5.3 CLEANING THE MOTOR AND THE FAN

To clean the fan wheel and the motor, please proceed as follows:

• Loosen the fastening screws of the fan and remove the fan.
• Clean the motor with compressed air.
• Clean the fan wheel with a hard brush.
• Reinstall the fan.

5.4 CHECKING THE ELECTRICAL CONNECTIONS

After unplugging the power supply cable, check all electrical

connections as follows:

• Make sure that the connections are intact and properly seated.
• Remove any dirt and corrosion or replace the connections if

necessary

• Replace damaged wires or connectors if necessary

5.5 CHECKING AND TESTING THE BURNER

To access the burner:

• Unscrew the fastening screw of the burner
• Pull out the burner and perform the inspection and cleaning work

according to the instructions in the burner's operating manual

• Reattach the burner unit
• Perform the work steps required to measure the combustion

parameters and ensure a stable and clean combustion, which are
described in chapter 4

5.6 CHECKING THE THERMOSTATS

Proceed as follows to check the thermostats:

• Remove any connection ducts from the air outlet
• Locate the thermostats mounted on the inner wall of the air heater
• Clean the thermostats with a dry cloth and pay attention not to

kink or damage the capillary tube

5.7 CLEANING THE INSIDE OF THE DEVICE

For thorough cleaning the air heater can be washed with water both
on the inside and on the outside.
However, you have to observe the following:

• The power cable must be removed from the socket
• All inspection panels must be completely closed
•

When cleaning with a water jet, the maximum permissible

pressure is 70 bar with a distance below 30 cm

• All parts must have dried completely before the power cable is

reconnected

5.8 CLEANING THE HEAT EXCHANGER AND THE COMBUSTION

CHAMBER

To maintain the device's high efficiency, the cleaning work

described here must be performed at least once at the end of
each operating season, or several times in case of excessive soot
formation. The latter can occur, for instance, if the chimney draught
is not ideal, if low quality fuel is used, if the burner is improperly
adjusted, or if the device is switched on and off frequently.

06. Transport and repositioning

Hold the front handles when repositioning or transporting the device.
The heater will move on its rear wheels.

Before repositioning the device, make the following prepara-

tions:

• Switch off the device.
• Interrupt the power supply by removing the plug from the

socket.

• Wait until the heater has cooled down.

Only use the provided lifting gear for lifting the device. Attach ropes
or chains to the four lifting points. Before lifting the device make sure
that the lifting gear used is actually suited to lift the device. You will
find the weight of the device in the technical data table.

Do not try to lift the device with pure muscle power: The

heavy weight can cause serious physical damage.

07. Fault and troubleshooting

In case of a severe operational disruption, various safety devices can
cause a safety shutdown of the device. This is signalised as follows:

• at the control box

This is the block signal indicating that safety thermostat L2
has triggered. The reset button is located inside the burner
housing.

• at the burner

Safety shutdown signal indicating that the burner's flame
monitoring has triggered.

In the event of a safety shutdown, do not carry out two

consecutive restarts. Unburned fuel components can ac-

cumulate in the combustion chamber and might suddenly

ignite during the subsequent restart.
