7. Slide the black rubber wind- blocking seals up the tube until the lip on the seal is flush with the 

tank. 
8. Insert all tubes to achieve alignment of the tank and the frame before fastening the frame nuts 

and bolts. 
9. Once fully assembled tighten all nuts and bolts. 

 

      

 

 

 

Precautions: 

1. Do not assemble in the sun unless the glass tubes are covered, the heat pipes can get hot 

enough to cause a burn injury, and damage to the heat pipes will occur if the hot end of the pipe 
contacts cold water. Only uncover the glass tubes once the tank is filled with water. 

2. Do not bend, distort or crush the copper heat pipe. 
3. Do not allow the copper joint of heat pipe to impact on the evacuated tubes during installation 

4. Do not untwist the copper joint of the heat pipe; it was sealed in the factory, and allowing the 
liquid inside to escape will render the heat pipe useless.
