Warranty Information
Refer to the service manual for basic features, operation, and servicing.
- The unit has two main operation modes: cargo cooling control mode and unit inspection mode.
- The cargo cooling control mode includes Frozen mode, Chilled mode, and Defrosting mode.
- Frozen mode: Compressor ON/OFF control based on return air temperature.
- Chilled mode: Capacity control with suction modulating valve and hot-gas bypass control.
- Defrosting mode: Hot-gas defrosting with refrigerant metering control.
