ADJUSTING

■	Keep cylinder away from heat. Rupture disc
	vents at 122° F. maximum.
■	Ventilate room after high pressure gas leakage.
■	Check the last DOT test date on cylinder neck
	before filling. If more than five years old, the
	cylinder must be retested to DOT specifications.
■	Be sure CO2 cylinder outlet fitting is free of dust
	or dirt before attaching regulator.
■	Store CO2 cylinder and regulator assembly
	upright.

Adjusting the CO2 Gas Flow

■Turn regulator adjusting screw counterclockwise until it turns freely.

■Turn hand valve counterclockwise on CO2 cylinder to the fully open position.

■Turn regulator adjusting screw clockwise until desired pressure is reached (approximately

12-15 lbs.). Tighten stop nut on adjusting screw.

■Open shut-off valve on bottom of regulator.

CO2 Leak Test

Dilute a small amount of liquid dishwashing soap and rub the soapy mixture around each connection. If bubbles appear, tighten connection.

Replacing CO2 Gas Cylinder

■Turn CO2 hand valve clockwise until seated and close shut-off valve on regulator.

■Connect cylinder directly to a keg without a regulator (reducing valve).

■Drop or throw regulator or CO2 cylinder.

■Transport CO2 cylinder in a closed vehicle.

■Apply oil to a regulator.

■Shut off CO2 cylinder when not in use. You will not save gas by doing so!

■Allow untrained, inexperienced personnel to

handle high pressure gas.

Failure to heed this warning could result in personal injury or death.
