Temporary Use of an Adapter
We strongly discourage the use of an adapter due to potential safety hazards. For temporary connections,
use only a genuine adapter, available from most local hardware stores. Ensure that the large slot in the
adapter is aligned with the large slot in the receptacle for a proper polarity connection.
To disconnect the power cord from the adapter, use one hand on each to avoid damaging the ground
terminal. Avoid frequently unplugging the power cord as this can lead to eventual ground terminal damage.
• Never use the appliance with a broken adapter.
Temporary Use of an Extension Cord
We strongly discourage the use of an extension cord due to potential safety hazards. In neccessary case ,
use “UL- listed 3 - wire grounded” refer CSA standard only to increase the cable at 15A ,125V .

Operation Tips!
Do not overcool the room.
Keep blinds or curtains
closed.
This is not good for the health and
wastes electricity.
Make sure that the
doors and windows
are shut thight.
Avoid opening doors and
windows as much as
possible to keep the cool
air in the room.
Do not let direct sunshine enter
the room when the air conditioner
is in operation.
Clean the air filter
regularly.
Blockages in the air filter
reduce the airflow and
lower cooling and
dehumidifying effects.
Clean at least once every
two weeks.
Keep the room temperature
uniform.
Adjust the vertical and horizontal
airflow direction to ensure a
uniform temperature in the room.
Ventilate the room
occasionally.
Since windows are kept
closed, it is a good idea
to open them and
ventilate the room now
and ten.
Use high fan speed
for effective and fast
cooling.
The unit gives its rated
cooling capacity when the
