Caution

  Do not use the unit until the qualified technician instructs you that it is safe 

to do so.

  Do not place appliances that produce naked flames in the path of the airflow 

from the unit. The airflow from the unit may increase the rate of combustion, 
which may cause a fire and cause serious injury or death. Alternatively, the 
airflow  may  cause  incomplete  combustion  which  can  lead  to  reduced 
oxygen concentration in the room, which can cause serious injury or death.

  Only use the air conditioner for its intended purpose. This unit should not be 

used to provide refrigeration or cooling for food, plants, animals, machinery, 
equipment or art.

  Do not insert your fingers or other objects into the unit’s air inlet or air outlet 

to avoid injury or damage to the equipment.

  The  fins  on  the  unit’s  heat  exchanger  are  sharp  and  can  cause  injury  if 

touched. To prevent injury, when the unit is being serviced, gloves should 
be worn or the heat exchanger should be covered.

  Do not place items which might be damaged by moisture under the unit. When 

the humidity is greater than 80% or if the drain pipe is blocked or the air filter is 
dirty, water could drip from the unit and damage objects placed under the unit.

  Ensure that the drain pipe functions properly. If the drain pipe is blocked by 

dirt or dust, water leaks may occur when the unit is running in cooling mode. 
If this happens, turn the unit off and contact your supplier or service engineer.

•     Do not touch the internal parts of the controller. Do not remove the 

front 

 panel. Some internal parts may cause injury or be damaged.

  Ensure  that  children,  plants  and  animals  are  not  directly  exposed  to  the 

airflow from the unit.

  When fumigating a room with insecticide or other chemicals, cover the unit 

well and do not run it. Failure to observe this caution could lead to chemicals 
getting  deposited  inside  the  unit  and  later  emitted  from  the  unit  when  it 
running, endangering the health of any room occupants.

  Do  not  dispose  of  this  product  as  unsorted waste.  It  must  be  separately 

collected and  processed.  Ensure  that  all applicable  legislation  regarding 
the disposal of refrigerant, oil and other materials is adhered to. Contact your 
local waste disposal authority for information about disposal procedures.

  To avoid damaging the remote controller, exercise caution when using it and 

replacing its batteries. Do not place objects on top of it.

  Do not place appliances that have naked flames under or near the unit, as 

heat from the appliance can damage the unit.

  Do not place the unit’s remote controller in direct sunlight. Direct sunlight 

can damage the remote controller’s display.

  Do  not  use  strong  chemical  cleaners  to  clean  the  unit,  as  doing  so  can 

damage the unit’s display or other surfaces. If the unit is dirty or dusty, use 
a slightly damp cloth with very diluted and mild detergent to wipe the unit. 
Then, dry it with a dry cloth.

  Children shall not play with the appliance.
