bed flushing the dirt and
debris out through the waste line. Once the backwash procedure is complete, the valve must be returned to its filter position to
resume normal filtration.
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 chemically 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
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 MAY EXPOSE SWIMMERS OR DIVERS TO THE RISK OF SEVERE INJURY OR
DEATH. NEVER SWIM IN A POOL WITH POOR WATER CLARITY.
2. This filter operates under pressure. When clamped properly and operated without air in the water system, this filter will
operate in a safe manner.
3. The pressure gauge is the primary indicator of how the filter is operating. Maintain your pressure gauge in good working order.
CAUTION
The following information should be read carefully since it outlines the proper manner of care and operation for your filter system. As a
result of following these instructions and taking the necessary preventative care, you can expect maximum efficiency and life from your
filtration system.
B. FILTERMEDIA.
1. Media - Your sand filter uses a #20 grade silica filter sand for its media (.45 - .55 mm). It should be free of all limestone or clay.
Most pool supply and building material stores carry silica sand. See Table 2 for the appropriate amounts of silica sand.
Table 2. Maximum
Product # Filter Diameter Filter Area Sand Qty. Working PSI
58920100 26 in. 3.5sq.ft. 225lbs. 50psi
58920200 30 in. 4.6sq.ft. 350lbs. 50psi
58920300 36 in. 6.5sq.ft. 575lbs. 50psi
2. Remove the lid from your filter and install the sand funnel on the top of the filter tank. It is important to swing the diffuser
basket(s) to a horizontal position before installing the funnel. Fill the tank about half full of water. Pour the silica sand into the
top of the filter tank slowly, so that the weight does not damage the lateral assembly in the bottom of the tank or the overdrain
plumbing near the top of the tank.
3. After filling the filter tank with the appropriate amount of silica sand, remove the sand funnel and wash away any loose sand
from the opening of the filter tank. Straighten the diffuser basket(s) up into the vertical operating position if you previously
moved them down.
4. To install lid, follow procedures in Section C, Lid and Valve Installation Instructions.

P/N•Núm/Pte.•Réf.P/N99226000 4 Rev.H•Rev.H•Rév.H 12-9-99
CAUTION
For Multiport control valves with threaded ports use only Teflon tape, 100% pure Teflon paste (non-petroleum base), or Permatex #2
sealant on all threaded pipe connections, except fittings with O-rings. Use of other pipe joint compounds can damage components of this
system and cause leaks. For control valves with slip ports, use only ABS to PVC solvent welding adhesive.
5. The maximum working pressure of this filter is 35 or 50 psi, see Table 2. Never subject this filter to pressure in excess of this
amount - even when conducting hydrostatic pressure tests. Pressures above maximum working pressure can cause the lid to be
blown off, which can result in severe injury, death or property damage.
When performing hydrostatic pressure tests or when testing for external leaks of the completed filtration and plumbing
system, insure that the Maximum Pressure that the filtration system will be subjected to DOES NOT EXCEED THE
MAXIMUM WORKING PRESSURE OF ANY OF THE COMPONENTS CONTAINED WITHIN THE SYSTEM. In most
cases, the maximum pressure will be stated on each component of the system.
If doubt exists as to the pressure to which the system will be subjected, install an ASME approved automatic Pressure Relief
or Pressure Regulator in the circulation system for the lowest working pressure of any of the components in the system.
C. LIDINSTALLATIONINSTRUCTIONS.
TheseinstructionsMUST BEFOLLOWEDEXACTLY to preventthe lid orvalvefrom blowingoffduring systemrestart
or later operation:
1. Before working on any part of the circulating system, (e.g. clamp, pump, filter, valves, etc.) perform the following steps:
a. Turn the pump off and shut off any automatic controls to ensure that the system is not inadvertently started during
servicing.
b. Open the High Flow™ manual air relief valve.
c. Wait until all pressure is relieved. Never attempt to assemble, disassemble or adjust the lid while there is any
pressure in the filter.
2. Be sure that the chamfered sealing surface inside of the brass, or plastic flange at the top of the tank is clean and free of any
sand or debris. Apply a light coating of SILICONE BASE LUBRICANT to the lid O-ring and install into the opening in the
top of the filter tank.
NOTE
30 in. FILTERS ARE SHIPPED from the factory ready to accept a 2 in. control valve. If you wish to use the 1.5 in. control
valve, it is necessary to remove the 2 in. X 2 in. extension from the stand pipe and replace it with the 2 in. X 1.5 in. extension
fitting. This fitting is included in the accessory kit.
3. Installthelid inthe followingmanner:
a. Thread the plastic lid into the top tank opening until the O-ring makes contact, then tighten an additional 1/4 to 1/2 turn.
4. Follow the system restart instructions in Section D.
WARNING
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE CIRCULATING SYSTEM (e.g., CLAMP, PUMP,
FILTER, VALVES, ETC.) IS SERVICED, AIR CAN ENTER THE SYSTEM AND BECOME PRESSURIZED. PRESSURIZED AIR CAN
CAUSE THE LID OR VALVE TO BE BLOWN OFF WHICH CAN RESULT IN SEVERE INJURY, DEATH, OR PROPERTY DAMAGE.

E. CONTROLVALVEFUNCTIONS.
1. Side Mounted Push-pull valves have two operating positions, see Table 3.
a. Filter, T-handle is fully extended to its uppermost position.
b. Backwash, T-handle is fully compressed to its lowermost position.
2. Rotary type multiport control valves offer more operating positions and allow more options on how to direct the flow of water
in your pool system.
a. 8-Way Multiport valves provide all of the following functions, see Table 3.
TABLE 3
FILTER From pump, through valve, downward through filter sand bed, back through laterals and piping to valve return
port, and back to the pool. This position is used for normal filtering and vacuuming to clean the pool water.
BACKWASH From pump, through valve, down through piping and laterals, up through filter sand bed to valve, and out
waste port. This position is used for cleaning filter by reversing flow.
RINSE From the pump, through valve, downward through filter sand bed, back through laterals and piping to valve
and out waste port. This position is used for start-up cleaning and resettling filter bed after backwashing.
WASTE From pump, through valve (bypasses filter) and goes to waste port. This position is for vacuuming directly to
waste, lowering pool level, or draining pool.
CLOSED NO FLOW IN THIS POSITION - DO NOT USE THIS SETTING WITH PUMP OPERATING.
RECIRCULATE From pump, through valve, bypasses filter and goes to return port and back to pool. This position is for
circulating water without going through filter.
SERVICE NO FLOW IN THIS POSITION - DO NOT USE THIS SETTING WITH PUMP OPERATING. It allows the
removal of the handle pin for servicing.
WINTERIZE For areas that have freezing temperatures during the winter.
F. FILTERSTARTUP-INITIALSANDBEDRINSE.
1. Valve operations, with pump shut off:
a. Push-pull backwash valve.
(1) Push handle down with slight twisting motion as far as it will go.
(2) Lock upper pin in cap.
(3) OpenHighFlow™manualairreliefvalveonthefilter.
(4) Proceed through steps 2 to 3 which follow.
b. Multiport rotary valve.
(1) Position valve to “Backwash” setting.
(2) OpenHighFlow™manualairreliefvalveonthefilter.
(3) Proceed through steps 2 to 3, which follow.
2. Follow steps in Section D, System Restart. On initial start up the pump must be primed by filling the hair and lint strainer with
water You may have to do this several times.
3. Your filter is now backwashing accumulated dust or dirt from the new silica sand bed. Backwash for two (2) minutes, or until
water is flowing clear out the backwash line, or appears clear in sight glass, then shut off pump.
G. FILTERSTARTUP-POOLFILTRATION.
1. Valve operations, with pump shut off:
a. Push-pull backwash valve.
(1) Twist to unlock plunger.

P/N•Núm/Pte.•Réf.P/N99226000 6 Rev.H•Rev.H•Rév.H 12-9-99
(2) Raise the handle as far as it will go.
(3) Turn handle clockwise to lock under pin in underside of cap.
(4) Proceed through steps G.2 to G.3, which follow.
b. Multiport rotary valve.
(1) Position valve to “Filter” setting. This is your normal flow from the pump through the filter back to the pool.
(2) Proceed through steps G.2 to G.3, which follow.
2. Follow steps in Section D, System Restart. Your filter is now in full operation. Note the original starting pressure on the gauge.
3. Backwash your filter when pressure reads between 5 to 11 psi over the original starting pressure, see Step G.5. When your
filter builds up pressure from its starting point, then your filter is performing its function. However, this buildup of pressure
will vary because of different bathing loads, temperature, weather conditions, etc.
a. MY ORIGINAL STARTING PRESSURE IS _____ psi (pounds per square inch). I SHOULD BACKWASH AT
_____ psi
NOTE
Small grains of sand may leave the filter during backwashing or may even appear at the return line when filter is first started
up. This is characteristic of permanent media filters.
WARNING
Always turn pump off before changing valve positions. CHANGING VALVE POSITIONS WHILE THE PUMP IS RUNNING CAN DAMAGE
THE CONTROL VALVE, AND MAY RESULT IN PERSONAL INJURY OR PROPERTY DAMAGE.
4. Check the system for water leaks. If a leak is found, shut pump off and relieve system pressure, before correcting the leak.
5. As the filter removes dirt and impurities from the pool water, the accumulation will cause the filter pressure to rise and the flow
to diminish. It is time to backwash the filter if you are using 1hp or smaller pump and the pressure gauge reading is 5 to 7 psi
higher than the clean filter reading noted in Step G.3, above. For systems with larger than 1 hp pumps, this pressure rise willbe
in the 9 to 11 psi range before it is time to backwash.
CAUTION
To prevent damage to the pump and filter and for proper operation of the system, clean pump strainer and skimmer baskets regularly.
H. FILTERCLEANING-CLEANINGFREQUENCY.
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. Check the pressure gauge reading on a regular basis. If you have a 1 HP or smaller pump,
backwash when the pressure gauge reading increases 5 to 7 psi over the initial clean filter reading. With larger pumps,
backwash when the increase is 9 to 11 psi.
2. It is important NOT to backwash the filter solely on a timed basis such as every two days. Backwashing too frequently
actually causes poor filtration.
I. FILTERCLEANING-FILTERBACKWASHPROCEDURE.
1. Since the sand media bed is the key to efficient filtration in this type filter system, that media bed should be visually inspected
at least once each year.
WARNING
Always turn pump off before changing valve positions. CHANGING VALVE POSITIONS WHILE THE PUMP IS RUNNING CAN DAMAGE
THE CONTROL VALVE, AND MAY RESULT IN PERSONAL INJURY OR PROPERTY DAMAGE.
2. Turn the pump off, shut off any automatic controls to ensure that the system is not inadvertently started during servicing.
3. Open the High Flow™ manual air relief valve and waste drain valve, or plug, if your system has one. Ensure that suction and
backwash lines are open so that water is free to come from the pool and flow out the backwash line.
4. Remove hair and lint pot lid from pump and clean basket. Replace basket, refill hair and lint pot with water, install lid and
clamp securely.

5. ValveOperations:
a. Push-pull backwash valve.
(1) Push handle on valve down with slight twisting motion as far as it will go.
(2) Lock upper pin in cap.
(3) Proceed through steps I.6 to I.11, which follow.
b. Multiport rotary valve.
(1) Position valve to ‘Backwash’ setting.
6. Stand clear of the filter and start pump. Filter is now running in its backwash mode. Close High Flow™ manual air relief valve
only after a continuous stream of water is flowing from the valve.
7. Backwashfilterforapproximately3-5minutes oruntilbackwashwaterisclean.
8. Turn off pump. Set control valve back to filter position and open High Flow™ manual air relief valve again.
a. Push-pull backwash valve.
(1) Twist to unlock plunger; then raise handle as far as it will go.
(2) Turn handle clockwise to lock upper pin in underside of cap.
b. Multiport rotary valve.
(1) Position valve to ‘Filter and Vacuum to Pool’ setting.
9. Stand clear of the filter and start pump. Close High Flow™ manual air relief valve only after a continuous stream of water is
flowing from the valve.
10. The filter has now started its filtering cycle. Check that there is water returning to the pool and take note of the filter pressure.
11. The filter pressure in step I.7 above should not exceed the pressure originally observed on the filter when it was initially
started. If, after backwashing, the pressure is 4 to 6 psi above the start condition, it may be necessary to change the sand in the
filter.
NOTE
Over a period of time certain foreign matter and materials can become imbedded in the top of the sand media bed and will successfully resist
being flushed out during the backwash cycle. During inspection as noted above, this foreign material and any contaminated sand should be
removed from the tank. Replace any old sand removed with new clean silica sand. Replace tank lid or valve and carefully follow instructions
in Section C, Lid and Valve Installation Instructions.
J. WINTERIZINGTHEFILTER.
1. In areas that have freezing winter temperatures the pool equipment must be winterized to protect it from damage.
2. Backwash the filter. Shut off the pump, any automatic controls and set the rotary multiport control valve to the winterize
position. For Push-pull valve equipped filters, leave the valve in the backwash (T-handle down) position.
3. Remove the small knurled drain port cap at the bottom of the filter.
NOTE
Remove ONLY the drain port cap to drain water from filter.
CAUTION
Removing the entire fitting will drain the sand. The filter will drain slowly. Leave the drain port cap off and store it during the time the
system is shut down.
CAUTION
The rotary multiport control valve should be left in the winterize position during the shutdown season so that the rubber seal of the valve
diverter has no pressure on it. Failure to do so can damage the valve’s spider gasket which can cause property damage from leaking
water.
4. Drain all appropriate system piping.
5. It is recommended that the pump and filter be covered with a tarpaulin or plastic sheet to inhibit deterioration from the weather.
