Precautionary Measures
•
Avoid breathing fiberglass dust.
•
Use a NIOSH approved dust/mist respirator.
•
Avoid contact with the skin or eyes. Wear long-
sleeved, loose-fitting clothing, gloves, and eye
protection.
•
Wash clothes separately from other clothing: rinse
washer thoroughly.
•
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.

Take precautions to prevent condensate from forming
inside the unit’s electrical compartments and motors if:
1. the unit is stored before it is installed; or,
2. the unit is set on the roof curb, and temporary 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
