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

NOTICE
Turn ON the power 6 hours before operation in order to have power running to the
crankcase heater and to protect the compressor.
