WARNINGS
• Only use with nitrogen gas (N2).
• The regulator is not to be used with liquid nitrogen.
• Do not modify the regulator. Doing so could result in personal injury.
• Do not over-pressurize the regulator. This could cause leakage, part damage or
personal injury due to bursting of pressure-containing parts.
• Keep the regulator clean and free of oil.
• Do not use a damaged regulator. Except for replacing the gauges, do not
attempt to repair the regulator.
• Failure to follow instructions can result in personal injury and/or damage to the
equipment.
• Do not install this regulator where service conditions can exceed the
specifi cations of any applicable local, state, or federal codes and regulations.
• Wear safety glasses and gloves.
REGULATOR CONNECTION AND USE
Note:
The nitrogen regulator can be used with a charging hose and leak testing
gauge assembly or a charging and testing manifold.
• Make sure the cylinder connection (1) is clean and free from damage.
• Turn the T handle (6) all of the way out (counter clockwise, looking from the
bottom).
• Open the output control valve (4) to release any pressure, and then close it.
• Install the nylon gasket or O-ring, if the connection requires one.
• Install the regulator onto the cylinder. Do not over tighten the nut on gasketed
connections.
• Connect the yellow charging hose (11) from the regulator to the leak testing
gauge assembly, making sure the ball valve connection (9) is closed.
(If using a manifold, connect the yellow charging hose (15) of the manifold to
the regulator.)
• Connect the other end of the leak testing gauge assembly (8) to the system.
(If using a manifold, connect the low side hose (14) from the manifold to the
system.)
• Slowly open the cylinder valve. The high side gauge (2) should read the
cylinder pressure.
• Adjust the regulator pressure by turning the T handle (6) clockwise until the
required pressure (based on the system’s refrigerant) is shown on the low side
(output) (3) pressure gauge.
NOTE:
This is a non-reliving regulator. To adjust the output pressure lower, some
nitrogen will have to be released from the output (e.g. with no hoses connected,
turn the T handle counter-clockwise, then open the output control valve and
close it. The output gauge should read a lower pressure.)
• If using the leak testing gauge assembly, turn the red needle to the required
refrigerant pressure.
