connecTion To waTer supply
The inlet hose should be inspected every 12 months for
deterioration and replaced if necessary.
• Cold water connection
– We recommend connection to a cold water supply.
– W ater pressures between 50kPa and 800kPa are
acceptable.
– A pressure-reducing valve must be fitted if the cold water
supply exceeds 800kPa. (Refer also to the remarks in the
section below concerning water hammer.)
• Hot water connection
H ot water connection is an option, providing the supply
conforms to the following conditions:
– T he maximum permissible temperature for the hot supply
is 60
o
C. Any higher temperature may cause damage
to water carrying components and crockery life may
be reduced.
– I f your dishwasher is likely to be connected to a solar
hot water system, drip heater, (or similar system),
the temperature must not exceed 60°C. Where it is
anticipated that the temperature will exceed 60
a water temperature tempering valve should be installed
in the water service.
– W ater pressures between 50kPa and 350kPa are
acceptable. A pressure-reducing valve must be fitted
if the hot water supply exceeds 350kPa.
• Water hammer
Q uick action household taps and fast acting water valves
on appliances can cause water hammer. This can result in
very high water pressures. High pressure can cause failure
of the pressure reducing valve (where fitted), or the water
valve in your dishwasher.
T o prevent water hammer, we recommend the fitment
of a Noise Reduction Valve in the water supply line.
These valves also act as a pressure reducing valve with
the added benefits of:
– Reducing the chance of a burst hose
– R educing the water noise whilst the dishwasher is filling
with water
P ressure reducing valves, water temperature tempering
valves and noise reduction valves are available from major
plumbing suppliers. DO NOT connect your dishwasher to
the outlet of an unpressurised displacement instantaneous
water heater, (for example a push through type sink heater)
as damage to the heater may result.
• Water inlet hose with safety valve
S ome models are supplied with an inlet hose that has
a double-walled water hose and a safety valve on the
threaded hose fitting next to the tap. Therefore the water
inlet hose is only under pressure while the dishwasher
is filling. If the water inlet hose starts to leak during this
operation, the safety valve, controlled by the dishwasher,
cuts off the water supply to prevent flooding.

CAUTION
Please take care when installing the safety inlet hose:
• T he distance between the bottom edge of the safety valve
and the floor on which the dishwasher is standing must be
at least 300mm.
• T he electrical cable for the safety valve is in the double-
walled water inlet hose. Do not immerse the water inlet
hose or the safety valve in water.
• Do not attempt to shorten the inlet hose.
• I f the water inlet hose or the safety valve is damaged,
immediately turn off the power and remove the mains plug.
• A water inlet hose fitted with a safety valve must only be
replaced by a qualified Service Engineer.
• I f your dishwasher is fitted with a "safety hose" you will
need an opening of at least 45mm x 90mm in your
cupboards in order to feed the hose through it.

IMPORTANT
• E nsure that hoses are not crushed or kinked under or
behind the dishwasher.
• A fter connecting hose to the tap, turn the tap on and
check to ensure that there are no leaks.
