NOTE
Items [2] to [5] are optional or may be existing items of plant. Refer
to your Ingersoll–Rand distributor / representative for specific
recommendations.
LOCATION IN THE PLANT
The compressor can be installed on any level floor capable of
supporting it. A dry, well ventilated area where the atmosphere is clean
is recommended. A minimum of 150mm (6 inches) should be left at the
rear and 1m (3ft) at the sides of the machine for adequate service
access and ventilation.
Adequate clearance needs to be allowed around and above the
machine to permit safe access for specified 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.

INSTALLATION / HANDLING
CAUTION
The use of plastic bowls on line filters and other plastic air line
components can be hazardous. Their safety can be affected by
either synthetic coolants or the additives used in mineral oils.
Ingersoll –Rand recommends that only filters 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 fitted.
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 fittings 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 effective 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 filters [4].
It is a requirement for air dryers covered under Aircare that correctly
sized Ingersoll–Rand pre and afterfilters are installed.
