1. Introduction

These operating instructions are applicable for the compressor units KC 100 and KC 200.

Description: compressor unit with direct current motor

Type: ___________________________________

Machine no.: ___________________________________

Please read these operating instructions carefully to enable a safe operation.

1.1 Owner’s responsibility

These operating instructions are part of the product. The owner/ operator has to consider on own authority:

 Operating and maintenance staff has access to these operating instructions always.
 All advices and safety regulations have to be fulfilled during shutdown and operating.
 These operating instructions have to be retained for further utilization.

1.2 Copyright

The duplication of text, technical data, drawings or similar is prohibited and demands the agreement of the
manufacturer.
Technical changes at the compressor unit stay reserved for the manufacturer.

1.3 General advices

The company Koci Elektromaschinen GbR determined that requirements regarding to spare parts and their
delivery, information for reparation or questions about technical issues of the compressor can be handled
only with the correct type or machine number.
If you did not purchase the compressor directly from the manufacturer please first contact your provider.

Additionally it is prohibited to remove the appliance rating plate.

2. Warranty and complaints

The legal foundation of our guarantee management is the German Civil Code. But please consider the
following regulations:

 Work carried out on our compressors under guarantee is only done in our workshop as a matter of

principle because the machines are classified as easy to transport. In case of contact by others any
guarantee claim cannot be asserted.

 Equally guarantee does not apply, if the compressor has been modified or altered without

consultation and approval by our company.

 The guarantee is limited to the compressor only and includes material and manufacturing faults.

 Faults resulting from natural wear and tear, improper use, installation or insufficient maintenance are

disregarded. Wear and tear elements are:

 Solenoid discharge valve
 Non-return valve
 Pressure switch
 Air filter
 Fuse

Furthermore the tube cooler is excluded from guarantee in case of traceable use as carry handle,
what is not allowed and results destruction of itself.

 We reserve the right to determine how and by whom the repairs are to be made.

 Costs that may arise as an after-effect of the compressor’s breakdown will not be accepted by our

company.

3. Reference of utilization

3.1 conventional utilization

The compressor units with DC motor are designed for versatile applications in which a compressed air
supply is needed to permanent disposition.
The compressor is provided solely for production of compressed air. Any other use is considered improper.
The manufacturer is not responsible for any damages resulting from improper utilization – the risk carries
the operator by himself.
Correct use includes also the compliance with the manufacturer’s regulations of installation, operating and
maintenance.

3.2 unconventional utilization

The compressor unit must not be used in hazardous areas - it is not protected against explosions.
Without additional air treatment compressed air from oil lubricated compressors is not suitable for the filling
of breathing air equipment and use in dentistry or for operations where compressed air comes directly into
contact with food.
Compressed air must never be directed at people. The concentrated energy causes a life-threatening
situation.

4.2 Technical description

The compressor unit with DC motor and control unit is a compact, powerful unit in block manner, which is
composed of two main parts, the single cylinder – compressor and the DC motor as a drive source.
Furthermore, we would like to mention following principal technical details that are integrated into the
compressor and contribute to increased safety and functionality.

General area: Area control block: Field electric machine:

 intake silencer with air filter
 4 rubber mounts for vibration

damping

 tube cooler
 compressed air tank/ pressure

container (delivery on request)

To ensure the electrical connection security and the corresponding control over the compressor, a control
light outside the device signals the respective operating.
An integrated momentum balance in the engine reduces vibration and provides a quiet and low-wear run.
For further noise reduction the compressor units are fixed on four rubber mounts and completed with an
intake silencer and an exhaust box on the discharge valve.

 solenoid discharge valve1
 pressure switch
 non-return valve
 safety valve
 silencer for the discharge air
 antifreeze pump with

antifreeze reservoir(installation
on request)

 power relay

 suppression equipment

 thermostats

 low voltage protection

 operating voltage independent

of the control voltage

 ensure a low control current

 security protection by circuit

board against false engaging
from the outside of the
compressor
