The Panasonic CU-3Z68CBE is a 3-connection Free Multi Z outdoor condensing unit, built to run up to three 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 for homes and small offices where running three separate outdoor units isn't practical or permitted.
Rated at 6.8kW nominal cooling and 8.5kW nominal heating, the CU-3Z68CBE supports a combined indoor capacity range of 4.5kW to 11.2kW, giving installers real freedom to mix and match indoor unit types and sizes across a project — from compact bedrooms to open-plan living spaces — without needing matching capacities on every port.

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: Minimum Two Indoor Units Must Be Connected
The CU-3Z68CBE is designed to run 2 or 3 indoor units — at least two must be connected for the system to operate correctly. The combined nominal cooling capacity of all connected indoor units must fall within the 4.5kW–11.2kW connectable range.
Good to Know: A++ Energy Efficiency
The CU-3Z68CBE achieves an SEER of 8.20 and SCOP of 4.60, both rated A++ on the current European energy label scale, reflecting Panasonic's current-generation Free Multi Z platform.
Three Independent Zones From One Outdoor Unit
A single compact condenser drives up to three rooms with individual temperature control on each, cutting down on external wall space, pipework runs, and visible outdoor equipment compared to installing three single-split systems.
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.
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.
Wide Heating Operating Range
Rated to operate in heating mode down to -15°C outdoor ambient, making it a genuine year-round heat pump solution for UK winters, not just a summer air conditioning unit.
Compact Footprint For Flexible Siting
At 795mm (H) x 875mm (W) x 320mm (D), the unit's compact dimensions make it easier to site on balconies, flat roofs, or against garden walls where space for outdoor plant is limited.

How many indoor units can I connect to the CU-3Z68CBE?
Between 2 and 3 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-3Z68CBE 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 on 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 4.5kW and 11.2kW. Exceeding this range is not supported by the manufacturer.
How efficient is the CU-3Z68CBE?
It achieves an SEER of 8.20 (A++) and an SCOP of 4.60 (A++), placing it among the more efficient units in Panasonic's current domestic Free Multi Z range.
Can this unit provide heating in cold UK winters?
Yes. The CU-3Z68CBE 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.
