Stopping the refrigeration unit
Notes
ADVICE
The battery failure circuit will not function during motor drive.
ADVICE
If you press the cabin controller’s [RUN/STOP] switch a second time, the refrigeration unit will go
“STOP” and cooling will stop. When the refrigeration unit goes “STOP”, the time is displayed in
the digital display.
If the room temperature is – 29ºC or lower, or 32ºC or higher, the room temperature display may not
show the temperature in 0.5ºC units, but there is no problem with operation.
● Do not run and stop the refrigeration unit by turning the power supply circuit breaker on
and off or by unplugging or plugging in the power plug. If this is done, the power supply
circuit could break down or it could cause an electric shock.
● Do not let rain or water get in the power supply box’s receptacle. If it does, it could cause
an electric shock during motor operation or unit operation.
(1) Unit operation
1The unit will start operation approximately 20 seconds after the cabin
controller's [RUN/STOP] switch is set to “RUN”.
2The unit will stop for approximately five seconds when the ELEC./DIESEL
changeover switch setting is changed.
(2)
During motor drive operation, the unit will run at 1st speed, and will either cool or heat.
(1) Power voltage and capacity
Prepare a power supply in which the rush voltage on
the refrigeration unit side can be secured to 340 to
380 V or 370 to 415V when the motor starts.
(2) Motor power supply
3-phase AC 380V-415V 50Hz
ADVICE
This cabin controller is equipped with a function that stores the setting temperature in
memory from the previous time the refrigeration unit was used (memory function). However,
to be sure, please check the setting temperature in the top row of the digital display.

Operation
CAUTION
CAUTION
Operation
● When AUTO START/STOP is selected
Cooling operation will be carried out automatically if the room temperature is higher than the
setting temperature, and heating operation will be carried out automatically if the room
temperature is lower than the setting temperature. When the room temperature reaches -1°C of
the setting temperature, the motor will automatically stop, and the compressor, condenser fan
and evaporator fan will stop. Heating will not take place if the temperature is "-7°C" or less
below the setting temperature.
● When CONT.RUN is selected
If the room temperature is higher than the setting temperature, the cooling operation will take
place, and if lower, the heating operation will take place. Continuous operation will take place by
repeating cooling and heating.
