CAUTION
Do NOT perform the test operation while working on the indoor units or the heat
exchanger unit.
When performing the test operation, NOT ONLY the compressor unit will operate,
but the heat exchanger unit and the connected indoor units as well. Working on an
indoor unit or the heat exchanger 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.
INFORMATION
During the first running period of the unit, the required power may be higher than
stated on the nameplate of the unit. This phenomenon is caused by the compressor,
that needs a continuous run time of 50 hours before reaching smooth operation and
stable power consumption.
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 compressor unit, the heat exchanger unit and the indoor
units will start up. Make sure that the preparations of the heat exchanger unit and
all the indoor units are finished (field piping, electrical wiring, air purge, ...). See
installation manual of the indoor units for details.
1 After the installation of the unit, check the items listed below.
