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.
Connection of heating medium
The connection of the heating medium to the heat curtain

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 mounted vertically with nozzles at the
bottom
to vent the exchanger, use a vent which is located on the exchanger collector on
the engine side.
