Check description Check method Criteria
1
High and low pressure values
are normal.
Check it with a pres-
sure gauge.
Cooling: low pressure ap-
prox. 0.8 MPa
Heating: high pressure
approx.
3.0 MPa
2
Drain water is discharged
smoothly through the drain
hose.
Check it by pouring
water.
―
3
Indoor and outdoor unit fans
are operating.
Check them visually. ―
4
Compressor operates after the
indoor unit operates.
Check the operating
sound.
―
5
Difference between inlet and
outlet temperatures is normal.
Measure the inlet and
outlet temperatures.
Temperature difference
10 degrees
