• Cooling approach > 2.8oC (5oF)

• Process fluid temperature < 51.7oC (125oF)

• Barometric pressure

91.4 to 105.0 kPa (27” to 31” Hg)

STD-201 CERTIFICATION LIMITATIONS

• Unique Product Line Name & Model Numbers

• Applies to Only Product Lines & Models Submitted

• Installed With Ample Unobstructed Air Supply

• Multi-cell Systems Allowed if Airflow is Unaffected

Or Configuration Impact is Included in Ratings

• Optional Accessories Allowed if Airflow is Unaffected

Or Their Impact is Included in Ratings

• Non-certified Configurations or Locations

Should Consider ATC-105 Acceptance Test
