Con
fi
rm that the valve of the refrigerate pipe of the
outdoor unit is OPEN.
• Before turning on the power, con
fi
rm that the
resistance between the terminal block of power
supply and the earth is more than 1M
Ω
using a 500V
megohmmeter.
Do not run the unit if it is less than 1M
Ω
.
CAUTION

the compressor.
To save the compressor when it is activated, leave
the power on for more than 12 hours.
Methods of test run
¿
When executing a test run using
a remote controller
Operate the system normally to check the running
condition using the wired remote controller. Follow
the instructions in the supplied owner’s manual when
operating the unit.
If you use a wireless remote controller for operations,
follow the instructions in the installation manual
supplied with the indoor unit.
To execute a test run forcibly under the condition that
the thermostat automatically turns the unit off due to
the indoor temperature, follow the procedure below.
The forcible test run will automatically stop after 60
minutes to prevent continuous forcible running and
return to normal running.
CAUTION
Do not use forcible running except for a test run as it
overloads the unit.
¿
When executing a test run using
the interface P.C. board on the
outdoor unit
You can execute a test run by operating switches
on the interface P.C. board of the header outdoor
unit. “Individual trial”, which tests each indoor unit
separately, and “corrective trial”, which tests all the
indoor units connected, are available.
<Individual test operation>
