Measuring Dynaflow MB Supply
Dynaflow type hood with Tri-Zone control System
Each of the three regions must be
measured to ensure proper hood
operation. The Appliance Region, the
Chef Region and the Kitchen Ambient
Region as shown in the schematic
Figure 27
The Appliance region is measured
first.
A. Measuring the Appliance Region
The Appliance Region and Chef Region discharge is called a
MJGrill. The MJGrill is manufactured as a single component shown
on the left in Figure 28. The MJGrill includes the Appliance Region
discharge, Chef Region discharge, and a adjustable Comfort Tuning
Dial. The Comfort Tuning Dial proportions the amount of fresh air
to the Chef Region.
The Comfort Tuning Dial on the MJ Grill has two colored dots; red
and blue. The Comfort Tuning Dial
proportions the volume of air to the chef.
Turning the Comfort Tuning Dial towards the
red dot provides less air to the Chef Region
and turning the Comfort Tuning Dial
towards the blue dot provides more air to
the Chef Region.
To measure the Appliance Region air velocity rotate the Comfort Tuning Dial
towards the red dot, counterclockwise to shut off air to the Chef Region. Now
measure the velocity from the MJGrill perforated discharge towards the inside of
the hood in the Appliance Region. The measurement can be made with a Hot
Wire Anemometer or Vane Axial Velometer. The required air velocity is
indicated below in Chart No. 4. If the velocity is too high or low the MB Blade
must be adjusted to increase or decrease the velocity to the Appliance Region.
