Installation of your water softener
WARNING: FAILURE TO MEET THE FOLLOWING REQUIREMENTS CAN CAUSE
DAMAGE TO THE WATER SOFTENER, OR RESTRICT ITS OPERATION.
We recommend your water softener is professionally
installed. Your installation must conform to water and
electrical regulations and local plumbing codes.
SPECIFICATION
• Maximum water temperature 49°C
• Maximum daytime working pressure 5 Bar
• Minimum working pressure 1.3 Bar
• Minimum system fl ow 0.06m³/hr
• Maximum system fl ow 3.18m³/hr
PRESSURE
Night time pressure will be much higher than
day time pressure.
If day time pressure exceeds 5 bar, a pressure
reducing valve should be fi tted. The water softener
is tested to a maximum day time static pressure of
8.5 bar, therefore the pressure reducing valve can
be adjusted to a maximum of 6 bar static pressure.
GRAVITY FED PLUMBING SYSTEMS
If the water fl ow is less than 1 litre per minute,
for the water softener to operate as originally
designed we recommend a delayed action ball
valve is fi tted within your storage tank.
UNVENTED OR COMBINATION BOILERS
The water softener and 22mm installation kit is
compatible with unvented or combination systems.
ELECTRICAL REQUIREMENTS
The water softener requires a 240 volt 50 Hz
electrical supply taken off a power supply, not
a lighting circuit. Power is supplied via a 24 volt
50 Hz transformer. You must use the transformer
supplied with the softener.
HARD WATER TAP
Fitting a separate hard water drinking water tap is
currently recommended by the UK Dept of Health
and the UKWTA. Fitment of a separate hard water
drinking tap is only required in exceptionally
hard water areas (above 400 mg/l) where
sodium content of the treated water (increased
due to the softening process) exceeds the level
laid down in the Water Supply (Water Quality)
Regulations 2000. Drinking softened water is not
recommended for people on a low sodium diet or
babies on formula feed.
CENTRAL HEATING SYSTEMS
Central heating systems should always be treated
with a suitable corrosion inhibitor regardless of
being fi lled with softened or hard water.
RECOMMENDATION FOR SITING THE
WATER SOFTENER
• Install close to the rising main
• Keep drain point as short as possible
• Keep overfl ow to outside wall as short as
possible with a constant fall
• Allow for any required hard water draw off points
• Place on a sound base
• Allow space above the valve cover lid for
servicing (recommended 75mm)
• Protect the softener and all associated pipework
against freezing, as this could cause fl ooding
• Protect against condensation in enclosed areas
LEAD PIPEWORK
Where lead pipework exists downstream of the
proposed location of the water softener, we advise
you to ask the local water authority for advice on
the replacement of lead pipework. Water softeners
should not be used with lead pipework.
DRAIN HOSE
• With pressure of 3 bar, the maximum drain run is
3m with a constant fall before entering an air gap
• The maximum height above the softener should
be not more than 2m
• The drain hose must enter the regulation air gap
to prevent back fi ll
• It is not recommended to discharge the waste
into a pumped drain
OVERFLOW
The overfl ow needs to pass through an outside
wall so that it can be seen. In accommodation
without a suitable outside wall it may be
appropriate to use a suitable tundish with the
existing overfl ow provision.
INLET/OUTLET HOSES
Refer to the Water Softener Kit Installation Guide
(single sheet) included with the installation kit.
The hoses are 500mm length with 22mm push-fi t
connections.
You may need reducers or spiggot elbows to fi x
to your existing plumbing.
FITTING THE SOFTENER
The following instructions are recommendations.
You may need to adapt the order for particular
siting and plumbing systems.
