Some Randell Air Systems canopy hoods will be designed with our patented Air Volume
Controllers (AVC) located directly behind the standard filter bank. The AVC are specially
designed to exhaust high volumes of air over high heat - high grease producing equipment
thereby reducing the total exhaust volume.
The AVC were factory set, based on the cooking equipment specified on the approved
drawings, therefor the AVC will not have to be adjusted. AVC ‘s can be removed for hood
cleaning also. If, however, the cooking equipment has changed or should change in the
future, the following procedure should be followed.
AVC ADJUSTMENT INSTRUCTIONS
1. Remove all grease filters from the hood.
2. Loosen retaining screws on channels holding the AVC at each end.
3. Slide AVC up or down as needed. The higher the AVC is moved the greater will be
the exhaust volume.
4. Reset the retaining screw at the desired position.
5. Replace grease filters.
