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

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.
Packaging
Packaging materials are chosen with
consideration to the environment and are
therefore recyclable.

Safety
•
For all installations of electrically heated
products a residual current circuit breaker
300 mA
for fire protection should be used.
•
Keep the areas around the air intake and
exhaust grilles free from possible obstructions!
Troubleshooting
If the fans are not running or do not perform
properly, check the following:
• The power supply.
•

• That the motor's safety cut-out has not been
deployed.
• Functions and settings of the FC control
system, see the FC manual.
If there is no heat, check the following:
• Functions and settings of the FC control
system, see the FC manual.
For units with electrical heating, also check the
following:
• Power supply to electric heater coil; check
fuses and circuit-breaker (if any).
• That the overheat protection has not been
deployed.
Replacing the PC board
1. The PC board is located in the terminal box.
2. Mark and disconnect the cables to the PC
board.
3. Unhatch the board from its PCB snap-in
spacers and lift out.
4. Install the new PC board as above in reverse
order.

excessively or the electronics fail or overheat.
The cut-out will automatically reset when the
motor temperature has returned to within the
motor’s operating limits. Failure or damage to

Fan replacement
Fans are replaced through the bottom service
hatch. Alternatively the screws of the bottom
service hatch are slackened and the fans are
replaced through the top service hatch.
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.
For units with a water coil, also check the
following:
• That the water coil is air free.
