WARNING
WARNING
Fiberglass Wool!
WARNING: ALL INSULATED UNITS
(except closed-cell foam insulation)
CONTAIN FIBERGLASS WOOL! Read
this literature prior to installation for
proper instruction. 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. Glass
wool fibers may also cause respiratory,
skin or eye irritation.
