Fixing to the wall
● Undo the retaining nuts and take the
front cover off the unit. Hold the
backplate in position against the wall
while you mark the four fixing holes.
● Drill the holes and fix the unit to the wall
using the four No 8 x 38mm wood
screws supplied.
Plumbing the unit
Warning
- Do not use a non-return valve in
the inlet feed to the unit.
- Do not fit the unit within 2 metres
of a stop valve.
Fitting the pipes
● The unit should be connected directly to
the main cold water supply.
In some cases it may be worth fitting a
second unit.
● If the unit is to supply more than one
basin outlet, the head should be the
same at each outlet if they are to be
used at the same time. If not, one
outlet will take all the water.
● When the pipework has been plumbed
on, flush it through with water before you
connect the unit, to remove any swarf
or loose particles.
Connecting the unit to the pipes
● The inlet and outlet are clearly marked
on the unit. They each have a
3
/
8
" NPT
connector.
● Two
3
/
8
" NPT x 15mm adapters are
included with the unit to attach it to the
inlet and outlet pipes.
(Model 45-793270: See addendum
sheet for local installation requirements).
● We recommend that you use 15mm
copper or stainless steel pipe for the
inlet and outlet connections.
(See addendum sheet for local
installation requirements).
● Use PTFE tape for making screw joints.
Do NOT use a jointing compound.
● Remember to keep the hot water
pipe runs as short as possible.
● The unit comes with a service valve
(diagram 6) which should be fitted on
the inlet of the unit. You can do this
using the inlet adaptor provided. The
valve can be used to turn off the water
supply to the unit if it needs servicing,
or to reduce the main supply pressure if
it is too high.
