Operation and Maintenance Documentation
It is important to note that the minimum distance between the unit and the floor for installation with engine at the bottom is not less than
100mm. This allows access to the electrical terminal strip and to the water exchanger vent.
The connection of the heating medium to the heat curtain, using G 1/2” threaded connections, should be made on the basis of a design
by an authorized designer. If the air curtain is connected to a district heating network without a mixing unit, a water filter is required.
In case of horizontal and vertical mounting with nozzles at the top, the exchanger is vented through the nozzles. If the device is mount-
ed vertically with nozzles at the bottom, to vent the exchanger, use a vent which is located on the exchanger collector on the engine
side.
ATTENTION !
It is necessary to ensure that the unit is properly leveled. When it
is mounted in a position other than vertical or horizontal there is
a risk of fan damage and unit malfunction
