Usage Precautions 

 WARNINGS 

Failure to observe the instructions contained in a WARNING may result in death or severe injury.

 

 

Be sure to install this product in accordance with the instructions given 
in this manual.   

Improper installation may lead to water leakage, electric shock, or fire. 

Installation should be carried out by your dealer or by a qualified installation 
engineer.  

Improper installation may lead to water leakage, electric shock, or fire. 

Electrical work should be carried out in accordance with the instructions 
given in this manual. 

Use dedicated circuitry only. Improper workmanship or insufficient electrical capacity 
may result in electric shock, fire, or other hazard. 

Be sure to use the specified cord types.   

Fasten power cords to terminals such that the connection area is isolated from 
external forces. Improper connection or poorly fastened cords may lead to electric 
shock or fire. 

 

Do not modify this product. 

Improper modification of the internal wiring or piping may lead to electric shock or 
fire. Unauthorized modification will void the warranty.

 

 

Do not change the settings of safety devices.

Changing the safety setting may lead to product damage or fire. 

Do not install this product in areas where flammable gas leaks may 

occur. 

Presence of flammable gas around this product may result in fire. 
 

Do not install this product in areas where corrosive gas, organic 

solvent or chemical solution exists in the atmosphere, or where there 

is a chance that any of those can adhere to the product. 

Contact with such substances can lead to corrosion of the product which may result 
in electric shock or fire. 

Do not install where the product could easily be exposed to water. 

Exposure to water splash or rain could lead to electric shock or fire. 

Do not place combustibles near the product. 

Sparks from switching could cause ignition of combustibles.

 

 

Be sure to provide proper grounding. 

Do not connect ground lines to gas or water pipes, lightning rods, etc. Improper 
grounding may lead to electric shock.
