FloAire Canopy Hood - Manual (Page 36)

Adjustments
1. A hood with multiple risers should be balanced according to the cooking load beneath it. For
example, if a hood with multiple risers has a charbroiler in the center and several ovens on the
ends, the risers should be evenly balanced. This will achieve the most efficient contaminant
capture.
2. Perforated supply plenums discharging air around the hood should be set to the designed
discharge velocity.
3. When fan pulleys are adjusted, belts should then be re-checked for correct tension and an
amperage reading should be taken on the motor to make certain it is not overloaded.
4. The prime objective of balancing is to ensure that each hood will capture all the contaminants
produced by the equipment it covers without causing undesirable conditions in the kitchen (i.e.
excessive negative pressure, excessive quantities of hot or cold air in the kitchen, etc.)
If problems occur, then refer to the Troubleshooting Section of this manual.
Conclusion
1. Compare specified data to the data recorded. Adjust exhaust as necessary using adjustable
pulley on fan. Adjust supply as necessary using dampers on supply risers and adjustable pulley
on supply fan.
2. After setting hoods to specified data, the room parameters should be checked.
3. If room parameters are not acceptable yet, the hood can be modified to improve them without
decreasing hood performance. This is an acceptable condition.
4. Use a smoke bomb to verify that the hood captures adequately. This can be your final verification.
