REGULATOR MAINTENANCE

A dual stage, spring loaded regulator is employed for the pressure building/economizer

circuit. This regulator can be adjusted on the container, replaced or checked and adjusted

off the container in a readily fabricated bench adjustment fixture.

Regulator Adjustment  On Container

1. Fill the container with the appropriate liquid product.

2. Open the Pressure Building Valve and allow the container pressure to stabilize for

about an hour. Note the point where the pressure stabilizes.

3. Adjust the screw on the top of the regulator to raise or lower the pressure to the

desired point. When decreasing the setting, the pressure building valve must be closed

and the container vented to a lower pressure. Then repeat step 2 in order to observe

the change.

CAUTION

When changing gas

service, install the

proper fittings  DO NOT

use adapters. The

following procedures

address the physical

changes to the container

only. For detailed

procedures on the

decontamination of the

container itself, refer to

CGA pamphlet C-10

Changes of Service for

Cylinders Including

Procedures for

Inspection and

Contaminant Removal.

CAUTION

Carbon Dioxide and

Nitrous Oxide may

contain contaminants

such as hydrocarbons,

that are not easily

removed from cylinders,

and associated with

components by

conventional oxygen

service cleaning

procedures. Once a

cylinder is placed into

or N

O gas service, it

should never be

converted to another gas

service. See CGA

pamphlet C-10 for proper

procedures.

NOTE:

One clockwise turn of

the adjustment will raise

the setpoint by

approximately 30 psig (2

bar/207 kPa). See the

chart below to

determine the range of

adjustment for the

regulator you are

servicing. Do not attempt

to set the regulator to a

pressure outside of its

design range.
