Temperature control
Temperature control of FC maintains the
exhaust temperature. Should the temperature
exceed the preset value, the overheating alarm
Maintenance
Since fan motors and other components are
maintenance-free, no maintenance other than
cleaning is necessary. The level of cleaning can
vary depending on local conditions. Undertake
cleaning at least twice a year. Inlet and exhaust
grilles, impeller and elements can be vacuum
cleaned or wiped using a damp cloth. Use a
brush when vacuuming to prevent damaging
sensitive parts. Avoid the use of strong alkaline
or acidic cleaning agents.
Start-up
When the unit is used for the first time or after
a long period of non-use, smoke or an odour
may result from dust or dirt which has collected
on the element. This is completely normal and
disappears after a short time.
Adjustment of the air curtain and airflow
The direction and speed of the airflow should
be adjusted considering the load on the
opening. Pressure forces affect the airstream
and force it inwards towards the premises
(when the premises are heated and the
outdoor air is cold).
The airstream should, therefore, be directed
outwards to withstand the load. Generally
speaking, the higher the load, the greater the
angle required.
Basic setting fan speed
The fan speed when the door is open is
set using the control. Note that the airflow
direction and the fan speed may need fine
adjustment depending on the loading of the
door.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1. Disconnect the power supply.
2. The front hatch is removed by removing the
screws on the top of the unit and then detach
the bent edge at the bottom. (Fig.3)
3. After the service, repair and maintenance
reattach the front hatch. Place the hatch at
the lower edge with the bent edge and fasten
on top with screws.
Note that when carrying out work where the
end is removed, the outlet grille also detaches.
will activate. For more information see the FC
manual.
Overheating
The air curtain unit with electrical heating is
equipped with an overheat protection. If it is
deployed due to overheating, reset as follows:
1. Disconnect the power supply with the isolator
switch.
2. Determine the cause of overheating and
rectify the fault.
3. Remove the front hatch.
4. Press the red button located inside the air
curtain unit, at the inner gable of the terminal
box.
5. Reattach the front hatch and connect the unit
again.
All motors are equipped with an integral
thermal safety cut-out. This will operate,
stopping the air curtain should the motor
temperature rise too high. The cut-out
will automatically reset when the motor
temperature has returned to within the motor’s
operating limits.
Replacing the PC board
1. The PC board is located in the terminal box.
Fig. 2
2. Mark and disconnect the cables to the PC
board.
3. Remove the screws securing the board and
lift out.
4. Install the new PC board as above in reverse
order.
Replacing heating elements/heating
package (E)
1. Mark and disconnect the cables to the
heating elements/package.
2. Remove the mounting screws securing the
heating elements/package in the unit and lift
the heating elements/package out.
3. Install the new heating elements/package in
reverse order to the above.
Replacing motor or impeller
1. Remove the front.
2. Remove gable end.
3. Remove the screw between motor and fan.
4. Disconnect the cables to the motor.
5. Remove the screws securing the motor and
lift it out together with the impeller.
6. Install the new motor and/or the new
impeller as above in reverse order.
