Table 8 Technical characteristics

Water quality

All Bosch appliances are constructed from high quality materials and components and all are certified for compliance with relevant parts of Australian gas, electrical and water standards.

While Bosch water heaters are warranted against manufacturing defects, the warranty is conditional upon correct installation and use, in accordance with detailed instructions provided with the heater.

In the case of the water supplied to the heater, it is important that the water quality be of acceptable standard.

In regions where water is characterized by high chloride and calcium carbonate levels, it is essential to analyse it and, if necessary, treat the water to prevent eventual damage to appliance heating elements.

In the areas of Australia where water maybe supplied either fully or partly from bores, artesian wells, or similar, one or more of the important limits may well be exceeded and the heater could, therefore, be at risk of failure.

If the installer is uncertain about the water quality in the area, they should always contact the Bosch Customer Contact Centre Phone 1300 30 70 37 and request to speak with the technical team.

Alternatively, you can contact us using the online form at:
https://www.bosch-homecomfort.com/au/en/residential/customer-support/contact-us/

Or via post to:
Robert Bosch Aust Pty Ltd, Attention TT Warranty Department, Locked Bag 66, Clayton South, Victoria, 3169. Claims received by post will take longer to process and we encourage you to call.

If it is determined that the water supply does not meet quality standards, the Bosch warranty will not apply.

Environmental protection and disposal

Environmental protection is a fundamental corporate strategy of the Bosch Group.

The quality of our products, their economy and environmental safety are all of equal importance to us and all environmental protection legislation and regulations are strictly observed. We use the best possible technology and materials for protecting the environment taking account of economic considerations.

Packaging

• Polystyrene
  Clean polystyrene material may be recycled. Recycle, incinerate, or landfill, as appropriate, in an approved facility.
  Dispose of in accordance with Local, State & Federal EPA waste regulations.
  Polystyrene packaging is not recyclable in yellow recycling bins. May be landfilled in Australia.
  To confirm local practices, contact your local Council. For disposal locations visit https://recyclemate.com.au/ select material and location.
• Cardboard
  Dispose in your kerbside recycling bin or a dedicated cardboard recycling bin.
• Soft Plastic Wrapping
  Dispose of soft plastic wrapping packaging in your general waste bin.

Used appliances
Used appliances contain valuable materials that can be recycled.

The various assemblies can be easily dismantled. Synthetic materials are marked accordingly. Assemblies can therefore be sorted by composition and passed on for recycling or disposal.

Old electrical and electronic appliances

Do not dispose in your kerbside bins.

Electronic products can contain toxic chemicals and pose health and safety risks for the people handling your kerbside waste. They are a cause of contamination in kerbside bins and can pose a fire risk in collection trucks and at material recovery facilities.

Keep devices out of your kerbside bins and always safely dispose of them at a nominated collection point. If there are no options close to you for appropriate disposal, contact help@recyclemate.com.au for further guidance on appropriate disposal practices in your state or jurisdiction.
