INSTALLATION RECOMMENDATIONS
It is recommended that the compressed air is treated prior to entry into
the distribution system and also at critical usage points / applications.
Installation of compressed air dryer to a previously wet system could
result in additional dirt loading for point of use filters for a period
whilst the distribution system dries out. Filter elements may need to be
changed more frequently during this period.
For installations where oil-free compressors are used, water aerosol and
particulate are still present, general purpose and high efficiency grades
should still be used.
A general purpose filter must always be installed to protect the high
efficiency filter from bulk liquid aerosols and solid particulate.
Install purification equipment at the lowest temperature above freezing
point, preferably downstream of after-coolers and air receivers.
1. Open inlet valve slowly to gradually pressurise the unit.
2. Open outlet valve slowly to re-pressurise the downstream piping.

In the unlikely event that a problem occurs on the equipment, this troubleshooting guide can be used to identify the probable cause and remedy.
Troubleshooting should only be attempted by competent personnel. All major repair, and calibration work should be undertaken by a
Ingersoll Rand trained, qualified and approved engineer.
HIGH PRESSURE DROP
High pressure drop will result in low pressure gauge readings or intermittent operation of the downstream equipment.
Possible Cause
Filtration has not been correctly
maintained.
The inlet parameters have changed.
There is a pressure loss from the system.

4. INSTALLATION
Point of use purification equipment should be installed as close to the
application as possible.
Purification equipment should not be installed downstream of quick
opening valves and should be protected from possible reverse flow or
other shock conditions.
Purge all piping leading to the purification equipment before
installation and all piping after the purification equipment is installed
and before connection to the final application.
If by-pass lines are fitted around purification equipment, ensure
adequate filtration is fitted to the by-pass line to prevent contamination
of the system downstream.
Provide a facility to drain away collected liquids from the purification
equipment. Collected liquids should be treated and disposed of in a
responsible manner.
Refer Page number 52, Table:1, Annex A
5. START UP OPERATION
Do not open inlet or outlet valves rapidly or subject unit to excessive
pressure differential or damage may occur.

Action Required
If the element has been installed longer than 6 months ensure that they are both changed.
If the inlet flow-rate has increased ensure that the filters are re-sized accordingly.
If the inlet temperature has increased verify that the filters are within specification. Ensure that the oil
vapour removal filters are re-sized accordingly.
If the inlet pressure has changed ensure that the filters are re-sized accordingly.
Contact Ingersoll Rand for details on particle counting and air quality air measurement.
Check for leaks in the piping and at connection points.
Check to see if the downstream flow-rate demand has increased.
