Insert the tube with diffuser body inside the tank as above picture shows, then place the funnel on the
tank’s mouth and out the quartz sand into the tank. A 12” sand filter requires about 19kg of sand to fill the
tank, a 14” sand filler needs about 27kg of sand to fill the tank.
4.
Remove the funnel and make sure the tanl’s neck is clean. Put the O-ring on the valve and use clamp to
fix the valve with the tank. Pump port valve direction needs to face pump’s out-port.
5.
Connect the sand tank to the pump with hose and hose adapters.
INSTALLATION NOTES:
Make sure the filter has worked under work pressure and using a pressure control calve when the system
is using a booster pump.
If the pump position is higher than the water level, it requires installing an isolation valve. It can stop the
water return back when doing the general inspection.
If the pump position is higher than the water level, it requires installation of the back water control valve.
Reduce the connection adapters and hose connection, bending as little as possible. Decreasing the water
flow scrub can reach the maximum effectiveness
Ensure solvents are not excessively applied to the fitting as this can run onto the O-ring and create sealing
issues.
Do not over tighten fittings or adapters.
