Cautions, Warnings and Notices
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
forththerequirementsforhandling,reclaiming,recoveringandrecyclingof
certain refrigerants and the equipment that is used in these service
procedures. In addition, some states ormunicipalities mayhave additional
requirements that mustalso be adheredto for responsible management of
refrigerants. Know the applicable laws and follow them.

WARNING
Safety Instructions!
Failure to follow instructions in this section could result in death, serious
injury, and property damage.
Safety Instructions Before Operating the Unit
• This appliance does not have a pilot. It is equipped with an ignition
device which automatically lights the burner. Do not try to light the
burner by hand.
• BEFORE OPERATING smell all around the appliance area for gas. Be
sure to smell next to the floor because some gas is heavier than air and
will settle on the floor.
What To Do If You Smell Gas
• Do not try to light any appliance.
• Donot touchanyelectricswitch;donotuse any phonein your building.
• Immediatelycallyour gassupplier from a neighbor’sphone.Followthe
gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
Temperature Control Devices
Room thermostats and zone sensors are delicate temperature control
devices.
Thermostats’ main function is to energize and de-energize the heating or
cooling circuit to maintain the temperature setting you select.
Zone sensors’ main function is to sense the room temperature to allow the
unit controls to activate the heating and cooling functions to maintain the
temperature setting you select.
Many thermostats and zone sensors contain a room thermometer to
indicatetheapproximateroomtemperature,andatemperaturescaleatthe
adjustment indicator to select the desired indoor air temperature. In
addition,mostcontrolshaveaselectormodeswitchwithHeat,OffandCool
positions, and a fan switch with On and Auto positions.
When the selector switch is positioned at Off, your unit will not operate in
either the heat or cool modes. If the selector switch is set at Heat, the unit
will automatically cycle on and off to maintain the desired temperature
setting.The unit will also operate automaticallywhen the selector switchis
positioned at Cool.
The fan selector switch can be used to operate the indoor fan continuously
by positioning it at On. When set at Auto, the fan will only operate when
required during the heating or cooling cycles.
To ensure that the thermostat or zone sensor operates properly, it must be
level and positioned to avoid the influence of such external heat sources
such as lamps, televisions or other heat producing appliances.
Air Filters
It is very important to keep the central duct system air filters clean. Be sure
to inspect them at least once each month when the system is in constant
operation.(Innewhomes, checkthefilters everyweekforthe first 4 weeks.)
See Table 1 for the required filter size(s).
Ifyouhavedisposabletypefilters,replacethemwithnew filtersofthesame
type and size. Do not attempt to clean disposable filters.
Permanent type filters can be cleaned by washing them with a mild
detergent and water. Ensure that the filters are thoroughly dry before
reinstalling them in the unit (or duct system).
Note: Itmay be necessaryto replace permanentfilters annually if washing
fails to clean the filter, or if the filter shows signs of deterioration. Be sure
to use the same type and size as was originally installed.

Heating System
Heating Cycle Operation
A normal heating cycle begins when the air temperature in your home
drops below the selected setting. The control then energizes the heating
electrical circuit that starts and controls the main burners. Shortly after the
main burners ignite, the indoor fan starts and circulates warm air through
your home, or building.
When the air temperature rises to the selected setting, the control de-
energizestheheatingelectricalcircuitwhich,inturn,extinguishes the main
burners. The indoor fan continues to circulate warm air until most of the
heat is removed from the unit’s combustion chamber.
Safety Controls
Your unit is equipped with automatic reset safety limit controls to prevent
overheating. When one of these controls open, it shuts down the heating
electrical circuit until it cools down sufficiently. Inadequate airflow (i.e.,
caused by dirty air filters or a defective fan motor) may cause the unit to
cycle on and off as the limit controls trip and automatically reset. If you
suspect that the unit is cycling on its limit controls, immediately contact a
serviceman for instructions.
