F-Gas Certification Required
Please note: We are legally required to verify your F-Gas certification before supplying restricted refrigerants. Orders without valid certification will not be processed.

The Panasonic CU-5Z90CBE is the largest outdoor unit in Panasonic's Free Multi Z range, built to run up to five independently controlled indoor units from a single external condenser. It uses the R32 refrigerant and an inverter-driven rotary compressor to deliver flexible, room-by-room heating and cooling across larger homes without needing five separate outdoor units cluttering the exterior.
Rated at 9.0kW nominal cooling and 10.4kW nominal heating, the CU-5Z90CBE supports a combined indoor capacity range of 3.2kW to 18.3kW, giving installers real freedom to mix and match indoor unit types and sizes across a whole-house project.
Important: F-Gas Qualified Installation Required
This unit is charged with R32, a fluorinated greenhouse gas covered by F-Gas Regulations. Installation, commissioning, and any refrigerant handling must be carried out by an F-Gas certified engineer. See the certification form above before ordering.
Please Note: Confirm Total Combined Indoor Capacity
With five connections available, it's straightforward to exceed the outdoor unit's rated capacity when combining several larger indoor units. The combined nominal cooling capacity of all connected indoor units must stay within the 3.2kW–18.3kW range — check the total against the specific indoor unit combination before ordering, particularly on five-zone layouts.
Good to Know: Minimum Two Indoor Units Must Be Connected
The CU-5Z90CBE is designed to run 2 to 5 indoor units — at least two must be connected for the system to operate correctly. Indoor unit sizes can be mixed and matched across wall-mounted Etherea, TZ super-compact, cassette, and duct types, provided total connected capacity stays within the outdoor unit's rated range.
Five Independent Zones From One Outdoor Unit
A single outdoor unit drives up to five rooms with individual temperature control on each, significantly reducing the outdoor footprint compared to installing separate condensers for a whole-house system.
Inverter-Driven Rotary Compressor
The inverter compressor modulates output to match real-time demand across all connected rooms rather than cycling on and off, which improves comfort, reduces electricity use, and lowers operating noise.
A+++ SEER Efficiency
Achieves an SEER rating of 8.50 (A+++) and an SCOP of 4.68, placing it among the most efficient units in Panasonic's domestic multi-split range.
Wide Indoor Unit Compatibility
Compatible with Panasonic's Etherea wall-mounted, TZ super-compact wall-mounted, 60x60 cassette, and low static pressure hideaway duct indoor units, so each connected room can use the indoor style that best suits the space.
R32 Refrigerant for Lower Environmental Impact
R32 has a lower global warming potential than the R410A refrigerant it replaces, while also improving system efficiency — helping the unit meet current and future F-Gas phase-down requirements.
Long Maximum Pipe Run
Supports a total pipe length of up to 80 metres across all connections, giving installers more flexibility to site the outdoor unit further from the rooms it serves on larger properties.

How many indoor units can I connect to the CU-5Z90CBE?
Between 2 and 5 indoor units can be connected. At least two must be connected for the system to run — it cannot be operated with only one indoor unit fitted.
What indoor unit types are compatible with this outdoor unit?
The CU-5Z90CBE supports Panasonic's Etherea wall-mounted, TZ super-compact wall-mounted, 60x60 grid cassette, and low static pressure hideaway duct indoor units, allowing different room types to use different indoor styles across the same outdoor unit.
Does this outdoor unit need an F-Gas certified installer?
Yes. The unit is charged with R32 refrigerant, which falls under F-Gas Regulations. Installation and any refrigerant work must be carried out by an installer holding valid F-Gas certification, which we verify before shipment.
What is the maximum total indoor capacity I can connect?
The combined nominal cooling capacity of all connected indoor units must fall between 3.2kW and 18.3kW. Exceeding this range is not supported by the manufacturer, so it's worth checking the total against your specific indoor unit combination, especially on larger five-zone layouts.
How far can the outdoor unit be sited from the indoor units?
The CU-5Z90CBE supports a total combined pipe length of up to 80 metres across all connections, with a maximum run of 25 metres to any single indoor unit and an elevation difference of up to 15 metres.
Can this unit provide heating in cold UK winters?
Yes. The CU-5Z90CBE is rated to operate in heating mode down to -15°C outdoor ambient temperature, making it suitable as a genuine year-round heat pump rather than a cooling-only summer unit.
