PRODUCT DESCRIPTION
6. VARIANTS
The compressor is manufactured according to its intended application in the following variants:
DK50-10S/M
Compressor with membrane air dryer in a compact mobile cabinet.
DK50-10S/M
7. PRODUCT FUNCTION
7.1. Compressor with membrane dryer
Fig. 2 The compressor aggregate (1) draws in air through an inlet filter (7) and compresses it,
feeding it to the cooler (10) through the filter (8) and the non-return valve (3) into the dryer (9), and
feeds the clean and dry air into the air tank (2). The connected apparatus draws the compressed
air from the air tank until the pressure drops to a default preset level on the air-pressure switch (4)
switching the compressor on. The compressor again compresses air into the nozzle until the
maximum pressure is reached and the compressor switches off. The pressure hose is vented
through the relief solenoid valve (12) once the compressor unit is shut off. The safety valve (5)
prevents the pressure in the air tank from rising above the maximum allowed value. The air tank
pressure gauge (19) displays the current level of pressure in the air tank.
The dryer ensures the continuous drying of the compressed air. Condensate from the filter is
automatically released into a condensate collection vessel (16). Constant output pressure is
maintained by the pressure regulator (24). The pressure is displayed on the pressure gauge
regulator (20). The power switch (22), connector (23), hour counter (21) and compressed air outlet
connector (18) are installed on the outlet panel (25).
7.2. Compressor cabinet
Fig. 1, Fig. 2 The cabinet is compact and soundproof, while the fan (15) under the compressor
aggregate and the cooler fan allow the sufficient exchange of cooling air. The fans also operate
when the compressor motor is running or when the temperature in the cabinet rises above 40°C.
The fans automatically switch off once the space in the cabinet is cooled to below 32°C. The
compressor is equipped with 2 casters with brakes (29) in front and 2 casters without brakes (30)
The compressed air from a compressor is not suitable for the operation of
breathing appliances or similar equipment

PRODUCT DESCRIPTION

in the back. They can be replaced by packaged rubber feet.
The main switch is located on the front face of the cabinet (31).
Risk of compressor overheating.
Make sure that there are no obstacles at the cooling air inlet into the cabinet
(around the bottom part of the cabinet) and at the hot air outlet on the top back
side of the cabinet.
If the compressor is placed on a soft floor, e.g. carpet, create space between
the base and the floor or the cabinet and the floor, e.g. underlay the footings
with hard pads to ensure sufficient cooling of the compressor.

INSTALLATION
Risk of incorrect installation.
Only a qualified professional can install the compressor and place it into
operation for the first time. His obligation is to train the operating personnel on
the use and maintenance of the device. He shall confirm installation and
training of operators by an entry into the installation record (see Annex).
8. INSTALLATION CONDITIONS
The compressor may only be installed and operated in dry, well-ventilated and dust-free
rooms with conditions stated in Technical data.
Risk of damage to the device.
Do not operate the device in outdoor environment or in humid or wet rooms.
Explosion risk.
Do not install the device in any rooms, in which explosive gases, dusts or
flammable liquids may be present.
The compressor must be installed in such a way, that it is accessible at all times for
operation and maintenance and label on the device is accessible.
The compressor must stand on a flat, sufficiently stable base (be aware of the compressor
weight, see chap. Technical data).
Ensure the air delivered by the compressor meets the requirements for its intended use
before installing the compressor. Refer to the technical data of the product for this purpose.
The supplier of the final product must classify and evaluate compliance with the intended
application.
Any other use or use above this framework is not considered to be proper use. The
manufacturer is not responsible for damages that arise from such use. The operator/user
assumes all risk.
Cabinet-mounted compressors can only be operated in areas with continuous
air circulation and away from any sources of heat or direct exposure to
sunlight.
Risk of damage to the device.
The equipment must be located at least 100 mm from a wall in order to ensure
proper cooling air circulation. Failure to comply with such spacing may cause
damage to the compressor and cabinet!
9. COMPRESSOR ASSEMBLY
Unpack the compressor from the packaging.
9.1. Manipulation and fixation removal
Put the compressor at the place of operation
Use a hex key to rotate the stabilizer screw (X) down to the stop to the position - the
air pump will reach the operating position (Fig. 3).

INSTALLATION
NP-DK50-10SM-5_03-2020 18 03/2020
11. ELECTRICAL CONNECTION
11.1. Electrical connection
Risk of electric shock.
Connect the mains power cord to the compressor connector. The compressor
is equipped with a DF11 mains power module, which contains an IEC C14
power connector with a thermal fuse and the mains switch. Make sure this
connection complies with local electrical codes. The mains voltage and
frequency must comply with the data stated on the equipment's label.
The D11 fuse and switch module must be kept in an easily accessible location in case the
equipment has to be safely shut down in an emergency.
The connection to the power distribution box must be limited by a current protection device
at max. 16 A.
Risk of fire and electric shock.
The electrical cord cannot touch any hot parts of the compressor. It may
damage the insulation!
Risk of fire and electric shock.
If any electrical cord or air hose is damaged it must be replaced immediately
The equipment is equipped with C14 power connector with the V-lock system.
The C13 plug may also be equipped with the V-Lock system, which protects the
compressor and mains plug from coming loose unexpectedly.
11.2. Grounding instructions
The product connects to the mains with a grounded plug. The power-supply cord and its
plug may be connected only to a properly installed and grounded socket in accordance
with all local laws and regulations.
Risk of electric shock.
A faulty power-supply cord with a plug or a faulty socket may lead to the risk of
electric shock.
If you have any doubts about the product’s proper connection to the mains,
consult a qualified electrician or service technician. Do not modify the original
socket! Contact a qualified electrician.
Only power-supply cord (included in the packaging) with a matching line-
voltage configuration may be connected to the compressor power inlet. The
mains voltage and frequency must comply with the data stated on the device’s
label.
11.3. Connecting the product to the mains
The compressor connects to the mains using a power-supply cord (included in the packaging) that
has a product-side IEC60320 C13 socket and a mains-side plug in compliance with the standards
of the country of the intended use of the product (e.g. CEE(7) VII / C13).
The power-supply cord with a socket and plug is designed for the current and voltage levels of the
rated current and voltage of the product. The minimum cross-section of the bare conductors of the
cord is 0.75 mm2.

INSTALLATION
03/2020 19 NP-DK50-10SM-5_03-2020
12. FIRST OPERATION
Check whether the compressor has been set to the operating position (Fig. 3)
Check that all compressed air line connections are secure. (see chapter 10)
Ensure electrical connections are secure and properly completed. (see chapter 11)
12.1. Switch on the compressor
Turn the power switch (22) into the “I” position on the rear side of the compressor (Fig. 1)
and the main switch (31) on the front face of the cabinet (Fig. 2)
Compressor - At first operation the air tank is pressurized until it reaches a presets level when the
compressor automatically switches off. As the air is used, the compressor works in automatic
mode, switched on or off by the pressure switch. During operation, the air dryer removes humidity
from the supplied compressed air.
The compressor is not equipped with an emergency power supply.
