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 approximately + 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.
2.1 ACCEPTANCE AND TRANSPORTATION
At the moment the customer accepts the delivery, he must fully inspect the dryer to verify its integrity and the presence of
all the items listed in the shipping documentation.
Eventual claims for missing and/or damaged parts must be addressed directly to our facility or to the closest
reseller, within 8 (eight) days from the date on which the goods have been received.
It is mandatory to keep the dryer always in vertical position, as indicated by the symbols present on the packaging. For
eventual displacements, use devices having sufficient capacity for the weight of the machine.
Remove the packaging after having positioned the dryer in the installation site. We suggest to keep the original packaging
at list for the duration period of the warranty of the machine. Anyhow, do not forget to dispose the various materials in
compliance with the relevant rules locally in force.
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.
