INTRODUCTION
The remote cooler mounting accessory permits indoor relo-
cation of the cooler from 30GTN, GTR, GUN, GUR units up
to 75 ft (22 m) away from the base unit. Relocating the cooler
introduces minimal line losses if correct piping practices are
followed. See Table 1 for the number of accessory packages re-
quired for each unit and for the package contents.
In addition to the parts supplied with the accessory package,
the following material must be field-supplied:
• refrigerant-grade liquid and suction line piping (length
determined by installation). See Table 2 for connection
sizes.
• pressure relief valves and fittings
