006-020 can be stored 3 units high. Vertical units Size 006-
and 5 units high with one. Do not stack units Size 030 and
larger.
A registered professional engineer must design and approve the air
conditioner and air handler application to make sure smoke and fume
control meet local re codes and NFPA requirements for the specic
building application. Due to the wide variation in building design and
ambient operating conditions into which our products can be applied,
we do not represent or warrant that our products will be t and sufcient
for smoke and fume control and management purposes. The owner and
building designer must consult a registered professional engineer to satisfy
themselves in this regard.
The system design and installation must follow accepted
industry practice, such as described in the ASHRAE
Handbook, the National Electric Code, and other applicable
standards. The installation of this equipment must be in
accordance with regulations of authorities having jurisdiction

before leaving the factory. Install units carefully to
prevent damage.
3. All fans are dynamically balanced before leaving the
factory. Carefully inspect fans for rough handling that can
cause misalignment or a damaged shaft.
4. Horizontal units Size 006-020 may be stacked 3 units
