* Permissible limits of the voltage range at which the unit will operate satisfactorily
{ If wire is applied at ambient greater than 30_C, consult table 310- 16 of the NEC (NFP A 70). The ampacity of non- metallic- sheathed cable (NM), trade
name ROMEX, shall be that of 60_C conditions, per the NEC (NFPA 70) Article 336- 26. If other than uncoated (no- plated), 60 or 75_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 (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 2010 requirements of ASHRAE Standards 90.1
