Criteria
1
High and low pressure values
are normal.
Check it with a pres-
sure gauge.
Cooling: low pressure
approx. 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.
