HOOD TROUBLESHOOTING
Initial troubleshooting of the hood:
1. Make sure that the RUN lamp and POWER lamp on the VFD are lit.
2. Check to see that the green fan LED on the switch plate is on.
3. Check the actual frequency of the VFD controller. To access the actual frequency, press and
hold the <FUNC> button until the Display Mode shows D001. Release the button, and then
press one (1) more time. This will show actual operating parameters, not programmed parame-
ters.
4. Check to see that the breaker on the hood electrical box is not tripped.
5. Check to see that the breaker in the service panel is not tripped.
6. Make sure the Switch Relocation Cords (SRC) are properly installed to the oven(s).
7. Check to see that the grease filters are clean & installed properly.
8. Check to see if the exhaust fan is rotating in the correct rotation. To verify fan rotation, re-
move the lid on the exhaust fan. Visually inspect rotation in accordance with label on fan hous-
ing.
