 Danger

 

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.

 Warning

 

Do not disassemble, modify or repair the unit.

 

This may cause water leakage, electric shock or fire.

 

Contact your local dealer.

 

Do not remove or reinstall the unit by yourself.

 

Incorrect installation may cause water leakage, electrical shock or fire.

 

Contact your local dealer.

 

When asking your local dealer to repair, inform related staff of the details as follows:

 

Model name and product No. of air conditioner

 

Shipping date and installation date

 

Malfunction:  
 

Inform the staff of the defective details. (Malfunction code being displayed on the remote controller.)

 

Name, address, telephone number

 

Repair after the warranty term is expired

 

Contact your local dealer. If necessary to repair, pay service is available.

 

Minimum storage period of important parts

 

Even after a certain type of air conditioner is discontinued, we have the related important parts in stock for 9 years at least. 
The important parts indicate parts essential to operate the air conditioner.

 

Recommendations for maintenance and inspection

 

Since dust collects after using the unit for several years, the performance will be deteriorated to some extent. 
Disassembling and cleaning inside require technical expertise, so we recommend entering a maintenance and inspection 
contract (at a cost) separate from normal maintenance.

 

Recommended inspection and maintenance cycles

 

[Note: The maintenance cycle is not the same as the warranty period.]

 

Table 1 assumes the following usage conditions.

1.  Normal use without frequent starting and stopping of the machine. 

(Although it varies with the model, we recommend not starting and stopping the machine more than 6 times/hour for 
normal use.)

2.  Operation of the product is assumed to be 10 hours/day and 2,500 hours/year.
