MAX. Maximum recommended height, MIN Minimum recommended distance
(*) Standard units. Under request this distance can be reduced to 1cm when connections are placed inside
and water pipes lateral.
Minimum recommended distance between the inlet grille and any obstacle is of 225mm.
Power Supply
To connect the power supply there is a black connection box in each fan of the air curtain (on the back).
Connection should be done directly in any black connection box at the ends of the air curtain.
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 current of the electric battery can be three phases 230Vx3 or single
phase 230Vx1 depending on model (special wiring diagram will be enclosed).
PCBoard and control (Optional in case the air curtain has regulation incorporated)
To connect the controller there is a PCBoard (printed circuit) located outside the air curtain (on the back).
There is no need to open the unit to connect it.
Use the telephone cable of 10 meters (RJ45 connectors) supplied with the equipment. The communication
between the connector plate and the controller is digital through low-voltage.
Installation work, connection, disconnection, electrical wiring, mechanical maintenance and
service must be done by qualified persons 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 from the main supply,
always through the controller and wait for 10 minutes at least to disconnect the main supply.
In case we do not follow these instructions, the internal parts of the air curtain can be
damaged.
Optionally, there are available different accessories and controllers, to meet every customer’s needs (week
timer, thermostats, door contacts, anti-freezing sensor, supports, valves, etc…).
Fixing
Units are provided with several external suspension points, depending on the weight and length (see exact
situation of the points at the air curtains characteristics page).
Generally air curtains work horizontally but also can be installed vertically using feet (accessories section).
The anchor should be managed according to the weights of each unit shown on the technical data page. The
installation can be made through threaded rods, 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. This output can also be used for other low amperage electric device (air
curtain option with regulation incorporated)
It is recommended:
• Close the warm water circulation (by closing the electro valve) to avoid motor overheating while the
unit is OFF. The electro valve is optional.
• Install 2 shut-off water valves (supply and return) in order to dismantle the equipment easily.
• Install a bleeding point at the highest part of the heating water 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 draining point placed at the end part of the intake manifold.
TRANSPORT AND STORAGE
Attention! Heavy load.
Do not step under hanging load during the transport or assembly.
Store in a dry place and weather protected in its original packaging. In case the packing is open, 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.
