Setup and Installation
Proper installation ensures safe and efficient operation of your washing machine. Follow these steps carefully:
- Unpacking: Carefully remove all packaging materials, including any protective films or foam inserts. Ensure all accessories are present.
- Placement: Place the washing machine on a firm, level surface to prevent vibration and noise during operation. Avoid placing it in direct sunlight or in areas with high humidity. Ensure there is adequate space around the machine for ventilation and access.
- Water Connection: Connect the water inlet hose to a cold water tap. Ensure the connection is secure to prevent leaks. The twin tub design typically requires manual filling of the wash tub.
- Drainage: Position the drain hose to allow for proper water discharge. The hose should be placed in a sink or a standpipe, ensuring it is not kinked or blocked.
- Power Connection: Plug the power cord into a grounded electrical outlet. Ensure the voltage matches the requirements specified on the product label. Do not use extension cords.

Operating Instructions
Follow these steps for effective washing and spinning:
Washing Cycle
- Load Laundry: Open the wash tub lid and place clothes loosely inside. Do not overload the tub beyond its 15 kg capacity.
- Add Detergent: Add the appropriate amount of detergent directly into the wash tub.
- Fill with Water: Fill the wash tub with water to the desired level.
- Select Wash Intensity: Turn the 'Intensidad de Lavado' (Wash Intensity) knob to select 'Normal' or 'Fuerte' (Strong) depending on the soil level of your clothes.
- Set Wash Time: Turn the 'Tiempo de Lavado' (Wash Time) knob to set the desired wash duration, up to 15 minutes. The machine will start washing automatically.
- Drain Water: Once the wash cycle is complete, turn the 'Selector de Válvula' (Valve Selector) knob to 'Drenar' (Drain) to empty the water from the wash tub.
Rinsing and Spinning Cycle
- Transfer Clothes: Carefully transfer the washed clothes from the wash tub to the spin tub. Distribute them evenly to ensure balance.
- Rinsing (Optional): For rinsing, you can either fill the wash tub with clean water and run a short wash cycle, then drain, or manually rinse clothes under running water before spinning.
- Secure Spin Tub: Close the inner and outer lids of the spin tub. Ensure clothes are not protruding.
- Set Spin Time: Turn the 'Tiempo de Centrifugado' (Spin Time) knob to set the desired spin duration, typically up to 5 minutes. The machine will begin spinning.
- Remove Clothes: Once the spin cycle is complete, open the lids and carefully remove the spun clothes.

Maintenance
Regular maintenance helps prolong the life of your washing machine and ensures optimal performance.
- Lint Filter Cleaning: The machine includes a lint filter. Regularly remove and clean the lint filter located inside the wash tub to prevent lint buildup and ensure efficient washing. Rinse it under running water and reinsert.
- Exterior Cleaning: Wipe the exterior of the washing machine with a soft, damp cloth. Do not use abrasive cleaners or solvents that could damage the surface.
- Tub Cleaning: Periodically clean the inside of the wash and spin tubs. You can run a short cycle with hot water and a cup of white vinegar to remove detergent residue and odors.
- Drain Hose: Ensure the drain hose is free from blockages and kinks.
- Storage: If the machine will not be used for an extended period, ensure both tubs are completely drained and dry. Store in a dry, well-ventilated area.
