CAUTION
Do NOT perform the test operation while working on the indoor units.
When performing the test operation, NOT only the outdoor unit, but the connected
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.
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 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.
