11. High-pressure switch
1) When the high-pressure switch operates, the operation of the compressor is terminated.
2) The compressor restarts after 5 minutes using [1] as an error count.
After restart, the error count is cleared when operation continues for 10 minutes or more.
3) An error is confirmed with the error count [10].
4) For the indicated contents of error, confirm using the check code table.
12 Control of compressor case thermo
1) The compressor stops when the case thermo of the compressor operated.
2) When the case thermo operated for approx. 80 seconds, E04 error code (same as serial error) is
displayed on the wired remote controller. → Refer to the Check Code.
3) When the case thermo is reset, the operation restarts.
