OUTDOOR UNIT Error Method:
Low Pressure Error

Indicate or Display:

Outdoor Unit : LED1 Flash, LED2

8 Times Blink

Indoor Unit : Operation LED Flash

Timer LED 3 Times Blink

Swing LED 3 Times Blink

ERROR CODE : E : 32

Detective Actuators:

Outdoor Unit Controller PCB circuit

Suction Pressure Sensor

Detective details:

Low pressure is continued 0.1Mpa or less for 10 minutes and detects it 5 times

within 180 minutes.

(Low pressure is continued 0.1Mpa or less for 2 minutes in test run)

Check Point 1 : Check if Gas Pipe Valve is open

If it is not open, open it and check the operation.

Check Point 4 : Check Solenoid Valve

Check Solenoid Valve (SV1)

(PARTS INFORMATION 8)

>>If Solenoid Valve is defective, replace it.

Check Point 3 : Check Indoor Unit Operation

Is Indoor Unit EEV open?

(PARTS INFORMATION 5)

Check if Indoor Heat Exchanger is clogged or dirty filter.

Stop the operation and rotate the fan by hand.

(Check if FAN and Bearing is hooked, removed or Locked Motor.)

>>If Fan or Bearing is abnormal, replace it.

Check Fan Motor of Indoor Unit

(PARTS INFORMATION 10,11)

>>If Fan Motor is defective, replace it.

Check Point 2 : Check Gas Leak or Less Gas

Measure Gas pressure, if there is a leak, correct it.

>>If recharging refrigerant, make sure to perform vacuuming

and recharge the specified amount.

MPa MPa

Forecast of Cause :

1. Gas Pipe Valve is close 2. Gas Leak, less 3. Indoor Unit failure 4. Solenoid Valve failure

06-31

Check Point 4 : Check Outdoor FAN, Heat Exchanger

Is there anything obstructing the air distribution circuit?

Is there any clogging of Outdoor Heat Exchanger?

Is the Fan rotating?

(Check by hand and if it is locked, replace the motor)

Check Outdoor Fan Motor

(PARTS INFORMATION 12)

>>If the Fan Motor is defective, replace it.
>>If defrost operation is abnormal, check the thermistor(TH4)

Is Liquid side Strainer open?

(PARTS INFORMATION 5)

>>If Strainer is defective, replace it.

(PARTS INFORMATION 6)

Is Solenoid Valve (SV4 of Slave Unit) open?

(PARTS INFORMATION 9)

Check Point 2 : Check if EEV1, SV4 is open

Is EEV (EEV1) open?

If the service tool is connected, check if there is an

indoor unit that is extremely low heat exchanger

temperature.

(On heating, the refrigerant flows to the stopped

indoor unit as well.)

< Cooling mode >

Check Point 1 : Check if Liquid Valve is open

If it is not open, open it and check the operation.

< Heating mode >

Check Point 3 : Check Gas Leak or Less Gas

Measure Gas pressure, if there is a leak, correct it.

>>If recharging refrigerant, make sure to perform vacuuming

and recharge the specified amount.
