Installation and operation
5.1.1 Commissioning
Before you operate the new EN series compressor for the
first time, install it at your site according to ELGi’s
Installation specifications.
For safe operation of the compressor, the servicing
technician performs a series of checks on the compressor
and the systems to which the compressor connects. The
technician will explain to the compressor operator how to
operate and maintain the equipment. This procedure is
referred to as the commissioning process.
The commissioning of your compressor is a necessary
safety step. The general operating conditions of the
equipment, including the cleanliness of the ambient
atmosphere, the temperature and ventilation, are checked.
Technical details relating to your system, such as
particulars of your electrical installation, are verified. The
commissioning process includes familiarizing your
compressor operator with all aspects of the compressor’s
normal running and dealing with unusual situations.
Please make preparations according to the instructions
provided in the Installation section for your EN Series
compressor to be commissioned. Ensure that the location
chosen meets the requirements of accessibility,
ventilation, and safety. Provide electrical power as
recommended in the Installation section. Select air pipe
lines and receivers for your system according to the tables
provided in the same section.
After completing the commissioning process, the
technician will fill in the commissioning report and the
warranty card.
5.1.2 Unpacking
Unpack the compressor from the packing case by
removing the nails or pins. Unscrew the bolts as you hold
the compressor to the base of the crate.
Once you have separated the packing material, check the
contents against the packing list. The compressor ships
with the following items:
 The key to doors
 The operation and maintenance manual
 A checklist of parts of the machine
 An electrical drawing
Tools may be provided on request. If any components are
missing, contact ELGi immediately.
5.1.3 Handling
 If the compressor consists of a lifting bail, then use only
the bail to lift the bail machine. If no bails exist, lift the
bail machine using slings. Always use slings and not the
lifting bail to airlift compressors by helicopter.
 Prior to lifting, inspect the lifting bails and points of
attachment for cracked welds; for cracked, bent,
corroded or otherwise degraded members; and for loose
bolts and nuts.
 Make sure the entire lifting, rigging, and supporting
structure has been inspected, is in good condition, and
has a rated capacity of at least the net weight of the
compressor. If you are unsure of the weight, then weigh
the compressor before lifting it.
 Make sure the lifting hook has a functional safety latch,
or equivalent, and is fully engaged and latched on the
bail.
 Use guide ropes or equivalent to prevent twisting or
swinging of the machine once it has been lifted clear off
the ground.
 Do not attempt to lift the compressor in high winds.
 Keep all personnel away from the compressor when it is
suspended.
 Do not lift the compressor higher than necessary.
 Make sure the lift operator is present throughout the
duration that the compressor is suspended.
 Set the compressor down only on a level surface that is
capable of supporting at least its net weight plus an
additional 10 per cent allowance .
