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;

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.
Ensure impeller rotates freely. Do not overtight on
Attention:
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 fuelburning 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.

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

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
T stops moving the fan continues working during the set time T, which is regulated from 2 till 30 minutes. The time T is
