STORAGE AND TRANSPORT
The compressor is shipped from the factory in a transport packaging. This protects the device from
damage during transport.
The original compressor packaging must be used for transport whenever
possible. Transport the compressor in an upright position, always secured with
transport fixation.
Protect the compressor from moisture, dirt and extreme temperatures during transport
and storage. Store the compressor in its original packaging in a warm, dry, and dust-free
area. Do not store near any chemical substances.
Keep the packaging material, if possible. If not, please dispose of the packaging material
in an environmentally-friendly way. Packaging cardboard can be recycled with old paper.
The compressor may only be transported when all air pressure has been vented.
Before moving or transporting the compressor, release all air pressure from the
tank and hoses and drain condensate from the air tank.
Storing or shipping the equipment in any conditions other than those specified
below is prohibited.
Ambient conditions for storage and transport

8.2.4. Condensation and filtration unit
The compressor may be additionally fitted with a condensation and filtration unit (KJF).
The KJF ensure that the compressed air from the air tank is cooled in the cooler and the
condensate is captured in the filter and automatically separated from the pneumatic distribution
system. The compressed air is filtered at the same time.
8.2.5. Equipotential bonding socket
The socket allows an equipotential bonding. (Fig. 10)

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 pump is 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 air through an inlet filter (8) and compresses it, feeding it to the cooler
(14) through the filter (15) and the check valve (3) into the dryer (9), and feeds the clean and dry
air 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.
For the membrane dryer to work as intended, the dryer is connected directly to the air tank without
the use of a check valve. As the membrane dryer contains selective membrane fibres, there is a
small amount of air leakage through them (about 0.5 bar/30 min)
This is why there is a gradual, slow drop in pressure even when there is no demand for
compressed air (from the air tank), however, this is not a malfunction.
The pressure vessel does not need to be drained.
