USE ONLY HAYWARD GENUINE REPLACEMENT PARTS 4
The Hayward-Perflex filters are high performance swimming pool filters. As a system the EC65A has an output rating of 3,240 gallons (12.2 Kl) per
hour, while the EC75A has an output rating of 4800 gallons (18.0 Kl) per hour. Manufactured from durable, corrosion-proof materials, the filter can
be combined with a pump and combined on a strong, molded mounting base. The systems are designed for continuous operation, for installation
below, the pool water line and up to 2 feet above the water line. They 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.
Hayward Pool Pumps are non-corrosive, centrifugal pumps with pressure, flow, and safety features specifically designed for swimming pool
service. They are driven by a heavy duty motors, which are electrically isolated and insulated from the pool water. Output pressure and flow are
tuned to the filter, resulting in a perfectly balanced, non-corrosive system. Select a pump with an output rating between 30 and 100 GPM (115
to 380 LPM)
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.
2. For best pump performance, the system should be located below the swimming pool water line or up to 2 feet above the water line. If
located above the water line make sure to select a self-priming pump such as a Super Pump
®
, Super II™, MaxFlo or TriStar™. 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.
3. Position the system so that the filter tank can drain by gravity.
PLUMBING & INSTALLATION
1. To facilitate servicing of the filter system and to allow for indoor storage during the winter months, installing union connections at the
suction and outlet ports is recommended.
2. Use 1-1/4" or 1-1/2" I.D. flexible plastic pipe, or hose, joined with insert fittings and stainless steel clamps.
3. 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.
4. Refer to the diagram for suggested valving. Ball-type valves are recommended where needed.
5. Tighten pump base mounting bolts, if loose.
6. Securely
hand tighten
the union nut between the filter and pump.
7. Connect the pool suction plumbing between the skimmer, pool outlet, and the pump.
8. Connect the pool return (inlet) plumbing
9. 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.
10. A filter 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 appropriate length of 1-1/2"
pipe. Piping must slope away from the filter so the tank can drain by gravity.
11. All electrical connections should be made in accordance with applicable electrical
codes.
12. Check for joint leaks before operating system.
13. Refer to pump instruction booklet for pump information.
BEFORE STARTING THE FILTER
1. Obtain a supply of operating chemicals, D.E., and a pool test kit.
Use only the swimming pool grades of D.E., such as:
CELATOM

A trademark of EP Minerals
DICALITE
®

DE Filter media Local Pool Supply
2. Superchlorinate the pool water by adding unstabilized granular or liquid chlorine. Stabilized forms of chlorine are recommended
for normal daily use after the initial clean-up of the water. Follow chemical manufacturer's recommendations for superchlorination
and daily use.
