1. GENERAL INFORMATION
PURPOSE
The EKOM DK50 DE is a medical air compressor that supplies clean, oil-
free compressed air for use with medical ventilators.
CONTRAINDICATIONS AND SIDE-EFFECTS
There are no contraindications or side-effects known.
OPERATOR'S RESPONSIBILITY FOR PATIENT SAFETY
Instructions for use is an integral part of the equipment and must be kept
with the compressor. Careful review of this manual will provide information
necessary for correct operation of the equipment.
Rx only
US Federal law restricts the sale of this device by or on the order of a
physician.
MARKINGS
Products marked with the CE mark of compliance meet the safety
requirements of the European Union (93/42/EEC).
WARNINGS
The safety of operating personnel and trouble-free operation of the
equipment are ensured only if original parts are used. Only accessories
and spare parts mentioned in the technical documentation or expressly
approved by the manufacturer can be used.
If any other accessories or consumable materials are used, the
manufacturer cannot be held responsible for the safe operation and
functionality of the equipment.
The warranty does not cover damages resulting from the use of
accessories or consumable materials other than those recommended by
the manufacturer.
The manufacturer assumes responsibility for the safety, reliability and
function of the equipment only if:
- Installation, calibration, amendments, extensions and repairs are
performed by the manufacturer, one of its representatives or a service
provider authorized by the manufacturer
- The equipment is used in accordance with the Installation, Operation and
Maintenance Manual
GENERAL INFORMATION
4 NP-DK50 DE-LF-9_02-2019
The Installation, Operation and Maintenance Manual accurately describes
the design of the compressor and its compliance with safety and technical
standards. The manufacturer reserves all rights to its wiring diagrams,
procedures and names.
General safety warnings
The equipment is designed to operate safely when used correctly. Please
note the following safety measures to avoid injury or damage.
Equipment operation must comply with all local codes and regulations.
Original packaging should be kept for the possible return of the unit. Only
original packaging ensures optimal protection of the equipment during
transport. If it is necessary to return the equipment during the warranty
period, the manufacturer is not liable for damages caused by incorrect
packaging.
The user must immediately notify the supplier if any problem occurs during
the use of the equipment.
This product is not intended for use in areas where there is a risk of an
explosion. Do not operate the compressor in the presence of flammable
anesthetics.
Never feed oxygen or nitrous oxide into the compressor. Compressor
components are not approved for oxygen or nitrous oxide use.
Electrical system safety warnings
The equipment must be connected to ground. I order to assure proper
grounding, connect the compressor to a receptacle marked "hospital
grade."
Before the compressor is plugged in, make sure that the voltage and
frequency of the mains specified on the equipment are the same as the
power mains.
Before operating, check for possible damage to the equipment and any
connections. Damaged pneumatic and electrical lines must be replaced
immediately.
If a technical failure occurs, immediately disconnect the equipment from
the mains (pull out the main power plug).
During repairs and maintenance, ensure that:
- The main power plug is removed from the power socket
- Compressed air lines are disconnected
- All pressure has been released from the air tank
Only a qualified technician can install this equipment.

USE
The equipment can be installed and operated only in a dry, ventilated and
dust-free area. Climatic conditions for operation - see Technical data.
The compressor must stand on a flat and stable base.
The compressor must not be exposed to rain. The equipment must not be
used in humid or wet environments. Never use the compressor in the
presence of flammable liquids or gases.
Before connecting the compressor to respiration equipment, make sure
that it meets the requirements of the respiration equipment. Refer to the
Technical data for this purpose.
Any use other than the compressor‘s intended use is not considered to be
safe. The manufacturer is not responsible for any damages that result if
the compressor is used for any other purpose. Risk is exclusively
assumed by the operator/user.
STORAGE AND TRANSPORT
The compressor is shipped from the factory in transport packaging with the
pump stabilized, protecting it from damage during transport.
For transport, always use the original packaging and secure the compressor
in the upright position.
Protect the compressor from humidity, contamination and extreme
temperatures during transport and storage. A compressor in its original
packaging should be stored in a warm, dry and dust-free area.
Keep the packaging material, if possible. If not, dispose of the packaging
material in an environmentally-friendly way. Cardboard can be recycled.
Prior to transport it is necessary to secure the motor inside the
compressor (Chapter 5).

The equipment uses an oil-free piston compressor (8) driven by a low-maintenance
electric motor. Compressed air is cooled in the cooler (14) where condensed water is
separated into a separate tank (12). Compressor working pressure is set using the safety
valve (11). Constant output pressure is maintained by the pressure regulator (2).
