Installation
General
Install the Aspirated Sampling Module in the correct area classified in
your facility.
• The explosion-proof model hazardous area classification is
Class I, Division 1, Groups A, B, C and D. It is important that all
local and national codes be followed when installing this model in a
classified area.
Double check the area classification of the sampling module. Refer to
FIGURE 1-2 to find the area classification label on your unit. Ensure
that the Ultima X Gas Monitor is rated properly by referring to Ultima X
Gas Monitor instruction manual (P/N 10036101) for more details.
Do not mix units with different area classifications. All units
used in a classified area must have the proper area classifi-
cation. Otherwise, an explosion hazard will exist, resulting in
a possible explosion, injury or death.
The sampling module for a general-purpose (GP) monitor
can be a source of ignition. Install, locate and operate only
in a non-hazardous area and in accordance with applicable
codes.
If sampling from or exhausting into a separate location, the
installation requires flashback arrestors at the inlet from a
hazardous location and at the outlet to a hazardous location,
to prevent the propagation of ignition of hazardous gases.
Routinely check for aspirated system leaks that could create
an explosive environment inside the enclosure.
Read and follow all instructions, warnings and cautions per-
taining to this gas monitor.
FAILURE TO FOLLOW THIS WARNING CAN CAUSE
IGNITION OF EXPLOSIVE ENVIRONMENTS RESULTING IN
SERIOUS PERSONAL INJURY OR DEATH.
