5. STORAGE AND TRANSPORT
The manufacturer ships the compressor in a transport packaging. This protects the device from
damage during transport.
Risk of damage to pneumatic parts.
The compressor must be transported only when all air has been vented. Before
moving or transporting the compressor, release all the air pressure from the tank
and pressure hoses and drain condensate from the tank and from the condensate
separator on the dryer.
Original packaging must be kept for eventual return of the device. If possible,
always use the original compressor packaging for optimal protection of the
product. If it is necessary to return the product within the guarantee period, the
manufacturer does not guarantee for damages caused by incorrect packaging of
the product.
Transport the compressor in an upright position, always secured by transport
fixing elements.
Protect the compressor from high humidity, dirt and extreme temperatures during
transport and storage. Do not store together with volatile chemical substances.
If it is not possible to keep the original packaging, dispose of the packaging in an
environmentally friendly way. Transport cardboard can be recycled with old paper.
It is not permitted to store and transport the device outside the defined
conditions, see below.
5.1. Ambient conditions
Products can be stored in rooms and means of transport that are free from any traces of volatile
chemical substances under the following climatic conditions:
Temperature
from –25°C o +55°C, in 24h to +70°C
Relative humidity

8. PRODUCT FUNCTION
8.1. Compressor with adsorption dryer
(Fig. 1) The air pump (1) draws in air through the inlet filter (7) and supplies compressed air through
the connecting hose into the adsorption dryer (8). From the inlet to the dryer module, the air is first
cooled in the integrated cooler (26) and then moves through the condensate separator (32), entering
the active chamber with adsorbent (27), where the air is dried. A portion of the air is fed into the
second, regenerated chamber, where this air is used to remove moisture from the adsorbent, after
which it is vented to the atmosphere. The active chamber switches on a cyclical basis. The dry air
then passes through the non-return valve (3) into the air tank (2). Air drying efficiency (the pressure
dew point) is determined by the dew point sensor located in the air tank.
It is not necessary to drain the air tank.
8.2. Compressor in cabinet
(Fig. 3) The soundproof cabinet provides compact covering of the compressor, dampens noise
efficiently, providing sufficient exchange of cooling air. Its design makes it suitable for use in rooms
where low noise levels are required. The fan under the compressor pump provides cooling of the
compressor, it is in operation at the same time with compressor motor or after switching on the
temperature switch at temperature above 40 °C. After cooling the cabinet area approximately under
32°C, the fans turn off automatically.
The dryer display (34) is located on the front panel of the cabinet.

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.
