Owner's Manual – Proflo Electric Storage Water Heaters
Operating Instructions
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 where
H0421
0421
Rev. K
the TDS exceeds 600mg/L it is possible
that the magnesium alloy anode
(supplied in the heater) may become
over-reactive. To alleviate this,a hard-
water model is recommended or the
magnesium anode should be replaced
with an aluminium alloy anode.
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 electrical heating element
in the water heater should be replaced
with a low power density Incoloy heating
element. 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 accu-
mulate in the top of the water cylinder.
To dissipate this gas safely it is recom-
mended 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 operat-
ing 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.
