Installer's Guide
FOR AIR HANDLERS NOT EQUIPPED WITH A FACTORY
INSTALLED ELECTRIC HEATER, A FIELD INSTALLED
HEATER IS AVAILABLE FROM THE DEALER. ONLY
HEATERS BUILT BY TRANE ARE APPROVED FOR USE
IN THE AIR HANDLER. These heaters have been de-
signed 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 name-
plate. Heaters that are not factory approved could
cause damage and are not covered under equipment
warranty.
INSTALLATION LIMITATIONS & RECOMMENDATIONS
The general location of the Air Handler is normally se-
lected 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, includ-
ing an electric hot water heater - but in no ease 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 installa-
tion in an attic, garage or crawl space with ducted sup-
ply 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 con-
sidered:
1. If adequate power is available and correct according
to nameplate specifications.
2. Insulate all ducts, particularly if unit is located out-
side of the conditioned space.
3. Pursuant to Florida Building Code 13-610.2.A.2.1,
this unit meets the criteria for a factory sealed
Air Handler.
.
.
.
To ensure maximum efficiency and system perfor-
mance, 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 ad-
ditional information.
Penetration around the Refrigerant lines must be
sealed and Electrical inlets need to be sealed at
both the Low and the High Voltage.
It is recommended that the outline drawing be stud-
ied and dimensions properly noted and checked
against selected installation site. By noting in ad-
vance which knockouts are to be used, proper clear-
ance allowances can be made for installation and
possible future service.
