When the temperature of evaporator
reaches 51 C,outdoor fan stops,and will
restart when the temperature of evaporator
declines to 49 C.
When the temperature of evaporator
reaches 65 C,compressor will stop.
(For PA7CKE/PA9CKE/PA12CKE only)
Outdoor Unit
To protect the compressor from reverse
rotation when power off suddenly.
The 2-step Overload Protector is to protect
the compressor when
1/ temperature of compressor reaches 120 C
2/ high temperature or current enters into the
compressor. (for PA7CKE, PC7CKE,
PA9CKE, PC9CKE only)
Once the compressor is activated,it does not
stop for 60 seconds.It stops immediately with
remote controller ON/OFF button.

•
If temperature of evaporator is lower than 2°C continuously
for 4 minutes, the compressor will cease to prevent the
evaporator from freezing. Fan speed setting will not be
changed.
•
When temperature of evaporator reaches 10°C,
compressor will restart.
During Cooling Mode Operation, the Time Delay Safety Control
is available.

•
When selecting the Cooling Mode Operation, the unit will operate according to the setting by the Remote Control and the
operation is as the following.
•
3 min. ---- The compressor is ceased for 3 minutes to balance the pressure in the refrigeration cycle.
•
(Protection of compressor).
•
7 min. ---- The unit will automatically operate in 7 minutes even if the room temperature is not reached.
(Prevention of raising the humidity)
•
If the outdoor fan motor does not run 50 seconds after the compressor starts, the compressor will cease and restart in 3
minutes.(Time Delay Safety Control is effective.)
•
If this symptom occurs repeatedly 3 times, the compressor will stop.
•
If the operation mode changed or the unit turned off by remote control, Compressor Protection Control will be reset
(for PA7CKE, PA9CKE, PA12CKE only).
•
If the compressor has been continuously running for 5 minutes, and the difference of temperature between intake air and
evaporator is continuously lower than 2.5°C for 2 minutes, the compressor is ceased for 3 minutes then restarts. (Time Delay
Protection Control is effective.)
