3.
Loading sand media. Filter sand media is loaded through the
top opening of the lter.
a.
Loosen ange clamp and remove Filter Control Valve (if
previously installed).
b.
Cap internal pipe with plastic cap to prevent sand from
entering it. Be sure pipe is securely in place in bottom
underdrain hub.
c.
We recommend
with water to provide a cushioning e ect when the
lter sand is poured in. This helps protect the
under-drain laterals from excessive shock. (Be sure the
winter drain cap is securely in place on drain pipe.) Note:
Please check to con rm all laterals are in the down
position before loading with sand. See gure A.
d.
Slowly pour in correct amount and grade of lter sand, as
speci ed. (Be sure center pipe remains centered in
opening.) Sand surface should be leveled and should
come to about the middle of the lter tank. Remove
plastic cap from internal pipe.
4.
Assemble Filter Control Valve to lter tank.
Place stainless steel valve ange clamp around neck of
a.
tank. Do not tighten. Wipe lter ange clean.
Insert Filter Control Valve (with valve/ ange o-ring in
b.
place) into the tank neck, taking care that the center pipe
slips into the hole in the bottom of the valve. Place clamp
around valve ange and tank ange and tighten just
enough so that the valve may be rotated on tank for nal
positioning.
Carefully screw pressure gauge, with pipe tape, into 1/4
c.
tapped hole in valve body. Do not overtighten.
d.
Connect pump to control valve opening marked PUMP
according to instructions. After connections are made,
tighten valve ange clamp with screwdriver, tapping
around clamp with screwdriver handle to help seat valve
ange clamp.
5.
Make return to pool pipe connection to control valve
opening marked RETURN and complete other necessary
plumbing connections, suction lines to pump, waste, etc.
6.
Make electrical connections to pump per pump instructions.
7.
To prevent water leakage, be sure winter drain cap is securely
in place and all pipe connections are tight.
INITIAL START UP OF FILTER
1.
Be sure correct amount of lter sand media is in tank and
that all connections have been made and are secure.
2.
Depress Vari-Flo control valve handle and rotate to
BACKWASH position. (To prevent damage to control valve
seal, always depress handle before turning.)
3.
Prime and start pump according to pump instructions (be
sure all suction and return lines are open), allowing the lter
tank to ll with water. Once water ow is steady out the
waste line, run the pump for at least 2 minutes. The initial
backwashing of the lter is recommended to remove any
impurities or ne sand particles in the sand media.

4.
Turn pump o and set valve to RINSE position. Start pump and
operate until water in sight glass is clear - about 1/2 to 1
minute. Turn pump o and set valve to FILTER position and
restart pump. Your lter is now operating in the normal lter
mode, ltering particles from the pool water.
5.
Adjust pool suction and return valves to achieve desired ow.
Check system and
connections, bolts, nuts, as required.
6.
Note the initial pressure gauge reading when the lter is clean.
(It will vary from pool to pool depending upon the pump and
general piping system.) As the
impurities from the pool water, the accumulation in the lter
will cause the pressure to rise and ow to diminish. When the
pressure gauge reading is 8-10 Ibs. (4-6 BAR) higher than the
initial "clean" pressure you noted, it is time to backwash (clean)
the
lter (see BACKWASH under Filter and Control Valve
Functions).
NOTE: During initial clean-up of the pool water it may be necessary
to backwash frequently due to the unusually heavy initial dirt
load in the water.
CAUTION: To prevent unnecessary strain on piping system and
valving, always shut o pump before switching Filter Control
Valve Functions positions.
To prevent damage to the pump and lter and for proper
operation of the system, clean pump strainer and skimmer
baskets regularly.
FILTER AND CONTROL VALVE FUNCTIONS
FILTER - Set valve to FILTER for normal ltering. Also use regular
vacuuming.
BACKWASH - For cleaning lter. When lter pressure gauge rises
8-10 Ibs. (4-6 BAR) above start-up (clean pressure): Stop the
pump, set valve to BACKWASH. Start pump and backwash until
waste water is clear. Approximately 2 minutes or less
depending on dirt accumulation. Proceed to RINSE.
RINSE - After backwashing, with pump o , set valve to RINSE. Start
pump and operated for about 1/2 to 1 minute. This assures
that all dirty water from backwashing is rinsed out of the lter
to waste, preventing possible return to the pool. Stop pump,
set valve to FILTER, and start pump for normal ltering.
WASTE - To bypass lter for draining or lowering water level and for
vacuuming heavy debris directly to waste.
RECIRCULATE - Water is recirculated through the pool system
by-passing the lter.
CLOSED - Shuts o
ow from pump to lter.
VACUUMING - Vacuuming can be performed directly into the lter.
When vacuuming heavy debris loads, set valve to WASTE
position to bypass the lter and vacuum directly out to waste.
*NOTE: For new concrete or gunite pools, or where there is a large
amount of plaster dust or debris - start lter in FILTER position (not
BACKWASH) to prevent clogging of underdrain laterals.
