STRUCTURE AND OPERATING LOGIC

The unit operating principle is as follows (fig. 3).
Warm stale air from the premises extracted by the unit is purified in the extract filter, then it passes
through the heat exchanger and then is exhausted outside through the ducts by the exhaust fan.
Clean cold intake air supplied to the unit is purified in the supply filter.
The air passes through the heat exchanger and then fed into the premises by the supply fan.
Thermal energy of warm extract air is transferred to clean intake fresh air from outside and warms
it up. The air flows are fully separated.
Heat recovery minimizes thermal energy losses, energy demand and operating costs for heating
during winter time.
The unit is equipped with an electric heater to enable supply air warming up to +30 °C.
Before connecting the unit to power mains make sure that the unit is free of any visible damages or
any other foreign objects inside the casing that can damage the impeller blades.
All the wireworks with the unit are allowed by a professional electrician, duly authorized for electric
operations.
Warning!
Disconnect the unit from power supply prior to any mounting, servicing, connection
or repair operations with the unit.
