Open all hot water taps. Open isolating valve at the cold water inlet and allow water
heater to fill until water flows through the system. Close each hot water tap after the air is
expelled from its line. As noted previously power is not to be turned on until the water
heater is filled with water.
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 it is possible that the magnesium alloy anode (supplied in the heater) may
become over reactive. To alleviate this, the magnesium alloy anode should be replaced
with an aluminium alloy anode, available from your local Dux supplier.
• Hard Water Models : Water heaters with an "H" in their model designation (eg.
250H136) are factory fitted with an aluminium anode and a special hard water
element.
Water can also be very corrosive, the measure of this is the saturation index, if the water
saturation index is greater than 0.40 a expansion control valve should be fitted 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 advise if required.
If the water heater is left in an operating condition and unused for two weeks or more, a
quantity of hydrogen (which is highly flammable) may accumulate in the top of the water
cylinder. To dissipate this gas safely it is recommended that a hot tap be turned on for
several minutes at a sink, basin or bath, but not a dishwasher, clothes washer or other
appliance. During this procedure there must be no smoking, open flame 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.
Where the Water Heater is not installed in accordance with the listed advice the
water heater will not be covered by the Terms of Warranty.
