A standard back-to-back setup involves positioning the indoor and outdoor units directly opposite each other on the same outer wall, typically within 3 meters (extensions possible). To facilitate connection, a wall opening is created for the gas pipelines and electrical wires, which are then neatly sealed and covered for both protection and visual appeal. Additionally, an accessible power outlet on this wall is necessary for installing an external isolator.
The positioning of the outdoor unit offers a degree of flexibility, allowing it to be adjusted laterally to better meet your preferences. This installation method is also applicable to properties with multiple stories, where the outdoor unit may be secured on a bracket or placed on a solid base, depending on the wall’s construction. Generally, the placement of the indoor unit directly above windows or doors is to be avoided.
