Version 1.1
If the compressor is anchored to the base on which it is installed, the tilt angle with respect to
the horizontal surface must not exceed 7°. Install the compressor in a facility where precip-
itation cannot reach. Choose a facility for installing the compressor with a minimum level of
dust. Install the compressor at least 1,5 m from walls.
If multiple compressors are installed, there should be a 1,5 m minimum distance between
each compressor. There should be a 4 m safety distance from the area of the operated equip-
ment connected to the compressor. The facility in which the compressor is installed must be
fitted with a combined extract-and-input ventilation system.
The facility where the compressor is installed should be provided
with air inflow equivalent to twice the compressor’s capacity.
The volume of extraction ventilation must not exceed 40% of the air inflow capacity of the input
ventilation in a facility where the compressor is installed and fitted with an extract- and input ven -
tilation system.
The compressor should not be installed in a facility where the temperature may drop below +5°С.
In order to extract hot air flowing out the compressor, an air duct may be used that is up to 3 m in
length and with a cross section 20% larger than that of the air-outflow orifice from the compressor’s
radiator. If an air duct longer than 3 m is used, additional duct fans should be used.
3.4 Connection to the compressed airline
Provide the throughput capacity of the compressed-air line in accordance with the perfor-
mance of the compressor. In order to avoid damage associated with seal failure of the com-
pressed-air line, the compressor should be connected via a flexible hose. All components of
the compressed-air line must have a working pressure no less than the compressor’s nominal
pressure. Use a pressure vessel with a capacity corresponding to the compressor’s perfor-
mance and the compressed air consumer.
3.5 Connecting to power supply
The compressor is not supplied with a power cable. The cable size must be chosen to ensure
that the maximum voltage drop not exceed 5 % of the nominal voltage value. Cable length
must not exceed 25 m. Ambient temperature in the facility must not exceed 40°C. The cable
must be sheathed with a fire retardant compound. An isolating switch must be fitted within
reach of the compressor to facilitate connection and maintenance.
