Notes:
1. Remove jumper to install field optional low ambient switch.
2. Step-down transformer assembly for 460/575 volt units.
3. Selective voltage terminal for proper unit voltage
4. Optional low ambient switch.
5. Optional motorized intake damper.
6. Unit may be wired for HI, MED, or LO speeds. Diagram shows the HI speed setup, to rewire for MED or LO speed, disconnect 

BK-101 from relays and connect BL-101 for MED, or RD-101 for LO. Also connect WH-101 to BK-101.

7. Optional stop, start and jog control.
8. Matching adapter harness (provided) to connect with rooftop unit. For energy management systems c24v to green 

and common 24v to black.
