4. The filter is ready to be moved into its final position. The system
must be placed on level solid earth. When the filter is filled with
sand and water it can weigh several hundred pounds.
5. Be certain to install the precise amount of filter sand listed on
your filter name plate. You must use only No. 20 standard silica
sand having a uniformity coefficient of 1.75 or less. No. 20 silica
sand has a particle size of .018-.022 inches (.45 to .55 mm).
Before pouring the sand into the filter, look inside and check the
lower under drain for broken or loose laterals (or fingers), which
may have been accidentally damaged by rough handling during
shipment. Replace any broken parts if necessary.
6. Install the sand guide in the top of the filter and fill the tank about
half full of water. Pour the sand into the top of the filter at a slow
rate so that the weight of the sand does not damage the laterals.
After the required amount of sand has been installed, remove and
discard the sand guide. Wash away all sand around the opening at
the top of the tank.
7. Be sure top of filter is free of any sand or debris and valve o-ring
is in place on valve body. Install valve so that the port locations
are in the desired final position. Valve ports are labeled with the
location of where they should be connected i.e. pump port must
go to pump discharge, waste port must go to the waste line and
return port must go to
the pool return.
8. Insure that the valve is
firmly pushed into the
top of the tank and that
the flange of the tank
and the flange of the
valve are contacting
each other. See
Figure 1.
9. The plastic clamp can now be installed.
Place the clamp half over the valve
flange and the tank flange as shown
in Figure 1. Insert the clamp screws
and nuts into the clamp making sure
that the nuts are located in the special
hexagonal retainer slots on the clamps.
