Warranty Information
No specific warranty period is mentioned in this manual.
The unit has several operation modes: 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, based on supply air temperature.
Defrosting mode: Hot-gas defrosting with refrigerant metering control.
The unit also supports dehumidification control via a reheat coil, adjustable from 60-95%RH. Mode operation allows for generator setting, automatic pump down, and dehumidification mode setting.
Troubleshooting and error codes
| Alarm grouping | Alarm code | Alarm content | Action with alarm | |
| Permanent stop | F101 | HPS activated within 30 seconds after operation start or protection device activated 5 times at start-up operation or Fuse 1 brown (Refer Page 7-7). | Unit stops | |
| F109 | Low- pressure drops to–85kPa or lower within 2 seconds after operation start. | Unit stops | ||
| F111 | HPS does not activate when it reaches to the set value. | Unit stops | ||
| F301 | Temperature setting required (SRAM failure) | Unit stops | ||
| F401 | Return / Supply for data / Supply air sensor malfunction (at chilled mode) | Unit stops | ||
| F603 | Suction modulating valve (SMV) does not fully close contrary to the designation or initial setting of the controller is wrong. | Unit stops | ||
| Protection device activation | F701 | Abnormal high voltage (over 600V) or low voltage (under 300V) | Unit stops | |
| F705 | S phase became open phase | Unit stops | ||
| F803 | Abnormalities, which make it impossible to continue operation (Note2.) | Unit stops | ||
| Control error | E101 | High-pressure switch activated during normal operation. | Restart after 3-minute | |
| E103 | CTP or electronic OC activated during normal operation. | Restart after 3-minute | ||
| E105 | Micro processor OC activated during normal operation. | Restart after 3-minute | ||
| E107 | DCHS became abnormal high temperature during operation. | Restart after 3-minute | ||
| E109 | In the event the refrigerant circulation rate is low, the unit error will be detected to stop the unit. Low pressure drops to-90kPa or lower for 2 seconds or longer successively during normal operaton. | If this error occurs two times, F803 will stand by for three minutes to restart then. Restart after 3-minute | ||
| E201 | Pump down is not completed within 90 seconds. | Only alarm display | ||
| E203 | Overcool protection activates in the chilled. (Control temperature ≤ SP-3°C or for 3 minutes) | Restart after 3-minutes | ||
| E205 | Evaporator for motor failure (Note 2) | Only alarm display | ||
| E207 | Defrosting is not completed within 90 minutes | Only alarm display | ||
| E303 | Humidity setting required (SRAM failure) | Only alarm display | ||
| E305 | Defrost timer setting required (SRAM failure) | Only alarm display | ||
