COMMISSIONING
2 if the insulation resistance is below 1 MΩ, disconnect the
compressor cable on the inverter PCB. Then switch on the
main power supply to apply current to the crankcase heating
elements. Once current has been received for more than 3
hours, re-measure the insulation resistance. (Current may
be required for longer, depending on the air conditions,
the pipe length or the condition of the refrigerant) Check
the insulation resistance and re-connect the compressor.
Where the earth leakage breaker is tripped, check the
recommended size: see in chapter
main breaker switch".
11.2 CARRY OUT THE TEST RUN
• Check that the stop valves on the outdoor unit are fully open
(gas, low-pressure: only in heat recovery systems) and start
the system. (Where base units are combined, check that the
stop valves on all outdoor units connected are fully open).
• Carry out the test run on the indoor units in sequence, one
by one. Then check the concordance of the refrigerant pipe
system and the electrical wiring system. (System conformity
cannot be checked if there are several indoor units operating
at the same time.)
11.3 TEST RUN PROCEDURE BY REMOTE CONTROL SWITCH (PC-ARFPE EXAMPLE)
1 Turn ON the power supply for all the indoor units.
2 For the models with the auto-address function, wait for 3
minutes approximately. The addressing is automatically
performed. (There is a case that 5 minutes is required according
to the setting condition.) After that, select using language from
"Menu". Refer to the operation manual for details.
3 Press and hold " " (menu) and " " (return) simultaneously for
at least 3 seconds.
a. The test run menu will be displayed.
b. Select "Test Run" and press "OK". The test run settings will
be displayed.

When "00" is indicated, the auto-address function may be performing.
Cancel "Test Run" mode and set it again.

• Make sure the electric components in the installation (earth leakage
breaker, circuit breaker, cables, connectors and cable terminals) have
been selected correctly in line with the electrical data given in this
Manual. Also make sure that these components are compliant with
national and local codes.
• Use shielded cables (> 0.75 mm
wiring to avoid electromagnetic noise. (Shielded cable must be less
than 1000 m in total length and its size must be compliant with local
codes.)
• Check the connection of the power wiring terminals (terminals "L1"
to "L1" and "N" to "N"). AC supply voltage 3N~ 400V 50Hz. If it is
different, some components could be damaged.
• Follow the procedure indicated below to carry out the test
run. Make sure the test run is completed problem-free.

Where there are two remote controls (main and secondary), first carry out
the test run using the main remote control.
