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 qualied 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

THE PRODUCT MUST BE DISPOSED SEPARATELY AT THE END OF ITS SERVICE LIFE.

DO NOT DISPOSE THE UNIT AS UNSORTED DOMESTIC WASTE.

If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or

similarly qualiﬁed persons in order to avoid a safety hazard.

CAUTION: In order to avoid a safety hazard due to inadvertent resetting of the thermal cut-

out, this unit must not be supplied through an external switching device, such as a timer, or

connected to a circuit that is regularly switched on and oﬀ by the utility.

Ensure that the unit is switched oﬀ from the supply mains before removing the guard.

WARNING: If there are any unusual oscillating movements, immediately stop using the unit and

contact the manufacturer, its service agent or suitably qualiﬁed persons.

The replacement of parts of the safety suspension system device shall be performed by the

manufacturer, its service agent or suitably qualiﬁed persons.

Precautions must be taken to avoid the back-ﬂow of gases into the room from the open ﬂue of

gas or other fuel-burning appliances.

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

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

min 1D min 3D

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.

BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN

OBJECTS E.G. FOIL, PAPER.

www.ventilation-system.com

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

VKM EC

www.ventilation-system.com

CONNECTION TO POWER MAINS

The unit is rated for connection to single-phase ac 230 V/ 50 (60) Hz power mains. For electric installations use insulated durable heat-

resistant 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.

THE UNIT MUST BE MOUNTED BY A QUALIFIED EXPERT ONLY, PROPERLY TRAINED

AND HAVING THE REQUIRED TOOLS AND MATERIALS.

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.
