PURPOSE
The VENTS VKM/VKMz/VC centrifugal fans in a metal casing are designed for ventilation of domestic, public
and manufacturing premises heated during winter.
The transported air temperature must be within the limits stated in the "Technical data" section.
The fan is designed for horizontal or vertical mounting in an air duct and is used both for supply and
exhaust ventilation.
The unit is rated for continuous operation.
THE UNIT MAY NOT BE OPERATED BY CHILDREN OR PERSONS WITH
REDUCED PHYSICAL, MENTAL OR SENSORY CAPACITIES, OR LACKING THE
APPROPRIATE TRAINING.
THE UNIT MUST BE INSTALLED AND CONNECTED ONLY BY PROPERLY
QUALIFIED PERSONNEL AFTER THE APPROPRIATE BRIEFING.
THE CHOICE OF UNIT INSTALLATION LOCATION MUST PREVENT
UNAUTHORIZED ACCESS BY UNATTENDED CHILDREN.
Transported air must not contain any ammable or explosive mixtures, evaporation of chemicals, sticky
substances, brous materials, coarse dust, soot and oil particles or environments favourable for the formation
of hazardous substances (toxic substances, dust, pathogenic germs).

DESIGN AND OPERATING LOGIC
The VKM/VKMz fan (Fig. 4-5) consists of the casing 1, the electric motor attached to the inner xing
bracket 4, the cover 2 that is xed to the casing with screws 3 (the casing spigot diameter and the cover
diameter are equal to the connected air duct diameter), the terminal box 5 that incorporates a terminal block
and a capacitor and enables connection of the fan to single-phase power mains.
The fan models with a temperature and speed controller (Fig. 5) are equipped with a speed control knob
9, a thermostat control knob 10, a fan on/o LED light indicator 11 and a thermostat LED light indicator 12
that are located on the terminal box cover.
The fan models with the speed controller (Fig. 5) are equipped with a speed control knob 9 which is
located on the terminal box 5 cover.
The fan models with a speed controller or with a speed and temperature controller are connected to
power mains through a power cable with a plug.

MOUNTING
THE UNIT MUST BE MOUNTED BY A QUALIFIED EXPERT ONLY,
PROPERLY TRAINED AND HAVING THE REQUIRED TOOLS AND
MATERIALS.
VKM/VKMz fan
The fans are designed for vertical or horizontal mounting.
Air motion in the system must be in compliance with the direction of the arrow on the fan casing.
Install a hood on the intake spigot side in case of the vertical fan installation.
Provide a straight air duct section at least 1 m long on the intake spigot side in case of horizontal fan
installation with maximum allowable humidity.
Mounting sequence:
remove the bolt from the casing 1 and install the xing brackets in such a way so that the holes on the
xing brackets are aligned with the heads of the screws 3.
Fix the xing brackets on the casing with bolts.
Drill the holes in the mounting surface to match the tment holes of the xing brackets.
Fix the fan with the screws.
Connect the air ducts of the respective size to the fan and x them with clamps.

CONNECTION TO POWER MAINS
DISCONNECT THE UNIT FROM POWER SUPPLY PRIOR TO ANY
OPERATIONS WITH THE UNIT.
CONNECTION OF THE UNIT TO POWER MAINS IS ALLOWED BY A
QUALIFIED ELECTRICIAN WITH A WORK PERMIT FOR THE ELECTRIC
UNITS UP TO 1000 V AFTER CAREFUL READING OF THE PRESENT
USER'S MANUAL.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN
ON THE MANUFACTURER'S LABEL. ANY TAMPERING WITH THE
INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE
WARRANTY.
The fan is designed for 230 V/50 Hz single-phase alternating current mains.
The fan shall be connected to power supply by means of insulated, durable and thermal-resistant cords
(cables, wires) through the external circuit breaker with a thermal-magnetic trip built into the stationary wiring
to disconnect all the power mains phases. The rated current must be not below the rated current consumption
(refer to Technical data). The QF external switch location must ensure free access for quick shutdown of the fan.
The recommended rated current of the circuit breaker:
2 A for the VKMS 315, VKM 355Q, VCS 315 fans
3.15 A for the VKM 400, VKM 450 fans
1 A for all other fans
The recommended wire cross section is 0.75 mm2.
The actual conductor cross-section selection must be based on its type, the maximum permissible heating,
insulation, length and installation method (in the air, pipes or inside walls).
Connect the cables to the terminal block incorporated inside the terminal box located on the fan casing in
compliance with the fan wiring diagram and the terminal designation.
The terminal designations are shown on the sticker inside the fan casing.
The wiring diagram for the VKM 400, VKM 450 fans is shown in Fig. 10. The wiring diagram for the other fans
is shown in Fig. 11.
The fans with a speed controller and temperature and speed controller (VKM Un, VKMz Un, VKM P, VKMz P)
are designed for connection to single-phase AC power mains 230 V/50 Hz and are equipped with a power cord
and a plug (supplied connected to the terminal block).

The TW1, TW2 terminals are the electrical leads of the normally closed contact of the motor overheating
protection. Connect the contact in series to power circuit of the magnetic starter coil KM1 that starts the motor
after pressing the S1 button. In case of pressing the S2 button or motor overheating the contact gets broken
and switches the starter coil o to cut power o and stop the motor. The QF circuit breaker, the magnetic
starter KM1, the control knobs S1 and S2 are not included in the delivery and must be installed by the user.
The motor connection example with thermal protecting contacts leaded outside are shown in Fig. 12.

CONTROL
The VKM P, VKMz P fans with a built-in electronic module
The electronic module is designed for smooth control of fan speed (air ow). The speed is controlled with
the speed control knob 9 (Fig. 5).
The VKM Un, VKMz Un fans with a temperature and speed controller
The controller is designed for air temperature control and fan speed control depending on ambient air
temperature.
The speed is controlled with the speed control knob 9 and the temperature control knob 10 (Fig. 5).
The VKM Un, VKMz Un fans are equipped with an external temperature sensor xed on a 4 m cable.
The cover of the terminal box incorporates the following controls:
speed control knob 9 (Fig. 5)
temperature controller 10 (Fig. 5) to set the thermostat temperature threshold
on/o LED light indicator 11 (Fig. 5)
thermostat LED light indicator 12 (Fig. 5)
Operation algorithm of the VKM Un and VKMz Un fans
Set the thermostat temperature threshold with a thermostat control knob 10. Turn on the fan, then set the
fan speed with the speed control knob 9. The fan on/o light indicator 11 lights up. The controller switches the
fan to the maximum speed (maximum air ow) as the temperature rises and crosses the thermostat setpoint.
The thermostat light indicator 12 glows if the temperature is above the thermostat setpoint. If the temperature
falls 2 °C below the thermostat setpoint, the fan reverts to the preset lower speed. This prevents frequent speed
changeovers during operation with the temperature close to the threshold value. This control logic enables
tracking temperature uctuations and respond to the temperature change with accuracy up to 2 °C. The rate
of the speed switching depends exclusively on the air temperature uctuations.
