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 broken or damaged fittings.
Refer to the diagrams for suggested valving.

all that is needed for complete filter draining. If desired
however, drain piping may be extended from the filter by
using an appropriate length of 1 1/2" pipe. Piping must
slope away from the filter so the tank can drain by gravity.
DO NOT use roll-flat type hose for drain piping.

recommendations for superchlorination and daily use.
STARTING THE FILTER
Close the filter drain and the vent valve. Caution: All suction
and discharge valves must be open when starting the
pump. Failure to do so could cause severe personal injury
and/or property damage.
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
Scoop 4 lbs. (1.8 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 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.
Stabilized forms of chlorine
Follow chemical manufacturer's
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 filter drain and open the vent valve (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.
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. Carefully pry the bump
cover from the head 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.
3.
Rotate the bump handle to the alternate position and align
the handle and the head anchor holes. Tap the pivot pin in
place.
4.
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 added
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 and take extreme caution when
handling cleaning agents as they can be harmful to the eyes,
skin and clothing. After cleaning, thoroughly flush all affected
parts with cold water.
