After compressor stops due to water level abnormality, drain pump is operated intermittently, i.e. 5 min ON,
5 sec OFF and 5 min ON. (*1) The intermittent operation is executed regardless of recovery of water level
abnormality during the intermittent operation. (*2) When the water level abnormality can not be recovered,
the latter 5 min ON operation is continued until recovery of the abnormality. (*3)
Even though the water level
abnormality could be recovered
during intermittent operation, the
operation shall be carried out
without exception.
If the abnormality could not be recovered
during intermittent operation, the latter 5
min ON operation is continued until
recovery of the abnormality.
Water level abnormality shall be cancelled simultaneausly when the unit is turned off with remote control after
recovery of the water level abnormality. When the unit is turned on with remote control thereafter, compressor
starts operation 2 minutes later from the remote control ON. (Below diagram showsan example of the case
that the water level abnormality is recovered during the former 5 min intermittent operation.)
