The following is a brief tutorial on the essentials of operating your Hayward EC-40 pool filter.
Starting the Filter System
After plugging in filter, it is time to add the D.E. (Diatomaceous Earth) by pouring it slowly into the skimmer while the filter is running. Add 3 lbs. for model EC-30, 4lbs for the Hayward EC-40 or 5 lbs. for the Hayward EC-50.
How Long Should the Filter Run Each Day?
Model EC-30 or EC-40 will filter 2,400 gallons per hour. Model EC50 will 3,000 gallons per hour. It is recommended that you turn over the water in your pool at least twice a day (refer to chart at bottom of page for your pools capacity).
Run filter more in hot weather or with heavy bather load.
What is Regeneration (Bumping)?
When return pressure (water flow) becomes weak or there is a surge in the pressure gauge reading, it is time to regenerate the filter powder. To do this unplug filter, then move handle at top of filter down slowly then up quickly. Repeat 3 times. Plug in filter and filtration will resume at or near original pressure. When bumping handle no longer extends filter cycle it may be time to backwash the filter. This is essential information for operating Your Hayward EC-40 pool filter.
What is Backwashing?
Backwashing completely clears filter of dirt, debris and filter powder by reversing the flow of water through the filter. To backwash, shut off filter and move bump handle at top of filter down slowly then up briskly. Repeat 8 times. Open drain (backwash valve) that is located at bottom of filter tank. Allow water to run until clear, close drain and follow instructions for starting filter.
Follow these steps that we’ve provided for operating Your Hayward EC-40 pool filter and you’ll be happy you purchased it.

Diatomaceous earth powder is an all-natural, porous powder derived from the tiny fossilized exoskeletons of algae-like water plants known as diatoms. When used in DE filter systems, diatomaceous earth powder provides a remarkable filtration media, trapping debris and contaminant particles ranging from leaves and dirt to bacteria and other micro-organisms.
