STORAGE AND TRANSPORT

The compressor is shipped from the factory in a transport packaging. This protects the device from

damage during transport.

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

Products may only be stored and transported in vehicles that are free of any traces of volatile

chemicals under the following conditions:

Temperature

–25°C to +55°C, 24 h at up to +70°C

Relative humidity

10% to 90% (non-condensing)

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.

Portable and mobile RF communications

equipment should be used no closer to any

part of the equipment, including cables, than

the recommended separation distance

calculated from the equation applicable to

the frequency of the transmitter.

Recommended separation distance

d=1,2√ P

d=1,2√ P, 80 MHz to 800 MHz

d=2,3√ P, 800 MHz to 2,7 GHz

where P is the maximum output power

rating of the transmitter in watts (W)

according to the transmitter manufacturer

and d is the recommended separation dis-

tance in metres (m).

Field strengths from fixed RF transmitters,

as determined by an electromagnetic site

survey a, should be less than the compliance

level in each frequency range b. Interference

may occur in the vicinity of equipment

marked with the following symbol:

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.

NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by

absorption and reflection from structures, objects and people.

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and

land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted

theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an

electromagnetic site survey should be considered. If the measured field strength in the location in which the

equipment is used exceeds the applicable RF compliance level above, the equipment should be observed to

verify normal operation. If abnormal performance is observed, additional measures may be necessary, such

as re-orienting or relocating the equipment.

b Over the frequency range 150 kHz to 80 kHz, field strengths should be less than 3 V/m.

Accessories

Accessories not included in the standard order must be ordered separately!

8.2.1. Automatic condensate drain

The automatic condensate drain (AOK) automatically drains condensate from the compressor’s air

tank based on a pre-set time interval. The condensate drain (AOK) is a suitable accessory for

compressor models without dryers.

8.2.2. Set of compressed air outlet filters

The compressor may be equipped with a set of filters if specified. The filter set may be equipped

with an air pressure regulator.

Where a different level of air filtration is required, this requirement must be

agreed upon with the supplier and specified in the order.

8.2.3. Filter set regulator assembly

The compressor may be equipped with a pressure regulator of the compressed air outlet if

specified. The regulator must be selected according to the application to the filter set, or separately

The regulator shall ensure constant pressure at the outlet.

8.2.5. 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.

8.2.6. 3KOM modules for controlling multiple compressors in Master-Slave functionality

A 3KOM control module may be ordered to manage the operation of 2 or 3 identical compressors

with the same pressure range in Master-Slave functionality. In use, the controller in the module

takes over the compressor switching function. The control module may be ordered in the

configurations shown in the following table.

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)
