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
4.All motors have internal line break overload
5.Terminals 1 thru 8 are for connection of control circuit from evaporator unit. (Terminals 4 and 8 are not used by some evaporator models . See Note 7). Wiring by others to be NEC Class 2 and sized for 1V maximum drop.
6.Connection to Terminals 3 and 7 is used for high head alarm input connection in evaporator unit.
7.Connection to Terminals 4 and 8 is required only on models with (HGBP) hot gas bypass control signal output in evaporator unit.
8.Wires 1, 5 and 9 are separately connected to the grounded side of the 24V Class 2 circuit. Do not connect them together.
