STEP 5
Detach the cold water closed circuit tube from the tank. Pour the solution slowly into the tube in
order to fill the collector. Let the liquid overflow through the outlet of the tank until no air bubbles
come out and then attach and tighten the cold fluid union to the tank. You may need to attach an
auxiliary tube to the cold water closed circuit tube so as to pour the solution from a point higher than
the closed circuit hot water inlet of the tank.
STEP 6
Complete filling the closed circuit with the solution from the safety valve outlet at the top of the tank.
