INSTALLATION
1 Position the filter on a flat surface close to a drain or any other properly
trapped outlet, and in a position where the filter can service all the water
lines which require the filtered water. The filter should be placed far
enough away from a water heater to avoid any hot water backup into the
filter. The EAF model filters require a standard or weatherproof 3 pin 10
amp power point, depending on the location of filter installation. Note that
valve operation is at 12 Volt and the Logix 742 is the controller fitted as
standard.
2 Refer to: Operation Manual, 742/762 Control, 255 and Performa series
valves, pgs 15 -18.
3 Remove filter valve by unscrewing, anticlockwise. Pull the distributor
assembly out of the valve and place in tank (the distributor assembly is
the piece of tube with the strainer on the end inserted in the valve base).
Plug or cover the top end of distributor tube making sure no media can
enter the tube.
4 Fill tank to about 1/3 full with water, make sure the distributor is sitting
on the bottom of the tank, then place the media in the tank as follows,
leveling media between each layer. DO NOT shake filter to level the
media.
5 Remove plug or cover from the distributor tube making sure you do not
lift the distributor. Top up filter tank with water. Smear o-ring lubricant on
valve o-ring and replace valve onto tank (hand tight is usually sufficient),
making sure the distributor tube is properly inserted into the valve base.
6 Allow the media to soak for a minimum of two (2) hours before proceeding
place into service, preferably overnight, with the control valve in the
“Backwash” position. Carbon filters should soak for at least 24 hours,
preferably 48 hours.
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. For top up hints see next
section.
7 Run a hose (not supplied) from the drain outlet on the valve to the drain.
The hose should not be longer than 7 metres, be reduced or restricted,
not have any rises and should have an air gap of at least 40mm at the
drain entrance.
