indoor unit will operate as well. Working on an indoor unit while performing a test
operation is dangerous.
CAUTION
Do NOT insert fingers, rods or other objects into the air inlet or outlet. Do NOT
remove the fan guard. When the fan is rotating at high speed, it will cause injury.
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.
During test operation, the outdoor unit and the indoor units will start up. Make
sure that the preparations of all indoor units are finished (field piping, electrical
wiring, air purge, ...). See installation manual of the indoor units for details.
After the installation of the unit, first check the items listed below. Once all checks
are fulfilled, the unit MUST be closed. Power-up the unit after it is closed.
