To ensure that you choose the correct size Power Unit for your Chameleon Retractable Hose System, it is important to remember that the system uses only one retractable hose point at a time.
Just because you have lots of retractable hose points, doesn't mean that you need a big unit. The length of the pipe run to the fartherest point will determine the size of the Power Unit. To maximize coverage, install retractable hose points in central areas.
A well-located Chameleon Retractable Hose Point with a 15mt hose can cover up to 2,200 sq. ft. of living space. Selecting a Power Unit with strong suction and substantial airflow is important to provide proper hose retraction.

* This is a standard guideline - Power Units may need to sized up or down depending on installation circumstance.
