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.

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.

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.

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

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.

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

DO NOT DISPOSE THE UNIT AS UNSORTED DOMESTIC WASTE.

The fan is connected to the ventilation duct by means of a counter ﬂange, which is attached

directly to the fan base (see «Mounting and set-up»).

www.ventilation-system.com

THE UNIT SHOULD NOT BE OPERATED BY CHILDREN OR PERSONS WITH REDUCED

PHYSICAL, MENTAL, OR SENSORY CAPACITIES, OR THOSE WITHOUT THE APPROPRIATE

TRAINING.

THE UNIT MUST BE INSTALLED AND CONNECTED ONLY BY PROPERLY QUALIFIED

PERSONNEL AFTER THE APPROPRIATE BRIEFING.

Depending on the model the fan casing is made of polymer coated steel, aluminium or galvanized steel.The units feature electronically

commutated (EC) direct current motors with an external rotor and centrifugal impellers with backward curved blades. EC motor is

free of friction and wear parts such as a commutator and brushes. These components are replaced by a maintenance-free electronic

circuit board.

DESIGN AND OPERATING PRINCIPLE

• Fans are designed for horizontal mounting on a ﬂat roof directly above an air duct or a ventilation shaft.

• In order to avoid ingress of water and snow into the ventilation duct, it is possible to install a fan on the mounting frame.

• The fan is connected to the ventilation duct by means of a counter ﬂange, which is attached directly to the fan base.

• The fan base has holes for ﬁxing bolts that attach the fan to a stationary even surface or to a mounting frame.

• In the VKV 225 EC, VKV/VKH 500 EC, VKV/VKH 630 EC models the counter ﬂange is attached together with the fan inlet ring.

• A mounting frame, a counter ﬂange and mounting bolts are not included in the delivery set and must be purchased separately.

CONNECTION TO POWER MAINS

DISCONNECT THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.

CONNECTION OF THE UNIT TO POWER MAINS IS ALLOWED BY A QUALIFIED

ELECTRICIAN WITH A WORK PERMIT FOR THE ELECTRIC UNITS UP TO 1000 V AFTER

CAREFUL READING OF THE PRESENT USER’S MANUAL.

THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE

MANUFACTURER’S LABEL.

• The unit is rated for connection to power mains with the parameters speciﬁed in the «Technical speciﬁcations» section, according to

the wiring diagram.

• The unit must be connected to power mains using insulated electric conductors (cables, wires). The actual wire cross section selection

must be based on the maximum load current, maximum conductor temperature depending on the wire type, insulation, length and

installation method.

• The external power input must be equipped with an automatic circuit breaker built into the stationary wiring to open the electric

circuit in case of overload or short-circuit. The circuit breaker installation place must provide quick access for emergency shutdown

of the unit. The trip current of the automatic circuit breaker QF must exceed the maximum current consumption of the unit (refer

to the technical data table). The recommended trip current of the circuit breaker is the next current in the standard trip current row

following the maximum current of the connected unit. The automatic circuit breaker is not included in the delivery set.

• The technical maintenance includes periodic cleaning of the surfaces from accumulated dust and dirt.

• When carrying out fan maintenance, it is necessary to partially disassemble it in order to access contaminated parts of the fan.

• The impeller blades require thorough cleaning once in 6 months.

• Use a soft dry cloth, brush or compressed air to remove dust.

• Carry out wet cleaning using warm water and a mild household detergent.

• Protect the electric motor against liquid ingress.

• Do not immerse the unit in water!

• Do not use aggressive solvents, or sharp objects as they may damage the impeller.
