Installation Requirements
Water Heater Support:
The water heater must be installed on a
flat, solid, non-combustible supporting
surface. The weight of the water heater
should not cause deformation to any
part of the building structure.
It is recommended that a plinth is
installed under the water heater.
The water heater must be installed
plumb and level.
The water heater must also be secured
to a durable structure using the wall
brackets supplied loose with the water
heater. Note that the gas or water
pipework must not be used to support
the water heater.
The wall brackets are designed to be
installed on each side of the water
heater with the long leg against the side
of the water heater and the short leg
against the wall. The brackets should be
located near the top of the water heater,
approximately in line with the Outlet
and Relief Valve sockets. Note that
once installed, the brackets should not
obscure any labels on the water heater.
The brackets should be fixed to the wall
with suitable fasteners and fixed to the
water heater with the self drilling screws
provided.
Water Supply:
This water heater has been
manufactured to suit the water
conditions of most Australian
metropolitan supplies.
Please note that certain water supplies
can have a detrimental effect on the
water heater and its life expectancy. If
you are unsure about the water supply
you can obtain information from the
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. The Tank Failure
Warranty does not apply in areas where
the TDS exceeds 2500 mg/L.
In areas where the TDS exceeds
600mg/L it is possible that the
magnesium alloy anode (supplied in
standard water heaters) may become
overreactive. To alleviate this, the
magnesium anode should be replaced
with an aluminium alloy anode.
Aluminium alloy anodes are 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. Please consult Dux
After Sales and Service for advice if
required.
