NOTES:

1. If any of the original wire furnished must be replaced, it must be replaced with type 90 C wire or its equivalent.
2. Compressor and fan motors are thermally protected. Three phase motors are protected against primary single phasing

conditions.

3. On 208/230V units, transformer is wired for 230V. If unit is to be run with 208V power supply, disconnect black wire from

230V tap and connect to 200V tap. 230V, 200V taps on transformer do not appear on 575V transformer and 575V tap does

not appear on 208/23/460V transformer.

4. Use copper, copper clad, aluminum or aluminum connectors.
