•
Consider constructing a concrete or wooden platform.
•
Avoid placing on elevated surfaces to prevent tipping and to
make filling easy.
2. Level the filter with a contractor’s level. Check both front to back
and side to side.
3. Where possible, position standpipe assembly facing a wall with
the flexible Outlet Tube turned in a convenient direction.
Filter Installation
Note:
You must ALWAYS add Gravel or Sand into standing water.
If necessary, replace the Diffuser Plate and add additional water to
the filter so that you are always pouring Gravel or Sand into standing
water.
1. Fill with about 4 gallons of water. Confirm there are no leaks.
2. Add Underdrain Gravel to a depth of about
7 cm (3125 ml or about 9.6 lbs). This is the
bag with a green label if purchased through
Triple Quest. Make sure this layer is level.
3. Add 5.7 cm of the smaller Filtration Gravel
(3350 ml or 9.9 to 10.6 lbs). This is the bag
with a yellow label if purchased through Triple
Quest. Make sure this layer is level. Both layers of gravel should
add up to a depth of about 12.7 cm together.
4. Rapidly in a sweeping motion, fill the Filter Body with 34 liters (49.9
kilos or 110 lbs) of Sand (sand from Triple
Quest is marked with a red label). Make sure
the sand comes all the way up to the raised
textured line that is on the inside of the filter
body. It is important to do this as fast as pos-
sible to prevent sand stratification and the filter
plugging. It is helpful if two people are avail-
able to pour the sand simultaneously. Make sure this layer is level.
Save any extra sand for maintenance later.
5. Place the Diffuser Plate and the Filter Lid
on the Filter Body. Identify the filter with
location, date, serial number, and name of
installer on an Installation Survey form.
