Sand loading:
IMPORTANT: Use only No. 20 silica 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 filled between the “MAX” and “MIN” marked gauge on the center
pipe. Evenly spread and level out the sand by hand (see drawings 17 & 18).
5. Remove the sand shield (6).
6. Wash away all sand around the top edge of the tank.
