STARTING THE FILTER
Close the filter drain and the vent valve.
CAUTION: Separation Hazard. Failure to open all suction and discharge valves when starting the pump could cause
severe personal injury and/or property damage. To avoid open all suction and discharge valves.
Prime and start the pump following the manufacturer's instructions. Air trapped in the system will automatically vent to
the pool. When there is a steady flow of water returning to the pool, the filter is ready for precoating. DO NOT operate
the filter for more than one minute without the precoat charge.
PRECOATING
For the EC65A Scoop 6 lbs. (2.7 kgs.) of diatomite into the system through the skimmer as fast as the plumbing will take it.
For the EC75A Scoop 7 lbs. (3.2 kgs.) of diatomite into the system through the skimmer as fast as the plumbing will take it.
Note and record the pressure gauge reading after the diatomite has been added. This is the
"precoat pressure."
FILTERING
Filtration starts as soon as the filter has been precoated. As the filter removes dirt from the pool water, the accumulated dirt causes a
resistance to flow. As a result, the gauge pressure will rise and the flow will decrease. When the pressure rises 7-10 psi (.49-.70 Bar)
above the precoat pressure, regenerate the filter.
REGENERATION (Extending the Cycle)
Stop the pump. Move the bump handle down slowly, then up briskly. Repeat 3 times. Restart the pump and filtration will resume at
near the original flow and pressure.
After each regeneration, and until the filter is cleaned, there may be a slight increase in the starting pressure. This is the result of dirt
accumulating within the filter and is completely normal.
CLEANING
Cleaning is recommended when the gauge pressure rises more than 10 psi (.70 Bar) in less than a 24 hour period or when cloudy water
returns to the pool for more than 30 seconds after regeneration. To clean, first stop the pump; then move the bump handle down
slowly, then up briskly. Repeat 8 times. Open the vent valve (under bump cover), open the filter drain (Note: if the filter is installed
below the pool water line, close the suction and return valves) and allow water and-dirt-to-empty completely.
After the filter has drained, and with the drain still open, run the pump for a few seconds to flush out any dirt remaining in the bottom of
the filter. (Note: If the filter is installed below the pool water line, opening the
suction valve for a few seconds with the pump off will
adequately flush the unit.)
Close the filter drain and the vent valve. Open the suction and return valves (when used). Start the pump and let the filter fill with
water and repeat the CLEANING procedure. This completes the cleaning phase. The filter is now ready for recharging. Proceed as in
STARTING THE FILTER and PRECOATING.
VACUUMING
Vacuuming can be performed directly into the filter whenever needed. For fastest results, regenerate the filter before and after each
vacuuming operation.
TO CHANGE BUMP HANDLE POSITION
1. Remove the bump handle grip. Push in tab at base of handle. Carefully pry the bump cover from the retaining groove and slide the
cover off the handle.
2. Using a drift (or 10 penny nail), tap the pivot pin out of the filter head anchor point, freeing the end of the handle.
Rotate the bump handle to the alternate position and align the handle and the head anchor holes. Tap the pivot pin in place.
3. Reinstall the bump cover and grip.
PREVENTIVE MAINTENANCE
While Perflex filters are basically resistant to the difficulties often encountered as a result of chemical build-up in swimming pools, it is
important to keep in mind that the mineral content in a pool increases every day as a result of the chemicals and the normal water
evaporation process. If the concentration of minerals is allowed to get too high, the minerals will form deposits on the Flex-Tubes inside
the filter, and will eventually result in shortened filter cycles. To guard against this, a yearly chemical cleaning (soaking) of the Flex-Tube
assembly is suggested. Use commercially available 20% muriatic acid added to water in 1 to 1 ratio; or use other commercial filter
element cleaner mixed according to the package instructions. Use a plastic container.
CAUTION: Chemical Hazard –Chemicals can cause personal or property damage, to avoid use personal
protective gear when handeling.
After cleaning, thoroughly flush all affected parts with cold water. Always wear gloves and eye protection when handling cleaning
agents.
WINTERIZING
In areas where sub-freezing temperatures can be expected, the filter should be drained and removed from its operating location and stored
indoors. Prior to removal, cycle the filter as described under CLEANING.
