INSTALLATION & OPERATING INSTRUCTIONS
Aura-eco
100mm & 150mm Axial Fans

Introduction
This Service Instructions are combined with technical specification, operating
guide and specification for the “Aura-eco ” fan; it contains information on
installation, that are important for ensuring correct and safe operation of the fan.
Designation
Fans are designed for ventilation of domestic and similar premises
(apartments,offices,stores,garages,kitchens, bathrooms, toilets and other
rooms, heated in wintertime).
Fans are exhaust fans and are designed for wall or ceiling mounting (Fig.6,7).
They are designed for a long-duration operation, without disconnection from
the power network.
The fan design is being constantly improved therefore some models may
slightly vary from those described in the present specification.
Set of supply
The following article is included:
- Fan 1pc;
- User's manual;
- Screws 4 pcs.
- Packing box

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.

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)
