Storing the Unit

surface. Moisture, debris, and minerals can cause permanent
damage to the cabinet and components. Do not allow
coverings to trap moisture on the galvanized surface.
When in a warehouse (i.e. not in transit), horizontal units Size
006-020 can be stored 3 units high. Vertical units Size 006-
020 can be stored 6 units high without an external filter rack,
and 5 units high with one. Do not stack units Size 030 and
larger.

Smoke Control and Management
Systems
Improper smoke or fume air handling can result in severe
personal injury or death.
A registered professional engineer must design and approve the air
conditioner and air handler application to make sure smoke and fume
control meet local fire codes and NFPA requirements for the specific
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 fit and sufficient
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
Handbook, the National Electric
standards. The installation of this equipment must be in
accordance with regulations of authorities having jurisdiction
and all applicable codes. It is the responsibility of the installer
to determine and follow the applicable codes.
