SOL Perpetua™ System Installation - Soldering Flux

We recommend the use of the water soluble flux we enclose with your order because it can be flushed out of a completed system with water. The cleaner the system is, including the working fluid, the longer its life will be and the less frequently gas must be removed from the bubble pump.

Without the pump in place flush out the system including the collector panels with water. Then, with the pump in place, flush with a non-toxic, non-corrosive chemical such as trisodium phosphate in a mixture of about two teaspoons (l/3 ounce) to a gallon of water. Fill the system with the cleaning mixture and, if there is no danger of freezing, allow to operate one full sunny day. Drain the cleaning mixture, rinse with clean water and refill with the final working fluid.

Piping in the vicinity of the bubble pump should be hard copper so that added support for the pump will not be needed.
