INSTALLATION
Only simple tools 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 in the right position so that the piping
connections, multiport valve are convenient and accessible for operation and
service. Position the tank with MPV in place to determine final position for piping.
2. Filter media is loaded through the top opening of the filter.
a. (For 500/650) Loosen the flange clamp and remove filter multiport valve (if
previously installed).
a. (For 700/800) Loosen the flange Nuts and remove filter multiport valve (if
previously installed).
b. Cap internal pipe with plastic cap to prevent filter media from entering it.
c. We recommend filling the tank approximately 1/2 way with water to provide a
cushion effect when the filter media is poured in. This helps protect the under-drain
laterals from excessive shock.
d. Carefully pour in correct amount and grade of filter media. (Be sure centre pipe
remains centred in opening.) Media surface should be levelled and should come to
about the middle of the filter tank. Remove plastic cap from internal pipe.
3. Assemble filter multiport valve onto the filter tank.
a. Insert multiport valve (with O’ring or casket in place) onto the tank neck, taking
care that the centre pipe slips into the hole in the bottom of the valve.
b. (For 500/650) Place clamp around valve flange and tank flange and tighten just
enough so that the valve may be rotated on tank for final positioning.
b. (For 700/800) Place nuts on all studs around valve flange and tighten just enough
so that the valve casket seals (Do not over tighten).
c. Carefully screw pressure gauge (with tread tape) into tapped hole in valve body.
Do not over-tighten.
d. Connect pump to multiport valve opening marked PUMP. After connections are
made, recheck to ensure nuts or clamp band on multiport valve flange are tight.
4. Make the return to pool pipe connection to multiport 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.
