IMPORTANT SAFETY PRECAUTIONS (continued)
WARNING —Due to the potential risk that can be involved it is recommended that the pressure test be kept to the
minimum time required by the local code. Do not allow people to work around the system when the
circulation system is under pressure test. Post appropriate warning signs and establish a barrier
around the pressurized equipment. If the equipment is located in an equipment room, lock the door
and post a warning sign.
Never attempt to adjust any closures or lids or attempt to remove or tighten bolts when the system is
pressurized. These actions can result in a separation or failure of system components. This
instantaneous release of energy can cause components to be accelerated to high velocities and to
travel far distances. These components could cause severe personal injury or death if they were to
strike a person.
WARNING —Risk of electrical shock or electrocution.
This pool filter must be installed by a qualified pool serviceman in accordance with the National
Electrical Code and all applicable local codes and ordinances.
Always disconnect power to the pool equipment at the circuit breaker before servicing any of the
equipment. Ensure that the disconnected circuit is locked out or properly tagged so that it cannot be
switched on while you are working on the pool equipment. Failure to do so could result in serious injury
or death to serviceman, pool users or others due to electric shock.
Position the filter and the 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 personal injury as well as damage property.
WARNING —To reduce the risk of injury, do not permit children to use this product unless they are closely
supervised at all times.
CAUTION — This filter is for use with permanently installed pools and may also be used with hot tubs and spas if
so marked. Do not use with storable pools. A permanently installed pool is constructed in or on the
ground or in a building such that it cannot be readily disassembled for storage. A storable pool is
constructed so that it may be readily disassembled for storage and reassembled to its original
integrity.

IMPORTANT SAFETY PRECAUTIONS (continued)
General Installation Information
The following information should be read carefully since it outlines the proper manner of care and operation for your
filter system. You can expect maximum efficiency and life from your filtration system by following these instructions and
taking the necessary preventative care.
• Have a trained pool professional perform all pressure tests.
• Do not connect the system to a high pressure or city water system.
• Trapped air in the system can create a hazardous condition. BE SURE to purge all air from the
system before operating or testing equipment.
• DO NOT pressure test with compressed air!
• Check local codes for restrictions on backwash to waste piping, separation tank requirements and
spent D.E. disposal requirements.
• DO NOT use more than the recommended amount of D.E. in your filter. To do so can cause a buildup
of D.E. and “bridging” between the elements which will plug the filter.
• Piping must conform to local/state plumbing and sanitary codes.
• Support piping independently to prevent strains on filter or valve.
• Fittings restrict flow; for best efficiency, use the fewest possible fittings.
• A check valve installed ahead of the filter inlet will prevent contaminants from draining back into the
pool.
• A check valve installed between the filter and heater will prevent hot water from backing up into the
filter and deforming the internal components.
• To allow recirculation during precoat, (if precoat pot is used), install a recirculation line with shut-off
between pad return line and pump suction.
• All wiring, grounding and bonding of associated equipment must meet local and/or National Electrical
Code standards.

Introduction
Quad D.E.™ Cartridge Style Filter Overview
The crystal clarity of D.E. with cartridge convenience
Diatomaceous earth (D.E.) filters have always been recognized for providing the cleanest pool water. And
cartridge filters are popular for their convenience and easy-cleaning features. Now, Pentair has found a way
to bring you the best of both.
The new Quad D.E. Cartridge Filter features four easily accessible and removable cartridges. When water
passes through these cartridges, microscopic impurities like dirt, algae, and some forms of bacteria are filtered
out, giving you water that really sparkles.
The four-cartridge design greatly increases the filter’s internal surface area, meaning much greater cleaning
capacity per cycle without an increase in canister size. And cleaning couldn’t be easier. In fact, you have
three options...backwash and recharge like a traditional D.E. filter, remove and rinse off the cartridges, or
simply remove the lid, leave the cartridges in place, open the drain plug, and rinse.
You’ll even save money – water flows through the Quad D.E. so efficiently that with the correct pump you
use less energy.
The highest water clarity with the lowest amount of fuss
The Quad D.E. combination of diatomaceous earth (D.E.) in a convenient cartridge design means better
performance and longer periods between cleanings. Because D.E. removes the tiniest of contaminants –
particles as small as five microns – you can count on clean, crystal-clear water for years to come.

The following general information describes how to install the Quad D.E.™ Filter.
Note: Before installing this product, read and follow all warning notices and instructions starting on page ii.
Installing the Quad D.E.™ Filter
Only a qualified service person should install the Quad D.E. Filter.
General Information
1. The filter should be mounted on a level concrete slab. Position the filter so that instructions, warnings and
the pressure gauge are visible to the operator. It also should be positioned 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. Allow sufficient clearance around the filter to permit visual verification that the clamp is properly installed
around the tank flanges, see Figure 1.
a. Tap the clamp with a mallet or similar tool to ensure uniform loading during clamp tightening.
4. Allow sufficient space above the filter to remove the filter lid for cleaning and servicing. This distance will
vary with the model of filter you are using. See Table 1 for the required vertical clearance.
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 personal injury as well as damage property.
5. 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 property.
CAUTION — The Pentair Quad D.E. filter has a different water flow pattern than all other Pentair D.E. filters. When
plumbing the filter with a backwash valve, one of the following valves, listed below, must be used. Failure
to use the correct backwash valve could damage the filter elements and void the warranty.
6. Your filter requires one of the following Pentair Water Pool and Spa accessories which must be purchased

for restrictions on backwash to waste piping, separation tank requirements and spent D.E. disposal
requirements.
8. Filter plumbing connections are provided with an o-ring seal. To avoid damage to the o-rings, use only a
silicone base lubricant on the o-rings. Do not use pipe joint compound, glue or solvent on the bulkhead
connections.
WARNING — THIS FILTER OPERATES UNDER HIGH PRESSURE.
Never subject this filter to pressure in excess of the maximum working pressure - even when conducting
hydrostatic pressure tests. Pressures above the maximum working p.s.i. pressure can cause the lid
to be blown off, which can result in severe injury, death or property damage.
9. The maximum working pressure of this filter is 50 psi. Never subject this filter to pressure in excess of this
amount - even when conducting hydrostatic pressure tests. Pressures above 50 psi 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, ensure 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 working 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.

Section 3
Filter Operation
This section describes how the Quad D.E.™ operates.
General Filter Information
WARNING — 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 High Flow™ manual 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.
1. This filter operates under pressure. When clamped properly and operated without air in the water system,
this filter will operate in a safe manner.
2. The maximum working pressure of this filter is 50 psi. Never subject this filter to pressure in excess of this
amount - even when conducting hydrostatic pressure tests. Pressures above 50 psi 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, ensure 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 working pressure will be stated on
each component of the system.
Ifdoubt existsastothe pressure towhichthe system will be subjected, install anASME approvedautomatic
Pressure Relief or Pressure Regulator in the circulation system for the lowest working pressure of any of
the components in the system.
3. The pressure gauge is the primary indicator of how the filter is operating. Maintain your pressure gauge
in good working order.
4. Never operate filter in excess of three (3) minutes without use of diatomaceous earth. Diatomaceous earth
is the substance that filters the water, the filter cloth merely supports the diatomaceous earth. Operating
without diatomaceous earth will damage filter elements and shorten filtering cycles.

Section 4
System Restart Instructions
This section describes how to restart the Quad D.E.™ filter system.
System Restart Instructions
WARNING — 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. Open the High Flow™ manual air relief valve until it snaps into the full open position (this only
requires a quarter turn counter clockwise). Opening this valve rapidly releases air trapped in the filter.
2. Stand clear of the filter tank, then start the pump.
3. Close the High Flow™ manual air relief valve after a steady stream of water appears.
4. The system is not working properly if:
a. A solid stream of water does not appear within 30 seconds after the pump's inlet basket fills with water.
b. The pressure gauge indicates pressure before water out-flow appears.
If either condition exists, shut off the pump immediately, open valves in the water return line to relieve
pressure, and clean the air relief valve; see Section 3; on page 5, FILTER OPERATION. If the problem
persists, call Customer Service at (800) 831-7133.

Preparing Diatomite
Your filter requires diatomaceous earth (D.E. or diatomite) for proper filtration and operation. Your filter
elements must be precoated with this material in order to protect their surfaces and provide the most efficient
filtering action. Refer to Table 2 for the proper quantity to use with your filter. We recommend the use of D.E.
which is sold and labeled for use with swimming pools and spas. These grades of D.E. typically have a
median particle size of 34 microns, which is ideal for most applications.
1. The Quad D.E. filters are listed with the appropriate amounts of diatomite to be used to precoat the filter
elements. A one (1) pound coffee can filled (level) with diatomite is equal to one half pound weight of
diatomaceous earth. Do not "pack" or compress diatomite into the coffee can.
2. Mix the required amount of diatomite with sufficient water

b. Multiport Rotary Valve.
After completing Steps 1 to 3 of this section; on page 10, perform the following steps:
(1) Position valve to BACKWASH setting.
(2) Open the High Flow™ manual air relief valve until it snaps into the full open position
(this only requires a quarter turn counter-clockwise). Opening this valve rapidly releases
air trapped in the filter.
(3) Stand clear of the filter tank, then start the pump.
(4) Close the High Flow™ manual air relief valve after a steady stream of water appears.
(5) When sight glass shows a clear flow of water, shut off pump.
(6) Position Multiport Rotary valve to CLOSED setting.
(7) Follow section 4.a – Slide Valve on page 10.
Cleaning Filter Elements
For a more thorough cleaning of the individual elements, perform the following steps:
1. Cleaning with water:
a. Using a garden hose, thoroughly flush off all contaminated diatomite from the filter element surfaces.
2. Cleaningwithmuriaticacid:
WARNING — Working with muriatic acid can be dangerous. When cleaning elements always wear rubber gloves
and eye protection. Add acid to water, do not add water to acid. Splashing or spilling acid can cause
severe personal injury and/or property damage.
a. A stiffening of the fabric caused by mineral deposits is usually referred to as "liming up". It usually is
due to deposits of either magnesium or calcium or both. Removal of these deposits may be
accomplished by soaking the filter elements in six (6) parts water to one (1) part hydrochloric acid
(muriatic acid).
b. Wear rubber gloves and eye protection when mixing the solution, and handling or rinsing the filter
elements.
c. Soak for at least four (4) hours in a plastic tub or pail.
d. Rinse filter elements thoroughly in tap water.

Cleaning the Internal Air Bleed Tube
1. Rinse the air bleed tube with water to clean away built-up debris. Normally, this is all that is necessary to
properly clean the tube.
Cleaning the High Flow™ Manual Air Relief Valve
1. Turn the pump off and shut off any automatic controls to ensure that the system is not inadvertently
started during servicing.
2. OPEN THE HIGH FLOW™ MANUAL AIR RELIEF VALVE UNTIL IT SNAPS INTO THE
FULL OPEN POSITION, THEN WAIT UNTIL ALL PRESSURE IS RELIEVED.
3. With the High Flow™ manual relief valve attached to the filter tank, pull out the locking tabs and remove
the valve stem and cover assembly with a counter-clockwise and lifting motion, see Figure 3.
4. Clean debris from the valve stem and body. Ensure that the filter tank's air passage is open by inserting a
5/16 in. drill bit through the valve body. Ensure that the o-rings are in good condition, properly positioned,
and lubricated with a silicone base lubricant.
5. Reinstall the valve stem and cover assembly with a downward and clockwise motion until it snaps into
position.

Troubleshooting
Use the following troubleshooting information to resolve possible problems with your Quad D.E.™ Filter.
WARNING — 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.
1. If you are not familiar with your pool filtering system and/or heater:
a. Do NOT attempt to adjust or service without consulting your dealer, or a qualified pool
technician.
b. Read the entire Installation & User’s Guide before attempting to use, service or adjust the
pool filtering system or heater.
Note: Turn off power to unit prior to attempting service or repair.

Correct any conditions in your filtration system
that allow air to enter the system.
a. Low water level in pool or spa - skimmer is
starving for water with pump running.
Add water to pool or spa.
b. Air bubbles or low water level in pump hair
and lint pot are caused by the following factors:
(1) Low water level.
(2) Cloggedskimmerbasket.
(3) Split suction cleaner hose.
(4) Leak in pump hair and lint pot lid.
(5) Leak in pump suction line.
c. Air bubbles coming out of water return lines into
pool or spa with pump running, see steps a-b,
above.

b. Refer to page 10, Cleaning Filter Elements
with muriatic acid for cleaning instructions.
CLOUD OF DIRT
A brief "cloud" of dirt may appear immediately when a. This is a characteristic of diatomite filters.
the filter starts.
SHORT FILTER RUNS
Until the water initially put into the pool has been
completely filtered, short filter runs are normal.
a. Plaster dust can be responsible for short
filterruns, requiringfrequentcleaning.
b. Elements may be loaded with oils, debris, etc.
Clean elements, refer to Cleaning Filter Elements

PRESSURE DROPS ON GAUGE
a. If pressure drops on gauge, shut off power to
pump and turn motor shaft with your fingers.
If it turns freely then the pump must be
disassembled and the impeller checked to see
if it is clogged. If it is not frozen or clogged then
there is an obstruction in the line between the
pool and the pump.
PRESSURE REMAINS HIGH
AFTER BACKWASH
a. If pressure remains high after backwash -
backwash filter again. If still high, treat for
conditions covered by LIMING-UP above.
MAINTAIN YOUR PRESSURE GAUGE
IN GOOD WORKING ORDER
The pressure gauge is an important part of the
filter system. It is your primary indicator of how
the system is operating.
a. Check the operation of your pressure gauge
in the following manner:
(1) The pressure gauge should go to zero (0)
when the system is turned off and pressure
is relieved.
(2) Thepressuregaugeshouldindicatepressure
when the system is operating.
(3) Thepressuregaugeshouldbereadableand
not damaged in any way.
(4) Replace the pressure gauge if it is not
meeting the requirements of items
(1) through (3) of this section.
DIATOMITE IS CONTINUOUSLY
ENTERING THE POOL
a. Inspect the elements for any tears or holes.
b. Inspect the internal air bleed sock for tears
andproperinstallation.
c. Inspect the elements and make sure the elements
arepositionedverticallyandproperlyseated
