{
If wire is applied at ambient greater than 30 ˚ C (86 ˚ F), consult table 310---16 of the NEC (ANSI/NFPA 70). The ampacity of non---metallic---sheathed cable
(NM), trade name ROMEX, shall be that of 60 ˚ C (140 ˚ F) conditions, per the NEC (ANSI/NFPA 70) Article 336---26. If other than uncoated (no---plated), 60
_
or 75 ˚ C (140
_
or 167 ˚ C) insulation, copper wire (solid wire for 10 AWG or smaller, stranded wire for larger than 10 AWG) is used, consult applicable tables
of the NEC (ANSI/NFPA 70).

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 2001 requirements of ASHRAE Standards 90.1
