between indoor and outdoor units. These applications require
between indoor and outdoor units. These applications require
additional accessories and system modifications for reliable system
operation. The maximum allowable total equivalent length is 250
ft. (76.2 m). The maximum vertical separation is 200 ft. (60.96 m)
ft. (76.2 m). The maximum vertical separation is 200 ft. (60.96 m)
when outdoor unit is above indoor unit, and 60 ft. (18.29 m) when
the outdoor unit is below the indoor unit. Refer to Accessory
the outdoor unit is below the indoor unit. Refer to Accessory
Usage Guideline below for required accessories. See Longline
