About the SRC71ZR-W
The Mitsubishi Heavy Industries SRC71ZR-W is the robust and highly efficient outdoor component of a 7.1kW split air conditioning system. As the engine of the system, this premium inverter unit is engineered to deliver powerful and reliable climate control for larger residential spaces, commercial offices, or specialised applications like server rooms. It pairs with a compatible indoor unit, such as those in the SRK-ZR Diamond Series, to create a complete and sophisticated heating and cooling solution.
At its core, the SRC71ZR-W utilises advanced inverter technology. Unlike traditional fixed-speed systems that are either fully on or off, the inverter-driven compressor precisely adjusts its speed to meet the exact cooling or heating demand of the room. This intelligent modulation results in significantly lower energy consumption, stable temperature maintenance without uncomfortable fluctuations, and quieter operation. With a nominal power consumption of just 1.93kW for cooling and 1.95kW for heating, it offers an economical way to manage your indoor climate.
The unit provides a substantial nominal cooling capacity of 7.1kW and an even more impressive heating capacity of 8.0kW, making it suitable for year-round use in the UK. Its versatility is further enhanced by an exceptionally wide operating temperature range. It can reliably provide heating in ambient temperatures as low as -15°C and deliver cooling in conditions ranging from -15°C up to a scorching 46°C. This makes it an ideal choice not only for comfort cooling and heating but also for environments that require constant cooling, such as IT and communications rooms, regardless of the outside weather.
Embracing modern environmental standards, the SRC71ZR-W operates on R32 refrigerant. R32 has a much lower Global Warming Potential (GWP) than the older R410A refrigerant, making it a more eco-conscious choice that aligns with current F-Gas regulations. The unit comes pre-charged with 1.5kg of refrigerant, sufficient for a pipe run of up to 15 metres, simplifying the installation process.
Installation flexibility is a key design feature. The system supports a maximum total pipe length of up to 30 metres and a significant maximum height difference of 20 metres between the indoor and outdoor units. This generous allowance provides considerable freedom in positioning the outdoor unit discreetly, whether on a ground-level concrete pad, a flat roof, or mounted on wall brackets. Its robust construction ensures it can withstand the elements, providing long-lasting performance. Please note, to ensure safety, legal compliance, and to validate the manufacturer's warranty, the installation of this unit and the entire system must be carried out by a qualified and F-Gas certified engineer.

Frequently asked questions
Is this a complete air conditioning system?
No, this is only the outdoor unit (condenser). It must be paired with a compatible Mitsubishi Heavy Industries indoor unit, such as the SRK71ZR-W, to function as a complete split system.
What refrigerant does the SRC71ZR-W use?
This unit uses R32 refrigerant, which is more environmentally friendly with a lower Global Warming Potential (GWP) compared to older refrigerants like R410A.
What is the maximum pipe length for this unit?
The maximum total pipe length between the indoor and outdoor units is 30 metres. The unit is pre-charged for up to 15 metres, with an additional charge required for longer runs.
Can I install this air conditioner myself?
No. In the UK, it is a legal requirement that any air conditioning system containing F-Gas refrigerants, such as this one, is installed by a certified F-Gas engineer. Self-installation is illegal and will void the warranty.
