HFC-410A refrigerant. The units can be suspended from
the ceiling in a horizontal position or installed on the wall
near the
fl
oor in a vertical position.

WARNING
!
Improper installation, adjustment, alteration, ser vice
or maintenance can cause property damage, personal
injury or loss of life.
Installation and service must be performed by a li-
censed professional HVAC installer, service agency
or the gas supplier.
Failure to follow safety warnings and these instruc-
tions exactly could result in property damage, dan-
gerous operation, serious injury, or death.
Any additions, changes, or conversions required in

plication needs must be made by a licensed profes-
sional HVAC installer (or equivalent) using factory-

Do not use this system if any part has been under

gerous. Immediately call a licensed professional
HVAC service technician (or equivalent) to inspect
the system and to replace all controls and electrical
parts that have been wet, or to replace the system, if
deemed necessary.
