CS-SA9CKP CU-SA9CKP5 / CS-SA12CKP CU-SA12CKP5

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
(Only for CU-SA9CKP5)
Once the compressor is activated,it does not
stop for 60 seconds.It stops immediately with
remote controller ON/OFF button.
Anti-freezing operation for outdoor unit(during
Heating Mode Operation only)
Temperature of the condenser is tested by TRS.
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.
If the outdoor fan does not run after the
compressor is activated for 50sec,the
compressor will stop.(only in cooling
and soft dry mode oteration)
If the unit is stopped during Heating
Operation,the 4-way valve will remain in
heating mode operation mode for 5 minutes.

7 Operation Details
7.1. Cooling Mode Operation
•
• •
• When selecting the Cooling Mode Operation, the unit will operate according to the setting by the Remote Controller 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 controller, Compressor Protection Control will be reset.
•
• •
• 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 or below for 2 minutes, the compressor is ceased for 3 minutes then restarts. (Time
Delay Protection Control is effective.)

7.2. Soft Dry Mode Operation
•
• •
• When selecting Soft Dry mode operation, the operation will be cooling untill the room temperature reaches the set temp on the
remote control, and then Soft Dry will be actived. (During Soft Dry Mode the fan of indoor unit will operate at super low speed.)
•
• •
• Once soft Dry mode operation is turned off, indoor fan, compressor and outdoor fan will stop for 6 minutes.
•
• •
• During cooling mode operation, if the compressor ceased, it will not restart within 3 minutes.
•
• •
• Same as the denotation in Cooling Operation. (P.14)
(During Soft Dry Mode Operation, compressor will stop for at least 6 min.)
•
• •
• Same as the denotation in Cooling Operation. (P.14)
•
• •
• Same as the denotation in Cooling Operation. (P.14)
During Soft Dry Operation, use remote controller to select Auto Fan Speed mode.
•
• •
• Indoor Fan Speed is at super low.
•
• •
• Deodorization control.

Warm booting control
•
• •
• When turning on the unit by heating mode operation, indoor
fan will be activated when temperature of indoor heat
exchanger reaches 30°C.
•
• •
• Warm boot operation ends when temperature of indoor
heat exchanger reaches 34 °C.
•
• •
• During warm booting or within 3 minutes after the ending
the Ry-C will not turn off.
7.3. Heating Mode Operation
When selecting heating mode operation, the unit will operate according to the setting by the remote controller.
•
• •
• If the compressor stopped by switching off,turning off by remote controller, or power off, it will not restart within 3 minutes.
•
• •
• When room temperature reaches the set temperature on the remote controller, compressor stops and will not restart within 4
minutes.
•
• •
• 3 minutes after the compressor stopped, indoor fan will stop for 1 minute. Then indoor fan will resume operation with the speed
at "super low".
•
• •
• When temperature of indoor heat exchanger rises to 51°C, outdoor fan will stop when temperature of indoor heat exchanger
falls to 49°C, outdoor fan will restart.
•
• •
• When temperature of indoor heat exchanger rises to 65°C or above, compressor stops, and will restart 4 minutes later.
•
• •
• Same as the denotation in Cooling Operation.(P.14)
•
• •
• If the compressor has been running for 5 minutes, but the difference of temperature between intake air and indoor heat
exchanger is continuously lower than 5°C or below for 2 minutes, compressor will stop and resume operation in 4 minutes.
•
• •
• During heating mode operation, 4-way valve is at "open" mode.
•
• •
• During heating mode operation, if the unit turned off , the 4-way valve will remain at "open" mode for 5 minutes.

Automatic Fan mode operation
Time graph for heating mode operation
When selecting automatic fan mode by remote controller during heating mode operation, the fan will operate at different speed
under different conditiors according to the temperature of indoor heat exchanger.

CS-SA9CKP CU-SA9CKP5 / CS-SA12CKP CU-SA12CKP5

Deice Control
Deice operation is to protect the outdoor unit from freezing.
•
• •
• Normal Deice Operation
Decing starts 30 minutes after heating mode operation or 60 minutes after the latest decing operation. If temperature of
outdoor piping, tested by TRS, falls to 3°C (TRS OFF)or below for continuously 50 seconds, deicing operation starts.
•
• •
• Overload Deicing Operation
During heating operation, if the accumulative stopping time of outdoor fan reaches 60 minutes, deicing operation will start
1 minute after compressor starts.
•
• •
• Deicing operation ends under conditions below
1. After 12 minutes.
2. Temperature of outdoor unit rises to 4°C.
3. Because of time delay (Td), deicing operation will not end immediately.
•
• •
• Once deicing starts, it will not end within 60 seconds.
•
• •
• When deicing operation ends, compressor will stop for 30 seconds, and 4-way valve remains at cooling mode operation for
10 seconds.
