Notice to Victorian Customers from the Victorian Plumbing
Industry Commission
This water heater must be installed by a licensed person as
required by the Victorian Building Act 1993. Only a licensed
professional will give you a Compliance Certificate, showing
that the work complies with all the relevant standards. Only a
licensed person will have insurance protecting their
workmanship.
Make sure you use a licensed person to install this water heater
and ask for your Compliance Certificate
Water temperature warnings
▶ Tomeetregulatoryrequirements the temperatureof stored
water heater must not be less than 60°C.
▶ The thermostat on your water heater is factory pre-set to
65°C which is suitable for the vast majority of domestic
applications.
▶ The thermostat setting can be adjusted between 50°C and
70°C. Adjustment must be made by an electrician or other
suitably qualified trades person.
Hydrogen warnings
General safety warnings
This water heater is fitted with a combination pressure and
temperature PTR relief valve (approved to AS1357), a
thermostat, and a resettable over-temperature cut-out.
▶ It is imperative that all safety devices are not tampered with
as this will void warranty.
WARNING:
Hot water can cause scalds. Children,
disabled and the elderly are at greatest risk.
Scalds from hot water can result in severe
injuries to young children. Feel water
temperature before bathing or showering.
Scalds can occur when children are exposed
directly to hot water when they are placed
into a bath that is too hot.
WARNING:
Additional temperature control or limiting
devices such as tempering valves may be
required to be fitted to this water heater to
meet regulatory requirements.
WARNING:
If the hot water heater is not used for two
weeks or more, a quantity of hydrogen gas,
which is highly flammable, may accumulate
in the water heater. To dissipate this safely,
it is recommended that a non-electrically
operated hot tap be turned on for several
minutes at a sink, or bath, but not at a
dishwasher or other appliance.
During this procedure there must be no
smoking, open flame, or any electrical
appliance operating nearby. If hydrogen gas
is discharged through the tap, it will
probably make a sound like air escaping.
WARNING:
Do not operate this water heater unless all
safety devices are fitted and functioning
normally.
CAUTION:
Failure to operate the relief valve easing gear
at least once every six months may result in
product fault.
It is important that the easing gear on the
valve be raised and lowered very gently.
Failure to do so may result in the water
heater cylinder failing, or faulting under
certain circumstances.
WARNING:
Relief valves should be checked to be in
sound working order at regular intervals not
exceeding 5 years, and more frequently in
areas subject to poor water quality.Checking
should include operation of the relief valveto
remove any lime deposits.

WARNING:
It is normal that small quantities of water (up
to 15 litres of water in a 24 hour period) are
released by the valve during the heating
cycle.Continuous leakage of water from the
valve may indicate a problem with the water
heater.
If the valve does not discharge water when
the easing gear is operated , or does not seal
again, a service call should be made without
delay.
The PTR valve is not serviceable.
CAUTION:
The activation of the thermal cut-out
indicates a possibly dangerous situation.
▶ Do not reset the thermal cut-out until the
water heater has been serviced by a
qualified person.

3.1 Overview
Fig. 2 Appliance overview
3.2 Features and general information
Your storage electric water heater consists of a vitreous enamel
lined steel cylinder, an internally adjustable thermostat,
a pre-painted zinc-coated steel shell or exterior, an immersion
type element, a sacrificial anode, and a PTR safety valve.
Water is stored within the steel inner tank and is heated to the
thermostat set temperature by the element. The PTR valve
ensures water pressure and temperature does not exceed safe
limits during the heating cycle. As the water is drawn off in
normal every-day use, the thermostat will monitor the tank
temperature and activate the element to ensure hot water is
available.
The tank is a mains pressure tank. It is designed to supply water
at mains pressure (above 350kPa).
If the maximum cold water pressure exceeds 680kPa, a
pressure limiting valve must be fitted.
The sacrificial anode in your water heater (located at the top of
the water heater) will slowly erode to protect the cylinder.
Water heater life expectancy is dependent on a number of
factors including water heater usage patterns, water quality
and water pressure.
Water Quality
This water heater has been designed and constructed to be
suitable for connection to most water supplies in Australia and
The thermostat is factory set at 65°C and is
adjustable from 50°C to 70°C by an
authorised person.
Bosch recommends that the anode be
inspected and replaced every five years or
more frequently in poor water quality areas.
NOTICE: Please refer to the Water Quality
Statement on Page 19, and the Warranty
Details on page 20.

New Zealand. However, in areas where Total Dissolved Solids
(TDS) exceeds 2500mg/L, detrimental effects on water heater
performance and longevity will result.
Anode
Should your water supply have a TDS of greater than 600mg/L,
the installed anode must be aluminium (blue) or hydrogen gas
can accumulate at the top of the water heaterin long periods of
no use. When this is likely to occur, the installer should instruct
the householder on how to dissipate the gas safely. This
process is explained under “Hydrogen warning” on page 4. Any
change of anode must be carried out by an authorised service
person.
Corrosive Water
Water deemed to be corrosive can attack copper parts causing
them to fail. When the water supply Saturation Index (check
with your local water supplier for additional information) is less
than -1.0, water is deemed corrosive and a corrosion resistant
heating element should be used. When the Saturation Index is
greater than +0.40, an expansion control valve must be fitted
on the cold water line after the non-return valve. Should the
Saturation Index exceed +0.80, a low-watts density heating
element should be fitted by an authorised person.
When an ECV is required to be fitted, a small amount of water
may be discharged during the heating cycle rather than the PTR
valve.
IMPORTANT: Where fitted, gently operate the easing lever on
the ECV every six months and replace at intervals not
exceeding 5 years, or more frequently in areas with poor
quality water.
Please refer to the Water Quality Statement on Page 19, and
the Warranty Details on page 20.
Switching off the appliance
If you intend to not use the water heater for only a few days, we
suggest you leave it switched on. If the water heater is to be
switched off, the switch is generally marked and located in the
circuit board or next to the appliance. When the water heater
switch is turned back on, it may take several hours before
sufficient hot water becomes available.
Tariffs
In some regions Off-Peak Tariffs may be available for water
heaters. In these regions water heaters greater than 160L are
suitable for connection to either Continuous or Off-Peak
Tariffs. Where the household requirements for hot water
exceeds the water heater storage capacity, Continuous Tariff is
required. Where hot water demand is less than water heater
capacity, Off-Peak Tariffs may be applicable. Note that Off-
Peak tariff vary from region to region, however are generally
less expensive than Continuous Tariff rates (subject to local
regulations).
