iii 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.
iv 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.
1 Section 1 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.
2 General Features • Four large-capacity cartridges provide maximum filter surface area for greater dirt-trapping capacity and longer periods between cleanings. • Unique internal flow path ensures optimum filtration and backwashing efficiency. • Chemical resistant, fiberglass reinforced polypropylene tank for exceptional strength and long life. • Tension Control™ clamp for secure closure. • 2” plumbing connections for simple and secure maximum flow.
3 Section 2 Installation 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.
4 General Information, cont.’d. 7. Make all plumbing connections in accordance with local plumbing and building codes. Check local codes 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.
5 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.
6 Clamp Installation These instructions MUST BE FOLLOWED EXACTLY to prevent the lid from blowing off during system restart or later operation. 1. Perform the following steps before working on any part of the circulating system, e.g., clamp, pump, filter, valve(s), etc. a. Turn the pump off and shut off any automatic controls to ensure that the system is not inadvertently started during servicing. b.
7 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.
8 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.
9 Section 5 Maintenance Cleaning the Quad D.E.® Filter Manually 1. Turn the pump off, shut off any automatic controls to ensure that the system is not inadvertently started during servicing. 2. Automatic skimmer should have Vari-Flo trimmer valve set to 100% skimmer. This will close off the main drain line. If there is a separate skimmer line and main drain line plumbed to the pump, close the main drain valve. 3.
10 Replacing Filter Cartridge Style Elements Filter cartridge style element life will vary with pool conditions such as bather load, wind, dust, etc. You can expect an average cartridge life of 3 years under normal conditions. 1. To replace cartridge style elements follow steps in Section 5; on page 9, CLEANING FILTER MANUALLY, eliminating step 8. Cleaning your Filter using a System with a Separation Tank 1. Before working on any part of the circulating system, clamp, pump, filter, valve(s), etc.
11 Cleaning your Filter using a System with a Separation Tank, cont’d. b. Multiport Rotary Valve. After completing Steps 1 to 3 of this section; on page 10, perform the following steps: (1) Position the valve to the 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.
12 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.
