CC200-CC50 CONTROLLER OPERATING SEQUENCE
Cadexair's CC200-CC50 controller (see Appendix 1) is a commercial kitchen hood control panel
that uses automatic detection technology to monitor hood filter saturation. It is designed to help
maintain proper ventilation and extend the life of the filters, thereby reducing maintenance and
operating costs.
Cadexair's CC20 control box (see Appendix 2) is equipped with differential pressure sensors that
measure air resistance across the hood’s filters. The sensors send this information to the CC200-
CC50 controller, which uses an algorithm to determine the saturation level of the filters.
When the filters reach a pre-set saturation level, the CC200-CC50 controller triggers a pre-alarm
to alert kitchen staff that it is time to replace the filters.
By monitoring and regulating hood filter saturation, the Cadexair CC200-CC50 controller can
extend the life of the filters by increasing the exhaust setting to compensate for the increase in
static pressure caused by the accumulated grease in the filters.
Consult the Cadexair CC200 controller manual for the options specific to CC50 and the project.

USER INTERFACE CC50 SECTION / STADIUM SECTION (AIR CLEANER)
To access the Stadium hood page, simply use the navigation buttons from the main or secondary
page. On this page, you can see the filter status and differential pressure in real time.
The differential pressure is measured to determine filter clogging. When it reaches the pre-alarm
threshold, a notice is displayed to give users enough time to change the filters before reaching the
maximum clogging allowed. When maximum clogging is reached, the system shuts down
completely and displays another message.
If a filter(s) is removed, the system will detect it and shut down immediately.
If a variable speed or 2 speed system is used, 2 pressure settings must be
entered.
In a variable speed system, the pressure setting will be between the "Low"
and "High" settings (0%=Low, 100%=High) depending on cooking
activity.
In a 2-speed system, the setting used varies according to the speed
schedule. When the schedule is in high speed, the "High" setting is used,
and the "Low" setting is used the rest of the time.
When a single speed system is used, only the "Low" setting is used.

HIGH TEMPERATURE - FIRESTAT
There is a high temperature sensor in the air cleaner’s filter unit or in the Stadium hood. If the
temperature rises above 107oC (225oF), the contact sensor opens. The system will switch to the
Inactive mode and the cooking appliances will be shut down. A fire indication will be displayed
and the blower will shut off.
INSTALLATION
DELIVERY AND HANDLING
It is the responsibility of the purchaser to coordinate hood delivery to the job site with the proper
means of transportation, taking into account the size of the hood and access to the job site.
When using a forklift to move components over 6 feet (1.8 meters), the forklift must have long
forks.
Upon receipt of the goods, the purchaser must inspect the hood to ensure that all material is in
good condition before signing the delivery acceptance documents.
In case of damage, the buyer must clearly indicate it on the carrier's acceptance document and
notify Cadexair as soon as possible by providing photos of the damaged merchandise.
CHECKING THE PARTS – RECEIPT
Buyer should check the delivery slip to ensure that all parts on the packing slip are included in
the delivery.
If any parts are not included in the delivery, refer to the delivery slip attached to the shipment.
All claims for missing parts must be made within 72 hours of receipt of the goods. Claims made
after this period may be refused by Cadexair.
STORAGE
Do not store hoods outdoors and avoid exposure to sunlight.
Avoid storing the hood where the temperature is above 35 degrees Celsius to prevent damage
when removing the adhesive film protecting the stainless-steel.
7

SIZING AND POSITIONING THE HOOD
The size of the hood is an essential element for the proper operation of the product and for
compliance with product certification.
The hood must have a minimum overhang of 12 inches (300 mm) in front of the equipment and 6
inches (150 mm) on the sides.
Additional overhangs may be recommended during project specific product selection.
The lower front edge of the hood must be installed a minimum of 42 inches (1067 mm) from a
cooking surface such as a grill, stove, fryer or griddle.
Refer to the hood manufacturing drawings and dimensions to install the hoods in the right places
(hood direction, position of the hood in the cooking islands, etc.).
When laying the hoods on the floor, place protective material under the hood to avoid damaging
the stainless steel.
IMPORTANT
The Stadium hood is fitted with various access doors on the front of the hood. These
doors must remain accessible to replace the various filters. It is also important to
provide a clearance of 30 inches (700 mm) in front of the hood.
8

CLEARANCE TO MATERIALS
Be sure to meet the clearance standards for semi-combustible and combustible materials. A
commercial range hood must be installed 3 inches (75mm) from materials classified as semi-
combustible and 18 inches (460mm) from combustible materials. This clearance applies to both
walls and ceilings.
WEIGHT VALIDATION
Confirming the weight of each hood is an important step to ensure that the anchors and fastening
methods used are appropriate for the weight of the hood. To verify this, refer to the hood weight
table provided by the manufacturer or calculate the weight of the hood based on its dimensions
and the materials used.
Once the weight of the hood has been determined, it is important to verify that the anchors and
fastening methods used are appropriate to support the weight of the hood. Anchors must be of the
proper size and load capacity and adapted to the supporting structure such as walls or ceilings.
Fastening methods must comply with building and safety regulations.
If there is any doubt as to the ability of the anchors and fastening methods to support the weight
of the hood, it is recommended to consult a qualified professional to perform an evaluation and
recommend appropriate solutions. This may include modifications to the support structure,
additional anchors or fastening methods to ensure the safety and stability of the hood.
IMPORTANT
The Stadium Series hood is heavier than standard hoods.
LIFTING, SUSPENSION AND LEVELING
Attach the anchor points to the building structure according to the position of the hood’s
suspension brackets and install a 7/16" (11mm) threaded rod in the anchor points according to the
position of the brackets. See below for typical hood anchor position without a spacer for clearance
from combustible materials.
Adjust the length of the threaded rods to meet the hood installation height standards.
9

Lift the hood and secure the hood with the threaded rods. All suspension brackets for the hood
must be held by a threaded rod. Adjust the height of the hood with the bolts of the threaded rods
within the suspension brackets to make the hood level.
CONNECTING THE EXHAUST COLLAR TO THE HOOD
Unless the authorities having jurisdiction have approved lower quality ductwork, as permitted by
ULC-S-647, the exhaust duct must meet NFPA 96 standard.
IMPORTANT
According to NFPA 96, the duct must be at least 16-gauge steel or 18-gauge
stainless-steel. The duct must be continuously welded and watertight.
Hoods sometimes have factory-made holes. Always ensure that these are free of
obstructions and that they are accessible for the installation of future building site
components.
The exhaust outlet must be connected via a complete and continuous weld. When welding, protect
the stainless-steel surfaces from contamination.
It is possibleto connect the exhaust outlet to the hood as shownin the following figure from NFPA
96.

PLUMBING CONNECTION FOR SELF-CLEANING HOODS
The self-cleaning hood series is equipped with a 3/8" compression brass fitting for each hood
section. The hoods are equipped with a 2" female NPT drain connection.
ELECTRICAL FITTINGS
Hoods are frequently equipped with lights. Depending on the type of product, lighting is pre-wired
per hood section to a junction box. Some models require connecting each light fixture separately.
Refer to the diagram on the manufacturing drawings to ensure that the wiring is done properly.
TOP ACCESS TO HOODS
Provide access to the top of the hoods for maintenance, electrical fittings, control components,
plumbing connections and fire protection system components, even after construction is complete.
SILICONE
Once the hood is in place, it is recommended to seal the various hood sections or between the hood
and the walls with silicone.
Recommended silicone: Kason RubbaSeal aluminum color
PARASISMIC
It is the responsibility of the purchaser to follow seismic installation requirements as defined by
an engineer specializing in this type of installation.
FIRE PROTECTION SYSTEM
According to NFPA 96 standard, using this type of hood over cooking appliances requires the
installation of a fire extinguishing system for the exhaust ducts and the cooking appliances. This
system is operated by fuses or thermal sensors built into the hood. In case of fire, the air intake is
maintained and the blower is interrupted. The filter casings, ductwork and cooking surfaces are
sprayed with a chemical. Gas and electricity supply to the cooking appliances and the lighting
under the hood are cut-off and an alarm sounds.
11

INSTALLATION AND ADJUSTEMENT OF GEO-VARY FILTERS
Before starting up the hood, the filters need to be installed. Begin by inserting the top of the filters
into the slot located at the top of the hood and then placing the base of the filters in the grease
collection gutter.
Geo-Vary filters have a predetermined location and specific
adjustment. The Geo-Vary identification must always be on
the front. Make adjustments according to the instructions on
the label inside each hood (see Appendix 3).
AIRFLOW BALANCING
For hoods with baffle filters, turn on the exhaust fan and check the rotational direction before
balancing the system. Make sure that all the filters are in place and have on hand the flow rates
required to operate the hood correctly.
Cadexair recommends the following method,
based on measurements taken using a propeller
anemometer with a 2.75" (70 mm) wheel. Take 5
velocity readings in the filter slots as shown in the
image below. Measurements should be taken
perpendicular to the top of the filters at a distance
of approximately 2" (50 mm).
Calculate the average velocity per filter by adding
together the 5 mean velocity values and dividing
by 5.
Then, multiply the average velocity obtained by the effective area factor according to the filter’s
size:
SIZE EFFECTIVE AREA
H x W (IN) SQ . FT SQ . M
16 x 16 1,36 0,126
16 x 20 1,75 0,163
16 x 25 2,24 0,208
20 x 16 1,75 0,163
20 x 20 2,25 0,209
20 x 25 2,88 0,268
12

For calculations in imperial units, use air velocity units in feet per minute and use the effective
area value in square feet (SQ.FT) for a flow rate in cubic feet per minute (CFM). For calculations
in metric units, use air velocity units in meters per hour and use the effective area value in square
meters (SQ.M) for a flow rate in cubic meters per hour. To convert a flow rate from cubic meters
per hour to liters per second, multiply it by 0.278.
Before balancing the exhaust system, it is important to
check that the filters are installed and adjusted according to
the instructions on the label (see Appendix 3). It is also
recommended to start the exhaust fan and check its
rotational direction before starting airflow balancing.
Finally, it is essential to know the required flow rates to
ensure the hood operates properly.
Take 3 velocity readings in the filter slots according to the
image below. Measurements should be taken perpendicular
to the top of the filters at a distance of approximately 2"
(50mm). Calculate an average velocity per filter by adding
the 3 average velocity values and dividing by 3.
Then, multiply the mean velocity obtained by the effective area factor according to the filter’s
size.
SIZE EFFECTIVE AREA
H x W (IN) SQ . FT SQ . M
16 x 16 0,431 0,040
16 x 20 0,542 0,050
16 x 25 0,681 0,053
20 x 16 0,431 0,040
20 x 20 0,542 0,050
20 x 25 0,681 0,053

MAINTENANCE
IMPORTANT
It is strongly recommended to have replacement filters in stock at all times on the
premises where the hood is located. Despite the implementation of a normal
maintenance cycle, it is possible that particular events increase the volume of
cooking (festivals, high season, etc.)
STADIUM HOOD FILTER REPLACEMENT FREQUENCY
The pre-filters, bag filters and box filters must be changed regularly to maintain the high grease
removal efficiency required by ULC-S647 standard. When a clogged filter alarm is activated, it
means that a set of filters has reached its grease holding capacity. Further use will restrict the
exhaust airflow, causing smoke particle capture problems in the hood. Therefore, all three filters
must be changed before a clogged filter alarm is activated.
We recommend changing the filters after the pre-alarm is activated for the corresponding set of
filters.
IMPORTANT
Once the contractor has completed the installation of the STADIUM unit, change
the pre-filters immediately. The pre-filters will likely be filled with construction
debris, which will affect the initial operation of the unit.
1. Enter the start date on the attached FILTER CHANGING SCHEDULE (Appendix 4). This is
also the date the pre-filters were changed.
2. Operate the unit until the pre-alarm for clogged filters comes on. Change the filters
corresponding to the alarm at the end of the shift, or the next day before cooking. Write the date
and type of filter you changed on the FILTER CHANGING SCHEDULE under filter change
number #1/current.
3. Determine the number of days between the start date and the date the filters were changed. Add
this number of days to the last current pre-filter change and enter this new pre-filter schedule
date into the calendar under filter change number #2/schedule. Change the corresponding filters
on this new date.
14

STAINLESS-STEEL MAINTENANCE
Stainless-steel is highly resistant to corrosion, but requires regular maintenance to maintain its
surface integrity. Clean the metal as soon as it becomes soiled and avoid waiting until deep
cleaning is necessary. Regular cleaning with a mild soap or detergent, followed by a hot water
rinse, usually works well. If the water contains a lot of minerals, wipe the surface with a soft cloth
to dry it.
Use commercial products specifically designed for stainless steel, following the manufacturer's
instructions carefully. Avoid using chlorine-based cleaners or their derivatives (e.g., bleach or
Lysol).
Cleaners can be applied directly to the surface or with a soft cloth or sponge. Rinse thoroughly
with clean water and wipe with a soft dry cloth or allow to air dry. Always rub in the direction of
the grain. If necessary, specialists can be called in to polish stainless steel on the premises,
manually or electrically.
Perform the following maintenance operations according to this schedule:
Daily: wipe down the visible parts of the hoods, check the control box display, and wipe down
the Geo-Vary filters.
Weekly: clean the baffle filters, empty the residue cups under the modular degreasers.
Monthly: remove and clean filters, clean grease traps, check exhaust fan belt, check makeup
air filter systems.
IMPORTANT
Inspection and cleaning of the hood exhaust and fire protection systems is required
by law and by some insurance policies.
15

INSPECTION AND MAINTENANCE OF EXHAUST AND FIRE PROTECTION
SYSTEMS
Owners of commercial kitchens should have their exhaust systems inspected regularly to ensure
staff and public safety. Consult your insurance company to know the inspections required by local
regulations.
Fire suppression equipment requires regular maintenance to comply with local fire codes. NFPA
96 requires two annual inspections, including the replacement of the components specified in the
applicable standard.
