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-1,2,3 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
