Key Features

Easy Installation

Levelling adjusters are provided, preventing damage to the wall. Generous pipe length (20–30 metres) is provided, so there is no need to worry about distance to the outdoor unit.

Built-in Weekly Timer

Temperature settings and On/Off control can be managed over a period of one week, using a Weekly Timer.

Simple Design

Surfaces that were uneven have been smoothed to provide a simple design with linear beauty, which will fit with all types of interiors.

R32 Refrigerant

Enables increased energy efficiency and a significant reduction in 'Global Warming Potential Factor' - great for the environmentally conscious.


The new MFZ-KJ has achieved much better energy-saving performance compared with previous MFZ-KA models, in both cooling and heating.

Multi-flow Vane

The airflow is controlled by three uniquely shaped vanes that allow the freedom to customise comfort according to preferences.

Works Wonderfully Well

It works really well for both heating and cooling.
We use it mostly for heating, as it is so economical to run compared to most other forms of heating.
We have a very large and long lounge and it has the capacity to warm all of it.
We also installed the Wi-Fi interface. Which is great. As long you an internet service you can turn it on with your phone from any where. Eg. before leaving work or on the way home, or before you get out of bed even.
