designed for 1/4” (6.35 mm) fasteners. Locate the
four screws as shown in the diagram below and allow
the screw heads to protrude approximately

1/4” (6.35 mm).
3.2.2. Installation
Hold the monitor flat against the mounting surface
and allow it to slide down, engaging the screw heads
in the keyhole slots of the mounting brackets. Adjust
the screws as necessary to hold the monitor securely
against the mounting surface.
3.3. RLDS - Connecting Air
Lines
3.3.1. Overview
Individual sample lines are run from the RLDS to
each area of the facility to be monitored. Additionally,
a purge line is installed to provide clean air for

resetting the infrared zero baseline. An exhaust line is
installed to vent residual gas away from the monitor.
All air line connections, located on the left side of the
enclosure, are indicated in Figure 3-3 .
3.3.2. Tubing Considerations
Use 1/4” (6.35 mm) outside diameter (0.04” wall)
(1.02 mm wall) flex tubing for all air lines or

equivalent. The tubing should be clean and free of

residual moisture or other contaminants. The tubing
should be cut cleanly with a sharp knife and care
should be taken not to distort the tubing end.
To connect the air lines to the monitor simply push the
tubing firmly onto the connector. To remove a line,
depress the plastic ring on the connector with one
hand while withdrawing the tube with your other
hand. All tubing bends should have a radius of no less
than 5” (12 cm) to ensure proper airflow. If kinks or
obstructions occur in any of the air lines, the

instrument may not function properly.
3.3.3. Connecting Purge Line
A purge line is required to draw fresh air into the in-
strument and should not exceed 300 feet (91 meters)
in length. A charcoal filter assembly has been

Mounting Instructions
Four 1/4 inch fasteners are required to mount
the RLDS enclosure. Allow approximately
1/4 inch of each fastener to remain exposed.
The enclosure can slide directly onto the
screw heads for mounting. Verify the position
of enclosure on the fasteners, and then
tighten all fasteners.
