Dryer Protection
The fixed speed units are provided with a phase sequence relay.
For all models, the high-pressure shut-down switch stops the compressor motor when the pressure in the
refrigerant circuit reaches the upper set-point of the switch.
After tripping:
• The switch must be reset manually by pressing its reset knob and by accessing the protection
menu, on the electronic regulator, and pressing the Enter key.
The compressor motor has a built-in thermic protection. If the thermic protection trips, the compressor motor
will be stopped. The compressor will restart when the motor windings have cooled down, which may take
several minutes.
