This Dux water heater is designed such
that there is little to do regarding system
maintenance other than that detailed in
this
Owner’s Manual .
Personally inspecting or servicing any
part of the system is not recommended.
Anodes
The recommended time after installation
when the anode should be inspected by
an authorised person is 5 years.
After each 5 years of operation you
should contact the local service agent
to replace all safety valves and anodes
to ensure continued system life and
operational safety. In locations where
the water has a TDS greater than 600
ppm, this service is recommended each
3 years.
Six Monthly Service – By Owner
Operate the Pressure & Temperature
Relief Valve for approximately 10 seconds
by operating the easing lever on the
valve to ensure water is relieved to waste
through the relief drain pipe. Check to
ensure the valve closes correctly.
Five Year Service – By Authorised
Personnel Only

out by a licensed tradesperson. It is
recommended that this service be
carried out by your local Dux agent.
