Rearrange the piping to
avoid contact with the
casing.
Noise/vibration is
generated when the
refrigerant gas or liquid
flows through inside of
piping of air-conditioner.
It is likely to occur
particularly during cooling
or defrosting in the heating
mode. It is normal.
The noise/vibration occurs
when the refrigerant starts
or stops flowing. It is
normal.
When the defrosting starts
or stops during heating
mode, the refrigerant
flow is reversed due to
switching 4-way valve.
This causes a large change
in pressure wich produces
a blowing sound. It may
also accompany the hissing
sound as mentioned above.
This is normal.
After the start or stop of
heating operation or during
defrosting, abrupt changes
in temperature cause resin
parts to shrink or expand.
This is normal.
It is the sound produced
by the drain pump that
discharges drain from
indoor unit.
The pump continues to run
for 5 minutes after stopping
the cooling operation.
This is normal.
Apply the damper sealant
at the place considered
to be the sources such
as the pressure reducing
mechanism (Expansion
valve, capillary tube, etc.)
