Unit Labeling
Labels are applied to each terminal as follows:
• Unit specific nameplate showing model number, manufactured date, and information regarding controls and heat
provided as appropriate.
• The appropriate airflow calibration chart indicating the airflow at varying airflow sensor signals as shown on pages
10, 11, and 12.
• The appropriate wiring/piping diagram for controls provided by Anemostat. Refer to controls manual CM-1 for
controls adjustment and troubleshooting procedures.
• Up arrow indicating the proper orientation of the unit for installation.
