7. Open tank lid to ensure the circulation
of the air.
Caution: Monitor fluid level in the tank and,
if necessary, refill heat transfer fluid to
prevent air entering the solar circuit.

Check at the inspection window of the
filter or through the tank opening if
there are still air bubbles in the heat
transfer fluid. Continue flushing until
there is no air remaining in the fluid.
