1. Make sure cylinder valve “A” is closed.
2. Unscrew (counter clockwise) regulator key “B” as far out
as it will go. (The regulator is now in the off position).
3. Remove regulator from empty cylinder at “D”.
4. Remove dust cap from new cylinder at “D”. Open and
close valve “A” quickly to blow dust from outlet.
5. With cylinder valve “A” in closed position, re-attach
regulator to cylinder at “D”.
6. Open valve “A” all the way. (This is important because
this cylinder valve seals in two places).
7. Screw regulator key “B” in (clockwise) until required
pressure is reached “E”.
NOTE: Drinks will not pour if outlet valve “A” is closed.
