Defrosting operation is controlled by the temperature of outdoor heat exchanger sensed by the thermistor and•
the timer switch.
Defrosting operation starts when the both of the following conditions are met at the same time.•
a)35 minutes’of continuous run of the compressor after the start of heating operation or after the completion of
previous defrosting operation.
b)The temperature of the outdoor heat exchanger stays lower than -1.5°C continuously for two minutes.
Defrosting operating is called o if either of the following conditions is met.•
a)The temperature of outdoor heat exchanger rises to 19°C while 4-way-valve is ON.
b)12 minutes has passed since compressor turned ON.

TROUBLESHOOTING GUIDE
FOR YOUR SAFETY USE
For the safety and proper use and handling of the product, please read and follow the instructions carefully.•
The meaning of the marks below are as follows.•
Never remodel appliance.•
Use designated parts or accessories to avoid accidents.
In case of gas leakage, not only rell the required amount of the refrigerant gas but also•
nd out the gas leakage point and mend it. If the service work has to be suspended
before mending the leakage points, be sure to collect the refrigerant gas in the unit by
using pump then fasten the service ports to avoid any further leakage. Poisonous gas
may be generated when the leaked refrigerant is exposed to re.
Be sure to change the cable if it is damaged.•
Do not use damaged cable.
Do not use power supply cord extended or connected in halfway.•
Be sure to put the units to earthing works.•
Be sure to check the insulated resistance, more than 1M Ω.•
Warning
Check
Point
Check
Point
If leakage of refrigerant occur in the installation, ventilate a room.•
If the leaked refrigerant is exposed re, poisonous gas may be generated.
Danger
Boosting capacitor make the control box assembly high voltage.•
Make the capacitor discharge enough when servicing. Otherwise will be struck by elec-
tricity.
Improper use will cause the signicant risk of death or serious injury of the user.
Improper use may cause the risk of death or serious injury of the user.

DISPLAY OF ERRORS IN THE PAST
For a unit display board•
Press and hold the PUMP SW. and RESET SW. at the same time for 5 seconds to display a past error code and its
sequence number.
The PUMP SW. can then be used to select between a maximum of 8 past error codes to display. (If there are no er-
ror codes, “ - - ” is displayed.)
1. Display method
2. Display cancellation
For a unit display board•
While an error code is being displayed, press and hold the PUMP SW. and RESET SW. at the same time for 5 sec-
onds to cancel the error code display and turn o the display.
Alternatively, if no operations are performed for 5 minutes, the error code display is automatically cancelled and
the display turned o.
While an error code is being displayed, press and hold the reset switch for 10 seconds or more to delete all past
error codes. The display turns to “ - - ”.
