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).

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, locate the system above the
pool water line, a Super Pump
TriStar™ pump is required and can be raised two feet above
the water line.
®
, Super II™ pump, Max-Flo or
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
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.
10. Check for joint leaks before operating system.
11. Refer to pump instruction booklet for pump information.
