Before You Begin

Product Description

Our powerful portable air conditioners serve as excellent cooling solutions for single rooms, creating a comfortable atmosphere in your space. Additionally, they feature ventilation and dehumidifying functions to circulate air and remove moisture. These self-contained systems do not require any permanent installation, allowing you to move them to the space where they are most needed. They are commonly used in kitchens, temporary residences, computer rooms, garages, and other places where installing an Outdoor Unit is impractical. The environmentally friendly R32 is used as the refrigerant. R32 has no damaging influence on the ozone layer (Ozone Depleting Potential - ODP), a negligible greenhouse effect (Global Warming Potential - GWP), and is available worldwide. Due to its efficient energy properties, R32 is highly suitable as a coolant for this application. Special precautions must be taken into consideration due to the coolant's high flammability.

In the event of a power loss, there is a 3-minute delay to protect the compressor before it restarts.

Drainage

Manual Drainage

1. When the machine stops after the water is full, please unplug the power plug. Note: Move the machine carefully to avoid spilling water from the water pan at the bottom of the body.
2. Place the water container below the side water outlet behind the body.
3. Unplug the water plug, and the water will automatically flow into the water container.

Continuous Drainage

The self-evaporating system utilizes collected water to cool the condenser coils for better efficiency. There is no need to empty the drainage tank during cooling operation, except in drying operation and high humidity conditions. The condensate water evaporates at the condenser and is expelled through the exhaust hose. For continuous or unattended operation in drying mode, please connect the provided drain hose to the unit. Condensate water will automatically flow into a bucket or drain by gravity.

• Switch off the unit before operating.
• Remove the plug from the water outlet opening and keep it in a safe area.
• Securely and properly connect the drain hose, ensuring it is not kinked and clear of obstruction.
• Place the hose outlet over a drain or bucket, ensuring that water can freely flow out of the unit.
• Do not submerge the end of the hose in water, as it can cause an "Air Lock" in the hose.

To Avoid Water Spillage:

• Due to the significant negative pressure of the condensate drain pan, tilt the drain hose downward toward the floor. The appropriate degree of inclination should exceed 20 degrees.
• Straighten the hose to prevent any traps from forming in the hose.

Cleaning and Care

Cleaning the Air Filter (Every Two Weeks)

Dust collects on the filter and restricts airflow. The restricted airflow reduces the efficiency of the system, and if it becomes blocked, it can cause damage to the unit.
