Only qualied electricians with a work permit for electrical units up to 1000 V are allowed
for installation and maintenance. The present user’s manual should be carefully read
before beginning works.
• Single-phase power mains must comply with the acting local electrical norms and standards.
• Fixed electrical wiring must be equipped with an automatic circuit breaker.
• The unit must be connected to power mains through a QF automatic circuit breaker integrated into the fixed wiring
system. The gap between the circuit breaker contacts on all poles must be not less than 3 mm. Check the unit for any
visible damages of the impeller and the casing before starting installation. The casing internals must be free of any foreign
objects that can damage the impeller blades.

noisy operation. Misuse of the unit and any unauthorised modifications are not allowed.
• Take steps to prevent ingress of smoke, carbon monoxide, and other combustion products into the room through open
chimney flues or other fire-protection devices. Sufficient air supply must be provided for proper combustion and exhaust
of gases through the chimney of fuel burning equipment to prevent back drafting. Transported air must not contain any
dust or other solid impurities, sticky substances, or fibrous materials.
• Do not use the unit in a hazardous or explosive environment containing spirits, gasoline, insecticides, etc.
• Do not close or block the intake or exhaust vents in order to ensure efficient air flow.

BRIEF DESCRIPTION
The unit described herein is an axial fan for exhaust ventilation of small to medium-sized premises heated during winter.
The fan is made of white plastic. The fan design can also include a backdraft damper to prevent back flow when the fan is
switched off. The fan fits 100 mm air ducts.
OPERATION GUIDELINES
The fan is rated for connection to single-phase AC 230 V/50 Hz or 230 V/60 Hz power mains. Air motion direction in the
system must match the pointer on the fan casing.
Ingress protection rating against access to hazardous parts and water ingress is IP45.
The fan is rated for operation at the ambient temperature ranging from +1 °C up to +45 °C.
The unit is rated as a Class II electrical appliance.

INSTALLATION AND SETUP
The fan is designed for wall or ceiling mounting with direct air exhaust to the ventilation shaft or into the round air duct of
matching diameter (Fig. 2).
Fan installation sequence:
Step 1. Cut off power supply and make sure electricity has been turned off (Fig. 4).
Step 2. Run the power cable to the vent hole (Fig. 5).
Step 3. Remove the front panel from the fan. Then remove the terminal block cover (Fig. 6).
Step 4. Mark and drill holes for mounting the fan and then install the fan (Fig. 7-9).
Step 5. Connect the fan to power mains according to the wiring diagram (Fig. 13-16).
Step 6. Install the terminal block cover (Fig. 10) and the front panel on the fan casing (Fig. 11).
Step 7. Supply power voltage to the fan (Fig. 12).

FAN SETUP
on — interval timer turning on and adjustment is performed with the potentiometer Ton. To turn the interval timer off
set the potentiometer Ton into the leftmost position. Rotation of the potentiometer for 1/3 clockwise sets the interval timer
operation for 6 hours, rotation of the potentiometer for 2/3 clockwise sets the interval timer operation for 12 hours, and
rotation of the potentiometer clockwise in the rightmost position sets the interval timer operation for 24 hours.
off — To adjust the fan turn-off delay time, turn the control knob To clockwise to increase and counter-clockwise to
decrease the turn-off delay time respectively, adjustable from 2 up to 30 minutes.
— To adjust the humidity set point turn the control knob H clockwise to increase and counter-clockwise to decrease the
humidity sensor set point, adjustable from 60 % up to 90 %.
WARNING! If the switch is turned o or the indoor humidity falls below the set point within 60 seconds after
activation of the switch or the humidity sensor, the fan continues operation at low speed.
Terminal designations on wiring diagrams:
L — phase
N — 0
S — external switch
QF — automatic circuit breaker
CAUTION! The fans rated for 12 V power voltage (stated on the packing box and on the fan casing) connect to
12 V power mains only!
DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT
OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD.

ELECTRONICS OPERATION ALGORITHM
The fan with the timerT — the fan is started after actuation of the external switch, e.g. the light switch. The control voltage
is supplied to the input terminal LT (ST). After the control voltage is off the fan continues to operate within the set time
period adjustable from 2 to 30 minutes by the timer.
The VT model is turned on and off by the pull-cord switch.
The fan with the timer T1 — after turning on the switch, for example, a light switch, the fan is switched on in a set turn-on
delay time period, adjustable from 0 to 2 minutes. After the switch is turned off the fan keeps operating for a set turn-off
delay time period, adjustable from 2 to 30 minutes.
The fan with the timer and the humidity sensor TH — the fan starts after the control voltage is supplied to the input
terminal S or if indoor humidity level Hexceeds the set point adjustable from ~60 % to ~90 %. After the control voltage is off
or the humidity level has decreased the fan will keep running within the time set by the timer ranging from 2 to 30 minutes.
To set the maximum humidity setpoint 90 % set the potentiometer to H max position.
To adjust the fan turn-on delay time, turn the control knob T clockwise to increase and counter-clockwise to decrease the
turn-on delay time respectively. To adjust the humidity set point turn the control knob Hclockwise to increase and counter-
clockwise to decrease the humidity sensor set point.
CAUTION!The timer circuit is live! Disconnect the fan from power mains prior to any adjustment operations. The
fan delivery set includes a specially designed plastic screwdriver for fan settings adjustments. Use it to change
the turn-on and turn-o delay time and the humidity set point.
DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT
OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD.
