If only a cold water supply is available,
connect the two hoses to a cold water
outlet by means of a «Y» connection
piece.
Installation should comply with local
water authority and building regulations'
requirements.
The appliance must be given a separate
cold water supply and not be connected
to a mixer tap, a single outlet water
heater or a booster pump. A minimum
water pressure of 7 psi is required for the
safe operation of the appliance.
If you cannot make the cold water
connection direct from the rising mains,
you may be able to operate the appliance
from your cold water storage system.
There should be a minimum distance of
5.02 m (16.5 ft) between the appliance's
inlet and the bottom of the tank.
There will be sufficient pressure for the
hot water supply from the hot water
cylinder if the height between the
appliance's inlet and the bottom of the
cold water storage cistern (not between
the appliance and hot water cylinder) is
at least 2.74 m (9 ft).
If you are operating the appliance on the
minimum pressure of 7 psi, it may fill
slowly. This flow can be increased by
removing the small restrictor contained
within the inlet valve. In order to remove
the restrictor, first turn the water off and
unplug the appliance. Disconnect the
water supply hose from the inlet valve,
pull out the mesh filter inside the valve.
Remove the restrictor (which is a small
round washer) with the aid of thin-nosed
pliers.
Replace mesh filter and re-fit hose.
If the water supply in your area is hard it
is possible that the filters situated in the
fill valves can become blocked with sand
or limestone deposits and in extreme
cases this can cause a breakdown of the
fill valves ie: no water fill or continuous
filling.
We would suggest that you install
supplementary strainers which should be
fitted on the fill hoses of your machine.
For information about the availability of
these supplementary strainers you should
contact your local plumber.
If you intend the drain hose from the
machine to empty into a sink, make sure
the sink is empty and that the plug hole
is not blocked.
Where the machine is permanently
plumbed in, hook the end of the hose into
a standpipe installed for the purpose.
It should have an internal diameter of at
least 38 mm (1 V2in) thus leaving an air
gap between hose and pipe, and should be
designed in such a way that the water
level within it never covers the end of the
hose.
