PROBLEM SOLVING LIST
LOW WATER FLOW
SHORT FILTER CYCLES
POOL WATER WON’T CLEAR UP
Check skimmer and pump
strainer baskets for debris.
Check for restrictions in
intake and discharge lines.
Check for air leak in intake
line (indicated by bubbles
returning to pool).
Backwash filter.
Check for algae in pool and
superchlorinate as required.
Be sure chlorine and pH
levels are in proper range
(adjust as required).
Check surface of filter sand
for crusting or caking
(remove 1
”
of sand if
necessary).
Check chlorine, pH and total
alkalinity levels and adjust
as required.
Be sure flow rate through
filter is sufficient.
Operate filter for longer periods.
Be sure control valve is set
on “Filter” position.

WINTERIZING
Completely drain tank by unscrewing drain cap at base of
filter tank. Leave cap off during winter. Drain filter control
valve.
Drain and winterize pump according to pump instructions.
PLEASE REALIZE . . .
Pure, clear swimming pool water is a combination of two
factors—adequate filtration and proper water chemistry
balance. One without the other will not give the clean water
you desire.
Your filter system is designed for continuous operation.
However, this is not necessary for most swimming pools.
You can determine your filter operation schedule based on
your pool size and usage. Be sure to operate your filtration

system long enough each day to obtain at least one
complete turnover of your pool water.
To properly sanitize your pool, maintain a free chlorine level
of 1 to 3 ppm and a pH range of 7.2 to 7.6. Insufficient
chlorine or an out of balance pH level will permit algae and
bacteria to grow in your pool and make it difficult for your
filter to properly clean the pool water.
