GENERAL
1) Pipe tap boss provided for optional influent pressure gauge.
2) SERVICING VALVE( Stop pump,close gate valve in suction&discharge before proceeding):
a) Set handle in filter position. b) Remove cover screws. c) Lift cover and key assembly out.
TO ASSEMBLE:
1) Place valve key so that wedge opening is at TOP port (handle in Filter psn.). Flat edge of cover screw lug
should align with flat edge of body screw lug.
2) Position cover O'Ring.
3) Secure assembly to body with cover screws. Tighten cover screws evenly and alternately. Do not over-
tighten.
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE CIRCULATING
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.

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 the 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 and 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.
Thismeans 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,
flushingthe previously trapped dirt and debris out the waste line. Once the filter is back-washed of dirt, set
control valve toRINSE position and run pump for about 1/2 to 1 minute, and then to filter, to resume normal
filtering.
NOTE: Turn pump off before changing valve position.

INSTALLATION

Only simple tools (screwdriver and wrenches), plus pipe sealant for plastic adapters, are required to install
andservice the filter.
1) The filter should be placed on a level concrete slab, very firm ground, or equivalent. Position the filter so
that the piping connections, control valve are convenient and accessible for operation and service.
2) Loading the sand media. Filter sand media is loaded through the top opening of the filter.
a) Loosen the clamp lock, remove the transparent lid.
b) Cover the diffuser with the block sand cover.
c) We recommend: add a half tank of water in the tank, then to fill with sand, so that we can protect
the bottom of the filter from the damage caused by excessive shock.
d) Add the right amount of sand, sand surface to smooth.
