CAUTION
Before starting up the system, make sure:
▪ The indoor and outdoor unit wiring is completed.
▪ The switch box covers of the indoor and outdoor units
are closed.
NOTICE
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.

To perform a test operation
1 Confirm that the indoor unit gas and liquid stop valves are open.
INFORMATION
It is possible that the pressure inside the refrigerant circuit
does not rise, despite the opened stop valve. This can be
due to the expansion valve (or the like) blocking the
refrigerant, and does not obstruct the test run.
