Standby Guidelines
Check for proper motor rotation. Condenser air must be drawn into the unit (see indicating flag on front
grille). To reverse rotation, stop the unit, disconnect power cord, and change polarity of plug.
For safe, reliable operation in standby mode, it is important to consider the following guidelines:
• NEVER connect the unit to a power source with the RUN/STOP switch in the RUN position.
• The power supply cable and circuit breaker must comply with the following:
• When multiple units are in use, each unit must be operated on its own electrical circuit. You should never
operate more than one unit on a circuit breaker.
• When preparing a circuit for operation of the refrigeration unit, a licensed electrician should be contracted. A
licensed electrician is familiar with all local ordinances and special requirements for your area and can
ensure that the circuits are properly designed and installed, and that connections are correct.
If unit is switched to Standby and the power plug is not plugged in, NO POWER is displayed.
3.6 START / STOP OPERATION
1. Check if AUTO START/STOP indicator is illuminated. If not, press the AUTO START/ STOP toggle key to
place the unit in Start/Stop mode. The AUTO START/STOP indicator will then be illuminated.
The AUTO START/STOP key is used to change the operating mode from Continuous Run to Auto Start/Stop. Each
push of the key will alternate the operating modes. The Auto Start/Stop indicator on the display will illuminate when
Auto Stop/Start is enabled. If the indicator is not illuminated, the unit is in the Continuous Run Mode.
Auto Start/Stop is provided to permit starting/restarting of the diesel-driven compressor as required. This gives the
microprocessor automatic control of starting and stopping the diesel engine. The main function of auto start-stop is
to turn off the refrigeration system near set point to provide a fuel efficient temperature control system and then
restart the engine when needed.
