Rated Voltage : 220 V +/- 10%
The electric components will be damaged when
the voltage is too high. If the voltage is too low,
the compressor will vibrate violently to damage
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
power capacity and air switch with enough space.

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
