Complete the wiring as shown in Motor Starter Wiring.
Unwired Collectors
1. Remove the exhaust pack. Remove all bolts and lift starting at one corner.
The gasket material is fragile and must be handled with care. If the gasket is disrupted, reposition evenly
around the inner and outer flanges when replacing the exhaust panel.
2. Make the wiring connections to the fan motor according to the wiring diagram located inside the control box and the
instructions on the motor decal.
All electrical components must be sized for the supply voltage and motor horsepower. See Motor Starter
Wiring.
3. Reinstall exhaust pack.
4. Turn the fan-motor ON then OFF and check for proper rotation by viewing through the opening on top of the collector.
To reverse rotation, single-phase power supply:
Follow manufacturer’s instructions on the motor’s nameplate.
To reverse rotation, three-phase power supply:
Switch any two leads on the motor junction box.
Check that the exhaust plenum is free of tools or
debris before checking fan rotation.
Stand clear of exhaust to avoid personal injury.
Do not interchange a power lead with the ground
wire. Severe personal injury and/or property
damage may result.
