IMPORTANT SAFETY PRECAUTIONS
Important Notice:
This guide provides installation and operation instructions for the Quad D.E.® Filter. Consult Pentair Water Pool and Spa® with any questions regarding this equipment.
Attention Installer: This guide contains important information about the installation, operation and safe use of this product. This information should be given to the owner and/or operator of this equipment after installation or left on or near the filter.
Attention User: This manual contains important information that will help you in operating and maintaining this filter. Please retain it for future reference.
WARNING —Before installing this product, read and follow all warning notices and instructions which are included. Failure to follow safety warnings and instructions can result in severe injury, death, or property damage. Call (800) 831-7133 for additional free copies of these instructions.
Consumer Information and Safety
The Quad D.E. Filters are designed and manufactured to provide many years of safe and reliable service when installed, operated and maintained according to the information in this manual and the installation codes referred to in later sections. Throughout the manual, safety warnings and cautions are identified by the “ 
“ symbol. Be sure to read and comply with all of the warnings and cautions.
WARNING —Do not operate the filter until you have read and understand clearly all the operating instructions and warning messages for all equipment that is a part of the pool circulating system. The following instructions are intended as a guide for initially operating the filter in a general pool installation, however each installation may have unique conditions where the starting procedure could be different. Failure to follow all operating instructions and warning messages can result in severe injury, death, or property damage.
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.

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.
