The filter uses special filter sand to remove dirt particles from pool water. The filter sand
is loaded into the filter tank and functions as a permanent dirt removing media. When
the control valve is in the FILTER position, the pool water which contains suspended dirt
particles, is pumped through your piping system and is automatically directed by the
patented filter control valve to the top of the filter tank. As the pool water is pumped
through the filter, dirt particles are trapped by the sand bed, and filtered out. The
cleaned pool water is returned from the bottom of the filter tank, through the control
valve and back to the pool through the piping system. This entire sequence is
continuous and automatic. It provides for total recirculation of pool water through your
filter and piping system.
After a period of time, the accumulated dirt in the filter causes a resistance to flow, and the flow diminishes. This means it is
time to clean your filter. With the control valve in the BACKWASH position, the water flow is automatically reversed through
the filter so that it is directed to the bottom of the tank, up through the sand, flushing the previously trapped dirt and debris
out the waste line. Once the filter is back-washed of dirt, set control valve to RINSE position and run pump for about 1/2 to 1
minute, and then set the control valve in the FILTER position, to resume normal filtering.
NOTE: Turn pump off before changing valve position.
Only simple tools (screwdriver and wrenches), plus pipe sealant for plastic adapters, are required to install and service the filter.
1) The filter should be placed on a level concrete slab, very firm ground, or equivalent. The filter should be placed
2) Loading the sand media. Filter sand media is loaded through the top opening of the filter.
a) Loosen the flange clamp and remove filter control valve (if previously installed).
b) Cap internal pipe with plastic cap to prevent sand from entering it.
c) We recommend filling the tank approximately 1/2 way with water to provide a cushion effect when the filter sand is poured
in. This helps protect the under-drain laterals from excessive shock.
d) Carefully pour in correct amount and grade of filter sand. (Be sure center pipe remains centered in opening.) Sand
surface should be leveled and should come to about the middle of the filter tank. Remove plastic cap from internal pipe.
3) Assemble filter control valve into the filter tank.
a) Insert filter control valve (with O'ring in place) into the tank neck, taking care that the center pipe slips into the
hole in the bottom of the valve.
b) Place two plastic clamps around valve flange and tank flange and tighten just enough so that the valve may
be rotated on tank for final positioning.
c) Carefully screw pressure gauge (with O'ring in place) into tapped hole in valve body. Do not over-tighten.
d) Connect pump to control valve opening marked PUMP. After connections are made, tighten valve flange
clamps with screwdriver, tapping around clamp with screwdriver handle to help seat valve flange clamp.
4) Make return to pool pipe connection to control valve opening marked RETURN and complete other necessary
plumbing connections, suction lines to pump, waste, etc.
5) Make electrical connections to pump per pump instructions.
6) To prevent water leakage, make sure all pipe connections are tight.
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE CIRCULATING SYSTEM (e.g., CLAMP, PUMP,
FILTER, VALVES, ETC.) IS SERVICED, AIR CAN ENTER THE SYSTEM AND BECOME PRESSURIZED . PRESSURIZED AIR CAN
CAUSE THE LID OR VALVE TO BE BLOWN OFF WHICH CAN RESULT IN SEVERE INJURY, DEATH, OR PROPERTY
DAMAGE.
TURN PUMP OFF BEFORE CHANGING VALVE POSITION.
TO PREVENT DAMAGE TO THE PUMP AND FOR PROPER OPERATION OF THE SYSTEM, CLEAN PUMP STRAINER AND
SKIMMER BASKETS REGULARLY.
DO NOT UNSCREW SCREWS OF FLANGE CLAMP WHILE PUMP IS RUNNING.
UNDER LOW TEMPERATURE SHUT OFF CONDITION, IT IS STRONGLY RECOMMEND TO TURN TO WINTERISE POSITION
AND DISCHARGE ALL THE WATER INSIDE FILTER THROUGH THE BOTTOM DRAIN.
