TROUBLESHOOTING 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.
