9.3. Checklist
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
(6) Error is not displayed.
Check the 7-segment
display.
Error blinking or no error
