Overheating
The air curtain unit with electric heater is
equipped with an overheat protector. The
overheat protection is reset by turning
off the switch and the unit cools. If it is
deployed due to overheating, reset as follows:
1. Disconnect the electricity with the fully
isolated switch.
2. Allow the electrical coil to cool.
3. Determine the cause of overheating and
rectify the fault.
4. Connect the air curtain 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.
Temperature control
Temperature control of SIRe maintains the
exhaust temperature to approx. +40 °C. If the
temperature should exceed anyway there is
an overheating alarm. For more information
see the manual for SIRe.
Fan replacement
1. Determine which of the fans is not functioning.
2. Disconnect the cables to 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 a electric coil (E)
1. Mark and disconnect the cables to the electric
coil.
2. Remove the mounting screws securing the
coil in the unit and lift the coil out.
3. Install the new coil in reverse order to the
above.
Replacing the water coil (W)
1. Shut off the water supply to the unit.
2. Disconnect the connections to the water coil.
3. Remove the mounting screws securing the
coil in the unit and lift the coil out.
4. Install the new coil in reverse order to the
above.

Draining the water coil (W)
The drain valves is on the underside of the
coil. It can be accessed via the service hatch.
Trouble shooting
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, check also the fol-
lowing:
• Power supply to electric heater coil; check
fuses and circuit-breaker (if any).
• That the overheat protection for the motors
has not been deployed.
For units with water coil, check also the following:
• That the water coil is air free.
• That there is enough water flow.
• That incoming water is heated enough.
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 mains 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.
