Additional Unit Preparation - Trane TAM7A0A24H21SC Installer's Manual

Additional Unit Preparation Considerations
For proper installation the following items must be
considered prior to moving the unit to its installation
site:
• Pursuant to Florida Building Code 13–610.2A.2.1,
this unit meets the criteria for a factory sealed air
handler.
• If a side return is needed for your application, the
side return MUST be prepared prior to moving the
air handler to its installation location. See the Side
Return Kit #BAYSRKIT100A Installer Guide for
detailed instructions.
• When the air handler is located adjacent to the
living area, the system should be carefully designed
with returns which minimize noise transmission
through the return air grill. Although the air handler
is designed with large blowers operating at
moderate speeds, any blower moving a high
volume of air will produce audible noise which
could be objectionable when the unit is located very
close to a living area. It is often advisable to route
the return ducts under the floor through the attic.
Such design permits the installation of air return
remote from the living area (i.e. central hall).
• Study the unit's outline drawing and dimensions
prior to selecting the installation site. Note in
advance which electrical conduit entry points and
condensate drain holes are to be used, so that
proper clearance allowances can be made for
installation and future maintenance.
• Installation of the air handler must be made prior to
, or at the same time as, the installation of the
outdoor unit in order to allow access for refrigerant
lines.

• Consider the overall space needed when external
accessories are used, additional height and width
requirements may exist.
• These units are not approved for outdoor
installation.
• These units must be installed in the proper air flow
direction.
• Any third-party heater accessories or hydronic coils
must be downstream of the unit.
N N o o t t e e : : No atomizing style humidifier is allowed in the
return plenum with the use of this unit.
• Excessive bypass air may cause water blow-off,
which will adversely affect system operation and air
cleaner performance. To verify bypass airflow,
follow the Bypass Humidifier Pre-Installation
Checkout and Set-Up Procedures available through
your local distributor. Ask for publication number
