4. ELECTRICAL CONNECTION
Electrical connection work must be carried out by qualied personnel. Electrical connection work must be
carried out according to the NF C15-100 standard, which requires the motor to be protected by an all-pole
device with an opening distance of 3mm per contact.
Don’t forget to connect the earth electrode.
In case of use for smoke extraction, please refer to the NF S 61-932 standard for connection and installa-
tion. Use CR1-C1 high-temperature cable. The cable MUST be protected against UV radiation.
In case of use in “comfort” mode, the motor must be protected by an appropriate thermal protection device.
Attention! Before carrying out any work, check that the power supply has been shut o󰀨.
N.B.: For each speed, the direction of rotation of the wheel must match the direction shown by
the arrow found on the product. A unit with a wheel that does not turn in the right direction stills
creates air ow and reduces pressure in the duct. Incorrect direction of rotation causes abnormal
motor heating, potentially even destruction, and cancels our manufacturer’s warranty.
Wiring without INTZ
Remove the unit side panel using a 13mm spanner. Connect the power cable directly to the motor’s ter-
minal box (cable glands are supplied). Start up the motor for a few seconds to test the direction of rotation
of the turbine. If the direction of rotation is incorrect, invert 2 phases (three-phase motor). N.B. in case of
a two-speed motor, check the direction of rotation of the turbine for both speeds. Shut the motor terminal
box and replace the unit side panel.

Wiring with mounted-wired INTZ
Remove the unit side panel using a 13mm spanner. Connect the power cable to the INTZ (cable glands
are supplied) according to the nameplate included on the unit. Start up the motor for a few seconds to test
the direction of rotation of the turbine. If the direction of rotation is incorrect, invert 2 phases (three-phase
motor). N.B. in case of a two-speed motor, check the direction of rotation of the turbine for both speeds.
Close the INTZ box and replace the unit side panel.

7/8 NT00000602-KSHA-KSHR-AN-200605
Wiring with PILOTAIR®
Connect the power cable in the PILOTAIR®according to the manual included with the relay cabinet (cable
glands supplied) Start up the motor for a few seconds to test the direction of rotation of the turbine. If the di-
rection of rotation is incorrect, invert 2 phases on the PILOTAIR®power supply terminal block (three-phase
motor). N.B.: in case of a Comfort-Smoke Extraction PILOTAIR®, please refer to the PILOTAIR®manual.
Pressure switch wiring
If the pressure switch is factory-installed, it is fastened to the inside of the unit on the motor side. Open the
unit side panel then the cowl located on the pressure switch. Connect the 2 connection cable wires. Set
the pressure switch trigger value. Close the pressure switch cowl then the unit side panel.
Variable speed pulley adjustment (optional)
Shut o󰀨 the power supply before carrying out any work and make sure that it cannot be accidentally turned
back on.
• Unscrew the four locking screws on the side of the motor bracket
• Loosen the belt by unscrewing the tightening screw provided for this purpose
• Depending on the type of variable-speed pulley:
Unscrew the 4 hexagon-socket locking screws, ad-
just the mobile ange and screw the 4 screws back
in.
Unscrew the 2 hexagon-socket locking screws, ad-
just the mobile ange and screw the 2 screws back
in, making sure that they press against the bottom
of the 2 grooves, to avoid damaging the pulley’s
thread.
To reduce the rotation speed: unscrew the mobile ange screw
To increase the rotation speed: screw in the mobile ange screw
Attention! The fan’s rotation speed must never exceed the maximum speed of rotation specied
on the product nameplate.
5. COMMISSIONING
Before starting up the turbine, make sure that the fan, motor and transmission set rotates freely and that
no objects are liable to be launched by the turbine. The unit must be connected to the aeraulic network
and the side panels closed.
Briey turn on the power supply to check the turbine’s direction of rotation.
For each speed, the wheel’s direction of rotation must match the direction shown by the arrow
found on the product. If the wheel’s direction of rotation is incorrect, the motor is damaged and our
manufacturer’s warranty is cancelled.
All installation and maintenance work must be carried out with the wheel stopped and the device discon-
nected. During operation, check that the motor’s input current does not exceed the current specied on
the plate by more than 5%.

8/8 NT00000602-KSHA-KSHR-AN-200605
Once installation and testing are completed, present the main points of the user and maintenance manual
to the user. Depending on the control system set to be installed on the unit, it will be necessary to explain:
• How to turn the machine on and o󰀨.
• How to modify the operating modes.
Provide the user with the unit’s instruction manual and the user and maintenance manuals of the accesso-
ries installed (control, variable frequency drive, etc.) so they can be consulted at any time.
6. MAINTENANCE
Maintenance frequency depends on operating conditions. If the air has a high impurity content, the time
between two checks must be reduced. In general, the fan must be inspected at least twice a year.
Attention! Shut o󰀨 the power supply before carrying out any work and make sure that it cannot be turned
back on during the work (lockout-tagout).
Fan: annual maintenance
Remove the dust on the fan blades. For the kitchen version, an inspection panel provides access to the
turbine.
Transmission: half-yearly maintenance
When using new belts, their tension must be checked and adjusted after 30 minutes of operation, if nec-
essary.
• Check the belt’s state of wear.
• Check the belt’s tension as follows:
-Apply force F as shown in the diagram, below, to achieve flex of f (mm) = 16xA (m)
-The force F to be applied varies according to the diameter of the smallest pulley and the type of belts
