4. Installation Walkthrough

4.3. Indoor Unit Installation

4.3.1. Choosing an installation location

1) The indoor unit should be installed indoors, mounted on a wall, and have the water outlet aimed

downwards.

The indoor unit must operate in a dry, well-ventilated location.

There should be no volatile, corrosive, or flammable liquids or gases nearby.

Ideally, the unit should be as close as possible to the water supply system.

Try and leave enough space in the area around the unit to simplify future maintenance.

The minimum dimensions of surrounding gaps suitable for the unit to operate correctly is as follows:
