built-under dishwasher – DX303
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.
– Water pressures between 50kPa and 800kPa are
acceptable.
– A pressure-reducing valve must be fitted if the cold
water supply can exceed 800kPa. (Refer also to the
remarks in the section below concerning water hammer.)
•
Hot water connection
Hot water connection is an option, providing the supply
conforms to the following conditions:
– The maximum permissible temperature for the hot
o
supply is 60
C. Any higher temperature may cause
damage to water carrying components and dishware life
may be reduced.
– If 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°C, a
water temperature tempering valve should be installed
in the water service.
– Water pressures between 50kPa and 350kPa are
acceptable. A pressure-reducing valve must be fitted
if the hot water supply can exceed 350kPa.
•
Water hammer
Quick 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.
To prevent water hammer, we recommend the fitment
of a Noise Reduction Valve in the water suppy line. These
valves also act as a pressure reducing valve with the added
benefits of:
– reducing the chance of a burst hose; and
– reducing the water noise whilst the dishwasher is filling
with water.
Pressure 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.
IMPORTANT
• Ensure that hoses are not crushed or kinked under or
behind the dishwasher.
• After connecting hose to the tap, turn the tap on and
check to ensure that there are no leaks.
