Page: 5 / 20

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.

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).
