1.1 FUNCTIONAL DESCRIPTION

Ingersoll Rand refrigerated air dryers remove moisture from compressed air. Moisture is detrimental to pneumatically
operated appliances, controls, instruments, machinery and tools.
Compressed air enters the patented aluminum heat exchanger where it is cooled down to the dew point temperature in two
different stages: In the first air/air sector compressed inlet air is cooled thanks to the colder compressed air coming out
Air counterflow from the condensate separator. In the second refrigerant / air sector, compressed air temperature is further
lowered to the dew point temperature. During this two stages almost all the oil and water vapours contained in compressed air
outlet.
are condensed to liquid and successively be separated from the compressed air in the condensate separator and drained out
by the automatic drain. At this point the obtained cold air re-enters counterflow the initial air / air exchanger and it is reheated
by the inlet hot air with the consequence of energy recovering and also reduction of the relative humidity contained in the
outflowing air.
This dryer can be easily installed into various pneumatic systems in which dry air is required or desired. Please refer to
Principles of Operation for complete operating details.
The dryer comes provided with all the control, safety and adjustment devices, therefore no auxiliary devices are
needed.
A system overload not exceeding the maximum operative limits can worsen the operational performance of the dryer
(high dew point), but it will not affect its safety.
The electric diagram (attachment B) shows the minimum protection degree IP 42.
Improper grounding can result in electrical shock and can cause severe injury or death.
This product must be connected to a grounded, metallic, permanent wiring system or an equipment-grounding
terminal or lead on the product.
All grounding must be performed by a qualified electrician and comply with national and local electrical codes.
In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for
the electric current.
Ground must be established with a bare grounding wire sized according to the voltage and minimum branch circuit
requirements.
Ensure good bare metal contact at all grounding connection points, and ensure all connections are clean and tight.
Check grounding connections after initial installation and periodically thereafter to ensure good contact and
continuity has been maintained.
Check with a qualified electrician or service technician if the grounding instructions are not completely understood, or
if in doubt as to whether the product is properly grounded.

1.2 USE OF THE MACHINE IN SAFE CONDITIONS

This system has been designed and manufactured in compliance with the European safety directive in force,
therefore any installation, use and maintenance operations must be performed respecting the instructions contained in
this manual.
Because an air dryer is pressurized and contains rotating parts, the same precautions should be observed as with
any piece of machinery of this type where carelessness in operation or maintenance could be hazardous to personnel.
In addition to obvious safety rules that should be followed with this type of machinery, safety precautions as listed below
must be observed.
1. Only qualified personnel shall be permitted to adjust, perform maintenance or repair this air dryer.
2. Read all instructions completely before operating unit.
3. Pull main electrical disconnect switch and disconnect any separate control lines, if used, before
attempting to work or perform maintenance on the unit.
4. Do not attempt to service any part while machine is in an operational mode.
5. Do not attempt to remove any parts without first relieving the entire air system of pressure.
6. Do not attempt to remove any part of the refrigeration system without removing and containing
refrigerant in accordance with the EPA and local regulations.
7. Do not operate the dryer at pressures in excess of its rating.
8. Do not operate the dryer without guards, shields and screen in place.
9. Inspect unit daily to observe and correct any unsafe operating conditions.
