The Panasonic CS-TZ42CKEW is a 4.2kW wall-mounted indoor unit from the TZ super-compact range, sitting between the smaller 3.5kW model and the larger 5.0kW option. nanoe X air purification is built in as standard, working continuously to help keep the room's air cleaner.

Suited to mid-sized bedrooms, living rooms, and home offices, the CS-TZ42CKEW pairs with the dedicated CU-TZ42CKE single outdoor unit or a compatible Free Multi Z multi-split outdoor unit, giving installers flexibility over whether the room runs on its own condenser or shares one with other zones.

Important: F-Gas Qualified Installation Required

This indoor unit operates with R32 refrigerant circulated from its outdoor unit, and falls under F-Gas Regulations. Installation and commissioning must be carried out by an F-Gas certified engineer. See the certification form above before ordering.

Please Note: Confirm Outdoor Unit Compatibility Before Ordering

The CS-TZ42CKEW is sold as an indoor unit only. It must be paired with a compatible Panasonic outdoor unit — either the dedicated single unit CU-TZ42CKE, or a Free Multi Z multi-split outdoor unit such as the CU-3Z52CBE, CU-3Z68CBE, or CU-4Z68CBE. Confirm the total combined indoor capacity on any multi-split system stays within the outdoor unit's rated range.

Good to Know: What nanoe X Does

nanoe X generates hydroxyl radicals that are released into the room to help inhibit airborne pollutants, certain bacteria and viruses, and odours, working continuously alongside the heating or cooling function or independently when the unit is in standby.

Super-Compact Cabinet

At just 290mm high, 765mm wide, and 214mm deep, the TZ super-compact cabinet keeps a low visual profile, including fitting above a door where wall space is limited.

nanoe X Air Purification Built In

Continuous release of hydroxyl radicals works to inhibit airborne pollutants and odours as standard, with no separate filter cartridge to replace.

Mid-Range Output for Everyday Rooms

Delivers 4.2kW cooling and 5.0kW heating, giving it enough headroom for typical bedrooms, living rooms, and home offices without the higher output — or higher running cost — of the larger TZ models.

Built-In Wi-Fi Control

Integrated Wi-Fi connects directly to the Panasonic Comfort Cloud app for remote scheduling and control, and the unit is compatible with Google Assistant and Amazon Alexa voice control.

Aerowings Directional Airflow

Aerowings louvre technology directs airflow more precisely around the room, helping even out temperature across the space rather than blowing directly on occupants.

Quiet Operation

Runs as low as 25 dB(A) in quiet mode, keeping background noise low in bedrooms and other spaces where a quiet indoor unit matters.

Does the CS-TZ42CKEW include an outdoor unit?

No. This listing is for the indoor unit only. It must be paired with a compatible Panasonic outdoor unit, either a dedicated single unit or a Free Multi Z multi-split outdoor unit.

What is nanoe X and does it need maintenance?

nanoe X is Panasonic's air purification technology, which releases hydroxyl radicals into the room to help inhibit pollutants, certain bacteria and viruses, and odours. It runs continuously with the unit and does not require a separate filter cartridge to be replaced.

What size room is this unit suitable for?

At 4.2kW nominal cooling, the CS-TZ42CKEW suits typical bedrooms, living rooms, and home offices — larger than the smaller 2.0kW–3.5kW TZ models but without the higher output of the 5.0kW and 6.0kW versions.

How quiet is this unit in normal use?

Sound pressure runs from 44 dB(A) on high fan speed down to 25 dB(A) in cooling quiet mode.

Can this indoor unit run on a multi-split outdoor unit?

Yes. The CS-TZ42CKEW is compatible with Panasonic's Free Multi Z outdoor units, including the CU-3Z52CBE, CU-3Z68CBE, and CU-4Z68CBE, provided the combined nominal cooling capacity of all indoor units connected stays within that outdoor unit's rated range.

Does installation need to be carried out by a certified engineer?

Yes. As the system circulates R32 refrigerant, installation must be carried out by an F-Gas certified engineer. We require evidence of certification before shipment.
