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:
!.
2.
3.
If adequate power is available and correct according
to nameplate specifications.
Insulate all ducts, particularly if unit is located
outside of the conditioned space.
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. ReferenceACCA
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 ad-
vance which knockouts are to be used, proper clear-
ance 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 combustible
flooring an accessory subbase (TAYBASE101 for
4TEP3F18-36A, TAYBASE 100 for 4TEP3F42A,
4TEP3F48-63B and TAYBASE102 on 4TEP3F48-63A)
must be used. See Figure 1.
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.
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:
ff air handier is used WITHOUT a supplementary electric
heater, a sheetmeta] 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.
