SAFETY REQUIREMENTS

All user’s manual requirements as well as the provisions of all the applicable local and national construction, electrical, and technical norms and standards must be observed when installing and operating the unit.
Disconnect the unit from the power supply prior to any connection, servicing, maintenance, and repair operations.
Only qualified electricians with a work permit for electrical units up to 1000 V are allowed for installation. The present user’s manual should be carefully read before beginning works.
Check the unit for any visible damage of the impeller, the casing, and the grille before starting installation. The casing internals must be free of any foreign objects that can damage the impeller blades.
While mounting the unit, avoid compression of the casing! Deformation of the casing may result in motor jam and excessive noise.
Misuse of the unit and any unauthorised modifications are not allowed.
Do not expose the unit to adverse atmospheric agents (rain, sun, etc.). Transported air must not contain any dust or other solid impurities, sticky substances, or fibrous materials.
Do not use the unit in a hazardous or explosive environment containing spirits, gasoline, insecticides, etc.
Do not close or block the intake or extract vents in order to ensure the efficient air flow.
Do not sit on the unit and do not put objects on it.
The information in this user’s manual was correct at the time of the document’s preparation.
The Company reserves the right to modify the technical characteristics, design, or configuration of its products at any time in order to incorporate the latest technological developments.
Never touch the unit with wet or damp hands.
Never touch the unit when barefoot.

This unit is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the unit by a person responsible for their safety. Children should be supervised to ensure that they do not play with the unit. This appliance incorporates an earth connection for functional purposes.

Connection to the mains must be made through a disconnecting device, which is integrated into the fixed wiring system in accordance with the wiring rules for design of electrical units, and has a contact separation in all poles that allows for full disconnection under overvoltage category III conditions.

INSTALLATION AND SET-UP

| BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN OBJECTS (E.G. FOIL, PAPER).
---|---

The air motion in the system must be as shown with the pointer of the fan casing.
In case of the vertical installation the intake spigot must be protected with a ventilation hood.
To attain the best performance of the fan and to minimise turbulence-induced air pressure losses while mounting, connect straight air duct sections to the fan
spigots on both sides of the fan.
Minimum straight air duct length:

equal to 1 air duct diameter on intake side
equal to 3 air duct diameters on outlet side

If the air ducts are too short or not connected at any spigot, protect the fan inner parts from ingress of foreign objects by installing a protecting grille or other protecting device with mesh width not more than 12.5 mm to prevent uncontrollable access to the fans.
While installing the fan ensure convenient access for subsequent maintenance and repair. The unit must be mounted on a an even wall.

INSTALLATION STEPS

Disconnect the fan from power supply

Install the fixing brackets

Lean the fan against the installation place and mark the fastening holes

Drill the holes and insert the expansion anchors

Fix the fan

Connect air ducts

CONNECTION TO POWER MAINS

| THE UNIT MUST BE MOUNTED BY A QUALIFIED EXPERT ONLY, PROPERLY TRAINED AND HAVING THE REQUIRED TOOLS AND MATERIALS.
---|---

The unit is rated for connection to single-phase ac 230 V/ 50 (60) Hz power mains. For electric installations use insulated durable heatresistant conductors (cables, wires) with the minimum wire cross section 0.75 mm2. The conductor cross section value must be selected depending on the wire type, maximum permissible heating temperature, insulation, length and installation method.
Connect the fan to power mains via an external automatic circuit breaker installed at the power input and integrated in the house cabling to open the circuit in case of short circuit or overload.
The circuit breaker location must provide quick access for emergency shutdown of the fan.
The fan is connected to the terminal box attached to the fan casing in compliance with the wiring diagram and designation of terminals.
The terminal designation is shown on the sticker attached to the internal wall of the terminal block.

ACCESS TO THE TERMINAL BOX

Disconnect the fan from power supply

Unscrew the 4 screws that fix the terminal box lid

Route the cables through the cable gland and complete electric connection

Reinstall the terminal box lid

The fan can be equipped with a power cord with an IEC C14 connector. The fan is rated for continuous operation.

Electronics operation algorithm
The Un/U1n/U2n fan is equipped with an electronic module TSC (speed controller with an electronic thermostat) for automatic speed control (air flow) depending on the air temperature.
The terminal compartment incorporates 2 control knobs:

presetting speed
setting electric thermostat threshold value

The fan is equipped with two indicators:

temperature sensor indicator (hereinafter referred to as TSI) – yellow colour
motor control indicator (hereinafter referred to as MCI) – green/red colour

When the fan turns on, the TSI indicates the unit operation algorithm:

one pulse Un
two pulses U1n
three pulses U2n

The MCI lights up in green when the motor rotates and in red when it stops (or rotates very slowly).
To set the thermostat threshold, rotate the thermostat control knob clockwise to increase or counter-clockwise to decrease the temperature set point.
To set the fan speed (air flow), rotate the speed control knob in the same way. UN: In this case, fan speed switching operations are rare.
The TSI lights up and the fan switches to the maximum speed as the room air temperature exceeds the set point.
As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the TSI goes out and the fan operates with the set speed.
U1N: The speed switching operations are more frequent as compared to the temperature-based functioning logic ( U ), but one speed interval continues at least 5 minutes.
The TSI lights up and the fan switches to the maximum speed as the room air temperature exceeds the set point.
As the air temperature drops down below the set point, the TSI starts blinking, the timer starts a 5-minute countdown and then the fan switches to the set lower speed and the TSI goes out.
U2N: The fan starts only at a certain air temperature.
The TSI lights up and the fan switches to the set speed as the room air temperature exceeds the set point.
As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the TSI goes out and the fan turns off.

| ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY.

MAINTENANCE

| CUT OFF POWER SUPPLY BEFORE ANY OPERATIONS ARE PERFORMED.
---|---

Technical maintenance means regular cleaning of the unit surfaces of dust. Use a soft brush or compressed air to remove dust. Clean the impeller blades at least every 6 months.
Installation of an air filter prolongs the interval between the cleaning, to perform the cleaning first remove the screws and the fan cover.
Wipe the impeller blades with a cloth wetted in a mild detergent solution. Avoid water dripping on the electric motor!
After cleaning of the impeller install the cover and tighten the screws.

TECHNICAL MAINTENANCE STEPS

STORAGE AND TRANSPORTATION REGULATIONS

Store the unit in the manufacturer’s original packaging box in a dry closed ventilated premise with temperature range from +5 ° to +40 ° and relative humidity up to 70 %.
