No, it would be very dangerous to attempt to do this. The panel is situated on the roof and there are no user serviceable parts inside. The heat transfer pipe is filled with a glycol solution and reaches a maximum working pressure of 600kPa. The heat transfer pipe reaches temperatures in excess of boiling point so, for example touching it, will cause severe burns. Treat it with the same caution as you would treat a pan of boiling water.
Yes, the system will work in much colder temperatures than we experience in this country. However, it will not work if the panel is covered in snow as this will prevent light striking the absorber plate. Some of our collectors are fitted to Alpine Hotels where really cold weather is experienced and they work perfectly in conditions of up to minus 30 degrees Celsius.
Nothing. If snow collects on the glass surface of the collector it will rapidly melt. In fact the design is such that it will melt more rapidly from the collector surface than it will melt from other parts of your roof.
There is no need to. They will not significantly impair performance and when it next rains they will be washed off.
Very little. Inside keep an eye on the pressure gauge on the pumping station. It should be around 3 to 5 bar.
Fluctuations in the course of use are quite normal but if the gauge shows no pressure please contact your installer.
Every month you should check visually that nothing has gone wrong outside. Every three years the integrity of the glycol can be checked and tested. Vacuum panels should be checked for the quality of the vacuum every two years and re-evacuated every five years

Turn off the electricity supply to the digital controller and the pump and then call your Installer on the telephone number located in your Logbook, on page 16.
No -it is better to keep it on.
Although they work best in direct sunlight, very good performance will be given in the indirect light (or diffuse radiation) of a cloudy day.
No, the system only works in daylight. At some times of the year there is insufficient daylight and that is why your system has a fossil fuel back up that will cover your needs at these times.
Glycol has to be used to prevent the pipe freezing in very cold weather. It is not dangerous – it is a type of anti freeze, but unlike normal anti-freeze it is classified in Europe and the USA as ‘edible’ and is safe for use in food. The Glycol is in a well engineered sealed system and will not leak into the domestic water supply.
Your Genersys Solar Hot Water System produces no emissions whatsoever. It is entirely without any discharge of greenhouse gases or other pollution.
We estimate that your system will save one ton of carbon dioxide a year which is equivalent to about a large sack of soot each year. Over the life of the system each system will save dozens of tons.
Yes it was but the energy used in manufacturing the system will be recovered after only two years use in this country (less in sunnier hotter countries).
