NOTE
Items [2] to [5] are optional or may be existing
items of plant. Refer to your Ingersoll Rand
distributor / representative for specic
recommendations.
LOCATION IN THE PLANT
The compressor can be installed on any level oor
capable of supporting it. A dry, well ventilated area
where the atmosphere is clean is recommended. A
minimum of 1m (3ft) should be left all around machine
for adequate service access and ventilation.
Adequate clearance needs to be allowed around and
above the machine to permit safe access for specied
maintenance tasks.
Ensure that the machine is positioned securely and on
a stable foundation. Any risk of movement should be
removed by suitable means, especially to avoid strain on
any rigid discharge piping.
CAUTION
Screw type compressors [1] should not be
installed in air systems with reciprocating
compressors without means of isolation such
as a common receiver tank. It is recommended
that both types of compressor be piped to a
common receiver using individual air lines.
CAUTION
The use of plastic bowls on line lters and other
plastic air line components can be hazardous.
Their safety can be aected by either synthetic
coolants or the additives used in mineral oils.
Ingersoll Rand recommends that only lters
with metal bowls should be used on any
pressurised system.
CAUTION
The standard compressor unit is not suitable
for operation in temperatures liable to cause
freezing as Condensate water is liable to be
produced in the after cooler and receiver where
tted.
Refer to your Ingersoll Rand distributor for
further information.
DISCHARGE PIPING
Discharge piping should be at least as large as the
discharge connection of the compressor. All piping
and ttings should be suitably rated for the discharge
pressure.
It is essential when installing a new compressor [1],
to review the total air system. This is to ensure a safe
and eective total system. One item which should be
considered is liquid carryover. Installation of air
dryers [3] is always good practice since properly selected
and installed they can reduce any liquid carryover to
zero.
It is good practice to locate an isolation valve close to
the compressor and to install line lters [4].
It is a requirement for air dryers covered under AirCare
that correctly sized Ingersoll Rand pre and afterlters
are installed.
