Precautionary Measures
WARNING
Fiberglass Wool!
Product contains fiberglass wool. Disturbing the
insulation in this product during installation,
maintenance or repair will expose you to airborne
particles of glass wool fibers and ceramic fibers known
to the state of California to cause cancer through
inhalation. You MUST wear all necessary Personal
Protective Equipment (PPE) including gloves, eye
protection, a NIOSH approved dust/mist respirator, long
sleeves and pants when working with products
containing fiberglass wool. Exposition to glass wool
fibers without all necessary PPE equipment could result
in cancer, respiratory, skin or eye irritation, which could
result in death or serious injury.
•
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.

•
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.

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 start-up.
Note: Do not use the unit's heater for temporary heat
without first completing the start-up procedure
detailed under

The manufacturer will not assume any responsibility for
equipment damage resulting from condensate
accumulation on the unit's electrical and/or mechanical
components.
