About the SCM80ZS-W
The Mitsubishi Heavy Industries SCM80ZS-W is a high-performance outdoor unit that serves as the heart of a versatile multi-split air conditioning system. Designed for both residential and commercial applications, it delivers powerful and efficient climate control to multiple spaces from a single, compact external unit. With a nominal cooling capacity of 8.0kW and a heating capacity of 9.3kW, it is well-suited for conditioning several rooms within a large home, a suite of offices, or a small retail environment.
One of the system's key advantages is its flexibility. The SCM80ZS-W can connect to between two and four individual indoor units, allowing for customised temperature control in each zone. This enables you to mix and match different types of indoor units, such as wall-mounted, floor-standing, ceiling cassette, or concealed channel models, to best suit the aesthetics and requirements of each room. It is important to note, however, that this model is not compatible with FDUM series ducted indoor units. This modular approach ensures optimal comfort and efficiency, as you only need to heat or cool the rooms that are in use.
Energy efficiency is a core feature of the SCM80ZS-W, which boasts an A++ energy label for both cooling (SEER 8.2) and heating (SCOP 4.6). This high rating is achieved through the use of an advanced inverter-driven twin rotary compressor and the adoption of R32 refrigerant. R32 is a next-generation refrigerant with a significantly lower Global Warming Potential (GWP) than older R410A, and its superior thermodynamic properties mean less energy is required to achieve the desired temperature, reducing running costs and environmental impact.
Installation is made flexible by the generous piping allowances. The system supports a total pipe length of up to 70 metres and a maximum height difference of 20 metres between the outdoor and indoor units, providing considerable freedom in positioning the units. The outdoor unit comes pre-charged with refrigerant for up to 30 metres of pipework, simplifying the installation process. Please be aware that this product is the outdoor unit only. All indoor units, piping, and accessories must be purchased separately. To comply with UK regulations and to validate the manufacturer's warranty, the system must be installed and commissioned by a qualified F-Gas certified engineer.

Frequently asked questions
How many indoor units can I connect to the SCM80ZS-W?
You can connect between two and four indoor units to this outdoor unit, allowing you to control the climate in multiple rooms independently.
What type of indoor units are compatible?
This outdoor unit is compatible with a wide range of Mitsubishi Heavy Industries R32 indoor units, including wall-mounted, floor-standing, ceiling-suspended, and cassette models. However, it is not compatible with the FDUM series ducted units.
What refrigerant does the SCM80ZS-W use?
It uses R32 refrigerant, which has a lower Global Warming Potential (GWP) than older refrigerants like R410A and offers improved energy efficiency.
Do I need a professional to install this unit?
Yes, in the UK it is a legal requirement that this system be installed and commissioned by an F-Gas certified engineer to ensure safety, compliance with regulations, and to validate the manufacturer's warranty.
