Length shown is as measured 1 way along wire path between unit and service panel for voltage drop not to exceed 2%.
** Time---Delay fuse.
FLA --- Full Load Amps
LRA --- Locked Rotor Amps
MCA --- Minimum Circuit Amps
RLA --- Rated Load Amps
NOTE : Control circuit is 24---V on all units and requires external power source. Copper wire must be used from service disconnect to unit.
All motors/compressors contain internal overload protection.
Complies with 2010 requirements of ASHRAE Standards 90.1
