3. In a clockwise motion screw the center pipe (7) onto the filter grid (8) securely by hand (see
drawing 11.2).
4. Vertically insert the filter grid and center pipe assembly into the tank. Ensure filter grid
assembly is securely fitted to the bottom of the tank, and the center pipe is vertically
centered inside the tank (see drawing 11.3).
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 sand filter grid and center pipe
assembly is securely in place on the tank bottom, and the center pipe (7) is vertically
centered inside the tank.
1. To prevent sand from falling into the center pipe top opening when pouring the sand, cover
the center pipe top opening with a cup or similar object (see drawing 12).
2. With one person holding the center pipe to keep it centered, pour the sand into the tank at a
slow rate manually to prevent the filter grid assembly from shifting (see drawing 13).

3. Fill the tank approximately half way first to 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 filter grid (8) from excessive shock (see drawing 14).
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 14 & 15).
5. Remove the protective cup from the center pipe top opening.
6. Wash away all sand around the top edge of the tank.
IMPORTANT: Ensure the center pipe (7) remains centered after sand loading is completed
before proceeding to the next step.
