Notes:

1 – To operate in 208V mode replace the blue transformer wire connected to PB-L2 with red transformer wire.

2 – Jumper wires tie stages (1) with (2) and (3) with (4).

3 – Dip switches are used to select the air flow.

4 – For single circuit operation field supplied jumper wires should be applied between L1 & L3 and L2 & L4. Jumper wires must be sized to carry the single circuit ampacity of the equipment.
