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 onl y.

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.

5.Terminals 1,2,3, and 4 are for connection of control circuit from evaporator unit. Wiring by others to be NEC Class 2 and sized for 1V maximum drop.

6.Wire '1' is connected to the grounded side of the 24V Class 2 circuit.
