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
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 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
Start up chapter 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.
