INSTALLATION
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. 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) Connect control valve to the filter using pipes with unions
b) Loosen the twelve nuts and washers and remove the filter coping.
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.

FUNCTIONS OF VALVE POSITIONS
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.

WARNING
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 overtighten.
FUNCTION
The filter uses s pecial filter san d to remove dirt p articles from poo l water. The filter sand is loaded i nto 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 p umped thr ough you r piping system
and is automati cally directed by the patented filter control valve to the top of the fi lter tank.As t he pool
water is pumped th rough the filter, d irt particles are trapped by the sand bed, and filtered out. T he
cleaned Po ol water is returned from the bottom of the filter tan k,through t he control valve and bac k to
the pool through the pipin g system. This entire sequence i s continuou s and automatic and provid es 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.
