9. Maintenance requirements
9.1. 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 safety accessible, high pressure water spray is also effective.
9.2. Leaves
During autumn days, leaves may accumulate between or beneath the tubes. Please
remove these leaves regularly to ensure optimal performance and to prevent a fire
hazard.
9.3. Broken tube
If a tube is broken it should be replaced as soon as possible to maintain maximum
collector performance. The system will still operate normally even with a tube broken.
Any broken glass should be cleared away to prevent injury.
To replace a tube:
1.
Remove the tube clip, slide broken tube out and carefully pick up any glass
pieces.
Please wear protective gloves when handling the broken glass
.
When removing the tubes, the rubber ring in the manifold casing may pop out.
Just return the ring into place before inserting the new tube.
2.
Avoid touching the glass wool insulation with bare hands, as it can cause mild
skin irritation.
3.
The new tubes should already have heat transfer fins inserted, so slide the new
tube into place taking care to guide the heat pipe into the slot between the fin
and the glass wall. Normally the heat pipe does not need to be removed from
the manifold.
