Operation/Maintenance/Service
WARNING:
All systems contain 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.
IMPORTANT: Do not release refrigerant to the atmosphere! If required service
procedures include the adding or removing of refrigerant, the service technician
must comply with all federal, state and local laws. The procedures discussed in
this manual should only be performed by a qualified HVAC technician.
WARNING:
Improper installation, adjustment, alteration, service, or maintenance can cause
property damage, injury, or death. Read the installation, operation, and maintenance
