Monthly
Clean pump check valve and basin. In normal use,
dust can accumulate and can restrict airflow, reducing
performance and causing the unit to overheat. Clean
when dust accumulation is visible. Remove grills and
cover as shown in Fig. B. Use a vacuum cleaner with a
brush tool and a soft cloth to remove any debris. Take
care not to damage any interior components.
To maintain appearance, wipe interior and exterior sur-
faces with a damp cloth. For deep cleaning and a last-
ing, protective shine, use an automotive interior cleaner.
As Needed

the message “ER9 PUMP BLOCKED PUMP & HOSE”,
