STARTING THE INSTALLATION – ALL MODELS
Before commencing the installation, ascertain that the water pressure is not too low or high. Optimum operating pressure is 1.75
to 4 Bar (25 to 60 p.s.i.). If daytime pressure exceeds 4 Bar (60 p.s.i.), then a pressure limiting valve should be installed. These are
available from your supplier and should be located as shown in Fig. 1. Pressure can be determined by applying a gauge to an
outside tap or single pillar tap or by contacting your local Water Board. If water splashes out over the sink when the cold tap
is turned fully on, it is a good indication of high pressure.
DRAIN THE RISING MAIN
Turn off the existing cold mains supply stopcock and drain down any water in the pipe via the “drain off cock” or kitchen cold
tap. To allow air to enter the main via the ballvalve in the loft tank, run a small amount of water from the cold tap in the
bathroom. If all your cold supply connections are off the rising main, open a tap at the highest point.
INSTALLING THE BY-PASS SET
Cut the rising main and install the inlet, outlet and by-pass valves as shown in Fig.1. Install the non return check valve and
connect hard water supply to kitchen drinking tap and/or outside garden supply (if required). Fit the pressure limiting valve
(if applicable) prior to the hard water inlet to the water softener.
Turn the inlet and outlet valves to closed (handle pointing across water flow). Turn the by-pass valve to open (handle pointing
with the water flow).
Ensure the “drain off cock” is closed and turn back on the existing stopcock. This will allow hard water to again enter the system.

sealer such as PTFE tape.
All MODELS
From the inlet valve connect a hose to the inlet port marked “
” on the
water softener control valve (Fig. 1). Check that the rubber washers (Fig. 2)
are in place and hand tighten nut plus half turn with a spanner. Connect
outlet hose from outlet valve to water softener in the same manner.

Your water softener comes complete with a basic 10mm flexible trade installation kit (see detail sheet with kit). Alternatively you
can disregard the hoses and “hard plumb” the connections in 15mm or 22mm copper tube.
Unvented/direct mains fed plumbing and hot water systems: For maximum flow rates disregard the inlet and outlet hoses, valves
and non-return check valve. “Hard plumb” using 22mm copper tube and fittings. A 22mm non-return check valve will also be
required. It must be UK Water Fittings Byelaw Scheme (W.F.B.S.) listed.
The following are available from Culligan or your retailer:
22mm non-return valve.
Pressure limiting valve 3.5 Bar (50 p.s.i.) for high pressure areas.
Hardness measuring kit: For accurate testing.
Drinking water tap: For hard water drinking point.
Drinking water filter kits.
12.5mm inlet/outlet hoses.
LOW-HEIGHT – RESTRICTIONS (under low sinks etc)
If you are in a situation where height is a problem, it is possible to mark out the shape of the water softener cabinet and cut out
the wooden plinth. Allow the “Cut-Out” to fall through the hole to act as a smooth base for the water softener to sit on. The
gap between the water softener and the cut out can be filled with a plastic edging strip.
