009 F809 ・ E809
Alarm
Logic
F809 E809 is generated twice (Refrigerant shortage)
E809 Refrigerant shortage
Chilled mode
＜Full Cool＞ EEV Opening≧400 pls, and RS is not drop 0.2℃ for 1 hour
＜Modulation＞ EEV Opening≧400 pls continuously for 5 minutes
Frozen
＜RS≧0℃＞ EEV Opening≧400 pls, and RS is not drop 0.2℃ for 1 hour
＜RS＜0℃＞ EEV Opening≧400 pls continuously for 5 minutes
Possible
Causes
＊Shortage of refrigerant
＊Liquid line (dryer) is clogging
＊EEV failure
Trouble
Shooting
Step 1. LSV check
Step 2. Liquid line check and dryer
blockage check
Step 3. EEV check
Step 4. Check refrigerant shortage
If there is no problem in above items, it seems to be refrigerant shortage.
Conduct refrigerant recovery and charge specified amount of refrigerant after checking
location of refrigerant leakages.
Controller
Action
F809 Unit stop
E809 Restart after 3 minutes
Refer to
002
for the troubleshooting.
The causes of
009
seems to be the same as
002
and
011
. Among them, it may be insufficient refrigerant.
