(about 3° C).
•
Now open the outlet air valve and then open gradually the intake air valve. In this way, the plant is gradually pressurized.

If the plant is overloaded over the max. use limits (see technical data), the dryer's performance will be remarkably lower but safety will not be in
danger.
Before disconnecting the dryer from electrical power supply, use COMMON ON/OFF key (1S4) to stop the dryer.
Otherwise wait 10 minutes before switching the dryer on again, in order to allow freon pressure re-balance.
5.0 MAINTENANCE

Perform the following after stopping the compressed air flow by closing the intake and outtake valves.
5.3 After 6 months
Isolate the machine before performing the following.
According to the room temperature quality and when summertime begins, clean the condenser with a low pressure air jet and clean the fins of the unit to
remove possible scales or deposits the might decrease its performance.
Check that the compressor power consumption values fall within the range detailed on the machine plate (see compressor product label).
6.0 CONTROL PANEL
The machines in this series are equipped with an electronic controller for the adjustment of the operating parameters. Adjustments can
be made using the digital panel, located on the dryer's front panel. Please note that the SET POINT & other control parameters
have been optimized and factory set. Although the set point value can be displayed, the ability to alter these factory settings
via the digital interface on the front panel has been removed to eliminate the possibility of unit damage caused by improper
