2) Only Indoor blowers do not work

WHAT TROUBLED COMPLAINTS HOW TO CHECK REMEDY

Other parts except theunit

Magnetic switch forcompressor & fan motor

Operating switch

• 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.

Check it with the eyes ortester.

• Repair a switch boxand relative instrument.

• Replacement of fuse

• Request a power supplier to repair.

Check the power source.Use a thick cable ifnecessary.

Replace it if necessary.

Repair or replace it.

Note: Use an appropriate measuring instrument for readjustment.

*1: High-pressure switch moves.

*2: Low- pressure switch moves.

2. The Units discontinue after the operation started


Outdoor coil

In-condensable gasblended.

High pressure switch(Option part)

Refrigerant

Outdoor Fan

Coil is dirty *1

Air intruded into the refrigerant pipe line *1

Improper adjustment

A shortage of refrigerantamount. * 2

Check pressure

Reverse rotation of fan Obstacle

Air short circuit *1

Checking

In the event that difference between thesaturating temperaturecorresponding to highpressure and the temperature of air discharged from the outdoor 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 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.
