the refrigerant system and easily cause the

compressor and electric components not working.

The ground must be connected. Special socket must

be used. Furthermore, the socket and wiring must

conform to the wiring regulations. And the earthing

method must be reliable. In fixed circuit, there must

be electricity leakage protection switch of enough

Drain water for another style :

To get the maximum cooling efficiency, the air conditioner is designed

to splash the condensate on the condenser coil. Please install the

drainage tray when installing the air conditioner if necessary.

To the cooling only unit, if the splashing sound annoys you, you can

use an outside drain as shown in the following procedure. However, it

may reduce the performance.

1. Slide out the chassis from the cabinet.

2. Remove the rubber plug from the body base plate.

3. Install the drain tray to the corner of the cabinet with 2 screws.

4. Connect the drain hose to the outlet on the drain pan bottom.

5. Slide the chassis into its original place in the cabinet.

Note:

Due to different installation environments and humidity, it is recommended

that customers consider installing an external large drain pan and connect

to drain hose.

All costs and whether the location of the external large drain pan and drain

hose are suitable for installation, please consult with qualified installers.

For RAW-VJ18SCASK and

RAW-VJ24SCASK, there will
