2.Operation down to zero airflow is satisfactory for all models.

3.Consult factory before operating at these velocities.

4.Efficiency is average and is based on ASHRAE Stan ard 52.1 test methods.

5.Performance tolerances conform to Section 7.4 of ARI Standard 850.

6.Actual filter face size is 5/8” under on height a d width. Actual filter depth is 5-7/8” or 11-1/2”
