Installation, Refrigerant Piping Install piping according to standard accepted refrigeration practice. The following recommendations should be adhered to: Use only refrigeration-grade copper tubing. Soft solder joints are not acceptable. Put dry nitrogen through lines while brazing. Do not leave dehydrated piping or components open to the atmosphere any longer than is necessary. Figure 6. Leg assembly (horizontal airflow, models 024-133; 5-26) Figure 8 Figure 7 Electrical Wiring The electrical installation should be in accordance with National Electrical Code, local codes and regulations. Proper overcurrent protection should be provided for the fan motors. Wiring diagrams shown are only basic and do not show fuses, disconnect switches, etc., which must be provided in the field. All standard motors have internal inherent overload protectors. Contactors can be used instead of starters requiring thermal protectors, eliminating the problem of furnishing the proper heating elements. All air-cooled condensers are furnished with either single- phase or three-phase fan motors, identified by the unit data plate. Three-phase motors must be connected to three-phase power voltage to agree with motor and unit data plate. The motors must be checked for proper rotation. Be sure to check that motor voltage and control connection agree with electric services furnished. The motors are wired into a common junction box. Where fan cycling is furnished and factory installed, the motors are completely wired through the control and to the contactors. Electrical leads from each motor terminate at the unit junction box. Field connections must be made from these leads through a contactor, fuse and disconnect in accordance with local, state and national codes. Table 1.

Line sizes based on pressure drop equivalent to 1°F per 100 equivalent feet. Values in table are based on 105°F condensing temperature. Multiply table capacities by the factors in Table 2 for other condensing temperatures. If subcooling is substantial or the line is short, a smaller line size may be used. Applications with very little subcooling or very long lines may require larger sizes. Table 2. Condensing Temperature Correction Factor Temp.
