Installation of Solar Tube Company Solar SPA Collector Kits

Warning

: Only install your system if you and any persons working with you are competent to do so,

and only after you have assessed all risks, and either eliminated them or reduced them to safe levels.

Caution

: There is a boiling risk, which is fully avoidable. Either fit the tubes at the end of the

installation after the system is filled or shade the tubes prior to commissioning.
