MEASURING AND ADJUSTING THE AIR
FLOW RATES OF THE COOKER HOOD
Standard ventilation
The volume flow rate of the air inside the cooker hood is measured
with the damper closed and, where required, adjusted based on
the static pressure loss and the performance scheme of the cooker
hood .
• The static pressure loss is measured from the hole in the
damper using the measuring tube found in the accessory bag
(see Figure) .
•
Determine the volume flow rate from the performance scheme
based on the measured pressure and the number of open
holes in the damper .
Adjustment:
• Cover the required number of holes in the damper with the
magnetic strip that is delivered with the cooker hood .
