Display shows P2, unit may run but with limited cooling (portable models)

Safety: Unplug the unit before draining.

Steps to address P2:

• Drain condensate: Follow the same procedure as for P1: remove the lower drain plug and drain water into a pan.
• Clean drain path: If P2 recurs quickly, flush the internal drain path with a small amount of warm water and a mild vinegar solution to remove algae or scale (avoid spilling inside the electronics).
• Check float movement: Ensure the float moves freely and is not obstructed by dirt or foreign objects.
• Continuous drain option: Consider connecting a continuous drain hose to the designated port and routing it to a floor drain to prevent future P2 alerts.
