4. Setup

Follow these steps to set up your dehumidifier:

1. Unpacking: Carefully remove the dehumidifier from its packaging. Retain the packaging materials for future storage or transport.
2. Placement: Place the unit on a firm, level surface in the area where dehumidification is desired. Ensure there is at least 8 inches (20 cm) of space around the unit for proper air circulation. Avoid placing it near heat sources or in direct sunlight.
3. Power Connection: Ensure the power cord is securely plugged into a grounded electrical outlet.
4. Initial Operation: Allow the unit to stand upright for at least 24 hours before plugging it in and turning it on, especially if it was transported on its side. This allows the refrigerant to settle.
5. Mobility: The unit comes with 4 universal wheels for easy movement. Ensure they are securely attached if not pre-installed. Use the water tank handles for convenient lifting and positioning.

5. Operating Instructions

The dehumidifier features a touch control panel for easy operation.

Control Panel Overview:

The control panel includes buttons for power, mode selection, fan speed, timer, and humidity adjustment, along with an LED display showing current humidity and settings.

Operating Modes:

• Auto Mode: Press the "Mode" button to select Auto Mode. In this mode, the dehumidifier will automatically adjust its operation to maintain the desired humidity level you set. The unit will cycle on and off as needed.
• Continuous Mode: Select Continuous Mode for constant dehumidification. This mode is suitable for very damp environments where continuous moisture removal is required, such as flooded basements or laundry rooms.

Setting Humidity Level:

In Auto Mode, use the humidity adjustment buttons (usually up/down arrows) to set your desired humidity level between 30% and 80% Relative Humidity (RH).

Timer Function:

The 1-24 hour timer allows you to program the unit to turn on or off automatically after a set period. Press the "Timer" button and use the adjustment buttons to set the desired hours.

Child Lock:

To activate the child lock, press and hold the "Mode" button for 3 seconds. This will lock the control panel to prevent accidental changes. Repeat the action to unlock.

6. Drainage Options

Your COSTWAY dehumidifier offers three convenient drainage methods:

• Manual Drainage: The unit collects water in its internal 2.2-gallon (8.3 liter) water tank. When the tank is full, the unit will automatically shut off and an indicator light will illuminate. Carefully remove the water tank using its handles and empty it. Reinsert the tank securely to resume operation.
• Gravity Drainage: For continuous drainage without manual emptying, connect the included 2 ft (0.6 m) drain hose to the gravity drainage port on the unit. Ensure the hose is sloped downwards to allow water to flow by gravity into a suitable drain or container.
• Pump Drainage: For situations where a higher drainage point is required, use the built-in pump. Connect the included 6.5 ft (2 m) drain hose to the pump drainage port. The pump can lift water up to 16 ft (4.9 m) vertically, allowing drainage into a sink or higher drain.
