1. All units 208/230V, 1 phase. On 208/230V units installed
in Canada only, CSA requires that L1 and L2 are non-neutral
supply conductors. L1 et L2 pour conducteurs d'alimentation
non-neutres. On other units, L2 is designated neutral. See
unit name plate and installation manual for main supply wiring
information. Use copper conductors only.
2. Use copper conductors only. See unit nameplate for main supply
wire sizing data. Wire per local codes.
3. A remote disconnect switch is to be field-supplied and mounted
within sight of the condensing unit. See unit nameplate for voltage
and amperage requirements.
4. All motors have internal line break overload protectors.
Three-phase motors protected for primary single-phasing conditions.
