5. Electrical connections:
For added safety, peace of mind and ease of installation, your water softener is powered by low
voltage via a plug in transformer. This transformer must be connected to a switched socket.
6. Filling the brine cabinet, salt usage and alarm:
Now place the water softener salt in the brine cabinet. Use the care cubes (tablet salt) or block salt
(UK), from your local dealer. Notes on salt usage: Your water softener will only perform effectively if
there is salt in the brine cabinet during the regeneration process.
It is therefore essential that the salt level does not fall lower than 15 cm in depth when measured from
the base of the brine cabinet.
7. Blending control:
6
All machines are factory set to produce water that is soft. Note: If you prefer water which is less soft,
turn the blending knob on the left side of the valve anti-clockwise until the water meets your require-
4
ments.
8. Testing for the water hardness in your area:
Water hardness can vary from one location to another. To determine the hardness of the water feeding
your water softener (unsoftened supply) use the hardness test kit supplied.
Fill the test bottle supplied to the fill line with water from a hard water tap.
Add the tablets to the solution one tablet at a time.
Shake the bottle in between and keep adding tablets to the water until the solution turns from wine
red to blue, record the number of tablets as you go.
Using the data table supplied with your kit, match up the number of tablets with the hardness. You
will need this figure when programming your water softener in the next section of this manual.
9. Switching on for the first time:
Check that the inlet hoses and outlet hoses or couplings are properly connected i.e. inlet-to-inlet,
outlet-to-outlet. The by-pass arrangement (see chapter 3.4 Installation Layout) should be in the open
position in example:
the inlet- and outlet valves closed (E), (C)
Check that the by-pass valve (D) open.
Check that the mains stop valve (F) open.
Check that the Brine Cabinet (G) contains salt.
Check that the water softener is connected to the drain (J) and the overflow pipe is be linked to each
other connected.
The drain and overflow must not be linked to each other.
Gently open the inlet valve (C) so that water flows into the resin vessel.
Turn ON the power, you will hear the valve move quietly into the start position. When the
positioning process has been completed (which can take up to 5 minutes) you will hear the
movement stop, the valve has now reached its start position in preparation for the programming
procedure.
Close the by-pass valve (D).
Gently open the outlet valve (E).
Check for leaks, take corrective action to stop leaks if required.
Your water softener is now on line and you may start the valve programming procedure set out in
the next section of this manual.
I CAUTION!
Do not use jointing cement on the fitting.
f
If the drain hose or connecting pipework is likely to be subject to temperatures below 0 °C it must
f
be protected to prevent freezing. Failure to observe this precaution could lead to the water softener
overflowing.
Plug the transformer into the socket with the switch in the OFF-position.
