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 eighty (80) feet. to 7. If outdoor unit is mounted above the air handler, maximum lift should not exceed sixty (60) fhet (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. |nsta||er's Guide b. Isolation hangers should also be used -when refrigerant lines are run in stud spaces or enclosed ceilings. @ c. Where the refrigerant lines run through they should be insulated and isolated. a wall or sill, d. Isolate the lines from all ductwork. E. SERVICE VALVE OPERATION C. ACCUTRON TM FLOW CONTROL VALVE If the indoor unit System Refrigerant Flow control is an Aceutron TM orifice and check valve assembly, an orifice size change may be necessary. See Figure 3. 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 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 un# nameplate will have correct orifice size specified as BAYFCCV---A for rated performance. D. INSTALLING Condensing units REFRIGERANT have provisions The gas line must always be insulated. The units are factory charged with the system charge required when using fifteen (15) feet of connecting line. nameplate charge is the same. Final refrigerant charge adjustment is necessary. the Charging Charts in the outdoor unit Service Facts. 2. Consider FLARE FITTINGS 1. Remove gas and liquid line flare nuts from service valves and discard copper caps. 2, Cut and fit tubing minimizing the use of sharp 90 degree bends, for a even flare it is recommended that a tube cutter be used. A hacksaw should not be used to cut the tubing. 3, Remove any burrs from the inside edge of copper tubes with a deburring tool or knife. of outdoor The indoor end of the recommended refrigerant line sets may be straight or with a 90 degree bend, depending upon situation requirements. This should be thoroughly checked out before ordering refrigerant line sets. the most practical 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. LINES for flare connections. Pressure taps are provided on the service valves unit for compressor suction and liquid pressures. 1. Determine 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 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). Prior to assembling the faces for the following: a.

LEAK CHECK IMPORTANT: Replace pressure tap port valve core before attaching hoses for evacuation. After the installing of refrigerant lines to both the outdoor and indoor unit is completed, the field 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 leak-free! If not, release pressure; then repair! SYSTEM EVACUATION NOTE: Since the outdoor unit has a refrigerant liquid line valves must remain closed. 2. Attach appropriate hoses from manifold and liquid line pressure taps. 18-AC52D5-1 9.
