●Before installation, make sure you read all the “Safety precautions”.

●The precautions herein provide very important points regarding safety. Make sure you follow them.

●Symbols used in this manual are categorized as follows according to the degree of risk when used improperly:

Describes precautions that must be observed to prevent danger of injury or death of the user.

Describes precautions that must be observed to prevent damage to the unit.

●After installation, describe the user “Safety precautions”, how to use, and how to care for and clean the unit following the operation manual, 

  and test run the unit to confirm whether there are any problems.
  In addition, direct the user to keep this installation manual together with the operation manual, and, should the users change, to give the manuals 
  to the new user.

Installation must be properly done following this installation manual.

●If the unit is installed improperly, water leakage, electric shock, or fire

  may result.

Make sure that heat insulation for refrigerant piping is properly 
installed to prevent bedewing.

●If heat insulation is not done properly, bedewing of the surfaces such 

  as piping may result, which will make the ceilings, floors, or other 
  valuable items wet.

●Insulation for the joint part must be done after an airtightness test.

Ask the dealer or an authorized technician to install the unit.

●If the unit is installed improperly by the user, water leakage, electric    

  shock, or fire may result.

Do not place polyethylene bags in reach of young children.

●Putting them over head will block breathing passages, which could 

  result in suffocation.

Use proper electrical cables to meet the standard for current capacity.

●If improper electrical cables are used, short circuit, electric shock, or 

  fire may result.

Do not use the unit in an unusual environment.

●If used in an environment with a large amount of volatile oil (including 

  mechanical oil), steam, or sulfidizing gas or where it is high in salt 

  content such as a seashore where the outdoor unit may become
  blocked by snow, performance may drop significantly or parts may
  become damaged.

Drain piping must be done properly according to the installation 
manual to drain water and must be heat insulated to prevent 
bedewing.

●If piping is not properly installed, water leakage may result, which 

  will make the ceilings, floors, or other household items wet.
