NEUTRAFIL TOP UP
Note that most media does not need replacing on a regular basis, Neutrafil is
the exception as it is sacrificial and designed to dissolve slowly neutralising
acidity. It is likely to need topping up every 2 months or so depending on
water use and chemistry.
1) Disconnect the inlet, outlet and drain.
2) Unscrew the valve from the tank and remove it. The riser pipe in the
centre of the tank may lift up with valve. Attempt to minimise this.
3) Place a cap over the riser pipe.
4) Add Neutrafil to the tank so it is approx. 2/3 full.
5) Ensure there is no media in the tank thread. Remove the cap on the riser pipe.
6a) If the riser pipe has lifted when removing the valve it must be moved
back down into the Neutrafil.
6b) Insert a garden hose down the pipe.
E.g.
6c) Turn on the water, and push / wriggle the riser pipe pack into the tank.
The Neutrafil will rise up with the flow. Do not allow it to overflow out of
the tank. Reduce the water flow to prevent.
6d) Once the riser pipe is back in position, turn off the water. Hold the riser
pipe and remove the hose.
7) Refit the valve and reconnect.
8) Do a backwash and rinse.
