General Warnings and Cautions
"!
WARNING
1. The Ultima X Series Gas Monitors described in this manual
must be installed, operated and maintained in strict
accordance with their labels, cautions, warnings,
instructions, and within the limitations stated.
2. The Ultima X Series Gas Monitor is designed to detect
gases or vapors in air. It cannot measure the
concentration of gases or vapors in steam or inert or
oxygen-deficient atmospheres. The oxygen sensor can
measure oxygen-deficient atmospheres.
3. Electrochemical sensors are sealed units which contain a
corrosive electrolyte. Should a sensor develop leakage, it
must be immediately removed from service; then, remove
it from the sensing head and discard it properly. Caution
must be exercised so that the electrolyte does not contact
skin, eyes, clothing or circuitry; otherwise, serious
personal injury (burns) and/or equipment damage may
result.
4. Use only genuine MSA replacement parts when performing
any maintenance procedures provided in this manual.
Failure to do so may seriously impair instrument
performance. Repair or alteration of the Ultima X Series
Gas Monitor, beyond the scope of these maintenance
instructions or by anyone other than an authorized MSA
service personnel, could cause the product to fail to
perform as designed and persons who rely on this product
for their safety could sustain serious personal injury or
death.
5. Do not locate the general-purpose enclosure models in an
area which may contain a flammable mixture of gas and
air; otherwise, an explosion may occur. The
general-purpose Ultima X Series Gas Monitors can be a
source of ignition and must not be mounted in an area
where a flammable mixture of combustible gas and air
may become present; otherwise, an explosion may occur.
If such a location must be monitored, use an
explosion-proof Ultima X Series Gas Monitor model.
6. The Ultima XIR Infrared combustible gas monitor detects
the presence of most combustible gases by identifying the
difference in the amount of infrared light energy absorbed
during the presence of these gases. This monitor,
