PUMP SELECTION

To power your Perflex filter, select a continuous duty pump

designed for swimming pool service.

The pump mounting

bracket and hardware furnished with 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 65

GPM (114-246 LPM).

Since 40 GPM (150 LPM) is the desired

maximum filter flow, a flow controller (part number ECX1055) is

furnished with each unit for use with pumps rated between

40

and

65

GPM

(150-246

LPM).

Install

the

flow

controller in the filter body as illustrated with an elbow adapter,

union connector, or adapter.

The adapter both secures the

controller in its proper

position, and completes

the hydraulic balance of

the system.

FILTER LOCATION

Since

plumbing fittings

offer a resistance to

water flow, locate the

filter as close to the

swimming

pool

as

practical.

Keep the

number of fittings to a minimum.

Select a well-drained area,

one that will not flood when it rains.

Set the filter on a

level

platform or base.

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 out

let.

Instructions for changing the handle position are covered

later.

Position the filter so the tank can drain by gravity.

PLUMBING

Use 1-1/4

”

or 1-1/2

”

I.D. flexible plastic pipe, or hose, joined

with insert fittings and stainless steel clamps.

If a rigid pipe

is used, be sure to provide unions for easy servicing.

Ball-style control valves are recommended.

All plumbing connections on the EC40 filter are 1-1/2

”

N.P.T.

When making connections to the filter, use plastic male-end

adapters.

Apply three turns of Teflon tape or plastic pipe

sealant to the male threads.

MODEL EC40 SERIES

The Perflex Model EC40 is a high performance swimming pool filter with a filtration rating of 2,400 gallons

(9.1 KL) per hour.

Manufactured from durable, corrosion-proof materials, it is designed for continuous

operation, for installation above or below the pool water line, for fresh or salt water swimming pools.

The

EC40 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 its dirt holding capacity has been reached.

Through 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.
