* Install filtration system including pump,filter tank and multiport valve.
* The filter system should be installed as close as possibie to the swimming pool and preferably at a level
of 0.50 metres below the surface of the water in the swimming pool. Make sure there is drainage
available at the place where the filter is to be installed.
* PUMP
1) Only qualified,licensed personnel should install pump and wiring.
2) Electrical Contractors Please Note:All 220 volt 50Hz pump must be wired to the main power supply
trough an approved and correctly rated contractor.
3) Allow for gate valve in suction piping.
4) Pump suction and discharge connections have moulded in thread stops,do not try to screw pipe in
beyond these stops.
* FILTER TANK and MULTIPORT VALVE
1) Loading the sand media.Filter sand media is loaded through the top opening of the filter.
a) Loosen the plastic clamps from tank neck.
b) Cap internal pipe with plastic cap to prevent sand from entering it.
c) We recommend filling 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.
2) Assemble filter control valve to 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 neck and tighten just enough so that the
valve mayBe 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 with hose.After connections are made,
tighten clamps with screwdrive,tapping around clamp with screwdrive handle to help seat valve
flange clamp.
3) Make return to pool pipe connection to control valve opening marked RETURN and complete other
necessary plumbing connections,suction lines to pump,waste,etc.
4) To prevent water leakage,be 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.
