After installing the outdoor and indoor units, test the Cool
and Heat modes.
• When you test the Cool mode, set the set temperature
of the indoor unit to the lowest one. And when you test
the Heat mode, set the set temperature of the indoor
unit to the highest one.
• Check if each indoor unit operates normally and
then also check if all indoor units operate normally
together.
Check both of the Cool and Heat modes.
• About 20 minutes after the air conditioner is started,
check the temperature difference between the air
inlet and outlet of the indoor unit. If the temperature
difference is larger than the value given in the
