5.4 Installation and operation
these may erode the internal components and also
contaminate the oil and filters.
 Do not allow hot air from additional equipment to blow
towards the compressor.
 If you operate in high dust applications like rice mills,
cement, flour mills, etc., clean and replace the filters
more often.
 Good practice is to have overhead lifting in the
compressor room to facilitate any major overhaul. If an
overhead hoist is not available, you should be able to
use a mobile crane or forklift truck in your compressor
room at a minimum.
5.1.5 Ventilation and exhausting hot air
 Ensure adequate ventilation in the compressor
installation area. Your compressor has a ventilating air
requirement of 600 to 1200 cfm.
Guidelines to compressor ventilation setup:
Follow these guidelines when providing ventilation for the
compressor:
 Provide openings close to the floor level on walls/
partitions close to the air suction side of the compressor
 Provide exhaust openings close to the ceiling for hot air
exit.
 Ensure the air velocity in the supply and exhaust ducts
does not exceed 13.1ft/s (4m/s).
 Determine air velocity during commissioning using an
anemometer.
 Do not connect cool air inlet ducts directly to the
compressor inlet side.
 To eliminate transmission of vibrations, provide a soft
bellows connector between the duct and the
compressor.
 Contact ELGi in case you need to provide a duct
connection or filter fitment on the compressor.
 Do not direct forced flow of cool air towards the
compressor.
 Locate the compressor such that hot air from other
machines is not directed towards it.
5.1.6 Electricals
Electricals 60Hz
You must provide a lockable main switch unit with pre-
connected slow-blow main fuses as per industrial safety
regulations. Power supply should be 208/230V 1 Ph 60Hz
with earth PE or 208-230V/460V 3 Ph 60Hz with earth PE.
The fuse and cable specifications for 208-230V, 60 Hz 1
Ph, 208-230V 60Hz 3ph and 460V 60Hz 3ph power
supplies appear in the table below.
You must also provide a switching fuse unit with pre-
connected slow-blow main fuses as per industrial safety
regulations. Power supply should be 208/30V 1 Ph with
earth PE or 208-230V/460V 3 Ph with earth PE.
The fuse and cable specifications for 208-230V, 60 Hz 3 Ph
and 460V 60Hz 3ph power supplies appear in the table
below.
Electricals 50Hz
You must provide a switching fuse unit with pre-connected
slow-blow main fuses as per industrial safety regulations.
The power supply should be 380V/400V/415V, 50Hz, 3
phase with (PE) earthing.
The fuse and cable specifications for 380V/400V/415V,
50Hz, 3 Ph power supplies appear in the table below.
You must provide a switching fuse unit with pre-connected
slow-blow main fuses as per industrial safety regulations.
The power supply should be 380V/400V/415V, 3 phase
with Neutral.
The fuse and cable specifications for 380V/400V or 415V,
50Hz, 3 Ph power supplies appear in the table below .
Ensure that only authorized electricians perform electrical
work. Study the electrical circuit diagram before starting
work.
NOTE
Suspended particulate matter should be less than 150 spm
to achieve the specified consumable life.
Guarantee is void if the compressor is operated above its
intended pressure.
