Installation & Placement

Unpack and inspect contents. Place on level, stable surface.

  1. Positioning: Place at least 6 inches from walls and furniture for proper airflow.
  2. Level Surface: Ensure unit is level to prevent water leakage.
  3. Power Connection: Plug directly into a grounded 120V AC outlet; avoid extension cords.
  4. Drainage Setup: Attach garden hose to continuous drain port if using automatic drainage.

WARNING! Do not place in areas with temperatures below 41°F (5°C) or above 95°F (35°C). Keep away from heat sources and direct sunlight.

First-Time Setup

Power on dehumidifier; follow initial setup steps.

  1. Install Water Tank: Ensure tank is properly seated and locked in place.
  2. Set Desired Humidity: Use UP/DOWN buttons to select target humidity (recommended 45-50%).
  3. Select Mode: Choose between Continuous, Auto, or Timer mode.
  4. Check Filter: Verify air filter is clean and installed correctly.

CAUTION! Handle water tank with care to avoid spills. Ensure unit is unplugged during initial setup.

Specifications

Controls and Settings

  3. Timer Mode: Set unit to turn on/off at specific times (1-24 hours).

Tip: Use Auto mode for energy efficiency. In colder rooms, enable auto-defrost to prevent ice buildup.

Maintenance & Cleaning

Regular maintenance ensures optimal performance and longevity.

  1. Clean Air Filter: Remove and wash filter every 2-4 weeks with warm water and mild detergent. Dry completely before reinstalling.
  2. Empty Water Tank: Empty tank regularly or use continuous drainage. Clean tank with mild solution monthly.
