II modular air processing systems contain either chlorodifluoromethane
(HCFC-22) or a hydro-fluorocarbon blend (HFC-407C). HCFC-22 is believed
to harm the public health and environment by destroying ozone in the
upper atmosphere. Do not release HCFC-22 to the atmosphere. The
U. S. Clean Air Act requires the recovery of any residual refrigerant.

Improper installation, adjustment, alteration, service, or maintenance can cause
property damage, injury, or death. Read the installation, operation, and maintenance
