5. Commissioning
5.1 Location and assembly references
 Before the initial start-up the compressor unit must be screwed tightly on its location
 The compressor unit must be protected from dust and dirt to ensure the conventional functionality.
 The connection of the compressor should be chosen in accordance to the guidelines for the
installation of compressed-air lines with a slight incline towards the boiler.
 Enough cooling should be provided.
 In case of installation in a vehicle, the cooling direction must no work against the airflow.
 The connection of the compressor unit should be done with a flexible hose connection.
 Please use the rubber mounts for placement and storing.
 The device has IP66 (splash-proof). So please protect the air supply (flexible hose connection
towards air filter) and all the other parts from intensive water contact.
 The environment is not allowed to be humid or wet and no gases or liquids should be places nearby
the compressor.
under voltage protection and control light
1. Under voltage protection
The operator should provide an operating voltage between -10 % and +20 % of the rated voltage.
The following faults occur, when the operating voltage does not lie correctly:
a) The compressor cannot be switched on – Fault: operating voltage under -10% of rated voltage.
b) The compressor turns off automatically – Fault: operating voltage under -25% of rated voltage.
c) The compressor turns off automatically and can be switched on again only after the control
switched was turned off and a waiting time of about 10 seconds. – Fault: short interruption of
operating voltage or control line (loose connection).
A correct and safe operation is only guaranteed, when the connection follows the description of the
manufacturer or a confirmed (by the manufacturer) compliant circuit.
You have to be able to switch off the compressor at any time.
Any self-made changes in the original circuit during the legal warranty period cause an immediate
loss of any claims.
2. Control light
The control switch and light have to be installed within the operator’s viewing area.
An illumination of the control light indicates:
 Loose connection – Motor turns off automatically
 excess temperature – Motor turns off automatically and can be switched on after its cooling (ca. 45
min).
Please always investigate the reason of an occurring fault or glowing control light and arrange quick
remedy to avoid consequential damages.
