Deciding the wiring route
• You have a choice of whether to feed
the electric cable through the side or
through the back of the unit,
• If it is gong to be through the side of the
unit, cut out the plastic lug to expose the
rubber sleeve (diagram 2.)
• If it is going through the back of the unit, cut
through the grommet on the backplate with a
sharp knife. Make sure that you do not remove
the grommet from the backplate (diagram 3.)
Feed the cable through the grommet before
you mount the unit to the wall. If you are
using an approved cable fitting, remove the
grommet.
Mounting on the wall
• Undo the retaining screws on the cover
and take the cover of the unit. Hold the
backdate in position against the wall while
you mark the four mounting holes.
• Drill the holes and secure the unit to the
wall using the four no. 8 wood screws
supplied
WARNING - IMPORTANT
Do not install a non-return check valve
within 6 feet of the inlet.
Plumbing in the unit
Fitting the pipes
• The unit should be connected directly to
the main cold water supply and not to pre-
heated water. The unit should be installed
with service valves on both the inlet and
outlet.
• We recommend that you use ½"
copper or high pressure flex
connections.
• Use Teflon tape for sealing pipe threads.
Do NOT use pipe dope.
• Remember to keep the hot water pipe
runs as short as possible. In some cases
it may be worth fitting a second unit to
serve an additional fixture.
• If the unit is to supply more than one
sink, a similarly flow restricted
aerator should be used at each tap.
If not, the highest flowing outlet will
take all the water under dual usage.
• After the unit has been plumbed in, and
before you wire it, flush it with water to
remove any debris or loose particles.
Failure to do so may make the unit
inoperable.
Connecting the unit to the pipes
• The inlet and outlet are clearly marked
on the unit. They each have a ½" NPT
connector.
• Install a ball valve in the cold water line.
This valve can be used to turn off the
water supply to the unit if it needs
servicing, or to reduce the water flow if it
is too high.
• If the unit is to supply a sink, we
recommend that you use aerators, which
you can get from your local
distributor/dealer.
• As a condition of installing this product in
the Commonwealth of Massachusetts a
pressure relief valve must be installed on the
cold water side by a licensed plumber. MGL 42
