into the fixed wiring system in accordance with the rules for design of electrical units, and has a
contact separation in all poles that allows for full disconnection under overvoltage category III
conditions.
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 appliance 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 appliance
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.
Fixing means for attachment to the ceiling such as hooks or other devices shall be fixed with a

PURPOSE
The unit is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafes, conference halls, and other utility
and public spaces as well as to recover the heat energy contained in the air extracted from the premises to warm up the filtered stream
of intake air.
The unit is not intended for organizing ventilation in swimming pools, saunas, greenhouses, summer gardens, and other spaces with
high humidity.
Due to the ability to save heating energy by means of energy recovery, the unit is an important element of energy-efficient premises.
The unit is a component part and is not designed for stand-alone operation. It is rated for continuous operation.
Transported air must not contain any flammable or explosive mixtures, evaporation of chemicals, sticky substances, fibrous materials,
coarse dust, soot and oil particles or environments favourable for the formation of hazardous substances (toxic substances, dust,
pathogenic germs).
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.
