INSTALLATION
Valid for models: Optima
MAX. Maximum recommended height, MIN. Minimum recommended distance
(**) Removable covers
Minimum recommended distance between the inlet grille and any obstacle is of 200mm.
Power Supply
To connect the power supply there is a black connection box outside the air curtain (located on top).
For an ambient air or water heated air curtain, 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 water coil or electrical element can be three phase
230Vx3 or single phase 230Vx1 depending on each model (special wiring diagram will be enclosed).
PCBoard and Control
To connect the controller there is a PCBoard (printed circuit) located outside the air curtain (located on top).
There is no need to open the unit to connect it.
Use the 7 meters RJ45 cable supplied with the equipment. The communication between the controller and
the PCB is digital and low-voltage.
Optionally, there are different accessories and controllers available, to meet every customer needs (Clever
Control, thermostats, hand-auto, door contacts, anti-freezing sensor, supports, valves, etc.).
The new total control for ventilation technology is advanced Clever regulation. Leading the new generation of
air curtains management with maximum control providing maximum energy saving. Clever automatically
adapts the functioning of the air curtain to the entrance climatic conditions in order to keep the comfort and
energy saving.
For more information ask for Clever Control manual.
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 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.

Fixing
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.
Water coils
Water heated air curtains have a PCBoard with an output of 230Vx1 to install an electro valve
(open/close water entrance) or any other device.
It is recommended:
•Close the hot water circulation (by turning the electrovalve OFF) to avoid fan overheating while the
unit is OFF. Electrovalve is optional.
•Install 2 cutoff water valves (supply and return) in order to disassemble the equipment easily.
•Install a bleeding valve at the highest part of the water heating circuit.
The ambient temperature should be always over +4ºC, otherwise it will be necessary to provide an anti-frost
protection device.
Water coils have a drainage point placed at the end part of the intake manifolds area.
Electrical elements
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).
All electrical elements are protected electrically and electronically against overheating (see “Operating
instructions” section).
The electrical controllers have the option to install an external thermostat that turns on/off the heating in order
to control the temperature.
During the first uses scent can be emitted but it disappears in a few days.
STORAGE AND TRANSPORT
Attention! Heavy load.
Do not step underneath hanging load during the transport or assembly.
Store in a dry place and weather protected in its original packaging. In case the packing is opened, cover the
air curtain to protect it from dust. Do not step or put heavy load over the package to avoid damages to the
material. Store temperatures are between -20ºC and +40ºC.
When carrying material, make sure it is not damaged by the forklift (fork penetration in the packaging).
Please see the Packaging instructions.

WORKING INSTRUCTIONS
For safety, the air curtains never have to be stopped by disconnecting them from the
main supply, always through the controller and wait for 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.
Control PCBoard characteristics
The PCBoard relays adjust the 2 ventilation and heating speed in case of electrical heated air curtains.
Controller’s common characteristics
•Controllers: There are several models depending on the customer’s needs (timers, anti-freezing
detectors, thermostats, etc.).
•2 ventilation speed.
•Memory:When a power shortage happens, it guarantees that the selected speed
will be maintained when the service is re-established. This function can be
connected or disconnected through the switch ON/OFF placed inside the
controller.
•RJ45 cable and digital communication:“Plug and Play” easy and fast
connection through RJ45 cable and digital communication between the controller
and the air curtain. This kind of communication is more reliable even at long distances.
•External ON/OFF: Inside the controller we can connect a normally open contact (1, 2) that controls
the ON/OFF of the equipment through any external device, the contact is potential-free. When the
contact is Open, the air curtain is ON. When the contact is closed the air curtain is OFF. It has a 30
seconds delay. It can be used with programmable timer, temperature sensors, fire alarms, PLC, etc.
•Remote control: All the standard controllers have an IR receiver that works by infrared.
Common characteristics to all controllers for water heated air curtains
Unheated air curtain controller
Warm water heated air curtain controller
Water heated air curtain auxiliary function:
•Heating ON/OFF: It is possible to activate/deactivate the current of 230Vx1 to the electrovalve to
open/close the water entrance to the coil. This 230Vx1 output connector is placed on top of the
equipment, besides the telephone cable connection of the controller.
•How to control an electro-valve with an external thermostat: To control the inlet water to the
battery through a thermostat, we must install it in series with the electro-valve. Thus, when it reaches
the selected temperature, the electro-valve will close.
•Safety thermostat: If the internal temperature increases to 60ºC and the first speed being selected, it
automatically turns to the second ventilation speed. It will continue to the maximum speed till the
internal temperature is lower than 50ºC. The emergency operating is indicated by a flashing LED.
If the safety activates too often the cause must be determined. The most probable is that we have to
increase the cleaning of the inlet grill with more regular recurrence.
For example, an obstruction in the inlet grill, the inactive motor or a too high ambient temperature in an
installation with no ambient thermostat or a water temperature of the water coil over 80ºC would
increase automatically the speed fan.
It also avoids that the expelled air by the air curtain is over 60ºC (too high temperature sensation for
people).

Common characteristics to all controllers for electrical heated air curtains
2 speed system with 2 different Fan Speed and Heating Stages (H1, H2).
•Limited heating: for safety reasons, in references OPT/RO 1000 of 9kW the heating power is limited
by the ventilation speed that we had selected, the following way:
Selected speed Max. heating power that can be selected
V1 Stage 1 heating
V2 Stage 2 heating
To apply this limitation, the default control work
jumper JP1 must be retired.
In the rest of the references, any ventilation speed
can be selected with any heating power.
Furthermore, for safety reasons of the equipment, the
heating power does not work if no speed fan is
operating. It can be selected any speed with any
heating power.
Warning: If the air ambient temperature is high, and
we select the maximum heating and the minimum
speed, the electronic safety ventilation will repetitively
activate.
•Thermostat of relay: When the equipment is stopped, and the heating has been working, there is an
increase in temperature (by thermal inertia) inside the equipment that could damage it. In order to
avoid internal damages by overheating, when we stop the curtain and the internal temperature is over
50ºC, there is a delay thermostat having the function to turn on again the fans automatically with
maximum speed till the temperature goes under 50ºC. This safety operating is indicated with a flashing
green LED.
•Safety thermostat: When the air curtain operates with heating and the internal temperature increases
over 50ºC, a safety function activates: The air curtain increases one speed every two minutes till it
reaches the maximum speed. After, it will start decreasing 1 heating stage till it stops. In case that
after 2 minutes the situation persists, the heating will block. To unblock it, we must manually reset by
disconnecting from the main supply. If in any moment the temperature decreases (below the set
temperature) this process is interrupted and everything goes back to the normal situation.
A delay in the cleaning of the inlet grille or a high ambient temperature could temporally activate this
function.
The air speed and the heating stage are indicated by a continuous lighted led, while the safety function
is indicated by a flashing LED. The blockage of the heating is indicated with the led OFF of the heating
flashing at a higher speed.
Controllers auxiliary function:
•Ambient Thermostat: The air curtain is equipped with contacts to install, if desired, an ambient
thermostat in order to stops the heating temporally when reaching the programmed temperature. This
installation is specially recommended for equipments installed in closed or small dimensions premises.
In case of installing an ambient thermostat remove the bonding jumper between terminal 4 and 5, on
the controller.
Special controllers
If there is a will to control more parameters, there are two controllers that allow a lot more possibilities in
comparison with the standard control, especially Clever. The following controllers have specific user manuals:
•Hand Auto
•Clever Control
