Assemble pump and pump mounting base (if supplied)
to the filter according to instructions packed with the
base.
Loading sand media. Filter sand media is loaded
through the top opening of the filter.
Remove the top diffuser from the internal diffuser
elbow pipe and place flexible, automatic air relief
tube to the side, out of the way, inside the tank.
Cap the internal diffuser elbow pipe with protection
cap provided to prevent sand from entering it.
It is good practice to fill tank approximately 1/2 way
with water to provide a cushioning effect when the
filter sand is poured in. This helps protect the
underdrain laterals from excessive shock. (Be sure
the drain cap is securely in place on drain pipe. Apply
wrench to flats on pipe when tightening cap.) Note:
Check to confirm all laterals are in the down
position before loading with sand. (See Figure A
on Page 2).
Carefully pour in correct amount and grade of filter
sand, as specified. Sand surface should be leveled
and should come to about the middle of the filter
tank. Use no more than the recommended amount of
sand.
Remove protection cap from internal diffuser elbow
pipe.
Replace diffuser on internal diffuser elbow pipe,
positioning automatic air relief tube through the hole
provided in the diffuser.
Place valve flange clamp around neck of tank. Do not
overtighten. Wipe filter flange clean.
Insert top closure dome (with flange O-ring in place)
into the tank neck. Place clamp around dome flange
and tank flange and tighten with screwdriver, tapping
around clamp with screwdriver handle to help seat
flange clamp.
Connect pump to control valve opening marked Port B
(middle). Make return to pool pipe connection to control
valve opening marked Port E (bottom) and complete
other necessary plumbing connections, suction lines to
pump, waste, etc.
Make electrical connections to pump per pump
instructions.
To prevent water leakage, be sure drain cap is securely
in place and all pipe connections are tight.
INITIAL START-UP OF FILTER
Be sure correct amount of filter sand media is in tank
and that all connections have been made and are
secure.
Set filter control valve to BACKWASH*. (To prevent
damage to control valve seal, always depress handle
before turning).
Prime and start pump according to pump instructions
(be sure all suction and return lines are open), allowing
the filter tank to fill with water. CAUTION: All suction
and discharge valves must be open when starting
the system. Failure to do so could cause severe
personal injury and/or property damage. Once water
flow is steady out the waste line, run the pump for at
least 2 minutes. This initial backwashing of the filter is
recommended to remove any impurities or fine sand
particles in the sand media.
Turn pump off and set valve to FILTER position (handle
UP and locked) and restart pump. Your filter is now
operating in the normal filter mode, filtering particles
from the pool water.
Adjust pool suction and return valves to achieve desired
flow. Check system and filter for water leaks and
tighten connections, bolts, nuts, as required.
Note the initial pressure gauge reading when the filter is
clean. (It will vary from pool to pool depending upon the
pump and general piping system.) As the filter removes
dirt and impurities from the pool water, the accumulation
in the filter will cause the pressure to rise and flow to
diminish. When the pressure gauge reading is 6-8 PSI
(0.41-0.55 BAR) higher than the initial “clean” pressure
you noted, it is time to backwash (clean) the filter (see
BACKWASH under Filter 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.
IMPORTANT: To prevent unnecessary strain on piping
system and valving, always shut off pump before
switching Filter Control Valve positions.
To prevent damage to the pump and filter and for proper
operation of the system, clean pump strainer and skimmer
baskets regularly.
FILTER CONTROL VALVE FUNCTIONS
FILTER and BACKWASH selections are provided for all
necessary operational functions.
FILTER —Set valve to FILTER for normal filtering. Also use
for vacuuming (handle in UP position).
BACKWASH —For pressure cleaning filter (handle in
DOWN position).
VACUUMING —Vacuuming can be performed directly into
the filter. Set valve in FILTER position.

*NOTE: For new concrete or gunite pools, or where there is a large amount of plaster dust or debris—start filter in FILTER position (not
BACKWASH) to prevent clogging of underdrain laterals.
