Portable unit shows P2; cooling stops until water is drained.

Safety: Turn off and unplug the unit before draining.

Steps to clear P2:

• Drain upper tank: Locate the upper drain outlet (usually mid-height on the rear). Place a container under it and remove the cap to drain water.
• Clean drain port: Use a small brush or toothpick to clear any debris from the drain opening.
• Check float/sensor: If accessible, open the rear panel and inspect the upper tank float switch. Ensure it moves freely and is not obstructed.
• Replace faulty switch: If the float switch does not change continuity when moved, replace the upper tank float switch.
• Reassemble and test: Reinstall drain caps securely to prevent leaks, then restart the unit.
