  3. Check flooring: Ensure surface is dry and can support weight (unit is heavy when bucket is full).
  4. Power connection: Plug directly into a grounded 120V AC outlet; avoid extension cords.

WARNING! Do not place near heat sources or in areas with temperatures below 41°F (5°C). Ensure all packaging materials are removed.

First-Time Setup

  2. Choose mode: Select NORMAL, TURBO, or DRY (for laundry) using the MODE button.
  3. Set timer (optional): Use TIMER button to program automatic shut-off or start-up.
  4. Check filter: Ensure washable filter is installed correctly behind the front grille.
  5. Bucket placement: Insert empty water collection bucket securely until it clicks.

CAUTION! Handle the unit with care; use two people if moving. Do not operate without the filter installed.
