H MAX� Maximum recommended range, MIN� Recommended minimum distance
(*) Standard equipment� Upon request, this distance can be reduced to 10 mm when the connections are
located inside the unit and the tube outlet is at the rear� In this case, dimension B will be 10 mm�
The minimum recommended distance between the suction grille and any obstacle is 200 mm (Dimension A)
Dimension D: service opening distance�
Installation work, connection, disconnection, electrical wiring, mechanical
maintenance and service must be done by qualied people observing these
instructions and in accordance with all applicable norms and standards.
If the unit is operated with additional controller, please consider its specic
instructions.
There is no need to open the service panel to connect the air curtain. All
connections (power supply, control, water pipes when existing) and xations
are external. They are placed on top or lateral of the units. See how to open
service panel 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.

Fixings
To connect the device to power, there is a black junction box inside the air curtain�
For curtains without heating or with water heating, the curtain must only be connected to a 230V single-phase
current for the operation of the fans�
In the case of a curtain with an electric battery, connect the 400Vx3 three-phase power supply from the
electric battery� Optionally, the battery power can be 230Vx3 three-phase or 230Vx1 single-phase (special
diagram included)�
Thesingle-phase currentisonly connectedto onephase ofthethree-phase lines,plus aconnection totheneutral�
Recommended maximum number of curtains connected to the same dierential:
Each installation must be reviewed by a specialist to ensure that there is no incompatibility with the selected
dierential and the connected curtains.
The curtain has several external fastening points
depending on the weight and length (see situa-
tion in the model characteristics section)�
Generally, air curtains are installed horizontally�
For vertical installation, use the feet kit (see ac-
cessories section)�
The anchor must be sized according to the
weights of each curtain indicated on the techni-
cal data page� The installation can be done using
threaded rods, tensioners or other supports (see
available supports in the accessories section)�
Board and regulator
To connect the controller to the curtain, there is a connector located on the inside of the air curtain� It is ne-
cessary to open the curtain to connect it, except for internal connections�
Use the 7 meter RJ45 cable supplied with the equipment� The communication between the controller and the
board is digital and low voltage�

Water coils
The air curtains with water coil have a 230Vx1 output to optionally connect a solenoid valve (it opens or clo-
ses the water inlet to the heat exchanger of the coil)� This outlet can also be used for other low amperage
electrical appliances (10A)�
Recomendations:
• Close the hot water circulation (valve) to avoid overheating of the motors while the equipment is o. Op-
tionally, we have solenoid valves�
• In the installation of the building, two shut-o valves (outlet and return) should be provided to be able to
disassemble the equipment without problems�
• Mount a purge valve at the highest point of the heating section�
The ambient temperature must always be higher than +4º C� Otherwise, the equipment must be provided
with a frost protection device (antifreeze sensor)�
The water coils have a drain screw in the collector area�
Electric coils
The electric battery has nine resistances in the form of a bar that, combined with each other, provide 3 stages
of heating� Control is carried out by 3 PRBEOs up to 27kW included� From there, the control is carried out
by two contactors�
All the batteries are electrically and electronically protected against overheating (see section “operating ins-
tructions”)�
Electric controllers have the option of including an external thermostat to control heating on and o based on
temperature�
During the rst uses, the electric battery can give o some odor that disappears in a few days.
According to battery power, the regulation is carried out by:
Coil power (kW) Regulation type
9 / 12 / 15 / 18 / 22,5 / 24 PRBEO
