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.
