Test operation
The procedure below describes the test operation of the complete
system. This operation checks and judges following items:
■
Check of the stop valves opening
■
Check of wrong wiring
■
Check of refrigerant overcharge
■
Check of indoor unit operation
On top of this test operation, the indoor unit operation can also be
checked separately. Refer to the indoor unit installation manual for
more details.
■
Make sure to carry out the test operation after the first
installation. Otherwise, the malfunction code
U3
will be displayed
on the remote controller and normal operation can not be carried
out.
■
Abnormalities on indoor units can not 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
remote controller.
1
Close all front panels except the front panel of the electric
component box.
2
Turn ON the power to the outdoor unit and the connected indoor
units.
Be sure to turn on the power 6 hours before operation in order to
have power running to the crankcase heater and to protect the
compressor.
3
Push
BS4 TEST
button for 5 seconds or more. The unit will start
test operation.
■
The test operation is automatically carried out in heating
mode, the H2P LED will blink and the messages "Test
operation" and "Under centralized control" will display on the
remote controller.
■
It may take 10 minutes to bring the state of the refrigerant
uniform 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 LED display may change, but these are not mal-
functions.
■
During the test operation, it is not possible to stop the unit
operation from a remote controller. To abort the operation,
press the
BS3 RETURN
button. The unit will stop after
±30 seconds.
Test run may take up to 1 hour or more.
4
Close the front panel in order to let it not be the cause of
misjudgement.
5
Check the test operation results by the LED display on the
outdoor unit.
6
When the test operation is fully completed, normal operation will
be possible after 5 minutes.
Otherwise, refer to
"Correcting after abnormal completion of the
to take actions for correcting the
abnormality.
WARNING
■
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.
■
Test run is possible for ambient temperatures between
–20°C and 35°C.
DANGER: DO NOT TOUCH PIPING AND INTERNAL
PARTS

DANGER: ELECTRICAL SHOCK

NOTE
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.
NOTE
To protect the compressor, be sure to turn on the
power supply 6 hours before starting operation.
