IS40AB-98
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.
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
1.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.
2.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 outlet. Instructions for changing the handle position are covered later.
3.Position the filter so the tank can drain by gravity.
PLUMBING
1.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.
2.Ball-style control valves are recommended.
3.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.
