Device Description

The device consists of a control panel, signal receptor, transport handle, cold air outlet, remote controller, exhaust duct, evaporator inlet, drain holes, and air exhaust duct connectors.

Control Panel

The control panel includes buttons for power, mode selection, fan speed adjustment, timer setting, temperature control, and various indicators for different functions.

Operation of the Control Panel

Each mode has specific working principles as described below:

• Auto Mode (J): Automatically selects cooling, fan, or heating mode based on room temperature.
• Dehumidify Mode (L): Operates the dehumidifying function with specific fan and compressor settings.
• Cool Mode (K): Cools the room by controlling the compressor and fan based on set temperature.
• Fan Mode (M): Runs the fan without activating the compressor for air circulation.
• Heat Mode (R): Provides heating function based on room temperature settings.
• Timer Operation (N): Allows setting automatic on/off times for the device.
• Swing Mode (O): Controls the vertical louver movement for air distribution.

Warning

Ensure proper drainage through the drain holes when operating in varying humidity conditions. Use the included plastic pipe for comfortable water drainage.

   To operate the device, aim the remote controller at the signal receptor. The remote controller will operate the device at distance 5 meters when pointing at signal receptor of the device.

PROTECTIVE DEVICES

The protective device may trip and stop the appliance in the cases listed below:

1. at cooling mode: indoor air temperature is over 43°C (109°F)
2. at cooling mode: room temperature is below 15°C (59°F)
3. at dehumidifying mode: room temperature is below 15°C (59°F).

If the device runs in cooling “K” or dehumidify “L” mode with door or window opened for a long time when relative humidity is above 80%, dew may drip down from the outlet. The protective device will work in the following cases:

1. Restarting the device immediately after stopping work or changing the selected mode while working, you must wait 3 minutes.
2. If the plug has been removed, after restarting the device will return to the original mode, all timer’s setting must be set again.

REMARK: there is condensing water recycling hidden within this unit. The condensing water is partly kept recycling between the condenser and the water plate. When the water level rises to the upper level, the float switch and water full indicator (E4) lights on to remind draining water. Please cut off the power supply, move the appliance to a suitable place, remove the drain plug, drain water completely. After the drain, re-install the plug, or the appliance may leak and make your room wet.

If the appliance is placed in a position admitting drain water, you also can connect the pipe to the drain hole to drain out the water. Drain pipe is added to kit, inner diameter 9mm , outer diameter 12mm, material: PVC.
