function of the appliance only if:
- installation, calibration, amendments, extensions and repairs are
performed by the manufacturer or its representative, or a service provider
authorized by the manufacturer
- the appliance is used in accordance with the Installation, Operation and
Maintenance Manual
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 schemes,
methods and names.

GENERAL INFORMATION
NP-DK50 DS-6_10-2010 3
General safety warnings
The appliance is designed to operate safely when used correctly. Please
note the following safety measures to avoid injury or damage.
Operation of the device must be in compliance with all local codes and
regulations.
The original packaging should be kept for the possible return of the unit.
Only original packaging ensures optimal protection of the appliance during
transport. If it is necessary to return the appliance during the warranty
period, the manufacturer is not liable for damages caused by incorrect
packaging.
If any problem occurs during use of the appliance, the user must notify his
supplier immediately.
This product is not intended for use in areas with risk of explosion. Do not
operate the compressor in the presence of flammable anesthetics.
Never put oxygen or nitrous oxide into the compressor. The components
are not approved for oxygen or nitrous oxide use.
Electrical system safety warnings
The appliance must be connected to earth (grounded). To assure correct
grounding, connect the compressor to a receptacle marked "hospital
grade."
Before the compressor is plugged in, make sure that the mains voltage
and frequency specified on the apparatus are the same as the power
mains.
Before operating, check for possible damage to the appliance and the
connection system. Damaged pneumatic and electrical lines must be
replaced immediately.
If a technical failure occurs, immediately disconnect the appliance from the
mains (pull out the mains plug).
During repairs and maintenance, ensure that:
- the mains plug is removed from the power socket
- pressure pipes are disconnect
- pressure is released from the air tank
Only a qualified technician can install this appliance.

USE
The appliance 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, sufficiently stable base.
The compressor must not be exposed to rain. The appliance must not be
used in humid or wet environments. Never use the compressor in the
presence of flammable liquids or gasses.
Before connecting the compressor to a respiratory appliance, make sure
that it meets the requirements of the respiratory appliance. 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. This risk is assumed only
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 can 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.
Before moving or transporting the compressor, the pressure in the air tank
and hoses must be released and any condensed water must be drained.
Secure the motor before shipping.
Prior to transport it is necessary to fix motor inside the compressor
(Chapter 5.)

The compressor contains of an oil-free piston (16) driven by a low-maintenance single-
phase electric motor. Compressed air is cooled in a cooler (23) where condensed water is
separated into a vessel (14). Incoming air passes through two filters (15, 21) and
undergoes double filtration as it passes through the system (19). The model with a
membrane dryer is intended for applications that require a higher level of air dryness.
Constant pressure at output is maintained by pressure regulator (20). The built-in air tank
(18) enables peak air consumption of 200 L/min.
The device may be used as a standby source of air. In this configuration, the respiratory
equipment is supplied with compressed air from the central air distribution of the medical
facility. Air pressure in the central distribution is sensed by a pressure sensor. If the
pressure is sufficient, the compressor stays in STANDBY mode. If the pressure falls, the
control unit automatically puts the compressor into operation.
When the compressor is used as the main source of air, the control unit determines its
operation according to the current need for air. If air consumption is zero, the device
switches to STANDBY mode.
The compressor is equipped with indicators for output pressure (1), operation hours (6),
power status (8), drying sufficiency (4) and battery condition (7). The acoustic and optic
alarms activate to warn of high operating temperature (3), low output pressure (2) and loss
of power (5).
