Whisper operation (Only for sub-engine drive)
Pressing the [WHISPER] switch enables the whisper operation and one more
press on the switch returns it to the normal operation.
When the whisper operation is enabled, the
(whisper operation icon) lights
on the icon bar.
Even when the whisper operation is enabled, the setting is reset as the unit
operation is stopped. Press the [WHISPER] switch and set the whisper
operation at every time when the whisper operation is necessary.
NOTE
●
The whisper operation is the function to run the sub-engine at the slow speed
revolution only. Use this function when it is necessary to suppress the sound of
unit operation temporarily during stopping time of the vehicle and so on.
(The whisper operation is acceptable only when the drive setting is "ENGINE" in
the state that the controller is activated.)
●
The setting can be changed so that the whisper operation setting will not be
reset even if the refrigeration unit stopped the operation. When you need this
setting, contact your nearest dealer.
