Notes:

1. Placement on a level surface free of obstructions (including snow, for winter operation) or air recirculation ensure rated performance, reliableoperation, and ease of maintenance. Site restrictions may compromise minimum clearances indicated below, resulting in unpredictable airpatterns and possible diminished performance. Johnson Controls’ unit controls will optimize the operation without nuisance high pressure safe-ty cutouts: however, the system designer MUST consider potential performance degradation.

2. Access to the unit control center stipulates the unit is no higher when on spring isolators. Recommended minimum clearances: side to wall - 6';rear to wall - 6'; control panel end to wall - 4'; top - no obstructions whatsoever; distance between adjacent units - 10'. No more than one adja-cent wall may be higher than the unit.
