2. CHAPTER
2.1 INSTALLATION OF THE COMPRESSOR AND CONNECTIONS
The floor on which the compressor is mounted should be capable of carrying the weight of compressor
and should be flat and dry. There is no need to fixing (anchorage bolt etc) to the floor.
The compressor room should be easily accessible and sufficiently illuminated.
For adequate service, the compressor room should have a clearance of at least 1.5 m from ceiling and
1m from the wall.
Fire and corrosion causing conditions should be prevented in the operation region.
No pipe load (swaggering connections or tensions arise from environmental variations) should be
relayed to compressor by external connections.
Make sure that the air supply equipment is suitable to the operating pressure of the piping and fittings
and is damage free.
Select the diameter of the air supply, dryer and line filters according to your air supply capacity. (It is
beneficiary to select piping of big diameter considering future development of your company).
Establish a separate line for condense discharge of your filter and dryer and air tanks (water discharge
line); this way the floor of the compressor operating place does not unnecessarily get wet.
Put an air exit and electric box in your compressor room for general purpose
Your compressor is manufactured for indoor operation.
In case of different needs in relation to compressor or air supply contact service or sale representative.

2.2 COMPRESSOR ROOM VENTILATION

In order to maintain the operation temperature at a specific value, place your compressor at a place that
adequate air flow is provided. The temperature that compressor operates should be at least 2 and at
most 40 °C. Do not place your compressor where the temperature is less than + 2 °C and if necessary
heat the compressor room.
If you think that there will not be sufficient amount of air flow in the room of operation; it is necessary to
make room ventilation or you must discharge the outgoing hot air the compressor to outside. When
doing this, the outgoing hot air of compressor should not return. For this reason the hot air outlet and
room air inlet should not be on the same side. If necessary use a fan for discharging the hot air from the
room. Place this fan to the closest point of the compressor hot air outlet
Avoid not expose the compressor cooler to direct sun light or regional strong winds.
Avoid the compressor room being subjected to heat or dust emitted by central heating boiler or
generator type of equipment.

2.3 ELECTRICAL CONNECTIONS

Ensure that the electrical installation of your compressor is performed by a qualified electrician.
Your compressor is designed to operate with three phase system. The voltage and frequency data are
written on the template of your compressor and in the "Technical data" part of this handbook. Suitable
cross sections for supply cable selection are shown in "3.2 Energy cable dimension "section.
Your compressor is designed to operate in + 2 to + 40 °C ambient temperature and at most 1000
meters above the sea level. At higher altitudes, some corrections must be made by taking into account
of environmental conditions. The data related with this is shown in detail at the maintenance "motor
maintenance" section 5 of this handbook.
Attach the grounding cable to the outer side of compressor with a screw marked with
the grounding line operates properly.
Working without grounding may be dangerous for the work safety of the personnel and
compressor. In case of failure and critical situation, please properly install your grounding line
in order to prevent death
