INSTALLATION AND OPERATION INSTRUCTIONS
Before you proceed
Packaging. Remove the softener and salt tank
carefully from the packaging, lift off the cover
from the top of the softener and remove the
packaging from the inside the cover and
cabinet.
Water hardness. Before you proceed you
must be sure the softener is capable of
providing enough softened water for your
needs. This is done by checking the hardness
of the water in your home and following the
recommendations below.
Find a place for your softener.
Call your local water supply company and
they will advise the water hardness in your
area, look up water in your telephone book.
The softener should ideally be local to the
water supply for the whole house and a drain.
The salt tank should be sited not more than 3m
away from the softener, as governed by the
brine tube between the softener and the salt
tank. It should be next to an outside wall for
the overflow and be easily accessible for
filling with salt.
The salt tank can be positioned above the
softener but never below.
Remove the cover from the softener and note
the model (service) number on the label.
Given your model, check the hardness of the
water is less than hardness given in the chart
below.
You may need to adjust the salt setting, it has
been shipped to you set on 900. Instructions
on how to adjust the salt setting are given on
page 3.
Pipe size.
The softener is supplied with &frac34;” and 1” inlet
and outlet connections. Select and fit the size
connections appropriate to the connecting
pipework.
Install the softener as per the plumbing
section.
Note : &frac12;” hoses and bypass kit are suitable
for homes with a cold water storage tank, if
however your home has a combination or
direct hot water system we recommend you
install the softener using the high flow hoses
and bypass kit.
Also, if your water supply pipe is 22mm or
larger, install the softener using the high
flow hoses and bypass kit.
Your supplier can provide you with a suitable
bypass kit and hoses.

Water pressure. This can be tested with a
gauge. The ideal daytime water pressure is 2
to 6 bar, but it must not be below 1 bar or
above 8 bar.
If the pressure is above 6 bar we
recommend the installation of a pressure
reducing valve set at 6 bar, this valve is
available from your supplier.
Drinking water. We advise that a drinking
water tap is installed. Your supplier can
provide you with an easy to install drinking
water tap kit.
Important: Softened water should not be
used for baby food or drinks, also people on
a low sodium diet should not drink softened
water.

The inlet/outlet unions are fixed to the inlet and outlet ports with the large nut and
sealed with flat rubber seal. DO NOT OVER-TIGHTEN THE NUT.
Connect a hose between the softener inlet and the inlet valve, then, connect a hose
between the softener outlet and the outlet valve.
Turn off the inlet, outlet and bypass valves.
The drinking water tap connection and the garden tap connection should be made in the
pipe between the stopcock and the bypass valve.
Run the drain hose to the nearest waste pipe, typically a washing machine type
standpipe. Cut off the excess hose, this is used for the overflow pipe. Install an air gap to the
standpipe and connect the drain pipe to the air gap.
From the brine tank, push the overflow hose on to the overflow connection on the side
of the cabinet and run it downhill to the outside of the house, keep the hose as short as possible.
Connect the brine tube between the softener and the brine tank. Shorten the tube to
suit. Push the tube ends into the elbow connectors on the softener and salt tank.
