PUMP MAINTENANCE
Your PureAiro DSC 120ES is equipped with an integral condensate pump designed to
pump water from the dehumidifier out to the desired drain.
The pump requires routine maintenance that is not covered by the warranty.
Preventative maintenance is necessary to prevent issues from dirt and slime that may
accumulate in the drain system. This includes the drain pan, hose to the condensate
pump,pump reservoir, pump head assembly, and discharge tubing.
