MAX. Maximum recommended height, MIN. Minimum recommended distance
(**) Removable covers
Minimum recommended distance between the inlet grille and any obstacle is of 200mm.
Installation work, connection, disconnection, electrical wiring, mechanical maintenance
and service must be done by qualified people observing these instructions and in
accordance with all applicable norms and standards.
If the unit is operated with additional controller, please consider its specific instructions.
There is no need to open the service door to connect the air curtain. All connections
(power supply, control, water pipes when existing) and fixations are external. They are
placed on top of the units. See how to open service door at repairs section.
For safety, the air curtains never have to be stopped by disconnecting them from the
main supply, always through the controller and waiting 10 minutes at least to disconnect
the main supply. In case to not follow these instructions, the internal parts of the air
curtain can be damaged.
To connect the power supply there is a black connection box outside the air curtain (located on top).
For an ambient air, just connect the single phase 230Vx1.
In case of an air curtain with electrical heating we will also connect the three phase 400Vx3 of the electrical
element. Optionally under request the power supply of the electrical element can be single phase 230Vx1
depending on each model (special wiring diagram will be enclosed).
Units are provided of several external suspension points, depending on the weight and length of each model
(see exact situation of the points at the air curtains characteristics page).
The fixing of the air curtain should be managed according to the weights of each unit shown on the technical
data page. The installation can be made through threaded rods, cable tensors or other supports.
See available supports in the accessories section.
The heater element has 3 or 6 resistances bars (depending on the model) that combined give 2 power
stages. The control is managed by 2 PRBEO of 2 and 1 bars (in case of 3 resistances), or 4 and 2 bars (in
case of 6 resistances).
