SETUP INSTRUCTIONS (continued)
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 3)
.
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 4)
.
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 from excessive shock
(see drawing 5)
.
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 5 & 6)
.
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.
