Two-dimensional bar code 
is a code for manufacturing.

• Read these Safety Precautions carefully to ensure correct installation.

• This manual classifies the precautions into DANGER, WARNING and CAUTION. Be sure to follow all the 

precautions below: they are all important for ensuring safety.

• After completing installation, test the unit to check for installation errors. Give the user adequate instructions 

concerning the use and cleaning of the unit according to the Operation Manual.

• Refrigerant gas is heavier than air and replaces oxygen. A massive leak could lead to oxygen depletion, especially in 

basements, and an asphyxiation hazard could occur leading to serious injury or death.

• Do not install unit in an area where flammable materials are present due to risk of explosion resulting in serious 

injury or death.

• If the refrigerant gas leaks during installation, ventilate the area immediately.

Refrigerant gas may produce a toxic gas if it comes in contact with fire such as from a fan heater, stove or cooking device. 
Exposure to this gas could cause severe injury or death.

• After completing the installation work, check that the refrigerant gas does not leak.

Refrigerant gas may produce a toxic gas if it comes in contact with fire such as from a fan heater, stove or cooking device. 
Exposure to this gas could cause severe injury or death.

• Do not ground units to water pipes, telephone wires or lightning rods because incomplete grounding could cause a 

severe shock hazard resulting in severe injury or death, and to gas pipes because a gas leak could result in an 
explosion which could lead to severe injury or death.

• Do not ground units to telephone wires or lightning rods because lightning strikes could cause a severe shock hazard 

resulting in severe injury or death, and to gas pipes because a gas leak could result in an explosion which could lead 
to severe injury or death.

• Safely dispose of the packing materials. 

Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries. 
Tear apart and throw away plastic packaging bags so that children will not play with them. 
Children playing with plastic bags face the danger of death by suffocation.

• The following safety symbols are used throughout this manual:

Be sure to observe this instruction.

Be sure to establish an earth connection.

Never attempt.
