Sand loading:
IMPORTANT: Use No. 20 silica sand or glass sand with particle size range 0.45
to
0.85 mm (0.018 to 0.033 inches) and a Uniformity Coefficient less than 1.75.
NOTE: Before loading the tank with sand, ensure the center pipe hub assembly is
securely in place
at
the bottom
of
the tank, and vertically centered inside the tank.
1. Place the sand shield (6) over the top
of
the center pipe. Pour the sand into the tank
at a slow rate
(see drawing 15).
2.
Fill the tank approximately half way, remove the sand shield (6) from the top (see
drawing 16).

3.
Evenly distribute the sand inside the tank, then fill the tank with some water to provide a
cushioning effect when the remaining sand is poured in. This prevents the center pipe
hub
(7) from excessive shock (see drawing 17). Place the sand shield (6) back and
continue
to
pour the sand into the tank.
4. Sand shall be fi
ll
ed between the "MAX" and "MIN" marked gauge on the center pipe (see
drawing 18).

5.
Remove the sand shield (6) (see drawing 16) and evenly spread and level out the sand
by hand
(see drawing 17).
6. Wash away all sand around the top edge
of
the tank.
