INSTALLATION
The fan can be installed vertically or horizontally in a round duct (Fig. 2) of appropriate diameter (Fig. 1).
Fan installation sequence:
• Disconnect power supply (Fig. 3).
• Mark and drill holes for fastening the mounting bracket of the fan and then install the fan (Fig. 4-6).
• Remove the terminal compartment cover and the cable clamp from the fan (Fig. 7).
• Connect the fan to power mains, screw the cable clamp into place, adjust the timer time if necessary (Fig. 8-9).
• Install the terminal compartment cover on the fan casing (Fig. 9).
• Connect the air ducts of the corresponding diameter on both sides of the fan (Fig. 10).
• Apply power to the fan (Fig. 11).
Installation, connection, adjustment and maintenance of fans without a bracket is carried out similarly, with the exception of
paragraph 2 when you just need to insert the fan into the round duct.
The fan mounting sequence is shown in Fig. 3-11.
The fan wiring diagrams are shown in Fig. 12.
Terminal designations on the wiring diagrams:
L— line/~12 V S— external switch
N— neutral/~12 V QF— double-pole circuit breaker
LT— timer control line
WARNING! 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!
WARNING! The power cable may only be laid through the hole in the casing provided by the manufacturer (Fig. 13).
Laying the power cable through a manually drilled hole will not be the liability of the manufacturer and will void
the warranty. The wires must be stripped of insulation by a maximum of 8 mm.
After installation, pass this User’s manual to the end user for reading.

from 2 to 30 minutes.
— 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.
