OPERATION

Pre-run checks

■

Be sure to perform a test run.

■

Be sure to fully open the liquid-side and gas-side stop valves. If
you operate the unit with stop valves closed, the compressor will
break down.

■

Be sure to execute the ﬁrst test run of the installation in cooling
mode operation.

■

Never leave the unit unattended with an open front panel during
test run.

Test run

Be sure to turn power on at least 6 hours before starting
operation in order to protect the compressor.

Make sure the liquid and gas stop valves are open.

Be sure to close the frontside panel before operation, as not
doing so can cause electric shock.

Be sure to set the unit to cooling operation mode.

Press the inspection/test operation button of the remote
controller 4 times (2 times in case of a wireless remote
controller) to go into the test run mode.

Press the ON/OFF button within 10 seconds to start the test run
and check the operation status for about 6 minutes. The
refrigerant pressure may not rise immediately, even if the stop
valve is opened after an air purge is performed using a vacuum
pump. This is because the indoor unit refrigerant piping is closed
off with electric valves inside. This will not create any problems
during operation.

Push the air ﬂow direction adjust button and check if the unit is
responding to the new air ﬂow direction position.

Press the inspection/test operation button of the remote
controller 2 times to go into check mode and to make sure that
the malfunction code displays

(=normal). In case the

malfunction code does not display

, refer to

"Failure

diagnosis at the moment of ﬁrst installation" on page 13

If the inspection/test operation button is pressed 4 times during a
test run, the unit returns to normal operation.

Check all functions according to the operation manual.

NOTE

The earth leakage breaker must be a high-speed type
breaker of 30 mA (<0.1 s).

(1) European/International Technical Standard setting the limits for harmonic

currents produced by equipment connected to public low-voltage systems
with input current >16 A and

≤

75 A per phase.

WARNING

Live parts can be easily touched by accident.

Never leave the unit unattended during installation or
servicing when the service panel is removed.

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-in period before reaching smooth operation and
stable power consumption.

Items to check

Electrical wiring
Inter-unit wiring
Ground wire

■

Is the wiring as mentioned on the wiring
diagram?
Make sure no wiring has been forgotten and that
there are no missing phases or reverse phases.

■

Is the unit properly grounded?

■

Is the wiring between units connected in series
correct?

■

Are any of the wiring attachment screws loose?

■

Is the insulation resistance at least 1 M
