WARNING
!
THIS INFORMATION IS FOR USE BY INDIVIDUALS HAVING ADEQUATE
BACKGROUNDS OF ELECTRICAL AND MECHANICAL EXPERIENCE. ANY
ATTEMPT TO REPAIR A CENTRAL AIR CONDITIONING PRODUCT MAY RESULT
IN PERSONAL INJURY AND/OR PROPERTY DAMAGE. THE MANUFACTURER
OR SELLER CANNOT BE RESPONSIBLE FOR THE INTERPRETATION OF THIS
INFORMATION, NOR CAN IT ASSUME ANY LIABILITY IN CONNECTION WITH
iTS USE.

CAUTION
!
EQUIPMENT DAMAGE! TO PREVENT SHORTENING ITS SERVICE LIFE, THE AIR
HANDLER SHOULD NOT BE USED DURING THE FINISHING PHASES OF CON-
STRUCTION 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.
1-1/2 – 4 Ton Air Handlers
Upflow / Horizontal Left
These instructions do not cover all variations in systems or provide for every possible
contingency. Should further information be desired or particular problems arise which
are not covered sufficiently by this manual, contact your local distributor or the manu-
facturer as listed on the air handler nameplate.
These Air Handlers are vertical upflow and horizontal left configuration only. Refer to
Section B beginning on page 2 for additional information.
INSPECTION
Check carefully for any shipping damage. This must be reported to and claims made
against the transportation company immediately. Check to be sure all major compo-
nents 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.
NOTE: Condensation may occur on the surface of the air handler when in-
stalled in an unconditioned location. When units are installed in unconditioned
spaces, verify that all electrical and refrigerant line penetrations on the air
handler are sealed completely.
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 (for models TGB3F42, 48A only) has been evaluated in accordance
with the Code of Federal Regulations, Chapter XX, Part 3280 or the equivalent. “SUIT-
ABLE FOR MOBILE HOME USE”
For proper installation the following items must be considered:
1. If adequate power is available and correct according to nameplate specifica-
tions.
2. Pursuant to Florida Building Code 13-610.2.A.2.1, this unit meets the criteria for
a factory sealed air handler.
3. Insulate and seal all ducts, particularly if unit is located outside of the condi-
tioned space.
4. 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 (available online) and Service Facts
(available online) for additional information.
5. 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 instal-
lation and possible future service.
6. The Refrigerant lines must be sealed and Electrical inlets need to be sealed at
both the low and the high voltage.
7. 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 the manufacturer. Only manufacturer-built
heaters are approved for use in the air handler. These heaters have been
designed and tested in accordance with UL standards to provide safe and reli-
able 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.
8. If field installed electric heaters are applied, minimum air flow settings, unit
and duct clearances to combustibles must be maintained as stated on the air
handler rating nameplate.
9. 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 & within condi-
tioned space.
10. If the outdoor unit is to be installed later, or by others, then installation of the air
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.
