The airow adjustment of a RRKZ depends on the initial pres-
sure airow running point and the type of fan.
This damper allows a higher airow adjustment with a KDTA
forward curved fan, whose airow varies more with pressure
than a KDTR backward curved fan.

4. ELECTRICAL CONNECTION
4.1 Preliminary precautions
Electrical connections must be made by qualied personnel. Do not forget the earthing connection.
In addition, the cables routing must be protected from mechanical aggressions when the connection is
made to the motor's terminal box or to the unit's safety switch. The cable must be protected from UV ra-
diation.
If used for comfort application, the electric motor must be protected by a suitable magnetothermal protec-
tion device.
The direction of rotation of the wheel must correspond for each speed to the direction indicated
by the arrow located on the product. Any unit whose wheel does not turn in the right direction will
create a ow and negative pressure in the duct. An incorrect direction of rotation causes the motor
to overheat which may render it unsuitable for use; this invalidates our manufacturer's warranty.

12/16 NT00000439-KDTA-F400-KDTR-F400-AN-210121
4.2 Wiring without any safety switch
Disassemble the lateral panel of the unit using a 13 mm wrench. Connect the supply lead directly to the
motor's terminal block (cable glands are provided).

Perform a start-up test lasting a few seconds in order to check the direction of rotation of the fan. If the
direction of rotation is incorrect, invert 2 phases (three-phase motors).
Nb. in the case of two-speed motors, check the direction of rotation of the fan for the two speeds.

4.3 Wiring with a mounted and connected safety switch
Disassemble the lateral panel of the unit using a 13 mm wrench. Connect the supply lead to the safety
switch (cable glands are provided) according to the label a󰀩xed to the unit. Perform a start-up test lasting
a few seconds in order to check the direction of rotation of the fan. If the direction of rotation is incorrect,
invert 2 phases (three-phase motors). Nb. in the case of two-speed motors, check the direction of rotation
of the fan for the two speeds. Close the safety switch's enclosure and re-assemble the lateral panel of the
unit.
4.4 Wiring with control panel (used in France)
Connect the supply lead to the control panel according to the instructions that come with this device (cable
glands are provided). Perform a start-up test lasting a few seconds in order to check the direction of rota-
tion of the fan. If incorrect, invert 2 phases on the supply terminal block of the control panel (three-phase
motor).
If a comfort-smoke extract control panel is used, see the instructions that come with this device.
4.5 Electrical connection of pressure switch
If the pressure switch is factory assembled, it is tted to the inside of the unit on the motor side. Open the
lateral panel of the unit and then the hood located on the pressure switch. Connect the 2 connection cable
threads.Adjust the triggering value of the pressure switch. Close the hood of the pressure switch and then
the lateral panel of the unit.
5. START-UP
In order to start up the fan, make sure that the whole unit, including fan, motor and transmission, rotates
freely and that there is no object that may be projected by the fan. The unit must be connected to the air
ow network and the lateral panels must be closed. The machine must be attached to its stand before
being power is applied.
Switch on just an instant to check the direction of rotation of the turbine.
WARNING: The impeller rotating direction must correspond to each speed in the direction indi-
cated by the arrow on the product. A centrifugal backward fan unit with an impeller that does not
rotate in the right direction still creates a lowrate and a low pressure in the duct. An incorrect ro-
tating direction can lead to an abnormal overheating of the motor, resulting in its destruction and
cancelling our manufacturer’s warranty.
If the rotating direction is incorrect, cut o󰀨 the electrical power supply, make sure no power is pre-
sent, and then reverse the two power supply phases at the level of the motor’s terminal box for the
three-phase motors, or make sure that the mains network connection conforms to the schematic
diagram of § "4. ELECTRICAL CONNECTION", page 11 for the single-phase motors.
While running, make sure that the motor’s absorbed current is not more than 5% above the name plate
indicated current.
Once the installation and tests have ended, present the main points of the operating and maintenance
manual to the user; the following should be explained:
• How to start up and shut down the device.
• How to change the operating modes.
Then hand over to the user with the technical instructions for use of the casing and assembled accessories
(control panel, etc.) so that they can be accessed at all times.

6. MAINTENANCE
6.1 Upkeep
The frequency of the maintenance depends on operating conditions and must comply with regulationsIf
the air is heavily contaminated with dust, the duration between two visits must be shortened. Generally,
the fan must be inspected at least twice a year.
FREQUENCY OF MAINTENANCE
Component At commissioning Each 6 month minimum
Fan Check the rotating direction; make sure that the moving and xed parts do not
rub together
Clean, if necessary ; make sure that
the moving and xed parts do not rub
together
Motor Check the connections, in particular the
ground connection Retighten the lugs, if necessary ; check the nominal current
Safety switch Check the connections, in particular the
ground connection Retighten the lugs, if necessary
Pressure switch Check the electrical/aeraulic
connections Check the operation
Control box Make sure that there are no defects ; check the connections, in particular, the
ground connection Make sure that there are no defects ;
retighten the lugs, if necessary
Protection guards Make sure that they are present Clean, if necessary
Duct network Make sure that there are no leaks Clean, if necessary
Fixing Check the mechanical tightness Retighten the screws, if necessary
When you use new belts, their tension must be checked and adjusted after 30 minutes of operation, if
necessary.
Check the wear and tension of the belt followed by the belt tension as follows:
• Apply a force F as indicated in the diagram below in order to obtain an arrow f (mm) = 16xA (m).
• The force F that is applied is variable according to the diameter of the smallest pulley and the type
of belt.

6.2 Variable pulley adjustment
Variable pulley adjustment (optional)
Cut o󰀨 the power supply before any work is performed and make sure that it cannot be re-established
accidentally.
• Loosen the four clamping screws on the side of the motor bracket.
• Untighten the belt by loosening the adjusting screw provided.
• According to the kind of variable pulley:
Loosen the 4 clamping screws, with hexagonal
socket head, adjust the mobile ange and tighten
the 4 screws again.
Loosen the 2 clamping screws, with hexagonal
socket head, adjust the mobile ange and tighten
the 2 screws again, while making sure that they
press against the bottom of the 2 grooves, so that
the threading of the pulley is not damaged.
To reduce the rotation speed: loosen the mobile ange To increase the rotation speed: tighten the mobile
ange.
WARNING: The rotation speed of the fan must never exceed the maximum rotation speed indicated
on the product identication label.
