1. SAFETY PRECAUTIONS

Please read these “SAFETY PRECAUTIONS” carefully before installing air conditioning unit and be sure to 
install it correctly.
After completing installation, conduct a trial operation to check for faults and explain to the customer how to 
operate the air conditioner and take care of it with the aid of the operation manual. Ask the customer to store 
the installation manual along with the operation manual for future reference.

This air conditioner comes under the term “appliances not accessible to the general public”.

Safety Precaution

This unit is a class A product. In a domestic environment this product may cause radio interference in which 
case the user may be required to take adequate measures.

Meaning of WARNING and CAUTION notices

WARNING

 .........Failure to follow these instructions properly may result in personal injury or loss of life.

CAUTION

 ..........Failure to observe these instructions properly may result in property damage or per-

sonal injury, which may be serious depending on the circumstances.

WARNING

•

Ask your dealer or qualified personnel to carry out installation work.
Do not attempt to install the air conditioner yourself. Improper installation may result in water leakage, electric 
shocks or fire.

•

Install the air conditioner in accordance with the instructions in this installation manual.
Improper installation may result in water leakage, electric shocks or fire.

•

Consult your local dealer regarding what to do in case of refrigerant leakage. When the air conditioner is to 
be installed in a small room, it is necessary to take proper measures so that the amount of any leaked refrig-
erant does not exceed the concentration limit in the event of a leakage. 
Otherwise, this may lead to an accident due to oxygen depletion.

•

Be sure to use only the specified accessories and parts for installation work.
Failure to use the specified parts may result in the unit falling, water leakage, electric shocks or fire. 

•

Install the air conditioner on a foundation strong enough to withstand the weight of the unit.
A foundation of insufficient strength may result in the equipment falling and causing injury.

•

Carry out the specified installation work after taking into account strong winds, typhoons or earthquakes.
Failure to do so during installation work may result in the unit falling and causing accidents.
