User's Manual

RINSE—After backwashing, with pump off, set valve to
RINSE. Start pump and operate for about 1/2 to 1 minute. This
ensures that all dirty water from backwashing is rinsed out of
the filter to waste, preventing possible return to the pool. Stop
pump, set valve to FILTER and start pump for normal filtering.
WATER—To bypass filter for draining or lowering water level
and for vacuuming heavy debris directly to waste.
RECIRCULATE—Water is recirculated through the pool
system, bypassing the filter.
CLOSED—Shuts off flow from pump to filter.
VACUUMING—Vacuuming can be performed directly into the
filter. When vacuuming heavy debris loads, set valve to WASTE
position to bypass the filter and vacuum directly out to waste.
WINTERIZING
Completely drain tank by unscrewing drain cap at base of
filter tank. Leave cap off during winter.
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.
SERVICE & REPAIRS
Consult your local authorized Hayward dealer or service center.
No returns may be made directly to the factory without the
expressed written authorization of Hayward Pool Products, Inc.
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 Vari-Flo valve is set
on “Filter” position.

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.
