This information is intended for use by individuals possessing adequate backgrounds of electrical and mechanical
experience. Any attempt to repair a central air conditioning
product may result in personal injury and or property

Units.
NOTE:
These outdoor units are designed to be installed with
approved/matched Trane indoor systems.
These units use R-410A refrigerant which operates at 50 to
70% higher pressures than R-22. Use only R-410A approved
service equipment. Refrigerant cylinders are painted a
"Rose" color to indicate the type of refrigerant and may
contain a "dip" tube to allow for charging of liquid refrigerant into the system. All R-410A systems use a POE oil that
readily absorbs moisture from the atmosphere. To limit this
"hygroscopic"
action, the system should remain sealed
whenever possible. Never break a vacuum with air and
always change the driers when opening the system for
component replacement.
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 AND PREPARATION
OF THE UNiT
1. When removing unit from the pallet, notice the tabs on
the basepan. Remove tabs by cutting with a sharp tool as
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 XR-APG**-EN".

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 BA YFCCV---A for rated pefformance.
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 ff'ont of
control box (access panels) & any other side requiring
service access to meet National Electrical Code. Also,
the unit location must be fhr 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

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

After the brazing operation of refrigerant
lines to both the
outdoor and indoor unit is completed, the field brazed
connections must be checked for leaks. Pressurize
through
the service valve ports, the indoor unit and field refrigerant
lines with dry nitrogen to 350-400 psi. Use soap bubbles or
other leak-checking
methods to see that all field joints are

VALVE OPERATION
BRASS LIQUID LINE SERVICE VALVE
The Brass Liquid Line Service Valve is thetory shipped in the
seated position to hold thctory 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 SERVICE VALVE
The Brass Gas Line Service Valve is shipped in the closed
position to hold the rectory 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 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.
2. Before brazing, remove plugs from external copper stub
tubes. Clean internal and external surIhces of stub
tubes prior to brazing.
3. Cut and fit tubing, minimizing
90 ° bends.
4. Insulate
the entire
the use of sharp
gas line and its fittings.
5. Do NOT allow uninsulated
contact with bare gas line.
6. Precautions
should be taken to avoid heat damage
to the pressure
tap valve core during
brazing.
It is
recommended
that the pressure
tap port valve
core be removed
and a wet rag wrapped
around
the valve body.
1. Upon completion of leak check, evacuate the refrigerant
lines and indoor coil before opening the gas and liquid
line valves.
