WARNING: Hazardous substance
When burned, Freon R22 refrigerant forms
Phosgene gas. If the chiller is placed in the
vicinity of equipment with combustible systems,
the combustion air intake must be ducted in
from the outside and sealed in such a manner
as to prevent any refrigerant from entering the
combustion chamber. Refer to the Material
Safety Data Sheet for Freon R22 included in the
Appendix. This sheet explains the potential haz-
ards and how to avoid them.
