2.2 Product description
2.2.2Description of Operation
The Bosch CascadeTherm Plus is a domestic hot water, stainless
steel 315L cylinder, equipped with a Bosch KM3211WHNG
water heater as the heating source. Included is a primary
heating circuit pump which is operated by an AlphastatPlus
temperature controller, with a temperature sensor located in the
sensor pocket of the tank.
The Grundfos UPS 25-80N pump is used to circulate water from
the tank through the water heater. When the Senztek thermostat
activates the pump, the movement of water through the flow
sensor of the water heater sends a signal to the electronic
control unit. This signal triggers the following actions:
The fan starts to purge exhaust gases.
The ignition sequence begins and the gas valve opens to deliver
gas to the burner.

equipment required by local codes, and no less
than a combination temperature and pressure
relief valve certified by a nationally recognised
resting laboratory that maintains periodic
inspection of production of listed equipment
or materials, as meeting the requirements of
AS/NZS 3500.4, AS/NZS 3000 and all locally
codes and regulatory authority requirements.
10 I Installation
Two temperature and pressure relief valves are supplied and
must be installed in the tank ports marked for this purpose.
No valve or accessory of any type should be installed between
the relief valve and the tank. Please observe local codes for the
correct installation of relief valves.
The pressure rating of the relief valve must
not exceed 850 kPa, the maximum working
pressure of the water heater as marked on the
rating plate.
Relief valve easing gear should be operated

operated, the valve should be checked by an
authorised agent.
The relief valve and relief drain pipe must not
be sealed or blocked. Small amounts of water
may leak from relief valve during heating cycles.
Relief valves should be checked every six
months, or replaced at intervals not exceeding
3 years or more frequently in areas where there
is a high incidence of water deposits.
The function of the temperature and pressure
relief valve installed on this water heater is
to discharge high temperature water under
certain conditions. Therefore it is strongly
recommended that the pipe work connected
to the relief valve is able to withstand water
temperatures exceeding 99oC. Failure to follow
this recommendation may result in a dangerous
The combined kW rating of the relief valves must be 92 kW to
ensure that they are always above the maximum output power
of the water heater when operating. The supplied PTR valves
comply with this.
Never block or seal the outlet of the PTR valve
or its drain for any reason. The warranty will be
void if the relief valves or other safety devices
are tampered with, or if the installation is not in
accordance with this manual.
Connect the outlet of the relief valve to a suitable open drain so
that the discharge water cannot contact any electrical parts,
persons, or animals, and to eliminate any other possible risks.
A drain line from a relief valve must comply with the
requirements of AS/NZS 3500.4.
Always use a valve of the same rated pressure and temperature
as the PTR valves supplied with the unit.

Notes I 19
Wrong Deliveries and Transit Damage
Wrong deliveries, incorrect or damaged packing and transit
damage claims are not warranty claims. Such cases should be
directed to Bosch’s Customer Service line in Australia on ph:
1300 307 037 or in New Zealand on ph: 0800 543 352.
Bosch is required to seek personal information from an end user
who seeks to make a claim under this warranty. Such personal
information may be used by Bosch and/or any authorised
service technician (who is authorised to process warranty
claims and/or carry out warranty repairs on behalf of Bosch) for
the purpose of processing such warranty claim and also for the
provision of customer support and further information about
Bosch’s products and services (Purpose).
How to Make a Warranty Claim
If a Product fails within the warranty period, the end user must
stop using the Product and make a claim as soon as possible, in
any event before the end of the Warranty Period (see Deadlines
for Submitting Warranty Claims below).
To make a warranty claim under this voluntary warranty,
call the Bosch Customer Contact Centre (in Australia on
ph: 1300 307 037 or in New Zealand on ph: 0800 543 352).
Please be ready to provide the model and serial number, date
of installation, purchase details and a full description of the
problem. Alternatively, for claims in Australia, you can post
details of your claim to Robert Bosch (Aust) Pty Ltd, Attn TT
Warranty Department, Locked Bag 66, Clayton Sth, Victoria,
3169. Claims received by post will take longer to process and
we encourage you to call. Bosch may refer you to one of its
Bosch Warranty Authorised Service Dealers.
Proof of purchase and purchase date, as well as proof of
installation and proper commissioning by a licensed installer,
may be required by Bosch or an authorised service technician.
All warranty service calls will be conducted by an authorised
service technician during normal business hours. Bosch will not
accept claims under this voluntary warranty for attendance and
repair of the Product by third parties not authorised by Bosch.
Deadlines for Submitting Warranty Claims
Bosch aims to rectify genuine quality problems as a priority.
This is generally achieved by investigating why defective
products have failed and by introducing immediate corrective
action measures to prevent re-occurring warranty failures.
It is therefore critical that all warranty claims are promptly
submitted to Bosch as soon as the product fails, and in any
event before the end of the warranty period.
Product Liability and Product Safety
Bosch should be informed immediately about any potential
product safety concerns within and outside the warranty
period. Bosch is well aware of its product liability and product
safety obligations and responsibilities. It is our aim to ensure
appropriate product safety standards are met in order to avoid
injury, loss and damage caused by defects in any Product.
If an end user does not wish to provide Bosch and/or its
authorised service technician with personal information, Bosch
may be unable to process the end user’s warranty claim or to
provide the end user with additional customer support, services
and information.
Bosch is committed to protecting the privacy of personal
information and will act in compliance with applicable privacy
laws, including the National Privacy Principles under the
Australian Privacy Act 1988 (Cth) (as amended) and New
Zealand’s Information Privacy Principles described in the
Privacy Act 1993 (NZ).
Bosch takes security measures in order to protect any personal
information collected in the warranty claim process against
manipulation, loss, destruction, access by unauthorised
persons or unauthorised disclosure.
Bosch will not disclose any personal information to third parties
other than for the Purpose or except as required by law.
An end user has the right to access the personal information
Bosch or its authorised service technician hold about them.

information held about them, or withdraw consent for its usage,
