Johnson Controls AD-1252 Installation Instructions Manual

AD-1252 Thermal Dispersion Probe Airflow Measuring
System
Installation Instructions
Applications
The AD-1252 Thermal Dispersion Probe Airflow
Measuring System is an air-measurement device that
uses thermal dispersion technology to measure the
airflow velocity and temperature in duct and plenum
applications. Insertion probes are typically installed in
retrofit applications but may also be specified on new
construction projects.
The product may be used in rectangular, oval, or round
applications when installed in accordance with this
installation manual. Use behind a rain hood, in front of
an outside air damper, return air duct, downstream of a
fan discharge, or in the exhaust duct.
North American Emissions Compliance
United States
This equipment has been tested and found to
comply with the limits for a Class A digital device
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference when this equipment is
operated in a commercial environment. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications.
Operation of this equipment in a residential area is
likely to cause harmful interference, in which case
the user will be required to correct the interference
at his/her own expense.

Installation
IMPORTANT: Do not connect CAT5e cable to a
router between the DMPR-RA002 Electronic
Controller and thermal dispersion probes. Failure to
connect the cables directly from the DMPR-RA002
Electronic Controller to the thermal dispersion
probes may cause equipment damage.
IMPORTANT: In addition to these instructions, the
installation contractor shall comply with all local and
International codes and standards to ensure proper
and safe installation.
The thermal dispersion probes and electronic controller
ship in separate containers. Remove the thermal
dispersion probes and the electronic controller from the
shipping containers and inspect the devices for
damage before installation.
Installing the Thermal Dispersion Probes
The sensor density is based on extensive lab testing to
optimize the accuracy of the electronic controller.
When installing the thermal dispersion probes, use the
Square Duct Mounting, Round Duct Mounting, and
Oval Duct Mounting sections to determine the proper
spacing between each probe within the opening.
Contact your local Johnson Controls® representative if
you have questions regarding a particular application.
WARNING: Risk of Electric Shock.
Disconnect the power supply before making
!
electrical connections. Contact with
components carrying hazardous voltage can
cause electric shock and may result in severe
personal injury or death.
AVERTISSEMENT : Risque de décharge
électrique.
Débrancher l'alimentation avant de réaliser
tout branchement électrique. Tout contact
avec des composants conducteurs de
tensions dangereuses risque d'entraîner une
décharge électrique et de provoquer des
blessures graves, voire mortelles.
