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 TRANSPORTATION
Upon receiving your OMI 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 at a maximum temperature of
50 °C, and a specific humidity non exceeding the 90 %. Should the stocking time exceed 12 months, please contact
the manufacturer. If the device is to be used, make sure the site where it will placed, guarantees:
