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
settings.
