1. GENERAL INFORMATION
1.1 FUNCTIONAL DESCRIPTION
Drying systems with refrigeration cycle have been designed for a cost effective elimination, with minimal overall dimensions, of the
condensate contained in compressed air by cooling it down to approxi 3°C.
The operation principle of the dryers described in this manual is shown in the air and refrigeration circuit diagrams (attachment A).
The air delivered to the services is virtually humidity free, and the condensate collected in the separator is discharged through
appropriate draining devices. In order to limit the size of the machine and to avoid condensation on the external surface of the tubing,
before exiting the dryer, treated air is counter current pre-heated by the air entering the system.
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 performances 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. The user must provide the dryer
with a line protection and a ground terminal.
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.
Any installation, use and maintenance operation requiring to access the internal parts of the dryer must be
performed by qualified personnel.
The manufacturer will not be liable in case of uses different or nor complying with those foreseen in this
manual.
2. INSTALLATION
2.1 ACCEPTANCE AND HANDLING
Upon receiving your Ingersoll Rand air dryer, please inspect the unit closely. If rough handling is detected, please note it on your
delivery receipt, especially if the dryer will not be uncrated immediately. Then obtain the freight carrier's signed agreement to any noted
damages: this is a precondition for any insurance claims by the customer.
It is mandatory to keep the dryer always in vertical position, as indicated by the symbols present on the packaging. For handling, use
devices having sufficient capacity for the weight of the machine.
Remove the packaging after having positioned the dryer in the installation site. For unpacking, refer to section 2.3.
Under no circumstances should any person attempt to lift heavy objects without proper lifting equipment (i.e., crane, hoist, slings or fork
truck). Lifting any unit without proper lifting equipment, may cause serious injury. Use fork lift channels where provided.
2.2 STORAGE AND INSTALLATION LOCATION
If not in use, the dryer can be stored in its packaging in a dust free and protected site between 32°F (0°C) and 120 °F (50 °C), and a
specific humidity not exceeding 90 %. Should the stocking time exceed 12 months, please contact your local Ingersoll Rand authorized
distributor.
If the dryer is not used, it will be placed in a site with the following conditions:
The machine must be protected from atmospheric agents and not directly exposed to sun light.
A seating base flat and capable to hold the weight of the machine.
Ambient temperature complying with the nominal data of the dryer.
The dryer should be located in a clean area, without forced air draft that can affect the fan control system.
Make sure to leave sufficient clearance (20 inches, 500 mm) around the dryer in order to allow an adequate
cooling of the machine and for maintenance and/or control operations.
The incoming air must be free from smoke or flammable vapours which could lead to explosion or fire risks.
