Ineffective Cooling or Heating
Check of outdoor coil
(heat exchanger) & the fan
operation.
Check gas leakage.
Repair gas leak.
Replacement of unit if the
unit is beyond repair.

Check heat load increase in
cooling operation.
Unexpected residue
Added electrical utencil
Check of inside gas
pressure.
Adjust refrigerant
charge.
Malfunction of compressor.
Replacement of
compressor
Check of cold (warm) air cir-
culation for smooth flow.

(heat exchanger.)
Malfunction of fan.
Clogging of air filter.
Obstruction at air outlet.
Countermeasure against
above 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 Air
Conditioning caused by a defect in the refrigeration circuit and improper application.
Unit runs but ineffective cooling

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
WHAT TROUBLED COMPLAINTS HOW TO CHECK REMEDY
Outdoor coil
In-condensable gas
blended.
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 refrigerant
amount. * 2 Check pressure

Obstacle
Air short circuit *1
Checking
In the event that
difference between the
saturating temperature
corresponding to high
pressure and the
temperature of air
discharged from the
outdoor coil is more than
15°C, incondensable gas
may be blended.
Check it with a pressure
gauge.
Confirm the wind blowing
out upward.
Check it with eyes.
Wash it by means of
something like chemical
washing.
Extract air by vacuum
pump, then replenish
(charge) the refrigerant.
Read just it to normal
operating pressure.
(Note)
Don't alternate the
specified adjusting
pressure. If the adjusted
pressure exceed the
specified range, it will
cause a great accident.
Replenish the
refrigerant. Repair the
spot where it is leaked.
If reversed, connect
interchanged wires to
each terminal.
Power wirings.
