5.2 Continuous Draining Option
For continuous operation without emptying the bucket, you can connect a standard garden hose (not included) to the unit's low-level drain. The unit includes an adapter with a clear hose that pushes onto a smooth plastic fitting inside the unit. This adapter has male hose threads for attaching a garden hose. Ensure the hose is routed downwards to a suitable drain to allow gravity to remove the water.
5.3 Limpeza do filtro de aire
The 'Filter' indicator light will remind you when it's time to clean the air filter. A clean filter ensures efficient operation and better air quality. To clean, lift the filter straight up from the top at the front corner of the unit and slide it out. Wash the filter with warm, soapy water, rinse thoroughly, and allow it to air dry completely before reinserting.
