A. GENERAL
The following instructions cover TTB012-024C; Condens-
ing Units.
NOTICE:
These outdoor units may be used with indoor units
equipped with Thermostatic Expansion Valve or
Accutron TMFlow Control Check Valve (F.C.C.V,) assem-
bly for refrigerant flow control only,
Check for transportation 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 requir-
ing 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).
@5 FT. ABOVE UNIT-UNRESTRICTED
3. The top discharge area must be unrestricted fi)r at
least five (5) feet above the unit.
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 (suc-
tion line). Fair handler is mounted above condensing
unit, maximum lif_ should not exceed sixty (60) feet
(liquid line).
NOTE:
Refer to "Refrigerant Piping Software" Pub. No, 32-3312-02.
|nstaller's Guide
7. Locate and install indoor coil or air handler in accor-
dance with instruction included with that unit.
C. ACCUTRON TM FLOW CONTROL VALVE
If the indoor unit System Refl'igerant Flow control is an
Accutron TM orifice and check valve assembly, 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.
D. INSTALLING REFRIGERANT LINES
if using existing refrigerant lines make certain that all
joints are brazed, not soldered.
Condensing units have provisions for braze connections.
Pressure taps are provided on the service valves of outdoor
unit fbr compressor suction and liquid pressures.
The indoor end of the recommended refl'igerant line sets
may be straight or with a 90 degree bend, depending upon
situation requirements. This should be thoroughly
checked out before ordering refl'igerant line sets.
The gas line nmst always be insulated.
in scroll compressor applications, dome temperatures
may be hot. Do not touch top of compressor, may cause
minor to severe burning.
The units are factory charged with the system charge
required when using fil_een (15) feet of connecting line.
Unit nameplate charge is the same.
Final refrigerant charge adjustment is necessary.
Use the Charging Charts in the outdoor unit Service Facts.
1. Determine the most practical way to run the lines.
2. Consider types of bends to be made and space limitations.
NOTE:
Large diameter tubing will be very difficult to rebend
once it has been shaped,
3. Determine the best starting point lbr routing the
refl'igerant tubing- -INSIDE OR OUTSIDE THE
STRUCTURE.
4. Provide a pull-thru hole of sufficient size to allow both
liquid and gas lines.
5. Be sure the tubing is of sufficient length.
6. Uncoil the tubing -- do not Mnk or dent.
7. Route the tubing making all required bends and
properly secure the tubing bel[bre making connections.
8. To prevent a noise within the building structure due
to vibration transmission from the refrigerant lines,
the fbllowing precautions should be taken:
a. When the refrigerant lines have to be fastened to
floor joists or other l?aming in a structure, use
isolation type hangers.
b. Isolation hangers should also be used when reS"ig-
erant lines are run in stud spaces or enclosed
ceilings.
c. Where the refl'igerant lines run through a wall or
sill, they should be insulated and isolated.
d. Isolate the lines fl'om all ductwork.
E. SERVICE VALVE OPERATION
BRASS LiQUiD AND GAS LiNE SERVICE VALVES
The Brass Liquid and Gas Line Service Valves are lactory
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 counterclock-
wise only until the stem contacts the relied edge. (See
Figure 4) No torque is required.

BRAZING REFRIGERANT LINES
1. Befbre brazing, remove plugs fl'om external copper
stub tubes. Clean internal and external surfaces of
stub tubes prior to brazing.
2. Cut and fit tubing, minimizing the use of sharp
90 ° bends.
3. Insulate the entire gas line and its fittings.
4. Do NOT allow uninsulated liquid line to come in
direct contact with bare gas line.
5. 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.
NOTICE:
Use care to make sure that no moisture enters pressure
tap port, while wet rag is being used.
NOTICE:
Precautions should be taken to avoid heat damage to
basepan during brazing. It is recommended to keep the
flame directly off of the basepan.
6. Use a Dry Nitrogen Purge and Brazing Alloy without
flux when brazing the field line to the copper factory
connection. Flow dry nitrogen into either valve
pressure tap port, thru the tubing and out the other
port while brazing.
7. Braze using accepted good brazing techniques.
8. Leave heat shield in place while brazing to prevent
damaging the paint finish with torch. See Figure 4.
Discard the heat shield when finished with brazing.
LEAK CHECK
IMPORTANT:
Replace pressure tap port valve core before attaching hoses
for evacuation.
After the brazing operation of refi'igerant lines to both the
outdoor and indoor unit is completed, the field brazed
connections nmst be checked for leaks. Pressurize through
the service valve ports, the indoor unit and field refl'iger-
ant lines with dry nitrogen to 350-400 psi. Use soap
bubbles or other leak-checking methods to see that all field
joints are leak-fl'ee! If not, release pressure; then repair!

SYSTEM EVACUATION 11.
NOTE:
Since the outdoor unit has a refrigerant charge, the gas
and liquid line valves must remain closed, 12.
1. Upon completion of leak check, evacuate the refi'iger-
ant lines and indoor coil before opening the gas and
liquid line valves.
2. Attach appropriate hoses from manifold gauge to gas
and liquid line pressure taps.
NOTE:
Unnecessary switching of hoses can be avoided and
complete evacuation of al! lines leading to sealed system
can be accomplished with manifold center hose and
connecting branch hose to a cylinder of HCFC-22 and
vacuum pump,
3. Attach center hose of manifold gauges to vacuum
pump.
4. Evacuate until the micron gauge reads no higher than
350 microns.
5. Close offvalve to vacuum pump and observe the
micron gauge. If gauge pressure rises above 500 microns
in one (1) minute, then evacuation is incomplete or
system has a leak.
6. If vacuum gauge does not rise above 500 microns in
one (1) minute, the evacuation should be complete.
7. With vacuum pump and micron gauge blanked oft; open
valve on HCFC-22 cylinder and charge refl'igerant lines
and indoor coil with vapor to tank pressure of HCFC-22
supply.
NOTE:
DO NOT VENT REFRIGERANT INTO THE ATMOSPHERE.
8. (?lose valve on HCFC-22 supply cylinder. Close valves
on manifold gauge set and remove refl'igerant charg-
ing hoses from liquid and gas pressure tap ports.
NOTE:
A 3/16" Allen wrench is required to open liquid line
service valve. A 1/4" Open End or Adjustable wrench is
required to open gas line valve. A 3/4" Open End wrench
is required to take off the valve stem cap.
9. The liquid line shut-offvalve can now be opened.
Remove shut-off valve cap. Fully insert hex wrench
into the stem and backout counterclockwise until valve
stem just touches rolled edge (approximately five [5]
turns) observing WARNING statement on page 2. See
Figure 3.
10. Replace liquid service pressure tap port cap and valve
stem cap. These caps MUST BE REPLACED to
prevent leaks. Replace valve stem cap and pressure
tap cap finger tight, then tighten an additional
1/6 turn.
The gas valve can now be opened. Follow the same
procedures as you did for opening liquid valve as
outlined in steps 9 and 10 above. See Figure 3.
The gas valve is now open for refl'igerant flow. Re-
place valve stem cap to prevent leaks. Again, these
caps MUST BE REPLACED to prevent leaks.
Replace valve stem cap and pressure tap cap finger
tight, then tighten an additional 1/6 turn. See
Figure 5.
Ifrefi'igerant lines are longer than 15 feet and!or a
different size than recommended, it will be necessary
to adjust system refrigerant charge upon completion of
installation. See unit Service Facts.
