14.
Finally fit the Aqua2use GWDD tank cover
Q
to the tank and lock it using the two
Stainless steel clips provided.
15.
The Aqua2use GWDD unit can be buried and backfilled with clean loose sand up
to the outside lip on the main container. Maximum burying depth is 400mm (15.7”). Make
sure the lid is still accessible and that dirt or other material will not enter the unit or
interfere with the bypass valve.
Your Matala Aqua2use GWDD unit is now ready for operation.
GRAVITY OPERATION OF MATALA AQUA2USE GWDD UNIT
1.
The assembly of the Gravity operated unit is exactly the same as the Pump operated unit.
The difference is that the discharge point is now the same as the drain point in the pump
system. It is not recommended to bury a gravity system.
2.
Because you are not using a pump to produce the head pressure to move the water out of
the Aqua2use GWDD, it is critical that the location of the Gravity unit is of sufficient height
to operate the drip system.
Generally 1 metre (40 inch) is the absolute minimum head required.
Please refer to manufactures recommendations as this will differ between products.
3.
Connect a length of 25mm (1”) lilac pipe from the point
M
to your dripper system. Using a
larger pipe will mean less friction loss. This is critical for the efficient operation of a gravity
system.
4.
Fit a bypass tee and two inline vales to this pipe before it connects to the drip system.
Both valves are located on the downstream sides of the tee.
By opening one valve and closing the other this will allow you to flush out any left over
sludge after you clean the filters. The drain flush line can be plumbed back to your sewerage
system.
TROUBLE SHOOTING
Water does not flow into
Check the diverting valve, reset to correct position.
