The compressor can be installed on any level floor capable of supporting it.
A dry, well ventilated area where the atmosphere is as clean as possible is
recommended.
The area selected for the location of the compressor should be free of dust,
chemicals, metal filings, paint fumes and overspray. Heat and water with
chemicals present in the air can cause corrosion.
Hard surfaces may reflect noise with an apparent increase in the decibel
level. When sound transmission is important, a sheet of rubber or cork can
be installed beneath the compressor to reduce noise. Flexible piping may be
required.
See the general arrangement drawing for minimum space requirements for
normal operation and maintenance.
Minimum space in front of the control panel door as required by national or
local codes shall be maintained.
Ambient temperatures higher than 40°C (104°F) shall be avoided, as well as
areas of high humidity.
A minimum of 1 m (3��3 ft) clearance all around the compressor is
recommended�� If headroom is restricted, then the exhaust should be
ducted or deflected away from the compressor��
Screw type compressors 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 tank using individual air
lines��

DISCHARGE AND CONDENSATE PIPING


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.
A flexible element should be installed between compressor and the
discharge piping to attenuate vibration transmission.
One item which should be considered is liquid carryover. Installation of air
dryers (3) is always good practice since, when properly selected and installed,
they can reduce any liquid carryover to zero.
An air receiver dry tank (2) is recommended to ensure that the total system
volume is sufficient.
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. Discharge piping should not exert any unresolved
moments or force on the compressor.
It is good practice to install line filters (4).
Include a vent or drain trap (6) to vent the discharge pipework downstream
from the minimum pressure check valve located on the separator tank and
upstream of the first system isolation valve (7).
This compressor has an internal discharge check valve. An external check
valve is not required. An isolation valve (7) is required within 1 m (36 in) of the
compressor discharge.
There should be no plastic or PVC piping attached to this compressor
or used for any lines downstream with exception of condensate
removal lines��
The discharged air contains a very small percentage of compressor
coolant and care should be taken to ensure that downstream
equipment is compatible��
When two rotary compressors are operated in parallel, provide an isolation
valve (7) and drain trap (6) for each compressor before the common receiver.
Ensure the discharge piping is arranged to prevent water from being forced
into the non-operating compressor.
A wet tank (8) is recommended in cases where the air dryer is a regenerative
desiccant type to prevent short cycling the compressor during the purging
cycle when plant air demand is slow.
The built-in after-cooler reduces the discharge air temperature below the
dew point (for most conditions). Therefore, considerable water vapor is
condensed. To remove this condensation, compressor packages that include
a dryer have a built-in a condensate trap. It is recommended if the customer
does not have a dryer unit or receiver-mounted unit, that they install an
Ingersoll Rand condensate separator and trap.
A dripleg assembly and isolation valve should be mounted near the
compressor discharge. A drain line would be connected to the condensate
drain in the base.
