The Hisense ADT52UX4RCL8 indoor unit is specifically designed for multi-split air conditioning systems. With a capacity of 18000 BTU, this ducted unit provides efficient cooling or heating for spaces ranging from 35m² to 40m². Choosing a multi-split system allows you to connect one outdoor unit to multiple indoor units, offering space-saving benefits and installation flexibility. It is important to ensure that the outdoor unit has sufficient capacity to support the connected indoor units, and the piping should not exceed the limits specified by the manufacturer. For installation, a false ceiling is required along with additional materials such as piping and vents.
