WARNING: Shock hazard! Always
de-energize the power supply before working
on the interior of the equipment.
CAUTION: The RLDS contains sensitive
electronic components that can be easily
damaged. Do not to touch nor disturb any of
these components.
3.1.2. Inspection
The RLDS has been thoroughly inspected and
tested prior to shipment from the factory.
Nevertheless, it is recommended that the monitor be
re-checked prior to installation. Inspect the outside of
the enclosure to make sure there are no obvious signs
of shipping damage. Open the enclosure and inspect
the interior of the unit for loose components that may
have become dislodged during shipment. If damage is
discovered, please contact Technical Support for
assistance (770-425-2724).
3.1.3. Monitor Location
The RLDS should be centrally located in the
facility and should be easily accessible for visual
monitoring and servicing. Intake sample lines can be
up to 1200 feet (365 meters), but it is important to
remember that sampling cycle time is proportional to
the total number and length of individual sample
lines.
Dirt, grease, and oils can adversely affect the
operation of the RLDS. The monitor should be
installed out of direct sunlight in a clean, dry area that
is not subject to temperature or humidity extremes.
Installation of the monitor in a mechanical room is
acceptable provided reasonable environmental
conditions exist. If there is a question, consider
installing the unit outside of the mechanical room in a
cleaner area of the facility. The location should allow
the monitor to be easily accessible for visual
monitoring and servicing.
3.2. RLDS Mounting
Instructions
3.2.1. Screw Locations
The RLDS should be installed plumb and level and
securely fastened to a rigid mounting surface. The
enclosure utilizes keyhole mounting brackets
