The insert shows regulator 5580922, while the tank is shown with regulator 11729749. • With regulator 11729749, an adapter must be used to connect hose assembly to low pressure port of regulator. Use a right or left-hand threaded 9/16 X 18 NF adapter, depending on thread requirements of the hose assembly coupling. 4 Attach hose assembly (5) to low pressure port (6). 5 Shut off pressure regulator valve (7) by rotating counterclockwise. NOTE If pressure indicated is less than 100 psi (690 kPa), replace tank. 6 Open shutoff valve (2) slowly. Adjust until maximum tank pressure registers on high pressure gage (8). NOTE Gages labeled 0–15 psi, 0–30 psi, or 0–60 psi are authorized but must be in 1 psi increments. 7 Rotate pressure regulator valve (7) slowly clockwise until approximately 5 psi (34 kPa) registers on low pres- sure gage (9). 7 8 6 6 5 7 2 8 9
