After-sales service and warranty
After-sales service:
Warning
• Do not modify the unit.
This may cause electric shock or fire.
• Do not disassemble or repair the unit.
This may cause electric shock or fire.
Contact your dealer.
• If the refrigerant leaks, keep out of fire.
Although the refrigerant does not usually leak, if the refrigerant
leaks out into a room and comes in contact with the combustible
air in the equipment such as fan heater, stove, oil (gas) cooker,
etc., it will cause toxic gas to be generated.
When a refrigerant leakage failure has been repaired, confirm a
service person that the leakage point has been corrected surely
before restarting operation.
• Do not remove or reinstall the unit by yourself.
Incorrect installation may cause electrical shock or fire.
Contact your dealer.
• When asking your dealer to repair, inform related staff of the
details as follows:
• Product No. of air conditioner:
Refer to the warranty card.
• Shipping date and installation date:
Refer to the warranty card.
• Malfunction:
Inform the staff of the defective details.
(Malfunction code being displayed on
the remote control.)
• Name, address, telephone number
• Repair where the warranty term is expired
Contact your dealer. If necessary to repair, pay service is avail-
able.
• 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 con-
ditioner.
• Recommendations for maintenance and inspection
Since dust collects after using the unit for several years, the per-
formance will be deteriorated to some extent.
Taking apart 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,
2500 hours/year.
