Choose a space that can support the weight of the cooler and economizer with service clearances and area for refrigerant piping. Field-supplied piping must be limited to less than 50 lineal ft (15.25 m) or 75 equivalent ft (22 m) in length. Suction and liquid line risers must be limited to less than 15 ft (4.5 m) vertical riser elevation. Suction lines and economizer lines must be insulated to prevent condensation. Relocating the cooler introduces minimal line losses if correct piping practices are followed. Buried lines are not permitted.

The remote cooler system can be applied in three different configurations. See Fig. 1-3. In Fig. 1, the remote cooler and the outdoor unit are at the same elevation. The suction, liquid, and economizer lines run parallel between the cooler and the outdoor unit. In Fig. 2, the outdoor unit and remote cooler are at the same elevation, but the interconnecting piping has an ele- vation of up to 15 ft (4.5 m) above the base elevation of the cooler. This could be result of running piping over a wall or through the ceiling in a building. In Fig. 3, the remote cooler is located below the outdoor unit. The interconnecting piping has an elevation of up to 15 ft (4.5 m) above the base elevation of the remote cooler. This could occur if the remote cooler is in- stalled in a basement.

NOTE: Unit 30XA refrigeration piping can be either copper tubing or steel tubing with flanged connections. All units are

factory charged with compressor oil to the required level. However, when the double riser is constructed with U-bends or street elbows, a substantial amount of oil can be trapped in the U-bend during prolonged minimum load operation. If this occurs, additional oil is needed to add to the system to prevent the oil level from dropping below the minimum level in the oil separator. Add 1 gallon of oil to each circuit. Refer to Controls, Start-up, Operation, Service, and Troubleshooting Guide for recommended oil type.
