Important: Environmental Concerns! Scientific research has shown
that certain man-made chemicals can affect the earth's naturally occurring
stratospheric ozone layer when released to the atmosphere. In particular,
several of the identified chemicals that may affect the ozone layer are
refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those
containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all
refrigerants containing these compounds have the same potential impact
to the environment. Trane advocates the responsible handling of all
refrigerants-including industry replacements for CFCs such as HCFCs and
HFCs.
Important: Responsible Refrigerant Practices! Trane believes that
responsible refrigerant practices are important to the environment, our
customers, and the air conditioning industry. All technicians who handle
refrigerants must be certified. The Federal Clean Air Act (Section 608) sets
forth the requirements for handling, reclaiming, recovering and recycling of
certain refrigerants and the equipment that is used in these service
procedures. In addition, some states or municipalities may have additional
requirements that must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.

Description
Auto
In Auto mode, the indoor unit automatically sets the temperature and fan
speed to maintain the selected temperature. If the indoor temperature is
too high, a cooling breeze is generated until the room returns to a
comfortable level. As the room cools, the fan slows down and maintains
a gentle airflow.
Cool
In Cool mode, the temperature setpoint, fan speed, and air flow direction
on the indoor unit can be controlled.
Dry
In Dry mode, the unit dehumidifies the indoor air.
Fan
In Fan mode, the unit ventilates the area to maintain a comfortable indoor
environment.
Heat
In Heat mode, the temperature setpoint, fan speed, and air flow direction
on the indoor unit can be controlled.
Notes:
• There may be a delay before the fan begins running to avoid
generating a cold breeze.
• The defrost indicator (Defrost) appears when frost is being removed
from the outdoor unit. When the defrost function is completed, the
defrost indicator disappears.
• After heating operation is stopped, the fan continues running for a
period of time to cool the unit.
