EQUIPMENT DAMAGE! TO PREVENT SHORTENING ITS SERVICE
LIFE, THE AIR HANDLER SHOULD NOT BE USED DURING THE
FINISHING PHASES OF CONSTRUCTION OR REMODELING. The
low return air temperatures can lead to the formation of condensate.
Condensate in the presence of chlorides and fluorides from paint,
varnish, stains, adhesives, cleaning compounds, and cement creates
a corrosive condition which may cause rapid deterioration of the
cabinet and internal components.

The following warning complies with State of California law, Proposition 65.
This product contains fiberglass wool insulation! Fiberglass dust and ceramic
fibers are believed by the State of California to cause cancer through
inhalation. Glasswool fibers may also cause respiratory, skin, or eye irritation.
PRECAUTIONARY MEASURES:
--Avoid breathing fiberglass dust.
--Use NIOSH approved dust/mist respirator.
--Avoid contact with the skin or eyes. Wear long sleeved, loose fitting
clothing, gloves and eye protection.
--Wash clothes separately from other clothing; rinse washer thoroughly.
--Operations such as sawing, blowing, tear-out, and spraying may generate
fiber concentrations requiring additional respiratory protection. Use the
appropriate NIOSH approved respirator in these situations.
FIRST AID MEASURES
--Eye contact: Flush eyes with water to remove dust. If symptoms persist,
seek medical attention.
--Skin Contact: Wash affected areas gently with soap and warm water after
handling.
These instructions do not cover all variations in systems or provide for
every possible contingency. Should further information be desired or

Check to be sure all major components are in the unit. Any missing
parts should be reported to your supplier at once, and replaced with
authorized parts only.
INSTALLATION LIMITATIONS & RECOMMENDATIONS
The general location of the air handler is normally selected by the
architect, contractor and/or home owner for the most effective
application and satisfaction.
These air handlers are suitable for installation in a closet, alcove or
utility room with free, non-ducted, air return, using the area space as a
return air plenum. With ducted supply air, if the minimum clearances to
combustible materials and service access are observed, the above
installations are suitable.
This area may also be used for other purposes, including an electric
hot water heater - but in no case shall a fossil fuel device be
installed and/or operated in the same closet, alcove or utility
room.
In addition, these air handlers are suitable for installation in an attic,
garage or crawl space with ducted supply and return air.
This equipment has been evaluated in accordance with the Code of
Federal Regulations, Chapter XX, Part 3280 or the equivalent.
"SUITABLE FOR MOBILE HOME USE"
For proper installation the following items must be considered:
1. If adequate power is available and correct according to name-
plate specifications.
2. Insulate and seal all ducts, particularly if unit is located outside of
the conditioned space.
3. To ensure maximum efficiency and system performance, the
existing supply and return duct system static pressures must not
exceed the total available static pressure of the air handler.
Reference ACCA Manual D, Manual S and Manual RS along with
the air handler Product Data and Service Facts for additional
information.
4. It is recommended that the outline drawing be studied and
dimensions properly noted and checked against selected
installation site. By noting in advance which knockouts are to be
used, proper clearance allowances can be made for installation
and possible future service.
5. If supplementary heat is to be added, power supply must be
sufficient to carry the load. In addition, minimum air flow settings,
unit and duct clearances to combustible material must be
maintained as stated on the air handler rating nameplate.

For air handlers not equipped with a factory installed electric heater,
a field installed heater is available from Trane. Only heaters built by
Trane are approved for use in the air handler. These heaters have
been designed and tested in accordance with UL standards to
provide safe and reliable operation. A list of approved heaters is
provided on the air handler rating nameplate. Heaters that are not
factory approved could cause damage and are not covered under
equipment warranty.
