NOTES:
1. Placement on a level surface free of obstructions (including snow, for winter operation) or air recirculation ensures rated performance,
reliable operation and ease of maintenance. Site restrictions may compromise minimum clearances indicated below, resulting in unpre-
dictable air flow patterns and possible diminished performance. YORK’s unit controls will optimize operation without nuisance high pres-
sure safety cutout; however, the system designer must consider potential performance degradation. Access to the unit control center
assumes the unit is no higher than on spring isolators. Recommended minimum clearances: Side to wall - 6'; rear to wall - 6'; control
panel end to wall - 4'; top - no obstructions allowed; distance between adjacent units - 10'. No more than one adjacent wall may be higher
than the unit.
