Warning: DO NOT ASSEMBLE IN STRONG SUNLIGHT!
If you assemble solar collectors under strong sunshine, or the ambient temperature is high, it’s forbidden to touch the
two copper pipes’ ends by hand directly. Once tubes are exposed to sunlight, they immediately begin to work. The
heat will be transferred to the top of the heat pipes in seconds. Therefore, the two ends of the copper pipes will
become very hot after you finish the assembly. Touching either pipe directly will scald your skin! You also can cover
the tubes with a blanket to avoid this hazard.
Fig 3.19
Suggestions:
1.
The assembly process is best finished in the shade.
2.
If the process has to be finished under sunshine, you can cover the inserted tubes by a black cloth, etc.
4.
Lightning protection
The solar water heater should have lightning protection to avoid lightening damage. A lightning rod is necessary
which should be 1.5m higher and 3 m farther away from the solar water heater. For any problems that involve
plumbing or electrical connections the services of a qualified professional must be employed.

How to connect a couple of collectors?
We suggest you use the corrugated connection pipe to connect two or more solar collectors. It is very
convenient and allows for easy alignment between two solar collectors. Please see the following picture.
