6. 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.
CAUTION
!
For air handlers not equipped with a factory installed
electric heater, a field installed heater is available from
American Standard Inc. Only heaters built by American
Standard Inc. are approved for use in the air handler.
These heaters have been designed and tested in accor-
dance 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.
NOTE:
If air handler is used WITHOUT a supplementary electric
heater, a sheetmetal plate is required to cover the open
hole in the airflow system. See Figure 2. Also seal the
cabinet air tight where the wire enters.
7. If field installed electric heaters are applied, mini-
mum air flow settings, unit and duct clearances to
combustibles must be maintained as stated on
the air handler rating nameplate.
8. If the unit is installed without a return air duct,
applicable local codes may limit this air handler to
installation only in a single story residence and
within conditioned space.
9. If the outdoor unit is to be installed later, or by
others, then installation of the air handler must be
made to allow access for refrigerant lines, or attach
refrigerant lines to air handler when installing.
10. Make sure there are provisions for installing
condensate drain lines.
This area may also be used for other purposes, includ-
ing 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 installa-
tion 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
nameplate specifications.
2. Insulate all ducts, particularly if unit is located
outside of the conditioned space.
3. 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
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. When air handler with supplementary heater is to
be installed in the downflow position on combus-
tible flooring an accessory subbase (TAYBASE101
for 2TEC3F18-36A, TAYBASE102 for 2TEC3F55
and TAYBASE100 for 2TEC3F42A-60A) must be
used. See Figure 1.
