Step 5 If a low-temperature component is configured, connect the pipe to the low-
temperature component.
NO TE
Top or bottom piping does not affect the installation of the low-temperature component.
However, the following requirements must be met:
● If the height difference between the outdoor unit and the indoor unit is greater than 5
m, the low-temperature component must be installed indoors.
● If the low-temperature component is placed lower than the indoor unit, the height
difference between the top of the low-temperature component and the bottom of the
indoor unit cannot exceed 500 mm.
