Checking

In the event thatdifference between thesaturating temperaturecorresponding to highpressure and thetemperature of airdischarged from theoutdoor coil is more than15°C, 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 thespecified adjustingpressure. If the adjustedpressure exceed thespecified range, it willcause a great accident.

Replenish therefrigerant. Repair thespot where it is leaked.

If reversed, connectinterchanged wires toeach terminal.Power wirings.
