mp
lies with the unit
nameplate specifications.
Visually inspect the exterior of the unit, including the
roof,
for signs of shipping damage.
Visually inspect the internal
c
omponents for shipping

ar long-sleeved,
loose-fitting clothing, gloves, and eye protection.
• Wash clothes separately from other clothing: rinse
washer th
orou
ghly.
• Operations such as sawing, blowing, tear-out, and
spraying
may generate fiber concentrations requiring
additional respiratory protection. Use the appropriate
NIOSH approved respiration in these situations.
First Aid Measures
Eye Contact
Flush eyes with water to remove dust. If symptoms persist,
seek medical attention.
Skin Contact
Wash affected areas gently with soap and warm water
after handling.
Storage
Take precautions to prevent condensate from forming
inside the unit’s electrical compartments and motors if:
• the unit is stored before it is installed; or,
• the unit is set on the roof curb,
and tempor
ary heat is
provided in the building. Isolate all side panel service
entrances and base pan openings (e.g., conduit holes,
S/A and R/A openings, and flue openings) from the
ambient air until the unit is ready for startup.
Note: Do
not use the unit’s heater for temporary heat
without first completing the startup procedure
detailed in “Startup,” p. 52.
The manufacturer will not assume any responsibility for
equi
pment damage resulting from condensate
accumulation on the unit’s electrical and/or mechanical
components.
