NP-DK50 DI-15_08-2020 17
Compressed air connection
Air inlet (WALL)
Connect the compressed air line from the central distribution line to the
WALL quick coupling - inlet compressed air (if a central air distribution line is
available).
Air outlet (OUT)
Connect the pressure hose to the medical ventilator to the OUT quick
coupling on the compressed air outlet.
Air from the central distribution system is automatically connected through
the compressor to the OUT outlet 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 in the supply of continuously pressurized air at
the outlet of the compressor.
The maximum rated air pressure for the WALL quick coupling is 5.5 bar
/ 80 psi. Please note that the air supply from the central distribution line
entering the compressor must be medical grade air (particulate size
and moisture content). The compressor does not modify the air from
the central distribution line.
The hose connecting the compressor to medical ventilator must not
pass through a cold environment i.e. placed on the ground. It should be
as short as possible with no kinks (this may cause water to condense
inside the hose).
The compressor must not be used for supplying air to the medical air
central distribution pipeline system.
Electrical connection
The compressor comes with a plug containing an appropriate
protective contact (ground) adhere to local electrical regulations. The
voltage and frequency of the mains 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 equipment
can be safely disconnected from the power supply in case of an
emergency.
The relevant current circuit must be protected.

OPERATION
18 NP-DK50 DI-15_08-2020
First operation
Make sure that the pump inside of device was unsecured.
Check that the connection to the compressed air supply is correct.
Check for proper connection to the main power supply. Before the
equipment is plugged in, make sure that the voltage and frequency shown

Switch on the pressure switch to position “I”.
OPERATION
The equipment may only be operated by the trained staff!
In case of emergency, switch the equipment off at the switch and pull
out the main power plug.
Switching the compressor on
The compressor is switched on at the main power switch by putting it in
position "I". The compressor operates in one of the following modes
depending on the pressure in the central distribution line and on the
consumption of compressed air:
STANDBY / indicator flashing - when pressure in the central compressed air
line is sufficient and the power switch is on, the compressor is in standby
mode. The equipment functions as a backup compressed air source,
monitoring the pressure in the central compressed air line, with the
compressor coming online if the pressure drops to a pre-set level.
RUN / indicator permanently displayed - the compressor operates at low
pressure in the central compressed air line or if the equipment is not
connected to a central compressed air line.
Running the compressor
The display shows the value of outlet pressure in BAR or PSI units. Change
of units is available, contact your service representative.
Total operating hours indicator displaying total operating hours. For
preventive maintenance hours see chapter Maintenance.
Alarm system
All alarm states of the equipment are states of the middle priority technical
alarm according to EN 60601-1-8. Each alarm state is indicated by the
corresponding visual and auditory signal (see Chapter 2 - Display Unit and
Chapter 3 - Technical Data).

OPERATION
NP-DK50 DI-15_08-2020 19
Alarm states indicate a potential failure of the device. Therefore, it is not
possible to deactivate the alarm signals.
All alarm signals are non-latching –after the triggering event no longer exists
the alarm signals stop.
Operator’s position. No specific operator’s position is required. However, the
operator should remain in the range of visual or audible alarm signal, which
may depend on the actual operating conditions.
Low pressure. The signal is active when the equipment is started up until
the compressor reaches the low pressure limit. The signal may be activated
during operations due to a lack of seal in the compressed air section past the
compressor, increased air consumption or an equipment fault. The visual
indication flashes and the buzzer signal is activated.
Call on an authorized maintenance service provider in the event of a fault.
High pressure. In the case of pressure rise above the high pressure limit
indication flashes and the buzzer signal is activated. The air pump will be
turned off until the pressure drops.
High temperature . If the temperature rise above 65°C indication flashes
and the buzzer signal is activated. Check if the cooling of compressor is not
restricted or ambient temperature is not too high.
Loss of power. In the case of loss of power symbol flashes and the buzzer
signal is activated. Check the electricity supply. After 5 minutes, the signal is
turned off.
Operators must quickly secure a backup air source for the patient in the
event any of these signals activate during equipment operation.
Test of the alarm system functionality is performed automatically when
the equipment is switched on by a short testing activation of the visual
and auditory alarm signals (light up of LED indicator and auditory
pulse).
Cleaning and replacing the air inlet filter
At least once a week take out and clean the inlet filter (5) located on the back
side. Wash the filter in warm soapy water, rinse thoroughly and allow it to
dry. Insert the clean filters so that the intake openings are completely
covered by the filters.
