4. OPERATION

INSTALLATION AND FIRST OPERATION

Do not use the compressor immediately after unpacking as it will not

adjust to the 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 equipment.

Installation and training of personnel should be acknowledged by the

installer‘s signature on the installation certificate.

Prior to start-up must be unsecuring the air pump inside. If the

compressor is switched on with securing the air pump, the device

could be permanently damaged.

The compressor does not contain a backup power supply.

Never block the air intake filter on the backside or the vent outlets on

the lower of the equipment.

If the compressor is equipped with a main source of air, the standby air

source must be available.

Any modification of this equipment is forbidden!

If this equipment is used nearby other devices, the equipment must be

observed in order to verify normal operations in the configuration it will

be used.

Devices may be affected electro-magnetically!

You may notice a “new product” odour when you first place the

product into service (for a short period of time). This odour is

temporary and does not impede the normal use of the product. Ensure

the space is properly ventilated after installation.

OPERATION

16 NP-DK50 DI-19_11-2023

Unlocking of air pump

Before the first use it is necessary unlock the air pump inside to the

normal position.

Unpack the device and place it on a flat floor.

Transport position

Air pump inside is locked, two red screws protruding out.

Normal position

Before use it is necessary unlock the air pump inside. Screw both screws

inward using included wrench Nr. 5.

Before the later transport of device, it is necessary lock the air pump to

the transport position.

OPERATION

NP-DK50 DI-19_11-2023 17

Installation of couplings for connecting hoses

Use a box wrench to install the couplings supplied with the product into the

openings in the rear panel. Beware of possible confusion - the marking on

the coupling must match the marking on the product. Use the supplied plastic

sealing rings to seal the connection.

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.

OPERATION

18 NP-DK50 DI-19_11-2023

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.

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

on the equipment are the same as provided by the power connection.

• 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:

OPERATION

NP-DK50 DI-19_11-2023 19

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).

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.

OPERATION

20 NP-DK50 DI-19_11-2023

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.

Cleaning the compressor

To clean the compressor, use a detergent that contains no abrasives,

chemical solvents or other corrosive agents.
