WARNING
Improper installation, adjustment, alteration,
service or maintenance can cause property
damage, injury or death, and could cause
exposure to substances which have been
determined by various state agencies to cause
cancer, birth defects or other reproductive
harm. Read the installation, operating and
maintenance instructions thoroughly before
installing or servicing this equipment.
WARNING
This unit contains R-410A high pressure
refrigerant. Hazards exist that could result in
personal injury or death. Installation,
maintenance, and service must only be
performed by an HVAC technician qualified in
R-410A refrigerant and using proper tools and
equipment. Due to much higher pressure of
R-410A refrigerant, DO NOT USE service
