MOUNTING AND SETUP
READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT.
BEFORE INSTALLING ADDITIONAL EXTERNAL DEVICES,
READ THE RELEVANT USER MANUALS
The unit is intended for mounting with round air ducts. The fan is installed between the air ducts. The fan casing is equipped with fixing
brackets for the suspended mounting. While installing the unit ensure convenient access for subsequent maintenance and repair.
Make sure the unit is fastened securely prior to operation. Connect the air ducts of the appropriate diameter to the fan (connections must
be airtight). Air motion in the system must be in compliance with the direction of the arrow on the fan label.
To attain the best performance of the fan and to minimise turbulence-induced air pressure losses, it is recommended to connect the
straight air duct section to the spigots on both sides of the unit while mounting.
Minimum recommended straight air duct section length is equal to 3 fan diameters (see the "Technical data" section).
If the air ducts are shorter than 1 m or not connected, the internal parts of the unit must be protected from ingress of foreign objects.
To prevent uncontrollable access to the fans, the spigots may be covered with a protecting grille or other protecting device with mesh
width not more than 12.5 mm.
BEFORE MOUNTING, MAKE SURE THERE ARE NO VISIBLE DEFECTS ON THE UNIT, SUCH
AS MECHANICAL DAMAGES, MISSING PARTS, IMPELLER JAMMING ETC
WHEN MOUNTING THE UNIT IT IS NECESSARY TO PROVIDE PROTECTION AGAINST
CONTACT WITH HAZARDOUS ZONES OF THE FAN BY INSTALLING AIR DUCTS OF THE
NECESSARY LENGTHS AND PROTECTIVE GRILLES
MOUNTING MUST BE PERFORMED BY QUALIFIED SPECIALISTS ONLY, PROPERLY
TRAINED AND QUALIFIED TO INSTALL AND MAINTAIN VENTILATION EQUIPMENT

ELECTRONICS OPERATION ALGORITHM
The EC motor is controlled by sending of an external control signal from 0 to 10 V to the X2 terminal block or by the R1 internal speed
controller. Control method selection is carried out by means of the SW DIP switch:
• DIP switch in IN position. The control signal is set by the R1 internal speed controller that enables switching the fan on/off and
smooth speed (air flow) regulation from minimum to maximum value. Rotations are controlled from the minimum (extreme right
position) to the maximum (extreme left position). When rotating counter-clockwise, the rotations increase.
• DIP switch in EXT position. The control signal is set by the R2 external control unit.
The Boost-I...T fan activates upon control voltage application to the LT input terminal by the external switch (e.g. indoor light switch).
After the control voltage is off, the fan continues to operate within the set time period adjustable from 2 to 30 min by the timer.
To adjust the fan turn-on delay time, turn the control knob T counter-clockwise to decrease and clockwise to increase the turn-on delay
time respectively.
The Boost-I...U/Un fan is equipped with an electronic module TSC (speed controller with an electronic thermostat) for automatic speed
control (air flow) depending on the air temperature. The fan switches to the maximum speed as the room air temperature exceeds the
set point. As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the fan operates with
the set speed.
The Boost-I...P fan is equipped with a speed controller that enables switching the fan on/off and smooth speed (air flow) regulation
from minimum to maximum value.

CONNECTION TO POWER MAINS
POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.
THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
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 unit is designed for connection to power mains with the parameters specified in the "Technical data" section. The connection must
be made using durable, insulated and heat-resistant conductors (cables, wires). The actual wire cross section selection must be based on
the maximum load current, maximum conductor temperature depending on the wire type, insulation, length and installation method.
The fan connection shall be made on the terminal block mounted inside the terminal box in strict accordance with the wiring diagram
and terminal designations. The external power input must be equipped with a QF automatic circuit breaker built into the stationary
wiring to open the circuit in the event of overload or short-circuit. The position of the external circuit breaker must ensure free access
for quick unit power-off. The trip current of the automatic circuit breaker must exceed the maximum current consumption of the unit
(refer to the “Technical data” section or to the unit label). It is recommended to select the nominal current of the circuit breaker from the
standard series, following the maximum current of the connected unit. The circuit breaker is not included in the delivery set and can be
ordered separately.

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE
OPERATIONS!
MAKE SURE THE UNIT IS DISCONNECTED FROM POWER MAINS BEFORE REMOVING THE
PROTECTION
TECHNICAL MAINTENANCE
Clean the product surfaces regularly (once in 6 months) from dust and dirt.
Disconnect the fan from power mains prior to any maintenance operations.
Disconnect the air ducts from the fan.
Clean the fans with a soft brush, cloth, vacuum cleaner or compressed air.
Do not use water, aggressive solvents, or sharp objects as they may damage the impeller.
It is forbidden to remove or change the location of the balancers on the impeller, as this can lead to increased level of vibration, noise
and reduce the service life of the unit.
During technical maintenance, make sure that there are no visible defects on the unit, the mounting brackets are securely fastened to
the fan casing and the unit is securely mounted.
