23. Cooler
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).

4. OPERATION
INSTALLATION AND FIRST OPERATION
Do not use the compressor immediately after unpacking as it will not
adjust for ambient temperature.
Only qualified personnel can install the compressor and put it into
operation for the first time. The installer shall train the operating
personnel in the use and routine maintenance of the appliance.
Installation and training of personnel should be acknowledged by the
installer‘s signature on the certificate of installation.
Prior to start-up, four screws for transport stabilization must be
removed. If the compressor is switched on without removing the
stabilizers, the compressor could be permanently damaged.
The compressor does not contain a backup power supply.
Never block the air intake filter in backside and the ventilating outlets
on the upside of the appliance.
If the compressor is equipped with main source of air, standby source
of air must be available.
Removal of transport stabilizers
On the bottom of the unit are four M6
stabilizing screws that must be removed
before start-up. They are marked with a
red warning washer.
Please retain the stabilizing screws for
future transport of the compressor.
Wheels installation

according to figure.

OPERATION
10 NP-DK50 DS-6_10-2010
Compressed air connection
The medical compressor is equipped with fast-on couplings WALL (10) and
OUT (9) on the rear of the cabinet.
To the fast-on coupling OUT (9) -output compressed air- connect the
pressure hose leading to the applicable appliance/respiratory apparatus.
To the fast-on coupling WALL (10) -input compressed air- connect
pressurized air from a central distribution system, if applicable. The air from
the distribution system is automatically connected through the compressor to
the outlet OUT port. In this configuration, the compressor serves as a backup
source of compressed air. If the air pressure from the central distribution
system is reduced, the compressor automatically switches on and there is no
interruption of continuously pressurized air at the output from the
compressor.
Please note that the air supply from central distribution entering the
compressor must be medical grade air (particulate size, humidity.) The
compressor does not modify the air from central distribution.
The hose connecting the compressor to the breathing apparatus must
not pass through a cold environment i.e. placed on the ground. It
should be as short as possible with no kinks (it may have impact on
condensation of water inside the hose).
Electrical connection
The compressor comes with a plug containing an appropriate
protective contact (ground.) Adhere to local electrical regulations. The
mains voltage and frequency must comply with the specifications on
the Data Label.
The electrical cord must not be stressed or have any tension exerted
upon it, and must always be free.
The socket must be accessible for safety reasons so that the appliance
can be safely disconnected from the mains supply in case of emergency.
The relevant current circuit must be safeguarded.
Connection of the ground connection (12) to other appliances must adhere
to local electrical regulations.
Fasten down the electrical cord through the holder (13).
First operation
Make sure that the stabilizing screws used during transport were
removed.
Check that the connection to the compressed air supply is correct.

OPERATION
NP-DK50 DS-6_10-2010 11
Check for proper connection to the mains supply.
Switch on the pressure switch (11) to position “I”.
After the compressor is put into operation, it shall work in one of the following
modes depending upon the pressure level in the central distribution and upon
air consumption.
STANDBY – When there is sufficient pressure in the central air distribution,
the mains switch is on and the POWER (8) indicator is on, the compressor
is idle. The device operates as a standby source of air as it checks the
pressure in the central air distribution and, if that pressure falls, the
compressor switches on.
When pressure is low in the central air distribution, or if the device is not
connected to the central distribution, the compressor permanently works. If
there is no air consumption at the output, the device switches to STANDBY
mode. When air consumption resumes, the compressor automatically
switches on.
During operation, the device drains off the entrapped condensed water from
pneumatic circuits via automatic filter separators into a vessel.

PERSONNEL
In case of emergency, switch the appliance off at the switch and pull
out the mains plug.
Switching the compressor on
The compressor is switched on at the mains switch (11) by putting it in
position ”I“. Switching on is signaled by the green indicator (8).
Running the compressor
The green indicator POWER (8) is lit up during operation. Display displays
the value of output pressure with accuracy ± 5% in BAR or PSI units. An
indicator is lit on the display next to the relevant unit. Ask serviceman for a
change of display of units if necessary. After pressing the TIME (6) button,
the display shows the number of hours in operation. Indicator DRYING (4)
displays the drying status. Green indicates satisfactory drying; yellow
indicates unsatisfactory drying. If the yellow indicator DRYING (4) stays on,
make sure that the air consumption from the compressor did not exceed the
output flow according to specification. If air consumption is within normal
parameters, contact servicing centre.
The decrease in output pressure is indicated by alarm PRESSURE (2) which
sounds an alarm and illuminates the yellow indicator. The alarm is activated
if the output pressure does not reach the required level and also in the
interval after the compressor is turned on until it reaches the required
pressure. If the alarm stays on, make sure that the air consumption did not
exceed the output flow according to specification. If air consumption is within
normal parameters, contact servicing centre.
Cooling failure is indicated by alarm TEMP (3) which sounds an alarm and
illuminates the yellow indicator. The device must be immediately
disconnected from the electrical mains and cooled down. Cooling failure
activation may indicate that the venting holes were covered, the filter in the
bottom part of the compressor is contaminated or the compressor works in
environment with higher temperature. If none of these circumstances apply,
a malfunction has occurred and service is required.
Alarm MAINS (5) is activated upon the interruption in the powering of
compressor.
Illumination of yellow indicator BATTERY (7) signals low battery. During the
equipment operation the battery is recharged automatically. If the yellow
control light does not turn off after 24 hours of the equipment operation, it is
necessary to change the battery. The battery powers the MAINS (5) alarm
and has no impact on other functions of the device. Entrust an authorized
service provider with its replacement. Exchange the battery for identical type
with the original one - NiMH 9V 200mAh.
