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 electricity supply with the fully
isolated switch.
2. Allow the electrical coil to cool.
3. Determine the cause of overheating and rectify
the fault.
4. Reconnect the air curtain.
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.

Temperature control

Temperature control of SIRe maintains the
exhaust temperature. If the temperature
should exceed the preset value anyway
the overheating alarm goes off. For more
information see the manual for SIRe.

Fan replacement

1. Determine which of the fans is not functioning.
2. Disconnect the cables from the relevant fan.
3. Remove the screws securing the fan and lift
the fan out.
4. Install the new fan as above in reverse order.
Replacing heating elements (E)
1. Mark and disconnect the cables to the electric
coil package.
2. Remove the mounting screws securing the

Troubleshooting
If the fans are not working or do not blow properly,
check the following:
• That the intake grille/filter is not dirty.
• Functions and settings of the SIRe control
system, see manual for SIRe.
If there is no heat, check the following:
• Functions and settings of the SIRe control
system, see manual for SIRe.
For units with electrical heating, also check the fol-
lowing:
• Power supply to electric heater coil; check
fuses and circuit-breaker (if any).
• That the overheat protection has not been
deployed.
For units with a water coil, also check the following:
• That the water coil is air free.
• That there is sufficient water flow and
pressure.
• That incoming water is heated adequately.
If the fault cannot be rectified, please contact a
qualified service technician.
Residual current circuit breaker (E)
When the installation is protected by means of
a residual current circuit breaker, which trips
when the appliance is connected, this may be
due to moisture in the heating element. When
an appliance containing a heater element has
not been used for a long period or stored in
a damp environment, moisture can enter the
element.
This should not be seen as a fault, but is
simply rectified by connecting the appliance to
the main supply via a socket without a safety
cut-out so that the moisture can be eliminated
from the element. The drying time can vary
from a few hours to a few days. As a preventive
measure, the unit should occasionally be run
for a short time when it is not being used for
extended periods of time.
