TROUBLESHOOTING GUIDE
1. Short Cycle Time:
NOTICE: Cycle Time will vary with each installation and be- tween 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 (con- sult 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 5).
E.Filter module is dirty or plugged; thoroughly clean the fil- ter (see No. 4, “Plugged Module Cloth”, and “Module Cleaning Procedure", Page 8).
F.Too much DE; check for clogged filter module.
C.Water is chemically out of balance; consult pool professional.
D.Excessive air in filter;
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 algaecide as recommended by the pool manufacturer.
H.Use of incorrect chemicals with PHMB sanitizers. Replace filter module.
I.Not enough D.E. precoat. See precoat instructions (Page 4).
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).
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 defec- tive module.
C.Insufficient or improper precoat; follow precoating instruc- tions and use recommended amount of DE (see Page 4).
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 algi- cide 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).
