Electrical installation
The air curtain(s) must only be connected by
a competent electrician, and in accordance
with the applicable regulations.
Electrical installation can be carried out
from the top/bottom for vertical mounting and
from the left/right for horizontal mounting.
For AD Corinte A the wiring can be run
internally through the unit to the terminal
block. Secure the wiring inside the unit with
cable ties to prevent it being sucked into the
fans.
For AD Corinte E the wiring should be run
directly to the connection box. The radiation
protection plate need to be removed to enter
the connection box, see Fig. 9. The protection
plate protects the connection box from
radiant heating from the elements and must
be put back after the installation.
The motors are wired as standard for a
three phase 230 V supply, but they can be
reconfigured for a three-phase 400 V supply,
see page 10. Frequency inverter ADCF15N or
similar should be used for speed control. Each
frequency inverter can be fused using a 10A
fuse. The group should not be connected to a
safety cut-out. See wiring diagrams pages 10-
12. When another make of frequency inverter
is used, the max. frequency should be 43 Hz
and the min. frequency 16 Hz.
Use only braided, twinned copper cable
with 85% coverage, for example type RKFK,
for supply of the motors from the frequency
inverter. Foil screen has a higher capacitance
than the copper braid and is therefore not
suitable for use. See CE-EMC installation
guidelines for the frequency inverter.
Suitable cable area is 1.5 mm². Max. cable
length 50 m. For longer cable please contact
Frico.
Note! Before securing the front panel, check
that the fans rotate in the direction indicated
by the arrows on the fans, (see Fig. 6). If
not, swap two phases in the motor supply to
change the direction of rotation.
When installing ADEA please note that
the parameter FANC should be set to 1, see
instruction for ADEA for more information.
Adjustment of air flow
The direction and speed of the air flow
should be adjusted considering the load on
the opening. Pressure forces affect the air
stream and make it bend inwards into the
premises (when the premises are heated and
the outdoor air is cold). The air stream should
therefore be directed outwards to withstand
the load. (Generally speaking, the higher the
load, the greater the angle is needed.)
Use a hexagon key to loosen the three
screws supporting the outlet grille. Angle the
grille outwards so that the air flow obstructs
the incoming cold air.
Overheating
The air curtain unit is equipped with an
overheat protector, which deploys when the
temperature is too high. Reset as follows, see
figure 4:
1 Disconnect the power supply.
2 Loosen the two screws of the air intake
grille with a hexagon key and remove the
grille.
3 Determine what caused the overheating.
4 Locate the red buttons (2 x) positioned on
the overheat protection, which are mounted
on the long side of the electrical coil.
5 Press the red button until a click is heard.
6 Reinstall the air intake grille and switch on
the power.
The motors of all air curtain units are
equipped with integrated thermo contacts
to protect against overheating, where the
cables are routed to connection blocks TK-
TK. See wiring diagrams pages 10-13. The
cut-out will automatically reset when the
motor temperature has returned to within the
motor’s operating limits.
Trouble shooting
If the fans are stationary, check the following:
1 The operating power supply to the unit;
check fuses, circuit-breaker, time switch/
thermostat (if any) that starts and stops the
unit.
2 That the air flow selector is correctly set.
3 That the position limit switch is working (if
installed).
