Water connection
Water inlet connection
This appliance may be fed with either hot
(maximum 60 °C) or cold water.
Nevertheless we advise you use a cold
water supply. A hot water supply is not
always efficient with heavily soiled crockery
as it shortens the washing programmes a lot.
For making the connection itself, the
coupling nut fitted to the appliance inlet hose
is designed to screw onto a 3/4" gas thread
spout or to a purpose made quick-coupling
tap such as the Press-block.
The water pressure must be within the limits
given in the ‘Technical data’. Your local
Water Authority will advise you on the
average mains pressure in your area.
The water inlet hose must not be kinked,
crushed, or entangled when it is being
connected.
The appliance features inlet and drain hoses
which can be turned either to the left or the
right to suit the installation by means of the
locknut. The locknut must be correctly fitted
to avoid water leaks.
If the appliance is connected to new pipes or
pipes which have not been used for a long
time, you should run the water for a few
minutes before connecting the inlet hose.
This appliance has been fitted with safety
features which will prevent the water used in
the appliance from returning back into the
drinking water system. This appliance
complies with the applicable plumbing
regulations.
Caution! Do not use inlet and drain
hoses which have previously been
used on another appliance.
Water drain connection
The end of the drain hose can be connected
in the following ways:
• To the sink outlet spigot, securing it to the
underside of the work surface. This will
prevent waste water from the sink
running into the appliance.
• To a stand pipe provided with venthole,
minimum internal diameter 4 cm.
max 85 cm
min 40 cm
max 400 cm
The drain hose can face either to the right
or left of the appliance.
Ensure the drain hose is not bent or
squashed as this could prevent or slow
down the discharge of water.
The sink plug must not be in place when the
appliance is draining as this could cause the
water to syphon back into the appliance.
If you use a drain hose extension, the
internal diameter must be no smaller than
the diameter of the hose provided.
Likewise the internal diameter of the
couplings used for connections to the waste
outlet must be no smaller than the diameter
of the hose provided.
