Electric supply interrupted Defective power wiring Cut off power fuse

Too low voltage

Control point is oncondition of "OFF" due totrouble.

Troubled or defectivecontactor

Measure power sypplywith a tester in case thatthe same power source issupplied to otherequipment except the unit,what and where troubledcan be discovered bychecking the operation ofother equipment.

Measure it with a tester.

Make short-circuit, thenmeasure it with tester.

Checking

In the event that difference between thesaturating temperaturecorresponding to highpressure and the temperature of air discharged from the outdoor coil is more than15C, incondensable gasmay be blended.

Check it with a pressuregauge.

Confirm the wind blowingout upward.Check it with eyes.

Wash it by means ofsomething like chemicalwashing.

Extract air by vacuumpump, then replenish(charge) the refrigerant.

Read just it to normaloperating pressure. (Note)Don't alternate the specified adjusting pressure. If the adjustedpressure exceed thespecified range, it willcause a great accident.

Replenish the refrigerant. Repair thespot where it is leaked.

If reversed, connectinterchanged wires toeach terminal. Power wirings.
