ZEN model
Installation work, connection, disconnection, electrical wiring, mechanical
maintenance and service must be done by quali ed people observing these
instructions and in accordance with all applicable norms and standards.
If the unit is operated with additional controller, please consider its speci c
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 xations
are external. They are placed on top or lateral 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.
H MAX� Maximum recommended range, MIN� Recommended minimum distance
(*) Standard equipment� Upon request, this distance can be reduced to 25 mm when the connections
are located inside the equipment and the tube outlet is lateral� In this case, dimension B will be 100 mm�
The minimum recommended distance between the suction grille and any obstacle is 200 mm (Dimension A)
Dimension D: service opening distance�

To connect the device to power, there is a black junction box at the interior of 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)�

Each installation must be reviewed by an specialist to ensure that there is no incompatibility with the selected
dierential and the connected curtains.

Fixings
The curtain has four external fastening points
depending on the weight and length (see si-
tuation in the model characteristics section)�
Generally, air curtains are installed ho-
rizontally� For vertical installation, use
the feet kit (see accessories 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)�
Regulator and board
To connect the controller to the curtain, there is a connector located in the inside of the air curtain�
Use the 7 meter RJ45 cable supplied with the equipment� The communication between the controller and the
board is digital and low voltage�

Instruction manual - Air curtain ZEN 9
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 (outow 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)�
Electrical 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 three 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
instructions”)�
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 heating power (kW) Regulation type
9 / 12 / 15 / 18 / 22,5 / 24 PRBEO
30 CONTACTORS
The water batteries have a drain screw in the collector area�

Storage temperature between -20 ⁰C and +40 ⁰C.
When transporting the material, you must ensure that it is not damaged by the forklift�
(possible penetration of the fork in the packaging)� Observe the instructions on the packaging for correct
manipulation of the product�
Warning! Heavy load.
Do not stand under the suspended load during transportation or assembly.
For safety, the air curtains must never be stopped by disconnecting the
current, always do it through the controller. If the power is turned o to
turn o the shade, or within ten minutes of turning it o with the controller,
internal components may be damaged.
There are various regulator models depending on the customer’s needs: timers, antifreeze detectors,
thermostats, etc�
- 5 fan speeds�
- Memory: guarantees that, in the event of a power outage, the selected speed is maintained when
service is restored� This function can be activated/deactivated using the ON/OFF switch located inside the
regulator�
Common characteristics to all regulators
Characteristics of regulation boards
Depending on the type of fan, the air speed is regulated by:
- AC (MG): 110 - 230 V voltage range�
- EC (ECG): from 0 - 10V DC voltage range�
