Identify Location for Monitor, Sample
Points and Alarms
Monitor Location:
ASHRAE-15 specifies
that the refrigerant monitor is to be located
in the mechanical room. There are two
interpretations of this: the unit itself is to be
installed in the mechanical room; or the
sample point is to be located in the
mechanical room. Because the IR-SNIF-
MCD is an active air draw monitor, it can be
installed nearly anywhere in the vicinity of
the area to be monitored.
If local codes allow, the monitor can be
installed at the entrance to the mechanical
room, with the sample tube routed into the
mechanical room and the fresh air
reference routed to an appropriate location.
If the monitor is located outside the
mechanical room, a fitting should be
installed and an exhaust tube routed either
into mechanical room, or outdoors. If it is
routed outdoors, it must not be located near
the fresh air reference.
If local codes require the monitor to be
physically installed in the mechanical room,
it should be installed in the best location for
ease of use and routing of sample and
fresh air tubing. If the monitor is installed in
the same room as the sample pick-up-point,
no exhaust tube is required.
Caution: Liquid can affect the
performance of the monitor. Pick-
up-points must be protected from
exposure to water and other
liquids.
Sample Location:
Since the monitor
measures the concentration of refrigerant in
