User Manual for Della 048-TL-W8KW Mini Compact Air Conditioner

Quick guide from the manual

This air conditioner is designed for window installation. Before use, ensure you have a grounded 3-prong outlet. Do not use extension cords or plug adapters. The unit uses R32 refrigerant, which requires specific handling and safety precautions. Always ensure the unit is tilted slightly (about 3 degrees) toward the outside to allow for proper condensate drainage.

Installation and assembly

Before installing, ensure your window meets the width requirements: 23-36 inches for the 8K model, or 26-36 inches for the 10K/12K models. Ensure the lower sash allows for at least 14.5-16 inches of vertical clearance.

1. Assemble the top mounting rail to the unit using the provided screws.
2. Place the unit into the window opening, ensuring the frame is against the window sill.
3. Extend the side accordion panels to fit the window frame.
4. Secure the frame lock between the frame extensions and the window sill using the provided screws.
5. Drive locking screws through the frame holes into the window sash to secure the unit.
6. Install the sash lock to secure the lower window sash in place.
7. Insert the foam seal into the space between the upper and lower sashes.

Troubleshooting

If you encounter issues, check the following:

• Unit won't start: Ensure it is plugged in, the circuit breaker is not tripped, or the LCDI plug needs to be reset.

• Water dripping inside: Ensure the unit is tilted slightly toward the outside for drainage.
• Remote not working: Check battery orientation or replace the batteries.
