Key Features


When the system has an issue it switches off automatically, identifies the fault and displays the matching error code on the indoor unit. This allows the unit to be serviced more conveniently.

Long Distance Air Supply

The unit is designed to deliver volumes of cool air with airflow distances reaching up to 15 metres, reaching all parts of the room.

Set Temperature Display

The indoor unit features a translucent temperature display that is projected through the front panel only when the unit is on.

LCD Wireless Remote Control

The G Series air comes standard with a wireless remote control featuring both simple and advanced controls.

Self-Cleaning Function

An automated end of season cleaning process dries the inside unit if it is not going to be used for extended periods of time. This ensures the unit is free from mould, bacteria and dust.


The series features high quality components, with the outdoor unit equipped with blue fin condenser technology to provide protection from exposure to elements such as salt and rain. This helps to extend the lifecycle of the unit.

Can’t fault it RINV34RC 3.4KW

So far only used the heating function but it is very efficient at heating and keeping a constant temperature. The LED screen makes it easy to read the temperature and the remote control is easy to use. It is also very quiet. Look forward to trying out the cooling system over the summer.

Excellent unit RINV34RC 3.4KW

Perfect unit, it cools and heats my room very quickly. It’s not overly noisy when running and love the led temperature on the face of the unit, it’s relatively easy to use with the remote and doesn’t have a huge effect on the power bill. I highly recommend this unit.
