Safety

This appliance is not intended for use

by persons (including children) with

reduced physical, sensory or mental

capabilities, or lack of experience and

knowledge, unless they have been given

supervision or instruction concerning

use of the appliance by a person

responsible for their safety.

Children and animals should be

supervised to ensure that they do not

interfere with the appliance.

Filling The Water Heater

Open all hot water taps. Open isolating

valve at the cold water inlet slowly 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.

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

Owner's Manual – Proflo Electric Storage Water Heaters

Operating Instructions

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.

Water can also be very corrosive, the

measure of this is the saturation index.

If the water saturation index is greater

than 0.40, an expansion control valve

should be fitted. If 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.

Caution

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.
