damage after unit is uncrated.
Report promptly, to the carrier, any damage fbund to the
unit.
To determine
the electrical power requirements
of the
unit, refer to the nameplate
of the unit. The electrical
power available
must agree with that listed on the
nameplate.

B. LOCATION & PREPARATION
OF THE UNIT
1. The trait should be set on a level support pad at least
as large as the unit base pan, such as a concrete slab.
If this is not the application
used please refer to
application
bulletin "Trane APB2001-02".
2. The support pad must NOT be in direct contact with
any structure.
Unit must be positioned
a minimum
of
12" fi_om any wall or surrounding
shrubbery
to insure
adequate
airflow. Clearance
must be provided in front
of control box (access panels) & any other side requiring service access to meet National
Electrical
(?ode.
Also, the unit location must be far enough away from
any structure
to prevent excess roofrun-offwater
from
pouring directly on the unit. Do not locate unit(s) close
to bedrooln(S).

3. The top discharge
area must be unrestricted
least five (5) feet above the unit.

fi)r at

4. When the outdoor unit is mounted
on a roof, be sure
the roof will support the unit's weight.
Properly
selected isolation is recommended
to prevent
sound or
vibration
transmission
to the building structure.
5. The maximum
length ofrefi'igerant
lines f?om outdoor
to indoor unit should NOT exceed eighty (80) feet.
6. If outdoor unit is mounted
above the air handler,
maxfinmn
lil_ should not exceed eighty (80) feet (suction line). Fair handler is mounted
above condensing
unit, maximum
lif_ should not exceed sixty (60) feet
(liquid line).
NOTE:
Refer to "Refrigerant

an orifice
size change may be necessary.
See Figure 2.
The outdoor model determines
the required
orifice size.
Check the listed orifice size on nameplate
of the selected
outdoor model. If the indoor unit is factory shipped with a
different orifice size, the orifice nmst be changed to obtain
system rated performance.
iMPORTANT:
The outdoor unit is shipped with the proper size orifice and a
stick-on orifice size label in an envelope attached to the
outdoor unit. Outdoor unit nameplate will have correct orifice
size specified as BAYFCCV---A for rated performance.

Precautions
should be taken to avoid heat damage to

HEATERS

After all electrical wiring is complete, SET THE THERMOSTAT SYSTEM SWITCH IN THE OFF POSITION
SO
COMPRESSOR
WILL NOT RUN, and apply power by
closing the system main disconnect
switch.
This will
activate the compressor
sump heat (where used). Do not
change the Thermostat
System Switch until power has
been applied for one (1) hour. Following this procedure
will
prevent potential compressor
overload trip at the initial
start-up.

Electric heaters,
if used, are to be installed
in the air
