WINTERIZING
Completely drain tank by unscrewing drain cap at base of
filter tank. Leave cap off during winter. IMPORTANT: If
drain pipe starts to turn when unscrewing cap, place
wrench on flats on pipe to hold and prevent drain pipe
from unscrewing from the filter tank.
Depress Vari-Flo control valve handle and rotate so as to
set pointer on valve top between any two positions. This
will allow water to drain from the valve. Leave valve in
this “inactive” position.
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.
PROBLEM SOLVING LIST
REMEDY
LOW WATER FLOW
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.
SHORT FILTER CYCLES
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).
POOL WATER WON’T CLEAR UP
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 Vari-Flo valve is set on
“Filter” position.
