NOTES:

1.Compressor and/or fan motor(s) thermally protected three-phase motors protected against primary single phasing conditions.

2.If any of the original wire furnished must be replaced, it must be replaced with Type 90° C or its equivalent.

3.Jumpers are omitted when unit is equipped with economizer.

4.IFCB must trip amps is equal to or less than 140% FLA.

5.On TRAN1 use BLK lead for 460-v power supply and ORN lead for 575-v power supply.

6.The CLO locks out the compressor to prevent short cycling on compressor overload and safety devices; before replacing CLO check these devices.

7.Number(s) indicates the line location of used contacts. A bracket over (2) numbers signifies a single pole, double throw contact. An underlined number signifies a normally closed contact. Plain (no line) number signifies a normally open contact.

8.620 Ohm, 1 watt, 5% resistor should be removed only when using differential enthalpy or dry bulb.

9.If a separate field-supplied 24-v transformer is used for the IAQ sensor power supply, it cannot have the secondary of the transformer grounded.

10.OAT sensor is shipped inside unit and must be relocated in the field for proper operation.

11.For field-installed remote minimum position POT, remove black wire jumper between P and P1 and set control minimum position POT to the minimum position.
