ERROR DETECTION
This unit has built-in error detection. If you see an error code show on the
screen (E1, E2, E4) please contact customer service and notify them of which
code your unit is showing. If the code is E1 or E2, you will need your unit
repaired professionally, as the temperature sensor is likely damaged. E4 means
the internal temperature of the unit is too low, so the A/C will be shut off until
the unit warms up again. If you see the E4 code, please turn off the unit and
wait at least one hour before attempting to use it again.
