11 Refrigerant leak
Check inside of the unit on refrigerant leakage.
If there is a refrigerant leak, try to repair the leak.
If the repair is unsuccessful, call your local dealer.
Do not touch any refrigerant which has leaked out
from refrigerant piping connections. This may result
in frostbite.
12 Oil leak
Check the compressor for oil leakage. If there is an
oil leak, try to repair the leak. If the repairing is
unsuccessful, call your local dealer.
13 Air inlet/outlet
Check that the air inlet and outlet of the unit is not
obstructed by paper sheets, cardboard, or any
other material.
14 Record the contents of field setting.
Record them on the accessory REQUEST FOR
THE INDICATION label.
And attach the label on the back side of the front
panel.
15 Record the installation date.
Record the installation date on the accessory
REQUEST FOR THE INDICATION label.
And attach the label on the back side of the front
panel.
CAUTION
Do not insert fingers, rods or other objects into
the air inlet or outlet. When the fan is rotating at
high speed, it will cause injury.
CAUTION
Do not perform the test operation while
working on the outdoor units (multi system)
and the indoor units.
When performing the test operation, not only the
outdoor unit, but the connected indoor unit will
operate as well.
Working on an indoor unit while performing a
test operation is dangerous.
CAUTION
During tests never pressurize the appliances
•
with a pressure higher than the maximum
allowable pressure (as indicated on the
nameplate of the unit).
If refrigerant gas leaks, ventilate the area
•
immediately.
Toxic gas may be produced if refrigerant gas
comes into contact with fire.
Never directly touch any accidental leaking
•
refrigerant.
This could result in severe wounds caused by
frostbite.

DANGER: DO NOT TOUCH PIPING
AND INTERNAL PARTS.
See "2. General safety precautions".
DANGER: ELECTRICAL SHOCK
See "2. General safety precautions".
INFORMATION
Note that during the first running period of the
unit, required power input may be higher.
This phenomenon originates from the
compressor that requires a 50 hour run elapse
before reaching smooth operation and stable
power consumption. Reason is that the scroll is
made out of iron and that it takes some time to
smooth the surfaces that make contact.
16.1.2 Test operation
The procedure below describes the test operation of
the complete system. This operation checks and judges
following items:
Check of wrong wiring (communication check with
•
indoor units).
Check of the stop valves opening.
•
Judgment of piping length.
•
On top of this system test operation, indoor units
operation should also be checked separately.
Make sure to carry out the system test operation
•
after the first installation. Otherwise, the malfunction
code u3 will be displayed on the user interface and
normal operation or individual indoor unit test run
cannot be carried out.
Abnormalities on indoor units cannot be checked for
•
each unit separately. After the test operation is
finished, check the indoor units one by one by
performing a normal operation using the user
interface. Refer to the indoor unit installation manual
for more details concerning the individual test run.
INFORMATION
It may take 10 minutes to achieve a uniform
•
refrigerant state before the compressor starts.
During the test operation, the refrigerant
•
running sound or the magnetic sound of a
solenoid valve may become loud and the
display indication may change.
These are not malfunctions.
Procedure
1 Close all front panels in order to not let it be the
cause of misjudgment.
2 Make sure all field settings you want are set.
3 Turn ON the power to the outdoor unit and the
connected indoor units.
