. Press PRETRIP CHECK key.
The PRETRIP key initiates a check of all normal operating modes.
Upon initiation, the unit will cycle through all operating modes at 30
second intervals. The display will show “PPPP” at the beginning
and will show various unit data during the pre-trip cycle. The final
PRETRIP mode is Defrost. When Defrost ends, PRETRIP will be
complete.
This is not a self-diagnosing pretrip test. No specific pretrip alarms
will be generated. Pretrip must be monitored by the user to verify
that the unit operates through all cycles.
