INSTALLATION MANUAL
AIR HEATER TYPE DXC
Some checks can only be performed when the heater is
running. Do the following:
1. Reconnect the air heater to the power supply.
2. Switch on the air heater.
3. Check if the heater operates without problems. See
chapter if any errors occur.
4. Check the air heater’s combustion efficiency. If
necessary:
–
Adjust the burner settings (see §3.2).
10.3 Maintenance of the burner unit
The burner unit is an important part of the air heater and
requires special maintenance.
To perform maintenance on the burner unit, do the
following:
1. Disconnect the ignition and ionisation cables from
the burner unit.
2. Disconnect the burner manifold from the gas valve.
This is a clamp coupling.
3. Remove the burner assembly from the air heater,
4. Check the burner for damage, corrosion and align-
ment of the separate burners.
a. Clean with a brush.
5. If necessary, clean the electrodes.
CAUTION!
Do not twist the electrode out of shape.
6. Check the inside of the heat exchanger for dirt and/
or damage. If necessary:
–
Clean the heat exchanger.
7. Disassemble the motor part from the flue fan. The
housing can remain on the heater.
8. Clean the inside of the flue fan.
9. Check the air supply and the flue discharge for dirt
and clean it.
10. Reassemble the burner unit. If necessary:
–
Use new gaskets.
10.4 Extensive maintenance in
poultry sheds
WARNING!
Air heaters that are used in poultry sheds
must be cleaned and inspected after every clean-out,
before disinfection and the spreading of sawdust on the
floor.
CAUTION!
The heat exchanger can be cleaned with a
pressure washer. Do not use a pressure washer to clean
parts that contain electronics, such as the electric motor
or the machine cover.
1. Use compressed air or a soft brush to clean the
remaining parts from the air heater. Focus on the
following parts:
a. The inside and outside of the body.
b. The fan blades and motor.
c. The temperature sensor.
2. Remove all dust from the motor. Accumulated
dust acts as insulation and can cause the motor to
overheat.
3. Use a brush to remove any baked on dust.
4. Clean the burner unit (see §10.3).
5. Switch on the air heater and let it heat for a while.
This burns off any remaining dust particles.
6. Stop the heating process.
7. Cover the air heater when it is fully cooled off. This
protects it from dirt or dust.
8. Make sure the air heater is electrically isolated.
9. Disinfect the poultry shed and spread the sawdust.
10. Remove the cover from the air heater. The heater is
ready to be used.
