Do not connect or adjust any wiring or connections unless
the main power switch is OFF.
When using more than one power source, check and
ensure that all of them are turned OFF before operating
the indoor unit.
Avoid wiring installation in contact with the refrigerant
pipes, water pipes, edges of plates and electrical
components inside the unit to prevent damage, which may
cause electric shock or short circuit.
After changing the input settings, output settings and auxiliary
sensor settings on the master controller, it needs to be
Use a dedicated power circuit for the indoor unit. Do not use
