Connecting Drainage

For continuous operation, use the drain hose connection.

Turn off and unplug the unit.

Route the hose to a floor drain, sink, or sump pump. Ensure the hose path is downhill without kinks.
Replace the empty water bucket. The unit will now drain continuously.

Tip: Check the hose periodically for clogs or leaks.

Auto Mode: Unit cycles on/off automatically to maintain the set humidity level. Most energy-efficient.
Continuous Mode: Runs the compressor and fan continuously until turned off or the bucket is full.
Turbo Mode: Runs fan at highest speed for maximum air circulation and faster dehumidification.
Timer Mode: Set to turn the unit On or Off after a delay of 1-24 hours.

WARNING! Do not block air intake or exhaust grilles. Operate only within specified temperature range.

Maintenance & Cleaning

Unplug unit before any maintenance.
