Hayward Perflex EC50C Series Owner's Manual page 4

The Hayward-Perflex is a high performance swimming pool filter. As a system it has an output rating of 3,000 gallons (11 Kl) per hour. Manufactured from
durable, corrosion-proof materials, the filter and pump are combined on a strong, molded mounting base. The systems are designed for continuous operation, for
installation below, 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.
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.
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 MUST be located below the swimming pool water line. 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 ® A trademark of EP Minerals
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.
INITIAL SET-UP (WITH PLASTIC-TYPE CLAMP)
1. Always turn off pump and relieve tank pressure by opening Air Relief Valve before
loosening Center Clamp or servicing filter.
2. To re-assemble Clamp on filter, make sure Clamp is located and centered properly
over the filter flange. If Clamp is tight, tap Clamp with rubber mallet or block of wood
to help seat it.
Slide a Washer over each Bolt followed by a Spacer Tube. Insert Bolt assembly
through both Clamp Halves. Slide on a Washer, secure with Hex Nut and hand tighten.
Repeat on other side of Clamp.
Alternately tighten both Bolt assemblies using a wrench and socket (1/2" drive).
Alternately tighten until Spacer Tube is engaged (approx. 100 in-lbs). Finally, tighten
3. To re-start system, open all in-line valves. Open Air Relief Valve before starting pump. Stand clear of filter and prime and start the pump per
the manufacturer's instructions. When a steady stream of water emerges from the Air relief Valve, close Air Relief Valve.
USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
1 / to 1 / turn to secure (approx. 100 in-lbs).
