INSTALLATION OF YOUR WATER SOFTENER
PLANNING AND SITING THE INSTALLATION
The installation of a water softener is relatively easy, but we
recommend that this work is undertaken by an authorised agent.
Where possible the water softener should be sited close to the rising
main, allowing for any required hard water draw off points, i.e.
drinking tap and outside tap. Keep the drain run as short as possible
and allow for ease of service and salt access. If installed next to a boiler
or hot water cylinder you may have to protect against condensation.
When siting the softener please consider space for accessing the unit
for servicing etc. Sufficient space should be left behind the unit to allow
easy access for repairs and cleaning.
FLOW RATES
The water flow must be at least 1 litre per minute for the water
softener to work as originally designed.
FREEZING
The installation of all water fittings should be in accordance with
regional WRC regulations. The water softener, and all associated
pipework must be protected against freezing. Take special care where
the drain runs outside. Freezing will prevent recharge and cause
overflowing.
WARNING: FAILURE TO MEET THE FOLLOWING REQUIREMENTS
CAN CAUSE DAMAGE TO THE WATER SOFTENER, OR RESTRICT ITS
OPERATION.
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.
HARDWATER TAP
WRC regulations currently state that a hard water tap is always
recommended. However, where the water hardness is below 400ppm
calcium carbonate there is NO mandatory requirement for a separate
hard water drinking tap because softened water complies with the
drinking water regulations. Where the water hardness exceeds 400ppm
calcium carbonate, the sodium level will be above the 200ppm
maximum set by the drinking water regulations so a separate hard
water drinking tap becomes mandatory.
It is also recommended that the garden tap is left with hard water
supply. Always check current regulations and seek advice from your
authorised agent.
PRESSURE
Low or high pressure could lead to damage or non-operation of the
water softener. If the daytime pressure exceeds 4.76 BAR (70 psi) a
pressure reducing valve should be fitted. If daytime pressure is less
than 1.7 BAR (25 psi) a pressure pump is required.
Note: Night-time pressure will be much higher than daytime.
SPECIFICATION REQUIREMENTS
Maximum water temperature 49 °C (120 °F)
Maximum daytime working pressure 4.76 BAR (70 psi)
Minimum working pressure 1.7 BAR (25 psi)
Minimum system flow 0.06m3/hr
UNVENTED OR DIRECT SYSTEMS
Connection to the water softener should be made with 22mm or 28mm
copper pipe and not with flexible hoses supplied, to ensure that a
satisfactory flow rate is maintained.
You will also require a suitably sized bypass set and check valve. Full
flow valves are recommended.
DRAIN HOSE
We recommend that the maximum length of drain hose is 1 metre
before entering an air gap. The maximum drain height above the
softener should be no more than 1 metre.

PRESSURE
Low or high pressure could lead to damage or non-operation of the water
softener. If the daytime pressure exceeds 4.76 BAR (70 psi)a pressure-
reducing valve should be fitted. If daytime pressure is less than 1.7 BAR
(25 psi) a pressure pump is required. Talk to an EcoWater agent.
Note:
Night-time pressure will be much higher than daytime.
