Structure mechanism and Installation
•Operating condition
Please operate air conditioner in the correct conditions as follows.
COOL mode operation
DRY mode operation
Outdoor temperature should be in
range of 18˚C to 43˚C.
Otherwise it is possible for air
conditioner to breakdown.
Outdoor temperature should be in
range of 18˚C to 43 ˚C.
Otherwise it is possible for air
conditioner to breakdown.
Room humidity should be lower
than 90%. Otherwise, it is possible
for air conditioner to dew at the
surface and even drop water after
running for a long period of time,
but this is normal.
Please refer to P.4 for indoor
temperature range.
•Power requirement
- 3 -
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.
To ensure the reliable earthing, please do not connect
earth wire to the following places:

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
be 2 drain trays provided.
Select the appropriate drain
tray according to actual
condition.

Operation procedure
•Operation Tips
Operation for comfort and economy
Do not overcool the room
temperature. This is not
good for health and
causes wasting of
electricity.
Keep the blind or curtains
closed. Do not let sunshine
entering the room directly
when the air conditioner is
in operation.
Keep the room temperature
consistent. Adjust the vertical
and horizontal airflow direction
to ensure consistent
temperature
in the room. Air can’t be
discharged to 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 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 the cool air leakage.
