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
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.

Inspection
• Unpack all components of the kit.
• Check carefully for any shipping damage. If any damage is found it must
be reported immediately and a claim made against the transportation
company.
• Visually inspect the components for shipping damage as soon as
possible after delivery, before it is stored. Concealed damage must be
reported within 15 days.
• If concealed damage is discovered, stop unpacking the shipment.
• Do not remove damaged material from the receiving location. Take
photos of the damage, if possible. The owner must provide reasonable
evidence that the damage did not occur after delivery.
• Notify the carrier’s terminal of damage immediately by phone and by
mail. Request an immediate joint inspection of the damage by the
carrier and the consignee.
Important:
Do not attempt to repair any damaged parts until the parts are
inspected by the carrier’s representative.
Important Safety Instructions
General Safety Instructions
• Do not store combustible materials, gasoline or other flammable
vapors and liquids near the unit.
• Should overheating occur, or the gas supply fail to shut off, shut off the
manual gas valve to the furnace before shutting off the electrical supply.
• Do not use this furnace if any part has been under water. Immediately
call a qualified service technician to inspect the furnace and to replace
any part of the control system and any gas control system and any gas
control which has been under water.
• Never perform any maintenance procedures until the electrical power
and/or gas supply to the unit has been turned off.
• Never remove any panels from the unit while it is operating.
• Never remove panels or parts from this unit that are not discussed in
this manual.
• Never cover the unit, since it is designed to operate year-round.
• The furnace area must be kept clear and free of combustible materials,
gasoline and other flammable vapors and liquids.
• For proper and safe operation the furnace needs air for combustion and
ventilation. Do not block or obstruct air openings on the furnace, air
openings communicating with the areas in which the furnace is
installed, and the spacing around the furnace.
At installation and the beginning of each heating season, a qualified service
technician should examine the furnace to ensure:
• All flue products carrying areas external to the furnace, (i.e., chimney,
vent connector, etc.), are clear and free of obstructions.
• The physical support of the furnace is sound and without sagging,
cracks, gaps, etc., around the base so as to provide a seal between the
support and the base.
• There are no obvious signs of deterioration of the furnace.
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.
• Do not touch any electric switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor’s phone. Follow the
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
indicate the approximate room temperature, and a temperature scale at the
adjustment indicator to select the desired indoor air temperature. In
addition, most controls have a selector mode switch with Heat, Off and Cool
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 automatically when the selector switch is
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. (In new homes, check the filters every week for the first 4 weeks.)
See
Table 1
for the required filter size(s).
If you have disposable type filters, replace them with new filters of the same
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:
It may be necessary to replace permanent filters 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.
