SAFETY REQUIREMENTS

The fan “Aura-eco” complies with the requirements according to the EU

norms and directives.

Level of protection from access to hazardous parts and waterproof is to

IPX4

Connection of fans supplied with the electric cords to power supply as well as

replacement of electric cord should be perfomed by a competent person

(Part P) and in accordance with latest IEE wiring regulations. A 3 amp fused

isolator should be fitted.

Fan operation beyond the operational temperature range as well as in rooms

with ambient air containing aggresive mixture is prohibited.

Precautions must be taken to avoid the black -flow of gases into the room

from the open flue of gas or other fuel-burning appliances.

Attention: Ensure impeller rotates freely. Do not overtight on

ductwork connections to fan spigot.

Precautions must be taken to avoid the black -flow gases

into the room from the open flue of gas or other fuel-

burning appliances.

PREPARATION OF DEVICE OPERATION

Attention: All work must be carried out with the equipment fully

isolated from the power supply. The electrical connection

is to be carried out in accordance with the relevant wiring

diagram and are only to be done by a certified electrician.

The electrical connection must be fully isolated from the

supply up to the final assembly!

All relevant safety regulation, national standards and norms are to be adhered

to. An appliance is required for cut off from the supply with a minimum of 3mm

contact opening of each pole.

The rated voltage and frequency must correspond with the data on the type

plate. The insertion of mains supply cable is carried out via a cable grommet

which is included in the delivery. Never lead cable over sharp edges. The

equipment corresponds to protection IPX4.

USERMAINTENANCE ANDSENSORADJUSTMENT

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.

Fig. 5.1

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).

Fig. 5.3

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)
