NOTE:
These outdoor units may be used with indoor units
equipped with Thermostatic Expansion Valve or
Accutron rM FlOW Control Check Valve (EC.C. V) assembly
for refrigerant flow control only.
Check for transportation
damage after unit is uncrated.
Report promptly, to the carrier, any damage found 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
1. When removing unit from the pallet,
the basepan. Remove tabs by cutting
shown in Figure 2 (see page 2).

2. The unit 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".
3. The support pad must NOT be in direct contact with any
structure.
Unit must be positioned a minimum of 12"
from 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 Code. Also,
the unit location must be far enough away from any
structure to prevent excess roof run-off water from
pouring directly on the unit. Do not locate unit(s) close to
bedroom(s).

4,

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

for at least

5. 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.
6,

The maximum length of refrigerant
lines from outdoor
indoor unit should NOT exceed sixty (60) feet.

to

7. If outdoor unit is mounted above the air handler,
maximum lift should not exceed sixty (60) feet (suction
line). If air handler is mounted above condensing unit,
maximum lift should not exceed sixty (60) feet (liquid
line).
NOTE:
Refer to "Refrigerant

Piping Software"

Pub. No. 32-3312-02.

8. Locate and install indoor coil or air handler in accordance with instruction
included with that unit.

8,

To prevent a noise within the building structure
due to
vibration transmission
from the refrigerant
lines, the
following precautions
should be taken:
a. When the refrigerant
lines have to be fastened to floor
joists or other framing in a structure,
use isolation
type hangers.

C. ACCUTRON

TM

FLOW CONTROL

VALVE

If the indoor unit System Refrigerant
Flow control is an
Accutron TM orifice and check valve assembly, an orifice size
change may be necessary.
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
difihrent orifice size, the orifice must 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.

E. SERVICE

VALVE OPERATION

BRASS LIQUID AND GAS LINE SERVICE VALVES
The Brass Liquid and Gas Line Service Valves are factory
shipped in the seated position to hold factory charge. The
pressure tap service port (when depressed) opens only to the
field brazing side of the valve when the valve is in the seated
position.
The liquid line valve is not a back seating valve
(see WARNING below).

Extreme caution should be exercised when opening the
Liquid Line Service Valve. Turn valve stem counterclockwise only until the stem contacts the rolled edge. (See
Figure 4) No torque is required.
BRASS GAS LiNE BALL SERVICE VALVE
The Brass Gas Line Ball Service Valve is shipped in the
closed position to hold the factory refrigerant
charge. The
pressure tap service port (when depressed) opens only to the
field brazing side when the valve is in the closed position. The
Gas Line Ball Service Valve is full open with a 1/4 turn. See
Figure 5.
BRAZING REFRIGERANT LINES
1. Remove lower access cover to access service valves.

The gas line must always be insulated.

2. Before brazing, remove plugs from external copper stub
tubes. Clean internal and external surfaces of stub
tubes prior to brazing.

in scroll compressor applications, dome temperatures may
be hot. Do not touch top of compressor, may cause minor
to severe burning.

NOTE:
Precautions should be taken to avoid heat damage to

11. The gas valve can now be opened. Open the gas valve by
removing the shut-off valve cap and turning the valve
stein 1/4 turn counterclockwise,
using 1/4" Open End or
Adjustable wrench. See Figure 5.
12. The gas valve is now open for refrigerant
flow. Replace

If refrigerant
lines are longer than 15 feet and/or a
difthrent size than recommended,
it will be necessary to
adjust system refrigerant

components,
provisions are made for a field installed start kit
accessory. When adding an accessory, follow the instructions
provided with the kit.

AND CHECKOUT

Final phases of this installation
are the unit Operational
and
Checkout Procedures which are found in this instruction
(see
page 8). To obtain proper performance,
all units must be
operated and charge adjustments
made in accordance with
procedures found in the Service Facts.

6. The use of color coded low voltage wire is recommended
to simplify connections between the outdoor unit, the
thermostat
and the indoor unit.
Table 1 -- NEC Class tt Control

START UP

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.

K. OUTDOOR
