Caravanning - Carver Cascade 2 water heaters and SB1800 heaters - manuals, some technical advice, repair details, testing gas systems and gas safety warnings.

Installation and user manuals - Read this page to discover all the information you can buy from my website - FAR more than just the pdf or jpg copies of manuals that many ebay sellers provide. If you want to print out a manual - just use the high quality pdf files. No other seller offers you a huge range of strip-down and repair photographs (although others have tried to steal and resell my photographs!).

Before you buy on ebay, please read the following email - it is typical of the thanks I receive. The SeeRed website contains far more caravanning technical information than you get from ebay sellers. It is written by a PhD scientist who just happens to have an interest in caravannning!

Hi Steve!

Thank you very much for your wonderfully helpful resource. It was well worth the money - unlike the 1.49 I paid for a copy of the Carver Trumatic SB1800 User Manual (from that rogue ebay user '
xxxxxx'), and actually received just an emailed, poor quality (diazo print) pdf file of the Fitting Instructions!
In view of the horrendous features of the SB1800 that you have brought to life, perhaps it should be re-named the 'Traumatic'!
Best wishes,

P.S. Your website is priceless!

Information includes full details of Carver SB1800 and Cascade 2 water heaters. Also some details of AL-KO towing hitches. This section of SeeRed was originally produced simply to be helpful to other caravan owners and to highlight the business practices of some dominant companies. Installation manuals are provided in various formats including high quality pdf - simply download the one most suitable for your needs.

READ THE GAS SAFETY NOTES ON MY WEBSITE BEFORE UNDERTAKING ANY WORK.
Only 'competent persons' must work on gas systems.


These pages, including over 50 detailed images and diagrams of strip down and repair procedures, used to be 'free to view' on the web - then certain individuals on ebay started stealing and selling the photos. Ebay were slow to react and the people involved did not have their accounts suspended. Furthermore, ebay refused to allow me to give my webpages away for free via their systems. Other sellers argued that as my webpages were free to view they could not be copyright - which is incorrect. However, in order to stop people profiting to excess, I have had to alter my website. The pages are no longer free but are for sale as genuine 'SeeRed' webpages and for a lot less money than the people made who stole them! If you know of my webpages and images being sold elsewhere please tell me about it. A few of the dozens of images available are shown below as small thumbnails.

A separate webpage details the unhelpful attitude of Truma (UK) towards owners of Carver heating products. Some material from the Patent Office is reproduced. A couple of patents on the Cascade 2 expired in January 2005 and new 'lookalike' units are now available, and despite everything that Truma and their lawyers tried to do to be unhelpful. More historical information will be added here later.

Almost everyone you speak to in the caravan world detests the high prices and/or non-availability of spares for many older products - in effect manufacturers are forcing consumers to buy whole new systems instead of a few reasonably priced spare parts. This is wholly against the tenets of reuse and recycling (an article on this is included on my website) yet, regrettably, a parallel situation exists in the automotive world generally.

Carver SB1800 heater - an example of poor installation. The Carver (Truma) SB1800 is one of the simplest caravan heaters. However, it suffers from some safety issues, the best known being corrosion of two steel gas pipes beneath floor level. These are the large pipe (supplying gas to the control valve) and the smaller one (feeding gas from the valve to the burner). The small pipe is the most likely to fail, and in the proximity of the burner. Many photos are available of repairs.

Carver Cascade 2 water heater - strip down and repairs: The photos on this page show a Carver Cascade 2 caravan water heater being stripped down. The common faults with these units include frost damage (which is often easily repaired), corrosion of the aluminium cylinder (which can often be repaired or if not, replaced) and failure of the central tie rod. Electronic failures in the burner module may mean a service exchange or new unit (about 100) but repairs can sometimes be effected (see below).

Gas leak testing for caravans and motor homes - procedures for competent owners. Low pressure leak testing of the fixed gas pipes in caravans is a good idea as part of annual servicing, and is readily undertaken at home if you know what you are doing (and if you don't know, then don't try it!). I use a standard set of procedures regularly. Commercial testing often costs 40 to 60 and consists of little more than a cursory inspection, a pressure check and the often unnecessary replacement of good quality flexible hoses. How to test these systems is outlined in detail. Remember -
