Exceeding the maximum recommended pressure could cause personal injury or dam-
age the instrument.
These instructions refer to the installation of a gas line, regulator, and gas cylinder for
each type of gas used. If expansion kits or other accessories are used in the lab, spe-
cial consideration should be given to these configurations when installing the gas
lines.
Improper handling, disposing of, or transporting potentially hazardous materials can
cause serious bodily harm or damage to the instrument. Always refer to the SDS
when handling hazardous materials. Safe operation and handling of the instrument,
supplies, and accessories are the responsibility of the operator.
Place gas cylinders within 6 feet (2 m) of the gas inlets of the analyzer. Place the cylinders
n
close enough to allow for proper connection at the analyzer inlet.
Using gas line extenders on gas cylinders located in remote areas may degrade gas quality
and reduce pressure.
Long gas lines, such as those used with gas cylinders placed in remote areas, must be purged
for an extended period of time to remove ambient gases. When possible, avoid placing gas
cylinders in remote locations. It is always best to have gas cylinders located near the analyzer.
Use a retaining strap (or other appropriate tether) to secure the gas cylinder.
n
Always use the gas lines provided with the analyzer. It is very important that proper gas lines
n
are used with the analyzer.
o Do not use polymer tubing for the gas line.
Do not use flexible gas lines. Some flexible lines may appear to be appropriate, such as
o
those with a herringbone covering, but the line may be coated internally with a polymer.
Carefully route the gas lines from the cylinder to the analyzer avoiding overlapping or
n
entangling gas lines. This will help avoid confusion when maintenance is required.
Label the gas line at the analyzer inlet for proper identification and maintenance.
