Definition of Statements
Statements in these instructions preceded by the following words are of special significance.
WARNING:
Means there is a possibility of injury or death to yourself or others.
CAUTION:
Means there is a possibility of damage to unit or other property.
NOTE:
Indicates points of particular interest for more efficient and convenient operation.
Installation
Isolation Valves shall be installed at specified
locations per NFPA 99, Standard for Health Care
Facilities or CAN/CSA-Z305.1, Canadian Standard for
Nonflammable Medical Gas Piping Systems. All
valves are supplied clean for oxygen service. Valve is
supplied with gas service identification decals.
NOTE:
Care shall be taken to keep debris out of valves
and medical gas pipeline during and after
installation.
Step 1: Location
Allow sufficient space to accommodate valve and
permit handle to turn 90 degrees without obstruction.
Step 2: Installation & Brazer Requirements
Isolation valves shall be installed using methods
and procedures that maintain interior cleanliness of
piping system as required by NFPA 99, Standard for
Health Care Facilities or CAN/CSA-Z305.1, Canadian
Standard for Nonflammable Medical Gas Piping
Systems. Brazing shall be performed by individuals
who are qualified in accordance with either Section IX,
Welding and Brazing Qualifications, of the ASME
Boiler and Pressure Vessel Code, or AWS B2.2,
Standard for Brazing Procedure and Performance
Qualifications.

Step 3: Socket Brazing Fittings
Shallow sockets are recommended to be used for
brazing fittings that comply with MSS SP-73, Brazing Joints
for Copper and Copper Alloy Pressure Fittings. Use of
shallow socket brazing fittings improves quality of
brazement without decreasing its strength, particularly in
larger sizes which are more difficult to heat.
Step 4: Brazing Joints
Braze valve tube extensions to medical gas piping
system using brazing filler metals that comply with
ANSI/AWS A5.8, Specification for Brazing Filler Metal. Use
appropriate heat sink techniques (e.g. heat absorbing paste,
water saturated fabric or continuous cooling medium) to
protect sealing materials in valve or gauge port plugs.
Unbolting and removing center valve section is not
recommended. During brazing, joints shall be continuously
purged with oil-free dry nitrogen to prevent formation of
copper oxide on inside surface of joint. Flow of nitrogen
purge gas shall be maintained until joint is cool to touch.
CAUTION:
Excessive heat may destroy valve sealing material. If
damage occurs to valve, a repair kit must be installed.
Refer to Isolation / Zone Valve Repair Kits listed in this
instruction.
