WARNING
!
Follow the user's manual requirements to ensure durable
and trouble-free operation of the fan.
Disconnect the fan from power supply prior to any connection,
servicing and repair operations.
Only duly qualified electricians with valid electrical permit for electric
operations at the units with operating voltage up to 1000 V are
allowed for mounting and maintenance after careful study of the
present user's manual.
The single-phase power mains must comply with the acting local
electrical norms and standards.
The fixed electrical wiring must be equipped with an automatic circuit
breaker.
The fan must be connected to power mains through an automatic
circuit breaker QF integrated into the fixed wiring system with the gap
between the breaker contacts on all poles not less than 3 mm.
Check the fan for any visible damages of the impeller and the casing
before starting installation. The casing internals must be free of any
foreign objects which can damage the impeller blades.
Due to constant improvements the design of some models may slightly
differ from those ones described in this manual.

While mounting the fan avoid the casing compression!
Deformation of the casing may result in the motor jam and excessive
noise.
Misuse of the fan 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.

This fan model includes a back valve that prevents air back drafting when the fan is off.
Fan options:
6
V: the fan is turned on and off with a pull cord switch.
T: after the external switch is turned off, the fan keeps operating for a set turn-off delay time, adjustable
from 2 to 30 minutes.
T1: after the external switch is turned on, the fan turns on in a set turn-on delay time period, adjustable
from 0 to 2 minutes. After the external switch is turned off, the fan keeps operating for a set turn-off delay time
period, adjustable from 2 to 30 minutes.
TH : the fan is turned on as the indoor humidity exceeds set level, adjustable from 60 % up to 90 %.
As the indoor humidity level drops down below the set point, the fan keeps operating for a set turn-off delay
time period, adjustable from 2 to 30 minutes.
The fan may be manually turned on with a light switch.
After the switch is turned off the fan keeps operating for a set turn-off delay time period, adjustable
from 2 to 30 minutes.
TP: (applicable for Quiet-S only) the fan is turned on in case of activation of the motion sensor with the reach
distance 14 m and viewing angle up to 100°. After no motion more is detected the fan keeps operating for a set
