INSTALLATION
Valid for models: Optima Wireless
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, 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).
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.
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).
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.

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
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 is an inbuilt keypad controller placed in the service door, which allows to switch
the fan speed and the power stage of the electrical element.
2 ventilation speed.
Remote control: All the standard controllers have an IR receiver that works by infrared.
Unheated air curtains controller
Common characteristics to all controllers for electrical heated air curtains
2 speed system with 2 different Fan Speed and Heating Stages (H1, H2).
Controller for electrical heated air curtains
Two heating stages: On the first heating stage a green LED turns on, and on the second stage the
LED becomes red.
Thermal Limitation: to work the heating there must be any ventilation speed selected, what allow us
to choose the maximum heating capacity with the minimum ventilation.
Time of delay: When the equipment is stopped, and it has been working, the electrical heater is still
heating during several minutes by thermal inertia with the consequent increase of internal
temperature. In order to avoid internal damages by overheating, when we stop the air curtain, it
keeps turned on for a period of time.
The air speed and the heating stage are indicated by a lighted LED while the safety function is indicated by a
flashing LED.
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.

MAINTENANCE INSTRUCTIONS
For safety, before any cleaning, disconnect power supply using the controller.
It is forbidden to open the service door (risk of electrical discharge and being
trapped in fans).
Service and maintenance should be done only by introduced and qualified
workers.
Do not use water or steam for cleaning the internal parts and components of
the air curtain.
External cleaning
Air curtains don’t need any kind of maintenance except from the cleaning of the casing and the inlet grille.
It is recommended to weekly clean the inlet grille. It’s important to make sure that the air curtain is OFF,
otherwise the dust mixed with a wet cloth would create a kind of paste that will damage the fan rotor when it
sucks the air.
Annual cleaning of the discharge area (outlet).
The casing of the air curtain should be cleaned with a wet cloth and non-aggressive detergent. Do not use
caustic soap or acids.
The inlet grille prevents the settling of dust and strange objects in the internal elements. It is recommended to
check periodically that the inlet grille is free of any object that could interfere the air entrance (plastic bags,
papers, etc.).
In case of a micro drilled inlet grille (it has filter functions to prevent the entrance of dust to the internal
elements) use a vacuum cleaner with a soft brush in order to avoid any damages in the micro drilled grille.
We recommend cleaning the grille every week (depending on the amount of the incoming air dust).
Internal cleaning
In models with micro drilled grille is recommended to clean the inside of the unit with a vacuum at least once
every two years (*), best before the winter season, with qualified staff.
(*) These periods are indicative, depending on the ambient conditions of every installation.
In places with a high number of particles in suspension is desirable to increase the frequency of the internal
cleaning (including the city centers, near construction sites, etc.).
