Low Temperature Error:
The internal temperature of the machine has fallen below that at which it can operate.
This message appears when the temperature falls to 5°C (41°F) or lower during startup or to 2°C (35.6°F) or lower during operation.
Operation cannot be continued. Turn off the sub power.
Bring the installed location to a temperature at which operation is possible (20°C to 32°C [68°F to 89.6°F]), allow the machine to come to room temperature, and then turn on the power.
