Option/Accessory Wiring
To indicate common potential
only; not to represent wiring.
NOTES:
1. Compressor and fan motor(s) thermally protected. Three-phase motors pro-
tected against primary single-phasing conditions.
2. If any of the original wire furnished must be replaced, it must be replaced with
type 90° C wire or its equivalent.
3. Jumpers are omitted when unit is equipped with EconoMi$er.
5. IFCB must trip amps are equal to or less than 140% FLA.
6. The CLO locks out the compressor to prevent short cycling on compressor over-
load and safety devices. Before replacing CLO, check these devices.
7. Number(s) indicates the line location of used contacts. A bracket over (2) num-
bers signifies a single-pole, double-throw contact. An underlined number sig-
nifies a normally closed contact. Plain (no line) number signifies a normally open
contact.
