DESIGN AND OPERATING PRINCIPLE

The unit is housed in a sound-insulated galvanized steel casing (item 1). The unit casing has 4 mounting brackets with anti-vibration
connectors for ceiling or wall mounting (item 5).
The air flow direction is indicated by the arrow on the fan casing.
The bottom side of the casing is covered by a removable cover (item 2), which is secured with 4 bolts (item 4).
A control unit (item 3) is installed on the casing. The power and control cables are pulled through cable glands (item 6). The unit is
equipped with a water heater.
On side surfaces of the units there are openings for connecting heat medium supply (item 8.1) and return (item 8.2) pipes.
To facilitate unit's connection to the heat medium supply and return pipelines, the water heat exchanger can be moved to connect
either on the right or left side of the casing, regardless of the location of the control unit.

For ease of electrical connection, the units can be ordered with the control unit located either on right or left side of the casing (right- and
left-side versions, respectively, as indicated in the "Designation key" section).
If necessary, the control unit can be moved to the other side of the unit casing before being installed in the ventilation system.
