Troubleshooting Guide - STA-RITE System 2 Owner's Manual

1. Short Cycle Time:
NOTICE: Cycle Time will vary with each installation
and between different areas of the country. The
following causes and remedies are for cycle times
shorter than normal for your area.
A. Chlorine residual too low; maintain proper
residual (consult pool professional for
recommendation).
B. Flow rate too high; restrict flow to rated capacity
of filter (see instruction plate on filter or
specifications on Page 4).
C. Filter is too small; install an additional filter.
D. Improper/insufficient precoat; see precoat
instructions (Page 6).
E. Filter module is dirty or plugged; thoroughly
clean the filter (see No. 4, "Plugged Module
Cloth", and "Module Cleaning Procedure", Page
8).
F. Too much DE; check for clogged filter module.
G. Water is chemically out of balance; consult pool
professional.
H. Algae in the pool. Apply heavy dose of chlorine
or algicide as recommended by the pool
manufacturer.
2. Low Flow/High Pressure:
A. Elements plugged; clean filter thoroughly (see
Page 8).
B. Pipe blocked downstream from filter; remove
obstruction.
C. Piping too small; use larger pipe (consult dealer
for sizing).
D. Filter area too small; install an auxiliary filter
(consult dealer for recommendation).
E. Outlet port check valve obstructed (if applicable);
remove obstruction to allow valve to open.
3. Low Flow/Low Pressure:
A. Pump too small; consult dealer for
recommendations.
B. Plugged pump or plugged hair and lint trap;
clean thoroughly.
4. Plugged Module Cloth:
NOTICE: The pleated filter material may look matted
after use. However, as long as the DE adheres to the
pleated cloth, the filter is operating properly.
A. Insufficient precoat; see precoat instructions
(Page 6).
B. Insufficient cleaning; follow cleaning instructions

closely and clean thoroughly (see Page 8).
C. Water is chemically out of balance; consult pool

D. Excessive air in filter; non-precoated areas may
plug. Vent air from tank and check for pump
suction pipe leaks. Clean air bleed filter in grid
assembly with a hose and soft flow nozzle.
E. Filter is too small. Install an additional filter.
F. Pool water contains iron. See "Special Cleaning
Instructions", Page 8.
G. Algae in pool. Apply heavy dose of chlorine or
algicide as recommended by the pool
manufacturer.
H. Use of incorrect chemicals with PHMB sanitizers.
Replace filter module.
I. Not enough D.E. precoat. Filter requires 6 lbs.
(2.7 kg.) of D.E. for adequate precoat.
5. Pool Water Not Clean:
A. Chlorine residual too low; maintain adequate
chlorine residual (consult pool service technician
for recommendation).
B. Broken filter module passing DE into pool;
replace defective module.
C. Insufficient or improper precoat; follow precoating
instructions and use recommended amount of
DE (see Page 6).
D. Inadequate turnover rate; consult dealer to verify
that equipment is properly sized for your pool.
E. Pump is too large and is overpumping. Reduce
the flow rate.
F. The filter is installed backwards. Reinstall it
correctly.
G. Pool water contains iron. See "Special Cleaning
Instructions", Page 8.
H. Heavy or improper application of powdered
chlorine tablets using a binder. See "Special
Cleaning Instructions", Page 8.
I. Algae in the pool. Apply heavy dose of chlorine
or algicide as recommended by the pool
manufacturer.
6. Pool Accessories Stop Working:
A. Clean filter and observe performance of
accessories.
B. If accessories perform better after filter has been
cleaned, use a shorter cleaning cycle for the filter
(that is, clean the filter after a pressure rise of
less than 10 PSI).
