Excess charge of refrigerant
∗
Air intrudes into refrigerant

∗
Flushing noise due to
refrigerant shortage.
(Sound of shoo...)
Does
the noise
generate with vibration
of unit mounting
section?
Does
the noise generate
with vibration of whole
ceilings and
walls?
Is the piping secured?
Does
the fan contact with other
parts?
Does
the pipe contact with
casing?
Is the
noise flushing
sound from pressure
reducing valve or
capillary
tube?
Correction of installation
Reinforcement for ceilings or
walls
Insert shock absorber in
mounting section, or strengthen
the mounting section.
Normal. The sound is flushing
noise of gas (refrigerant) inside
air conditioning unit
Insert cushion materials to the

Normal. The noise is a sound
generated at the time of gas
(refrigerant) flow change or stop
Disassemble and remove parts
contact.
Normal. Operation sound of
draining device
Correct piping manually or
attach a dead weight to pipe
Normal. Creak generates by
shrinkage of resin parts due to
