19. Cooler

The compressor contains an oil-free piston (11) driven by a low-maintenance single-phase

electric motor. Compressed air is cooled in the cooler (19) where condensed water is

separated into a separate tank (8). Incoming air passes through two filters (6,18)

undergoing double filtration as it passes through the system (14,16). Constant pressure at

the output is maintained by the pressure regulator (15). The built-in air tank (13) enables

peak air consumption of 200 L/min.

Backup ventilator compressed air source (applicable to compressors with WALL

connection)

Compressor air inlet (WALL) (5) is connected to terminal unit of the hospital central air

distribution through built-in non-return valve. Medical ventilator is connected to the

compressor outlet air connector. The compressor remains in STANDBY mode when the

central distribution air pressure is higher than compressor outlet air pressure. The air flows

from central distribution line through compressor air inlet (WALL), non-return valve and

compressor air outlet to the ventilator.

If the air pressure in central distribution drops below compressor outlet air pressure, the

controller automatically starts up the compressor, which delivers air directly to ventilator.

Air delivery from the compressor to the central air distribution pipeline is prevented by non-

return valve.

Primary ventilator compressed air source

The compressor continuously supplies compressed air directly to the medical ventilator

when the central compressed air distribution line is not connected to compressor air inlet

(WALL).

If air consumption is zero, the device switches to STANDBY mode.

The compressor must not be used for supplying air to the medical air

central distribution pipeline system. Do not connect compressor air

outlet to the central distribution pipeline system.

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, the 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 suction filter on the backside or the vent outlets on the

top 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 instruments, the equipment must

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

will be used.

Instruments 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.

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.

OPERATION

14 NP-DK50 DE-22_05-2023

Wheel installation

Wheels must be installed following the figure below for versions of the

compressor with wheels.

Compressed air connection

The given appliance or respiratory apparatus should be connected to the

OUT (3) quick coupler, as this is the outlet for compressed air.

Applicable to compressors with WALL connection (5):

Compressed air from the central distribution line is connected via the WALL

(5) quick coupling as this is the inlet for compressed air, if applicable. Air

from the 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.

Air delivery from the compressor to the central air distribution pipeline is

prevented by non-return valve.

Please note that the air supply from the central distribution line

entering the compressor must be medical grade air (particulate size,

humidity.) The compressor does not modify the air from the central

distribution line.

The hose connecting the compressor to the respiration equipment

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.

OPERATION

NP-DK50 DE-22_05-2023 15

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.

• Connection of the ground connection (7) to other equipment must adhere

to local electrical regulations.

• Fasten the electrical cord through the holder (10).

First operation

• Make sure that the stabilizing screws used during transport were

removed.

• Check that the connection to the compressed air supply is correct.

• Check for proper connection to the main power supply.

• Switch on the pressure switch (1) to position “I”.

The compressor will be operational once it is put into operation. 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 tank.

The following applies to device with additional equipment – WALL (5)

coupling:

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

line, the main switch 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

line and, if the pressure falls, the compressor switches on.

• When pressure is low in the central air distribution line, or if the device is

not connected to the central distribution line, the compressor is running. If

there is no air consumption at the outlet, the device switches to STANDBY

mode. When air consumption resumes, the compressor automatically

switches on.

During operation, the device drains the trapped condensed water from

pneumatic circuits via automatic filter separators into a separate tank.

Checking tightness of joints and inspecting the equipment

Test for leakage:

• Disconnect the outlet hose from the quick coupling OUT (3); compressed

air consumption will stop.

• Pressurize the air tank by releasing some air via a connected device.

• With the compressor off, wait at least 10 minutes before checking the

pressure level.

• If the pressure has dropped, use soapy water to find the leaky joint. Start

with the joints outside the case, and then test the ones inside the case

after removing the covers.

• Tighten or re-seal joints as necessary.

Inspect the equipment:

• Check the status of the compressor motor for balanced operation or noise.

• Check the condition of the hangers above the pump.

• Check fan functionality.

• Check the condition of filters (14,16). With regular operation, condensate

drains automatically. Verify this function by comparing the level of

condensate in the tank to the scale line indicating the maximum level. If

the level of condensate is above the scale line, replace the faulty parts.

• Examine the pump for:

- Defects in the crankcase

- Free movement of the crank shaft

• If necessary, replace any faulty parts.

Replacing filter elements

Before beginning, evacuate all compressed air from the tank, reducing

the tank pressure to zero and disconnect the equipment from the power

mains.
