USER MAINTENANCE AND SENSOR ADJUSTMENT
Before starting work ensure the fan is disconnected from the power
supply.
Cleaning should be done with a soft cloth wet with soap solution; after that, the
surfaces should be rubbed dry. The blades of the fan need careful cleaning
each 6 months. For this purpose, it is necessary to take the blade wheel off the
motor shaft (holding it by the boss). The blades should be cleaned with
solution of water and a detergent. Please avoid water entry on the motor.

The fan with timer options switches on when the voltage is
supplied to clamp LT. After the voltage is disconnected the fan
continues working during the time T, which is regulated from 2
till 30 minutes. The time T is regulated by turning the
potentiometer clockwise to increase and anticlockwise to
decrease the delay time (Fig. 5.1)
The fan with timer and humidity sensor
switches on when voltage is supplied to
clamp LT or when the definite humidity
level ( regulated from 60% till 90 %) is
exceeded. After the voltage is

disconnected or humidity level H is decreased, the fan continues
working during the time set by timer T, which is regulated from
2 till 30 min. The options of time T and humidity H are regulated
by turning the potentiometers T and H clockwise to increase and
anticlockwise to decrease the delay time and humidity level
respectively. To set the maximum humidity level the potentiometer H has to be
set in position H max (90%).
Attention! If during the regulation the potentiometer H is set outside of the
indicated zone rightwards from H max there is a probability that the fan will not
switch on. In this case, it is necessary to check the position of the potentiometer
(Fig. 5.2).

The fan with the timer and movement sensor switches on
when a person moves at the distance from 1 till 4 meters with
viewing angle of the sensor of 100° horizontaly. After the
person stops moving the fan continues working during the set
time T, which is regulated from 2 till 30 minutes. The time T is
regulated by turning the potentiometers clockwise to increase
and anticlockwise to decrease the delay time (Fig. 5.3)
