RLDS Installation

Standard accessories needed for a four (4)-point Sys-

tem:

3.1. RLDS - Installation

Considerations

3.1.1. Warnings and Cautions

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

WARNING: Explosion hazard! Do not mount

or operate this equipment in an area that may
contain or in the presence of flammable



liquids, vapors, or aerosols. Operation of any electrical
equipment in such an environment constitutes a safety

hazard.

WARNING: Drilling holes in the RLDS



enclosure may damage the unit and will void
the warranty. Please use the knockouts



provided for electrical connections.

CAUTION: The RLDS contains sensitive



electronic components that can be easily



damaged. Do not to touch nor disturb any of

these components.
