A. HOW YOUR FILTER WORKS
Your vertical grid diatomaceous earth (D.E.) filter is designed to operate for years with proper maintenance. The filter housing is made of corrosion resistant materials and when installed, operated and maintained in accordance with these instructions, your filter will provide years of service.
An External Air Relief Valve has been factory installed for you safety.
Your filter is charged with D.E. at initial start-up. This D.E. will cover the vertical filter grid cloth within the filter with a thin coating. Dirty water flows from the pool through the control valve on the side of the filter and into the lower side connection of the filter (Item 30). The dirty water flows through the vertical grid elements (Item 17) where dirt is filtered out by the D.E. coating. All grid elements channel cleaned water into a manifold system (Item 13) which exits at the upper side connection (Item 26) and through the control valve to return back to the pool. By diluting the dirty pool water with clean water, the entire pool becomes gradually cleaned. Your filter and pump should be sized to circulate from 2 to 4 times the volume of water in the entire pool through the filter every day to accomplish the cleaning.
As dirt is collected in the coating of D.E. in the filter, the pressure will rise and the flow of water to the pool will be reduced. See other sections in the manual to determine when to clean the filter and how to choose the appropriate cleaning method.
Filter is designed and intended for use to filter
water in swimming pools and spas.
CAUTION
This filter will only remove suspended matter and does not sanitize the pool. The pool must be sanitized and pH balanced for sparkling clear water. Your filtration system must be configured and sized to meet your local health codes.
NOTE
Part no's in parenthesis refer to the replacement parts as shown in the exploded drawing on page 11 of this manual.
WARNING
Failure to operate your filter or inadequate filtration can cause poor water clarity that could obstruct visibility in your pool and can allow diving in shallow pool area, or diving into or on top of obscured objects which can cause serious bodily injury or drowning.
Clear water is the result of proper filtration as well as proper water chemistry. Pool chemistry is a specialized area and you should consult your local pool service specialist for specific help or instructions. 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.

SECTION II. FILTER INSTALLATION.
A. GENERAL INFORMATION
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE CIRCULATING SYSTEM, e.g., CLAMP, PUMP, FILTER, VALVE(S), 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 VALVE(S) 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 THE AIR RELIEF VALVE; (C) WAIT UNTIL ALL PRESSURE IS RELIEVED.
2. WHENEVER INSTALLING THE FILTER CLAMP FOLLOW THE FILTER 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, valve(s), O-rings, etc.
5. BE SURE THAT THE FILTER IS PROPERLY MOUNTED AND POSITIONED ACCORDING TO INSTRUCTIONS PROVIDED.
WARNING
1. Check carton for any evidence of damage due to rough handling in shipment. If carton or any filter components are damaged, notify freight carrier immediately.
2. After inspection, carefully remove filter components from carton.
3. Mount filter on a permanent slab, preferably concrete poured in a form or on a platform constructed of concrete block or brick. DO NOT use sand to level the filter or for pump mounting, as it will wash away.
Provide space and lighting for routine maintenance access, see Figure 1.
DO NOT mount electrical controls over filter.
In respect for the potential for injury from any pressurized system, it is a good common sense
precaution to always stand clear of the filter whenever starting the pump.
4. If you have a Multiport Valve, assemble the valve to tank, being sure O-rings on valve fittings are in place and are clean. Use a lubricant applied lightly, such as petroleum jelly, silicone grease, Mytilube or similar product on O-rings and O-ring grooves prior to assembly.
5. If you have a two position slide valve, align the valve with tank so that the handle is toward the top of the tank, push valve into ports and turn the valve nuts snugly on tank fittings. It is not necessary to cinch valve nuts to tank fitting beyond hand tightness.
6. Assemble piping and pipe fittings to pump and valve. All piping must conform to local and state plumbing and sanitary codes.
7. Use Teflon Tape or Pastojoint Stick on all male connections of pipe and fittings. Use only pipe compounds suited for plastic pipe. Support pipe to prevent strains on filter, pump or valve.
8. Long piping runs and elbows restrict flow. For best efficiency use the fewest possible fittings, large diameter pipe (at least 1½ in. preferably 2 in.) and locate equipment as close to the pool as possible.
9. A check valve is recommended between the filter and heater to prevent hot water “back up” which will damage the filter and valve.
10. The maximum operating pressure of this unit is 50 pounds per square inch, (psi). Never operate this filter above this pressure or attach a pump to this filter that has more than 50 psi shut off pressure.
Rev. B 5-14-01 3 P/N 191600
Figure 1.
Page 4
CAUTION
Never install a chlorinator upstream of the filter or heater - always downstream and with a check valve in between the chlorinator and filter or heater. Highly chlorinated water can damage metallic system components.
CAUTION
A positive shut off valve is NOT recommended at the outlet of the filtering system. If the system is ever run with such a valve closed, the internal air relief system becomes inoperative and increase the risk of vessel separation. Additionally, running the system with no flow will seriously damage the equipment.
CAUTION
A positive shut off valve is also NOT recommended at the waste port of the valve. If the system is ever run with such a valve closed, the filter pressure will go abnormally high and increase the risk of vessel separation. Additionally, running the system with no flow will seriously damage the equipment.
CAUTION
Never store pool chemicals within 10 ft. of your pool filter and pump. Pool chemicals are corrosive and should always be stored in a cool, dry and well ventilated area.
WARNING
Chemical fumes and/or spills can cause severe corrosive attack to the filter and pump structural metallic components. Structurally weakened filter components can cause filter or valve attachments to separate and could cause severe bodily injury or property damage.
B. INITIAL START-UP
1. On a new pool, clean the pool before filling with water. Excess dirt and large particles can cause damage to pump and filter.
2. Check clamp assembly for tightness. See "FILTER DISASSEMBLY/ASSEMBLY PROCEDURES-SECTION II., C.". for more information.
WARNING
Improper tank assembly could cause the tank top to blow off and cause severe bodily injury and / or property damage.
3. Move valve handle to filter position. Open air bleeder screw (Item 1) on the filter top. Check pump strainer pot to be sure it is full of water. Replace pump lid.
WARNING
Air entering filter and/or the filter unit not closed correctly can cause the tank top to blow off and could cause severe bodily injury and/or property damage.
4. Open all suction and return line valves. Stand clear of filter during the following operations.
5. Start pump. The tank will fill with water and expel air from air bleeder.
6. Remove the skimmer lid, put the recommended amount of Diatomaceous Earth (D.E.) into the skimmer. The D.E. will be drawn into the filter and deposited evenly upon the grid elements. Now the filter is providing the pool with bright, clean water.
CAUTION
Do not operate filter without D.E. charge for more than two minutes. Do not use more than the recommended amount of D.E. in your filter. Operating filter without D.E. can damage filter grid elements.
D.E. RECOMMENDATION
The amount of D.E. should be 1 pound for each 10 square feet of filter area, see D.E. Precoat Requirements.

7. On a new pool installation, it will require approximately one week to obtain and maintain the water clarity of which
your filter is capable. It is recommended to disassemble and clean the filter after initial pool clean up (approximately 48 hours of operation). Follow the instructions given in this manual for disassembly, cleaning and reassembly.
8. Be sure to note the operating pressure of the filter when it is clean and properly charged with D.E.. As the filter
removes dirt from the pool, the pressure will gradually increase. As a guide, when the pressure has increased 7 to 10 psi from the initial reading, it is time to backwash the filter.
a. MY ORIGINAL STARTING PRESSURE IS ___________ psi (pounds per square inch). I SHOULD
BACKWASH (CLEAN) THE FILTER AT __________ psi.
C. FILTER DISASSEMBLY/ASSEMBLY
Before Disassembling Filter:
Backwash filter according to instructions under, see "FILTER BACKWASH PROCEDURE - SECTION II., F.", but stop after instruction (# 7). Do not precoat with new D.E.
DISASSEMBLY:
1. Be sure pump is turned off and all pressure has been released from system.
WARNING
Releasing clamp with pressure on system could cause tank lid to blow off, causing severe injury or major property damage!
NEVER adjust, tighten or loosen “V” band clamp when tank is under pressure!
2. Remove filter drain plug and drain all water from tank.
WARNING
Clamp hardware and filter surface could have sharp edges which can cause bodily injury if improperly handled. Please use caution when performing the following procedures.
3. Loosen clamp nuts alternately until one is removed. Remove spring and washers
noting part orientation. Lift clamp assembly off of filter.
4. Tank halves may have a tendency to stick together. In order to separate tank
halves, it may be necessary to strike the tank top using the palm of your hand with a glancing upward movement, see Figure 2. Proceed gradually around the tank using this motion until the top loosens.
5. Being careful not to damage tank seal, lift upper tank shell off of lower tank shell.
ASSEMBLY:
WARNING
Always visually inspect filter components during normal servicing to insure structural safety. Replace any item which is corroded, bent or otherwise visually deteriorated. Deteriorated filter components can allow the filter top or attachments to blow off and could cause severe bodily injury or property damage.
1. Thoroughly clean air relief filter screen on top of manifold EVERY time filter is
opened. Be sure to remove all debris from screen.
2. Inspect tank seal, (Item 21), for cuts, nicks, etc. If damaged, replace with a new
one.
3. Clean tank seal area of tank shell (both halves) and tank seal.
4. Inspect, clean and lubricate the O-ring, (Item 18), on the upper pipe assembly,
(Item 19).
5. Clean the metal band which supports the tank seal on the inside of the filter tank.
Note that this band has a formed bead in its center to locate it in the assembled tank, see Figure 3.
6. Lubricate the tank seal with petroleum jelly, silicone grease, Mytilube or similar
product.
Figure 2.
Figure 3.
Rev. B 5-14-01 5 P/N 191600
Page 6
7. Carefully install tank seal and upper tank shell.
CAUTION
Be sure upper tank shell contacts tank seal surface evenly and seal area is clean and free from dirt, etc. Debris on seal surfaces can cause leaks.
8. Install clamp springs, washers and units. Tighten nuts evenly and alternately until spring coils touch each other. Tap clamp around tank with rubber hammer to assist seating of clamp.
9. Use only those components supplied with filter or Pentair Pool Products replacement parts when dealing with the bands and spring tensioning devices.
WARNING
Use of non original equipment parts on band clamps with spring tensioning devices may cause these tensioning devices to malfunction. Improper clamp installation could cause the filter top to blow off and cause severe personal injury and/or property damage.
WARNING
Do not over tighten the clamp band. Tightening the clamp band beyond recommended procedures may damage the clamp band and cause unexpected failure, sudden release of pressure and injury or damage. Over tightening may also deform tank seal, causing leakage at band clamp. Corroded components cannot be repaired and must be replaced. If you are experiencing corrosion, consult your pool service company or dealer.
D. FILTER CARE
1. Keep pool water pH at the recommended levels (7.2 to 7.6) as well as other pool chemicals at their proper levels to avoid deterioration of the stainless steel tank.
2. The tank is stainless steel, but is not corrosion proof if the pool chemistry is allowed to act aggressively. Under such conditions the steel can experience pitting which will be most apparent in the flange area where the O-ring seats and seals the two halves of the filter.
3. To minimize this tendency, it is recommended to keep the flanges clean of surface corrosion by removing any corrosion with fine emery cloth or stainless steel wool (DO NOT use steel wool) and coat the O-ring with a substance such as petroleum jelly, silicone grease, Mytilube or a similar product.
4. If corrosion is allowed to progress, the filter will eventually leak at the O-ring seal. This process cannot be arrested or corrected by tightening the closure band, though that may temporarily stop the leak.
E. CLEANING FREQUENCY
1. The filter on a new pool should be backwashed, disassembled and cleaned after approximately 48 hours of operation to clean out plaster dust and/or construction debris.
2. Once a new pool has been established, the dirt collected will gradually increase the filter pressure. When the filter pressure increases 7 to 10 psi over the initial pressure or when the flow has been reduced by about 1/3 from when the filter was clean, it is time to backwash the filter. Different areas and water conditions will have different normal cleaning intervals.
3. If at any time the starting pressure after backwashing the filter indicates 2 to 6 psi higher than normal starting pressure, it is time to perform a manual filter cleaning or a chemical cleaning procedure in the worst cases.
4. It is a good idea to disassemble the filter and perform a chemical leaning procedure twice a year to remove accumulated body oils, etc.
5. In areas that have freezing winter temperatures protect equipment by backwashing and either manually cleaning or chemically cleaning before winter storage. Be sure all water is drained from the filter using the drain plug. The air bleeder must be opened as well as all other valves.
P/N 191600 6 Rev. B 5-14-01

F. FILTER BACKWASH PROCEDURE
NOTE
When backwashing with a separation tank, see Separation Tank Owner’s Manual for instructions.
1. Stop pump. Ensure that the backwash line is open and any valving is adjusted to allow the free flow of water.
2. Change valve positions.
a. If using Multiport Valve, set to backwash position.
b. If using Two-Position Slide Valve, raise handle to fully extended position.
3. Stand clear of filter.
4. Start pump, this will circulate water backwards through the filter to flush D.E. cake and contaminants into the separation tank or to waste.
5. If system has a sight glass, backwash until water in glass runs clear.
6. If system does not have a sight glass:
a. Backwash one minute.
b. Stop pump and change valve position.
1.) If using Multiport Valve, set to rise position.
2.) If using Two-Position Slide Valve, push handle down to filter position.
WARNING
To prevent equipment damage and possible bodily injury and/or property damage, always turn the pump off before changing the valve positions.
c. Stand clear of filter.
d. Restart pump, run for one minute.
e. Repeat steps a,b,c and d three times.

A
A. CLAMP KIT INSTALLATION
1. Remove contents of kit and check against parts list at end of instructions to insure all components are present.
2. Backwash filter according to instructions under, see “FILTER BACKWASH PROCEDURE" - SECTION II., F," in your filter manual: INSTALLATION, OPERATION & SERVICE MANUAL. Stop after instruction #7. Do not precoat with new D.E.
3. Be sure pump is turned off and all pressure has been released from system.
WARNING
Releasing clamp with pressure on system will cause tank lid to blow off, causing severe injury or major property damage! NEVER adjust, tighten or loosen “V” band clamp when tank is under pressure!
4. Remove filter drain plug and drain all water from tank.
CAUTION
Clamp hardware and filter surface could have sharp edges which can cause bodily injury if improperly handled. Please use caution when performing the following procedures.
5. Loosen clamp nuts alternately until one is removed. Lift clamp assembly off of filter.
NOTE
If you are installing one of the following replacement kits, remove tank top at this point and refer to AIR RELIEF INSTALLATION on next page; Kit P/N 181013, 181014, 181015, 181016, 181017, 181018, 181019, 181020, 181021, and 181022.
6. Remove second nut from clamp assembly. If replacing entire band assembly (Kit: P/N 181011 for NS and Kit: P/N 181012 for FNS), the old band should be discarded and the following instructions will apply to installation of the new band assembly. The threaded end of the T-bolt should protrude through the trunnion per Figure 1.
7. Place one of the washers (with the small hole 5/16 in. inside diameter) on the threaded end of the T-bolt and slide washer down bolt until it is against the trunnion, see Figure 1.
8. Place one of the washer (with the large hole- 7/16 in. inside diameter for NS and 17/32 in. inside diameter for FNS) over the shank of the brass nut. Place one of the springs over the shank of the brass nut so that the washer with the large hole is captured between the end to the spring and the head of the brass nut, see Figure 2.
9. Thread shank of nut onto T-bolt, 2 turns maximum.
10. Preassemble second washer with large hole, nut and spring for opposite side of opposite side of band clamp assembly.
11. Insure flanges on tank halves are free of dirt and or D.E.
12. Place clamp around tank flange making sure threaded end of T-bolt protrudes through trunnion as in Figure 1.
13. Place remaining washer (with the small hole 5/16 in. inside diameter) on the threaded end of the T-bolt and slide washer down bolt until it is against the trunnion, see Figure 1.
14. Thread shank of nut onto T-bolt 2 turns minimum. If end to T-bolt does not protrude through trunnion far enough to engage shank of nut, make sure that first spring assembly is tight against trunnion per Figure 3, and band is tight against tank.

15. Tighten nuts evenly and alternately until spring coils touch each other. Tap clamp around tank with rubber hammer to assist seating of clamp.
16. Use only those components supplied in this kit or Pentair Pool Products replacement parts when dealing with the hands and spring tensioning devices.
WARNING
Use of non original equipment parts on band clamps with spring tensioning devices may cause these tensioning devices to malfunction, resulting in improper clamp installation. Could cause the filter top to blow off and cause severe personal injury and/ or property damage.
WARNING
Do not over tighten the clamp band. Tightening the clamp band beyond recommended procedures may damage the clamp band and cause unexpected failure, sudden release of pressure and injury or damage.
17. Follow instructions under “INITIAL START-UP - SECTION II., B.” of your filter INSTALLATION, OPERATION & SERVICE MANUAL to return your filter to operation.
B. AIR RELIEF INSTALLATION
1. Make sure steps 1 through 5 outlining pump shut down and clamp removal have been completed.
2. Thoroughly clean air relief filter screen on top of manifold. Be sure to remove all debris from screen.
3. Inspect tank seal for cuts, nicks, etc. If damaged, replace with a new one.
4. Prepare tank top for alteration by removing existing air bleeder assembly and cleaning tank top inside and out. If you received a new top with the 2-3/8 in. diameter hole in it, skip to step 8.
5. For FNS (Fiberglass) tanks, use a 2-3/8 in. diameter hole saw to carefully cut a larger hole in the tank top. The 2-3/8 in. diameter hole should be centered on the original 13/32 in. diameter hole as shown in Figure 4.
Figure 4.
NEW 2-3/8" DIAMETER HOLE
EXISTING 13/32" DIAMETER HOLE
CAUTION
Do not allow hole saw to scratch the outside surface of the tank top past the new 2-3/8 in. Diameter hole. This is an o-ring sealing surface and scratches in this area will cause the o-ring sealing surface and scratches in this area will cause the o-ring seal to leak.
6. Using heavy gloves and a dust mask (same as used for installing fiberglass insulation) for protection, carefully remove any loose fibers from the hole. Lightly sand the inside of the hole with a 200-220 grit non-clogging sand screen such as Carborundum Abrasives’ S/C Sand Screen M755S silicone carbide 220 grit. DO NOT enlarge the hole past 2-13/32 in. diameter.
CAUTION
The sanding operation will generate glass fibers and loose dust. Protect yourself from these by the use of gloves and mask as noted in #6 above. Without these protective items, glass fibers and loose dust could be imbedded in the skin and/ or inhaled, possibly causing injury and or irritation.
7. For NS (Stainless Steel) tanks, a good quality steel punch must be used to make the larger hole. It may be necessary to use 2 punches; (1) to enlarge the hole from 13/32 in. diameter to accommodate a larger mandrel for the 2-3/8 in. diameter punch and (1) 2-3/8 in. diameter punch. The punches must be capable of punching though .060 thick steel. Follow punch in making the larger hole. The 2-3/8 in. diameter hole should be centered on the original 13/32 in. diameter hole as shown in figure 4. The final hole size should be 2-3/8 in. diameter minimum and 2-13/32 in. diameter maximum. Remove any metal burrs in the hole with a file.
CAUTION
Do not allow punch or file to scratch the outside surface of the tank top past the new 2-3/8 in. Diameter hole. This is an o-ring sealing surface and scratches in this area will cause the o-ring to leak. Do not enlarge the hole past 2-13/32 in. Diameter. Do not use a hole saw to modify stainless steel tanks.
8. Remove Air Relief from box and check parts list at end of instructions to insure that all the components are present.
