procedure there must be no smoking,
open ame or any other electrical
appliance operating nearby. If hydrogen
is discharged through the tap it will
probably make an unusual sound as
with air escaping.
Water Quality
Your Dux water heater has been
manufactured to suit water conditions of
most Australian metropolitan supplies.
Please note that harsh water supplies
can have a detrimental effect on the
water heater and its life expectancy. If
you are unsure about your water quality
you can obtain information from your
local water supply authority.
The water heater is designed for use in
areas where the Total Dissolved Solids
(TDS) content of the water supply is less
than 2500 mg/L. In areas where the
TDS exceeds 600mg/L the magnesium
alloy anode (supplied in the heater) may
become over reactive. To alleviate this,
the anode should be replaced with an
aluminium alloy anode, available from
your local Dux supplier.
Water can also be very corrosive,
measured by the saturation index. If the
water saturation index is greater than
0.40 an expansion control valve should
be tted and where the index is greater
than 0.80 the water heater installed
should be a Hard Water Model. Please
consult our Service Department for
advice if required.
How Long Will The Heater Run
Each Day?
The length of time that the heater will run
each day will vary dependent upon the
amount of hot water being used by the
household.
Caution: All water heaters have
the ability to produce hot water in a
surprisingly short time. To reduce the
risk of scald injury, it is mandatory
under the requirements of Australian
Standards AS3500 that an Australian
Standards approved temperature
control valve be tted to the hot water
supply pipe work. This valve should be
checked at regular intervals to ensure its
operation and settings remain correct.
