Repair IOL circuit.

Open service valve fully.

Repair outdoor PMV.

Set normal wiring.

Are gas pipe, liquid pipe,

and service valve of the outdoor unit

fully open?

Is wiring correct?

Insufficient refrigerant,

blockage, pipe breakage

(Check miswiring of the outdoor unit according to miswiring check function.)

Check there is no blockage or pipe breakage, and then add
refrigerant according to judgment of refrigerant amount.

Is IOL circuit normal?
1. Connector
2. Wiring
3. Outdoor P.C. board

Are outdoor PMV A
and PMV B normal?

1. Connector connection
2. Wiring 3. Coil
4. Valve unit
5. Outdoor P.C. board

Check code

Operation cause

[E5]

Inverter IOL operation

1. Inverter IOL operation

2. Service valve closed

3. Outdoor PMV A error or cooling bypass PMV B error

4. Miswiring of communication between indoor and outdoor unit
