B.Second, disconnect CO2 quick disconnect from soft drink tank.

4.To connect soft drink tank into Unit syrup system.

A.First, connect CO2 quick disconnect to soft drink tank to pressurize tank.

B.Second, connect liquid quick disconnect to soft drink tank.

5.Disconnect inlet (CO2) and outlet (syrup) lines from empty soft drink tank.

6.Check soft drink tank quick disconnects for sticky or restricted operation. Rinse disconnects in warm water.
