According to the local safety regulations, use a qualified power supply circuit and circuit break.

• Operating condition
  Please operate the air conditioner in the correct conditions as follows. COOL mode operation| DRY mode operation
  ---|---
  The outdoor temperature should be in the range of 18˚C to 43˚C.
  Otherwise, it is possible for the air conditioner to break down.
  Room humidity should be lower than 90%. Otherwise, it is possible
  for the air conditioner to dew at the surface and even drop water after
  running for a long period of time, but this is normal.

  If it cannot, iron support has to be used outdoors. Iron support should be fixed on the building (Shown in the right figure.)
  ● Use sunshade board
  The air conditioner should avoid anything to be dropped onto it and avoid direct sunlight. If there is no cover on it, you should contact the seller for installing the sunshade board. When installing the sunshade board, don’t let it block the air inlet at the side grille. |
• Installation

Drain water for another style :

To get 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.

* For RAW-VJ18SCASK and RAW- VJ24SCASK, there will be 2 drain trays provided.
Select the appropriate drain tray according to the actual condition.

Note:
Due to different installation environments and humidity, it is recommended that customers consider installing an external large drain pan and connecting to drain the 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.

• Notes for installation**
  Removal**
  Before removing the air conditioner from the other place, you should contact the seller first.
  Then it must be done under the direction of a professional technician.|

• Operation Tips
Operation for comfort and economy

Do not overcook the room temperature. This is not
good for health and causes a wasting of electricity.| Keep the blinds or curtains closed. Do not let sunshine enter the room directly when the air conditioner is in operation.| Keep the room temperature consistent. Adjust the vertical and horizontal airflow direction
to ensure the consistent temperature in the room. Air can’t be discharged in the direction of air-in.
---|---|---
| |
Make sure that the doors and windows are tightly closed. Avoid opening doors and windows frequently in order to keep the air conditioning in the room.| Clean the air filter regularly. Blockages of the air filter reduce dehumidifying effects. Clean the air filter at
least once every two weeks.| Ventilate the room occasionally. Since windows are kept closed, it is a good idea to open them
and ventilate the room. When starting the unit, curtains or windows should be closed to prevent cool air leakage.

Care and maintenance

• Caution
Operations for safety and health

1. The plug must be accessible after the appliance is positioned.
2. Do not use this appliance in the laundry.
3. If the power cord is damaged, it must be replaced by the manufacturer or its service agent to avoid hazards.

• Do not pull out the power cord.
• Damage to the cord may result in serious electric shocks.| • Do not use the air conditioner for other purposes except for cooling the room.
• Do not use the air conditioner for other purposes such as drying clothes, preserving foods, or cultivating vegetables.| • Do not block the air intake and outlet vents. This causes reduced performance and irregular operation.
• Do not insert sticks or other objects into these vents as it is dangerous to touch the electric components and the fan.
---|---|---
| |
Select the optimal temperature. Pay attention to adjusting the temperature to suit the conditions. Rooms occupied by infants, the elderly, or the sick should be kept under an appropriate temperature.| Do not use heating apparatuses in the vicinity.
The air conditioner’s plastic parts will melt if exposed to excessive heat.| Avoid exposing the body directly to airflow for long periods.
This is not recommended for health reasons.
| |
Always wait at least 3 minutes before switching the air conditioner on again after you have switched it off during cooling.|

• Cleaning and maintenance

1. Cut the power off before cleaning.
2. Use a soft cloth when deaning the cabinet. If the cabinet is very dirty, dip doth into warm water below 403C dry the cloth, and then rub off the dirt.
3. Don’t use gas, benzene, solvent wash, chemical solvent, etc. for cleaning.
4. Do not splash water directly into the unit, in which there are micro-computer and circuit plates, they must not be drenched with water.

Air filter
The air filter behind the intake grille should be washed at least once every two weeks or as often as it needs cleaning.
How to clean the air filter:

1. To remove the air intake grille, grasp the tab on the filter and pull to take out
2. Vacuum the filter on the dusty side to remove light dust.
3. Wash the filter, cleaner side up under gently flowing water to wash out accumulated dust and lint.
4. If the filter is very dirty, clean it with mild household detergent in water.

Let the filter dry thoroughly before reinstalling it. If necessary, please ask the professional personnel to clean it.

* Check if the air inlet and outlet of the unit are blocked or not.

• Troubleshooting guide
Please check the following items before asking for repair, it saves your time and money.

• Is the plug out?
• Is the power fuse or switch off?
• Whether the voltage is too high or too low?
  Cooling efficiency is not good.| * Is the air inlet or outlet blocked?
• Is there any other heat source in the room?
• Are air filters dirty?
• Is the indoor fan speed set at LOW? Maybe the room is too hot when the unit starts.
  Foggy air flows out.| At COOL mode operation, sometimes there is foggy air flowing out from the unit, this is because the room’s humid air has been cooling rapidly.
• The unit is normal while the indoor outlet is sending out some odor, because the inlet air may be mixed with the smell of furniture and smoke.
  The air conditioner operation is noisy.| * For a noise that sounds like water flowing:
  This is the sound of freon flowing inside the air conditioner unit.
• For a noise that sounds like a shower, This is the sound of the dehumidifying water being processed inside the air conditioner unit.
  It seems that condensate is leaking from the air conditioner.| Condensate occurs when the airflow from the air conditioner cools the warm room air.
  The air conditioner does not operate for about 3 minutes when restarted.| * This is to protect the mechanism.
• Wait about 3 minutes and operation will begin.

Care and maintenance

Immediately stop all operations and plug out or isolate the power supply, please contact your dealer in the following situations.

• Operation starts or stops abnormally;
• Power fuse or switch often breaks;
• Carelessly splash water or something into the air conditioner;
• Electrical lines are much hot or lines cover breaks;
• Burning smell or smoke formed.
  *Other strange situations.|

Others
Model and rated value of fuse shall be subject to screen print on the corresponding controller or protective bushing.

• After-sales service
If your air conditioner has questions about quality or malfunction, please contact the service center.
