INSTALLING ISOLATING VALVE (3)
(refer to figure 1)
Locate the pipe supplying the cold water to your kitchen sink. This
should be 15mm copper, in the unlikely event this it is not contact
your dealer for advice since this valve is unsuitable for any other
type of pipe. (If you have a water softener installed you must con-
nect the isolating valve to the hard water inlet side, not the softened
side).
Turn off the cold water supply and drain the cold main. This can
be done by opening the cold tap and then running the hot tap for a
minute or so to open the ball valve in the tank. If you have a mains
fed water system such as a combi boiler or unvented system then
you will not need to do this.
Select a straight length of copper on the cold supply to the sink with
at least an 80mm clear run. Use a copper cutter to remove a section
15mm long at least 35mm from the end. Pipe must be clean and free
of paint/solder/flux etc. If you have to use a saw (not recommended)
you will have to ensure that the ends of the pipe are filed completely
free of sharp/rough ends because this will damage the sealing ’O’
rings. See figure 3 for how to connect the pushfit fittings. Ensure
valve is closed (lever at right angle as in fig 1) and turn water supply
back on. Check for leaks.
