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.
WARNING
!
!
TO PREVENT DAMAGE TO THE PUMP AND FOR PROPER OPERATION OF THE SYSTEM,
CLEAN PUMP STRAINER AND SKIMMER BASKETS REGULARLY.

FUNCTIONS OF VALVE POSITIONS
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.

FUNCTION
The filter uses special filter sand to remove dirt particles from pool water. The filter sand is loaded into the filter tank
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. 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 to filter, to
resume normal filtering.
and
NOTE: Turn pump off before changing valve position.
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. 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) Place tow O'ring on the side of the filter tank and Connect control valve to the filter using pipes with unions and
glues.(see the fig on page4).
b) Loosen the Ring lock Nut by 2 handles and remove the valve.
c) We recommend filling tank approximately 1/3 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. Sand surface should be leveled and should come to about
the middle of the filter tank.
