Installation using brackets for vertical mounting
It is also possible to install the unit vertically with the engine downwards and upwards.
Two vertical mounts are used for this purpose. In the brackets there are Ø9mm holes for
M8 screws. In the EPP housing, drill holes Ø 12-13mm in front of existing holes in the
steel intake grille. The exact location is indicated by special tags on the EPP housing and
the figure below. Then insert the spacer sleeves into the holes and fix the brackets.
Screw the remaining screws into the nuts under the steel intake grille so that both grips
are in one plane. Locknuts under the handles are used to secure the screws from
unscrewing.
Connection of heating medium
The connection of the heating medium to the heat curtain, using G 1/2" threaded
connections should be made based on 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. The direction of connection to the water heater does not affect air curtain
works.
In the 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 that is located on the exchanger collector on
the engine side.
Connecting the power supply and control system of the curtain
To connect the power supply, control and/or bleed the Exchange move out the right
lid, which is fastened with the lock to the lower steel housing and the main housing
EPP. The lid is disassembled in the direction shown by the arrows in the figure below.
The lid should be grasped in the following places indicated in the drawing and should
be gradually "released" from the locks for several millimeters. Cable entries for power
and control cables are located on the inlet grille.

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
The minimum distance between device and floor cannot be less than 100 mm
Ensure that no connection wire is clamped between the lid and the rest of the curtains before assembling the lid.
