9. PRODUCT FUNCTIONALITY
Compressor (Fig. 2)
The air pump (1) draws in atmospheric air through an inlet filter (8) and compresses it through a non-return valve (3) into an air tank (2) from which the device draws compressed air. If the pressure in the air tank drops to the switch-on pressure, the pressure switch (4) turns on the compressor and the compressor supplies compressed air into the air tank until it reaches the switch-off pressure, when the compressor switches off. The pressure hose is vented through the relief solenoid valve (13) once the air pumpis shut off. The safety valve (5) prevents the pressure in the air tank from rising above the maximum allowed value. The drain valve (7) drains condensate from the air tank. Compressed, oil-free filtered air is stored in the air tank ready for use. Condensate must be drained from the air tank at regular intervals (see Chapter 19.1).
Compressor with membrane dryer (Fig. 1) The air pump (1) draws in atmospheric air through an inlet filter (8) and compresses it, feeding it through the coolers (14) and the filter (15) into the dryer (9) and the dry, clean air is then fed through the non-return valve (3) into the air tank (2). A part of the air is released from the dryer with the captured moisture, which is manifested as a light air stream along the body of the dryer (9). Condensate from the filter is automatically drained at regular intervals into the collecting bottle via the condensate drain solenoid valve (16). The dryer ensures continuous drying of the compressed air. The drain valve (7) drains condensate from the air tank when drying performance is checked. Compressed, oil-free filtered air is stored in the air tank ready for use. The pressure vessel does not need to be drained.
Compressor with condensation and filtration unit(Fig. 3) The air pump (1) draws in air through an inlet filter (8) and compresses it through a non-return valve (3) into the air tank (2). Compressed air from the air tank flows through a cooler (10) that cools the compressed air. The condensed moisture is trapped in the filter (11) and automatically separates as condensate (12) into the collecting bottle. Compressed, oil-free filtered air is ready for use. Condensate must be drained from the air tank at regular intervals (see Chapter 19.1).
Compressor cabinet(Fig.4) The soundproof cabinetprovides compact covering of the compressor, allowing sufficient exchange of cooling air. With its design It can be placed in a dentist’s office as apart of furniture. The fan under the air pump of a compressor provides cooling of compressor and it is in operation at the same time with an engine of the compressor. After prolonged use the temperature in the cabinet may rise above 40°C, causing the cooling fan blower to automatically turn on. After cooling the cabinet area down to 32°C the fan blower turns off automatically.
Make sure that nothing impedes the free flow of air under and around the compressor. Never cover the hot air outlet on the top back side of the cabinet.
If placing the compressor on a soft floor such as carpet, create space for ventilation between the base and floor or the cabinet and floor, e.g. underpin the footings with hard pads.
For 8-10 bar compressor models, an hourly meter is installed on the pressure switch.

OPERATION
IN CASE OF EMERGENCY, DISCONNECT THE COMPRESSOR FROM THE MAINS (PULL OUT THE MAINS PLUG).
THE AIR PUMP HAS HOT SURFACES. BURNS OR FIRE MAY RESULT IF CONTACT IS MADE.
During prolonged operation of the compressor, the temperature in the cabinet may increase to over 40°C. At this point the cooling fan automatically switches on. After cooling the space to under 32°C, the ventilator switches off.
Automatic start: when pressure in the pressure tank decreases below the switch­on pressure, the compressor automatically switches on. The compressor automatically switches off when pressure in the air tank reaches the switch-off pressure.
The working pressure settings for the pressure switch set by the manufacturer cannot be changed. Compressor operation at a working pressure below the switch-on pressure indicates high air consumption (see the chapter Malfunctions)
Required drying performance can only be achieved when following the defined operating conditions!
Drying performance will decline and the achieved dew point will drop if the dryer is operated at any pressure below the minimum working pressure!
WHEN THE DRYER IS OPERATED AT AMBIENT TEMPERATURE THAT IS HIGHER THAN MAXIMUM OPERATING TEMPERATURE, THE DRYER MAY BE DAMAGED!
16. COMMISSIONING
Make sure all transport stabilizers were removed. Check that all pressurized air line connections are secure. Check to ensure power is connected correctly to the compressor. Check to ensure the switch is in the “I” position. Turn the switch (2) to the “I” position if found in
the “0” position. (Fig. 13)
For cabinet-mounted compressors, turn the switch (4) on the front side of the cabinet to the "I"
position; a green indicator indicates the device is in operation. (Fig. 13)
Check the connection of the cabinet connector to the compressor. (Fig. 11) Check to ensure the jumper has been removed from the terminal strip in the electrical panel for
cabinet-mounted compressors. (chap.14.1.)
Check the connection of the the cabinet pressure gauge hose to the compressor pneumatic
block. (Fig.4 and9)
The compressor is not equipped with a backup power supply.

DK50 2x2V/110
17. SWITCHING THE COMPRESSOR ON
(Fig. 13) Start the compressor at the pressure switch (1) by turning the switch (2) to the “I” position. Turn on the switch (4) on the front of the cabinet for compressors in the cabinet, the indicator will turn green.The compressor begins running, the air tank is filled, and the switching pressure and pressure switch turn the compressor off. The compressor operates in automatic mode, switched on and off by the pressure switch, depending on compressed air consumption. Check the values of the switch-on and switch-off pressure using the pressure gauge (3). A tolerance of 10% is acceptable. The pressure in the air tank must not exceed the permitted operating pressure.
Fig.13
Adjustments to the pressure range on the compressor’s pressure switch are prohibited. The pressure switch (1) was set up by the manufacturer and only a qualified technician trained by the manufacturer may make any changes to its settings.
Compressor – when first started and placed into service, the compressor fills the air tank until the
switching pressure and the pressure switch turn off the compressor. The compressor operates in automatic mode, switched on and off by the pressure switch, depending on compressed air usage.

Compressor with dryer – the compressor operates in the same manner as above, only the
compressed air passes through a cooler and a dryer that removes moisture from the compressed air.
Compressor with a condensation and filtration unit (KJF-2) - during usage by the device, the compressed air passes through the KJF-2 unit, where the air is cooled, filtered and condensed liquid is captured and automatically drained into a collecting bottle.
18. COMPRESSOR SHUT-DOWN
(Fig.13) Compressor shut-down for either service or any other reason is performed at the pressure switch (1) by turning the alternation switch (2) to the “0” position and pulling the mains plug from the socket. This disconnects the compressor from power supply. Then open the drain valve (Fig. 14) to decrease the pressure in the air tank to zero.

MAINTENANCE
19. DEVICE MAINTENANCE
Warning!
The operator shall ensure completion of repeated testing of the device at least once every 24 months (EN 62353) or at intervals defined by applicable national legal regulations. A record of these test results shall be completed (e.g. per EN 62353, Annex G) together with the measurement methods.
The device has been designed and manufactured to keep maintenance to a minimum. The following work must be performed to retain the proper and reliable operation of the compressor.
For 8-10 bar compressor models, an hourly meter is installed on the pressure switch.
The work below may only be performed by trained personnel as follows:
Before starting compressor maintenance work, it is necessary to check it the compressor can be disconnected from the device to ensure that the person using the device is not at risk of health damage and there is no risk of any other material damages!
Air pump components (head, cylinder, pressure hose, etc.) are very hot during and shortly after compressor operation – do not touch these components!
Repair works beyond normal maintenance can be performed only by qualified personnel or he manufacturer’s customer service. Use only spareparts and accessories approved by the manufacturer.
PROTECT EYESIGHT, WEAR GOGGLES, WHEN VENTING COMPRESSED AIR FROM THE COMPRESSED AIR CIRCUIT (AIR TANK).
BEFORE STARTING ANY MAINTENANCE WORK, FIRST DISCONNECT THE COMPRESSOR FROM THE MAINS (PULL OUT THE MAINS PLUG) AND VENT THE COMPRESSED AIR FROM THE AIR TANK.
