Hayward Perflex® Extended-Cycle Models: EC65A EC75A - Page 4

Page 4 of 12 IS65ING Rev A WARNING - To avoid dangerous or fatal electrical shock, turn OFF power to motor before working on electrical connections. WARNING - Failure to bond pump to pool structure will increase risk for electrocution and could result in injury or death. To reduce the risk of electric shock, see installation instructions and consult a professional electrician on how to bond pump. Also, contact a licensed electrician for information on local electrical codes for bonding requirements. The Hayward-Perflex is a high performance swimming pool filter. The EC65AC filter it has an output rating of 3,240 gallons (12.2 KL) per hour. The EC75AC filter it has an output rating of 4800 gallons (18.0 KL) per hour Manufactured from durable, corrosion-proof materials, the filter can be combined on a strong, molded mounting base. The filters are designed for continuous operation, for installation up to 2 feet above, the pool water line. It may be used on fresh or salt water swimming pools. The Perflex filter uses diatomite filter powder (commonly called D.E.). D.E. is the most efficient dirt remover known. It is normally fed into the system through the skimmer when the filter is initially started; then drained from the filter when it can no longer efficiently remove dirt from the water. Through the Perflex's exclusive "BUMP" action, the D.E. is periodically regenerated and the filter cycle extended without changing the powder. When the filter powder is totally used, the "BUMP" action makes it possible to drain the used diatomite without backwashing or dismantling the filter. PUMP SELECTION To power your Perflex filter, select a continuous duty pump designed for swimming pool service. The pump mounting bracket (EC65BLP) and hardware purchased separately for the filter will readily accept most units. It is important to determine whether the pump will be located above or below the normal pool water line. If the pump is going above the water line, a self-priming centrifugal pump must be used. Self-priming pumps can lift water from a lower level and prime automatically. There is another type of pump simply called the centrifugal. Unlike self-priming centrifugals which can lift water from a lower level, a centrifugal must be located below the water line for dependable priming. Select a pump with an output rating of between 30 and 100 GPM (114-380 LPM). 3. Set the mounting platform level. Keep the filter bump handle, drain outlet, and pressure gauge accessible for convenient operation. There is an alternate bump handle location on the other side of the filter outlet. Instructions for changing the handle position are covered later. 4. Position the system so that the filter tank can drain by gravity. PLUMBING & INSTALLATION 1. Use 1-1/2" I.D. flexible plastic pipe, or hose, joined with insert fittings and stainless steel clamps. If rigid return piping is used, installation of a piping union is recommended for ease of future servicing. 2. All plumbing connections on the system are 1-1/2" N.P.T. When making connections, use plastic male-end adapters. Apply three turns of Teflon tape or plastic pipe sealant compatible with ABS to the male threads. Screw the fitting into the thread hand tight; then, using a wrench, tighten one more full turn. Additional tightening is unnecessary-and-could result in damage to components. 3. Tighten pump base mounting bolts, if loose. 4. Securely hand tighten the union nut between the filter and pump. 5. Connect the pool suction plumbing between the skimmer, pool outlet, and the pump. 6. Connect the pool return (inlet) plumbing 7. If the pressure gauge is not installed, apply Teflon tape to the gauge threads, and carefully screw the gauge into the threaded hole in the side of the filter body. 8. A drain plug, with gasket, is furnished with each filter and is all that is needed for complete filter draining. If desired however, drain piping may be extended from the filter by using the optional Drain Valve Kit (Model SP0723) and an SYSTEM LOCATION 1. Though the system is designed for outdoor use, it is advisable to protect electrical components from the weather. Select a well-drained area, one that will not flood when it rains. appropriate length of 1-1/2" pipe. Piping must slope away from the filter so the tank can drain by gravity. 9. All electrical connections should be made in accordance with applicable electrical codes. 2. For best pump performance, locate the system above the pool water line, a Super Pump®, Super II™ pump, Max-Flo or TriStar™ pump is required and can be raised two feet above 10. Check for joint leaks before operating system. 11. Refer to pump instruction booklet for pump information. the water line.
