Notes:
2. A minimum clearance of 2' 4-1/2" is required to open the hinged
control panel doors on Casing 9, 90-130 ton units.
3. Increase the clearance between staggered units by 150% of the
minimum clearance for a single unit installation (i.e. 12' 0" clearance
for Casing 2-6, 20-75 ton units).
A minimum clearance of 16' 0" is required if the units are not staggered.
4. 4' minimum clearance for Casing 2-6, 20-75 ton units.
8' minimum clearance for Casing 9, 90-130 ton units.
Staggering the units:
a. minimizes span deflection which deters sound transmission; and
b. maximizes proper diffusion of the exhaust air before it reaches
the adjacent unit's fresh air intake.
