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.
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.
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 can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved.

WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT
MAINTENANCE AND REPAIR.
BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN
OBJECTS E.G. FOIL, PAPER.
• Check the electrodes and make sure there are no cuts or cracks in the insulation after unpacking the fan. Check the fan casing and
make sure it is not deformed or damaged.
• Make sure the impeller rotates smoothly and never touches the entry flange or casing. Make sure the electric circuit parameters
match the technical data specified on the fan’s label, which is on the casing, prior to connecting.
• In case the fan is used in conditions where it is exposed to water ingress, it must be protected. A possible protection option may be
installing the fan under a hood or a roof.
• Since the unit is classified as a class I electrical appliance, it requires grounding: connect the terminal box to the protective
grounding circuit.
Fan series OV…EC, OVK…EC are wall-mounted using a connecting casing and fastening holes.
DESIGN AND OPERATING PRINCIPLE
MOUNTING AND SETUP
OV…EC and OVK…EC consist of casing 1 with a square or round flange, to which a grille 2 is attached with bolts 4, assembled with the
motor and the impeller. Its rotation direction is determined by the type of the motor that is used with the external rotor. The fans have a
terminal box with a cable suitable for external connection.
The motor casing has a threaded M4 hole for connection to the protective grounding circuit.

• The unit is rated for connection to power mains with the parameters specified in the «Technical data» section according to the wiring
diagram.
• The unit must be connected to power mains using insulated electric conductors (cables, wires). The wire cross section selection
must be based on the maximum load current, maximum conductor temperature depending in the wire type, insulation, length and
installation method.
• The unit must be connected to power mains following the power connection scheme and the terminal designation.
• 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 must exceed the maximum current consumption of the unit (refer to the
«Technical data» section). 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 circuit breaker is not included in the delivery set.
• The fan is connected to the power mains and additional external devices via the terminal box.
• External speeed controllers that are connected should provide the motor input voltage of 0 to 10 V or PWM-signal with an amplitude
of 10 V.
