outdoor unit stops before
reaching set up temp.
check the plug inserted into the outlet and the power supply
if the battery is dead or failure in remote controller
change to new one
check the fuse by eyes or cheak the electric continuity by tester
check the resistance by tester [see fig.1]
other than described above [how to operate
emergency operation test operation]

FLASHING OFF OFF
FLASHING ON ON
check the resistance by tester [see table 1]
check the resistance by tester [see table 2]
check the resistance between two terminals [see fig.2,table 3]
check the voltage between blue's connection and yellow one. [see fig.3]
adjust proper temperature in remote controller
check the resistance by tester [see table 2]
check the restarting operation of compressor, after passing 3 minute
check the resistance of sensor (temp. heat exchanger)
[see table 1]
check proper voltage of power supply and use an exclusive power supply
check proper voltage of power supply and use an exclusive power supply
check by eyes
check the pressure of gas [check

if the scale of the tester swings instantly to "zero Ω " and does not
move back to "infinity", capacitor for compressor should be replaced
[NOTE.2]
other than described above
leak of gas, or cut off of overheat prevention relay
check the wiring order
change PCB(main controller)
other than described above
check by eyes and clean it
check the resistance by tester [see table 2]
check the resistance by tester [see table 1]
check the blockage of air outlet of TAN
check the blockage of air inlet & air outlet of TAG
check the pressure of gas [check

other than described above
check the pressure of gas [check 「 performance curve diagram 」 ]
check the blockage of air inlet & air outlet of TAG
check by eyes after power off. turn by hands and check noise
check by eyes around the pipes with any obstacles
level louver position
check the pressure of gas [check 「 performance curve diagram 」 ]
check the level of TAN
check the drain pipe is stopped up
if DC5V is achieved between black and brown lead wiring of fan motor,
while no voltage of pulse between white and black wiring, then TAN fan
motor should be replaced
check the voltage between 2 and 3 in terminal [see fig. 6]
check the wiring of 3 and 4 in terminal
(not turning TAG fan)
other than described above
check the wiring order(NO ROTAION)
if the scale of the tester swings instantly to "zero
Ω
" and does
not move back to "infinity", capacitor for TAG fan motor should
be replaced [NOTE.2]
other than described above
check the voltage between 2 and 4 in terminals [see fig.5]
