GUIDE
A. Short Cycle:
Time between cleanings will vary with each installa-
tion and between different areas of the country. The
following causes and remedies are for cycle times
shorter than normal for your area.
NOTICE: Some pool disinfectants may clog filter
media. To maximize media-life and filter cycle time,
closely follow disinfectant manufacturers instructions
when cleaning pool or filter.
1. Chlorine residual too low; maintain proper residual
(consult pool professional for recommendation).
2. Flow rate too high; restrict flow to rated capacity of
filter (see instruction decal on filter).
3. Filter too small; install larger filter or additional filter.
4. Unstable water; consult pool professional.
5. Filter element not cleaned properly or plugged with
algae, iron, calcium, etc. - see “Special Cleaning
Instructions”, Page 6.
6. Iron in water - use oversize filter running at a flow
rate of 3/8 to 1/2 GPM/sq. ft.; see cleaning instruc-
tions, Page 6.
7. Heavy or improper application of powdered chlo-
rine or chlorine pills using a binder; see “Special
Cleaning Instructions”, Page 6.
8. Algae in pool - Apply heavy dose of chlorine or al-
gaecide as recommended by pool manufacturer.
Continue until algae is controlled.
B. Low flow:
1. Element is plugged; see “Special Cleaning
Instructions”, Page 6.
2. Pipe blocked downstream from filter; remove ob-
struction.
3. Piping too small; replace with larger pipe (consult
dealer for recommendation).
4. Pump hair and lint trap is plugged - empty and
clean.
5. Pump impeller and diffuser worn - replace with new
parts. Consult pump owner’s manual for informa-
tion.
6. Pump too small for system - consult pool profes-
sional; if recommended, replace pump with larger
pump.
C. Pool Water Not Clear:
1. Chlorine dosage too low; maintain adequate
chlorine residual (consult pool professional for
recommendation).
2. Element cloth torn or punctured; replace element.
3. Filter too small, flow too low, or daily operating
time too short, giving inadequate turnover rate;
consult dealer to verify that equipment is properly
sized for your pool.
4. Pump too large - overpumping - reduce flow rate.
5. Filter installed backward - replumb.
D. Long Recovery Time After Heavy Usage:
1. Residual Chlorine level is too low - add chlorine.
2. Filter too small - replace with larger unit.
3. Pump too large - reduce flow rate.
E. Filter Bypasses Dirt:
To avoid severe injury or major prop-
erty damage, exactly follow instruc-
tions under “Disassembly” and
“Assembly” (Page 5)!
1. Air bleed tube and/or tube filter not in position.
Exactly follow instructions in “Filter
Disassembly/Assembly Procedure”, Page 5, and
reinstall correctly.
2. Element cloth torn or punctured; replace element.
3. Filter element is not seated properly in lower tank
half; follow instructions under “Filter
Disassembly/Reassembly”, Page 5, and reposition
properly.
4. Filter is plumbed backwards and element cloth is
ruptured - replumb properly and replace element.
5. Colloidal fines (very small suspended dirt particles)
are present and passing through element cover-
ing. Floc with alum, or if fines have already settled,
vacuum to waste.
