Owner’s Information
What Should I Do During Holidays?
The system can monitor and control
the solar collector temperature while
you are away. Whilst the system is safe
with the power turned OFF, the collector
temperatures can reach very high
temperatures, causing high stress to
their internal components.
The power supply to the solar
controller Hotlogic pump module
must be left ON.
Warning: If the hot water system is
not used, for two weeks or more, a
quantity of hydrogen gas, which is highly
ammable, may accumulate in the water
heater. 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 ame or any other electrical
appliance operating nearby. If hydrogen
is discharged through the tap, it will
probably make an unusual noise similar
to air escaping.
Note: Important there are no user
serviceable components in the
system. Only an authorised service
representative is permitted to remove
any covers or make setting adjustments.
Do not open or adjust any electrical
covers or devices yourself.
The Dux solar water heater is designed
such that there is little to do regarding
system maintenance other than that
detailed in this Owner’s Manual. The
components in the solar side of the
system do not require maintenance.
Personally inspecting or servicing any
part of the system is not recommended.
Should you decide to personally inspect
the roof mounted system components,
it is essential that you use all safety
devices required to ensure your safety.
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.
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 the
TDS exceeds 600mg/L the magnesium
