Maintenance:
Maintenance of the system is very easy and includes the following
tasks:
1. Cleaning
Regular rain should keep the evacuated tubes clean, but if
particularly dirty they may be washed with a soft cloth and warm,
soapy water or glass cleaning solution. If the tubes are not easily
and safely accessible, high pressure water spray is also effective.
2. Leaves
During autumn, leaves may accumulate between or beneath the tubes.
Please remove these leaves regularly to ensure optimal performance.
3. Broken tube
If a tube is broken it should be replaced as soon as possible to
keep the system working. Any broken glass should be cleared away to
prevent injury.
