BRIEF DESCRIPTION
The unit described herein is an axial fan for exhaust ventilation of small to medium-sized premises. 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 is
designed for connection to ø 100 , 120, 125 and 150 mm air ducts.
OPERATION GUIDELINES
The fan is rated for connection to single-phase AC 220-240 V/50 Hz, 220-240 V/60 Hz or 12 V/50 Hz power mains depending
on the fan model (see information on the fan).
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 IP34.
The fan is rated for operation at the ambient temperature ranging from +1 °C up to +40 °C.
The unit is rated as a Class II electrical appliance (220-240 V) or as a Class III electrical appliance (12 V).

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. 3).
Step 2. Run the power cable to the vent hole (Fig. 4).
Step 3. Remove the fixing screw and the front panel of the fan (Fig. 5).
Step 4. Remove the terminal block cover (Fig. 6).
Step 5. Mark and drill holes for mounting the fan (Fig. 7-8).
Step 6. Install the fan and connect to power mains (Fig. 9) according to the wiring diagram (Fig. 12-15).
Step 7. Install the terminal block cover (Fig. 9) and the front panel on the fan casing (Fig. 10).
Step 8. Supply power voltage to the fan (Fig. 11).

ELECTRONICS OPERATION ALGORITHM
The fan with the timer T — 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 LT (by using a pull cord switch for VTH models) or if indoor humidity level Hexceeds the set point adjustable from ~60
% to ~90 %.
After the control voltage is off (by using a pull cord switch for VTH models) 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 Hmax position.
To adjust the fan turn-on delay time, turn the control knob Tclockwise 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.
DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT
OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD.
