All phases of this installation must comply with NATIONAL, STATE AND LOCAL CODES. Should further information be desired or should particular problems arise which are not covered sufticiently for the purchaser's purposes, the matter should be referred to your installing dealer or local distributor. STATE is to remain @ AND with this LOCAL unit. CODES Please return to service 5 FT. ABOVE UNIT-UNRESTRICTED A. GENERAL The following ing Units. instructions cover TTB012-024C; Condens- 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,) assembly 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 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 Piping Software" Pub. No, 32-3312-02. |nstaller's Guide 7. Locate and install indoor coil or air handler in accordance with instruction included with that unit. C. ACCUTRON FLOW CONTROL TM 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. 6. Uncoil the tubing 8. To prevent a noise within to vibration transmission the fbllowing precautions 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 unit fbr compressor suction and liquid pressures. b. Isolation hangers should also be used when reS"igerant 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. always 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). of outdoor 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 the building structure due from the refrigerant lines, 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. E. SERVICE D. INSTALLING -- do not Mnk or dent. 7.

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 tap port, while wet rag is being used. 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'igerant 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! HEAT SHIELD enters pressure 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. 18-AC30D10-2 3 |.staller's Guide SYSTEM EVACUATION NOTE: Since the outdoor unit has a refrigerant charge, and liquid line valves must remain closed, 1.

NOTE: DO NOT VENT REFRIGERANT INTO THE ATMOSPHERE. 11. 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. 12. The gas valve is now open for refl'igerant flow. Replace 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 installation. See unit Service Facts.

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.

COMPRESSOR START UP I. ELECTRIC Guide 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 handling device according to the instructions accompanying the air handler and the heaters. H.
