10. Measuring and Adjusting Airflow
NORDcanopy canopies are fitted with measuring nozzles located inside the canopy.
In order to adjust supply airflow, the position of the adjusting plate located in the supply chamber is adjusted.
The exhaust airflow adjustment plate is located behind the HFM Labyrinth filters. Lock the adjustment plate in
place using the butterfly nuts!
K-factor for measuring airflow
• Exhaust K-factor = 20,6 per filter
Supply air K-factor, per 1 m of front panel
SP×0 SP×1 SP×2 SP×3 SP×K
Front panel* - 19,2 32,3 50,4 -
AirGrip 2,4 - - - -
Side panel* - - - - 6,6
* The supply panel k-factors above include the “AirGrip” air capture system K-factor.
* If the side panel has perforation, add the side panel k-value to the front panel k-value.
Calculation example:
Supply air canopy L=2 meter with SP×2 front panel.
Calculation of the supply air volume:
Pressure in the supply air chamber is 26 Pa
Front panel SP×2 k-factor is 32,3
Qs = 2 × 32,3 x √26 = 330 l/s
Calculation of the exhaust air volume:
Pressure in the exhaust air chamber is 22 Pa
4 × HFM labyrinth filter k-factor is 82,4
Qe= 4 × 20,6 x √22 = 386 l/s
ATTN! During measurement, all HFM Labyrinth filters and exhaust chamber access hatches
must be in place and the front panel must be closed.

11.1 Installation of Cover Plates
12. Kitchen Canopy Maintenance
DEPENDING
ON THE
FREQUENCY OF
KITCHEN USAGE
All internal and external surfaces of the kitchen canopy, including light fixtures, are
cleaned using neutral cleaning agents. Carefully rinse the surfaces after cleaning, in
order to avoid harmful interactions of cleaning agents and high temperatures. To clean
the exhaust chamber, HFM filters and the COVER SUPPORT RAIL (pictured below)
are removed from the kitchen canopy. To clean the supply chamber, the front panel
of the kitchen canopy is removed. ATTN! Do not use hard or abrasive detergents,
chlorine or bleach when cleaning the canopy! Never clean the kitchen canopy when
any of its surfaces are hot.
Occasionally check the water nozzles. These need to be cleaned if water spray pattern
is changed (see below).
To clean HFM Labyrinth filters they must be removed from the kitchen canopy. Liquid
grease must always be disposed of using methods approved according to local
regulations.

12.4 Removing Water Nozzles
Water spray should be parrallel to the rear wall. Turn nozzles so that they are all in line.
When servicing nozzles, make sure they are installed in the right direction.
