Perflex™ Extended Cycle Filtration System Troubleshooting (cont.) Problem Short cycles - even after proper Bump-Drain-Recharge. Probable Cause Contaminated (clogged) Flex-Tube braids caused by: 1. Natural accumulation of chemical deposits (accelerated if chemicals are fed through skimmer). 2. Running D.E. charge too long with excessive amount of live algae present in pool. 3. Operating filter without D.E. 4. Operating too long without D.E. after starting pump. D.E. must be added as soon as filter is full of water and pump is putting out a steady stream. IMPORTANT - Testing a new pool plumbing system without adding D.E. will cause this type of clogging. Remedy Clean tube nest (2 methods) 1. Detergent Cleaning: Remove tube nest and hose down with forceful stream of clean water. Soak tube nest in strong solution of laundry detergent (such as Cheer) and warm water. Hose down again. 2. Chemical Cleaning: This requires use of water and muriatic acid solution (or filter cleaner-type preparations) to chemically dissolve contaminates. Consult your pool dealer for chemical cleaning instructions. D.E. leaking to pool via the return lines. Opening or tear in one or more FlexTubes. Rip or hole in diaphragm gasket. Replace Flex-Tube. Replace gasket. Worn or loose fitting diaphragm gasket (chemicals fed through suction lines may shorten life of this part.) Replace gasket. Loose bolts on tube nest plates. Tighten bolts. Hard bumping. Caking of D.E. under tube sheet. Sometimes caused by accumulation of sun tan oils, hair, or floating particles that bind together in a clay-like form. Overloaded with D.E. Sometimes happens when last charge of dirty D.E. was not properly drained. Filter runs too long between bumping. Bump-Drain-Recharge more often and reduce the use of oils. Bump-Drain-Recharge with proper amount of D.E. Bump more frequently. D.E. leaking back to pool via skimmer or main drain. Very short cycles when vacuuming. Filter check valve worn or stuck open. Very dirty water. Clean and/or replace. Bump-Drain-Recharge more often. Presence of live, vigorously growing algae. Presence of alum or flocking agents which will clog filter. Add enough chlorine to control this growth - then vacuum. Vacuum so as to bypass filter. Avoid using flocking agents.

Troubleshooting (cont.)
Problem
Probable Cause
Remedy
Short cycles - even after proper
Bump-Drain-Recharge.
Contaminated (clogged) Flex-Tube
braids caused by:
1. Natural accumulation of chemical
deposits (accelerated if chemicals are
fed through skimmer).
2. Running D.E. charge too long with
excessive amount of live algae present
in pool.
3. Operating filter without D.E.
4. Operating too long without D.E. after
starting pump.
D.E. must be added as
soon as filter is full of water and pump
is putting out a steady stream.
IMPORTANT
- Testing a new pool
plumbing system without adding D.E.
will cause this type of clogging.
Clean tube nest (2 methods)
1. Detergent Cleaning: Remove tube
nest and hose down with forceful stream
of clean water.
Soak tube nest in strong
solution of laundry detergent (such as
Cheer) and warm water.
Hose down
again.
2. Chemical Cleaning: This requires use
of water and muriatic acid solution (or
filter cleaner-type preparations) to
chemically dissolve contaminates.
Consult your pool dealer for chemical
cleaning instructions.
Opening or tear in one or more Flex-
Tubes.
Replace Flex-Tube.
Rip or hole in diaphragm gasket.
Replace gasket.
Worn or loose fitting diaphragm gasket
(chemicals fed through suction lines
may shorten life of this part.)
Replace gasket.
D.E. leaking to pool via the return lines.
Loose bolts on tube nest plates.
Tighten bolts.
Caking of D.E. under tube sheet.
Sometimes caused by accumulation of
sun tan oils, hair, or floating particles
that bind together in a clay-like form.
Bump-Drain-Recharge more often and
reduce the use of oils.
Overloaded with D.E.
Sometimes
happens when last charge of dirty D.E.
was not properly drained.
Bump-Drain-Recharge with proper
amount of D.E.
Hard bumping.
Filter runs too long between bumping.
Bump more frequently.
D.E. leaking back to pool via skimmer
or main drain.
Filter check valve worn or stuck open.
Clean and/or replace.
Very dirty water.
Bump-Drain-Recharge more often.
Presence of live, vigorously growing
algae.
Add enough chlorine to control this
growth - then vacuum.
Very short cycles when vacuuming.
Presence of alum or flocking agents
which will clog filter.
Vacuum so as to bypass filter.
Avoid
using flocking agents.
