Like everything else about the Hybrid System, maintenance is simple, well thought out and easily done. Essentially, it consists of regular filter changes. The filters are located on the front of the unit for easy access. In the vertical stacked model all mechanical components are located in the removable chassis. In the event of unit failure the chassis can be removed and replaced with an operating chassis in a matter of minutes. This can be done by the property's maintenance staff, making the Hybrid unit fully operational again with minimal downtime. The chassis can then be repaired at a convenient location. Central system components require simple a scheduled maintenance program as recommended by the manufacturer.
