Check method

Criteria

High and low pressure
values are normal.

Check it with a
pressure gauge.

Cooling: low pressure ap-
prox. 0.8 MPa
Heating: high pressure ap-
prox. 3.0 MPa

Drain water is dis-
charged smoothly
through the drain hose.

Check it by pour-
ing water.

―

Indoor and outdoor unit
fans are operating.

Check them visu-
ally.

―

Compressor operates after
the indoor unit operates.

Check the operat-
ing sound.

―

Difference between inlet
and outlet temperatures
is normal.

Measure the inlet
and outlet temper-
atures.

Temperature difference 10
degrees

Error is not displayed

Check the 7
