Troubleshooting Guide

— 7 —

Ineffective Cooling or Heating

Check of outdoor coil(heat exchanger) & the fanoperation.

Check gas leakage.

Repair gas leak.

Replacement of unit if theunit is beyond repair.

Satisfactory operation withtemperature difference ofinlet & outlet air ;COOLING : 7~10°CHEATING : 15~17°C

Check heat load increase incooling operation.

Unexpected residue

Added electrical utencil

Check of inside gaspressure.

Adjust refrigerantcharge.

Malfunction of compressor.

Replacement ofcompressor

Check of cold (warm) air cir-culation for smooth flow.

Dirty indoor coil(heat exchanger.)

Malfunction of fan.

Clogging of air filter.

Obstruction at air outlet.

Countermeasure againstabove trouble.

Check clogging in refrigera-tion circuit.

Repair clogging in refrigera-tion circuit.

In general, possible trouble is classified in two causes.The one is called Starting Failure which is caused from an electrical defect, and the other is Ineffective AirConditioning caused by a defect in the refrigeration circuit and improper application.

Unit runs but ineffective cooling

— 8 —


Fails to Start

Check of circuit breakerand fuse.

Check control switch.

Fan only fails to start.

Improper wiring.

Defect of fan motorcapacitor.Defect of compressor

capacitor.

Irregular motor resistance( Ω )Irregular motor insulation( Ω )

Replacement of fan motor.

Improper electric heater

Replacement of electric heater.

Regular but fails to start.

Replacement of compressor.

Electric heater is not energized

Loose terminal connection.

Improper wiring

Irregular motor resistance ( Ω )

Irregular motor insulation ( Ω )

Replacement of compressor

Drop of power voltage.

Capacitor check.

Replacement of capacitor.

Compressor only fails to start.

Check power source.

Check control switchsetting.

PACKAGE AIR CONDITIONER VOLTAGE LIMITS

1. No cooling and heating operation performed1) Both the blower and the compressor do not work

NAME PLATE RATING MINIMUM MAXIMUM

380/415 V 323 V 477 V

2) Only Indoor blowers do not work

WHAT TROUBLED COMPLAINTS HOW TO CHECK REMEDY

Other parts except theunit

Magnetic switch for com-pressor & fan motor

Operating switch

• Electric supply interrupted• Defective power wiring• Cut off power fuse

Too low voltage

Control point is on condi-tion of "OFF" due to trou-ble.

Troubled or defectivecontactor

Measure power sypplywith a tester in case thatthe same power source issupplied to other equip-ment 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 box andrelative instrument.

• Replacement of fuse

• Request a power supplier to repair.

Check the power source.Use a thick cable if nec-essary.

Replace it if necessary.

Repair or replace it.

Check how it is insulated.



Rewiring or repair.

4) Only compressor does not work


Magnetic switch forcompressor motor

Compressor motor

High pressure switch(Option part)

Electric circuit

Defective contact, magnetic coil troubled.

Troubled over-heated (layer short)

Troubled or defective contact or operating

Defective connection ordisconnection of the circuitfor compressor.

Check it with the eyes onwith a tester.

Check how it is insulated.




Replace or repair thecompressor.

Replace it if neces-sary.

Rewiring or push resetbutton.

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.
