Minimum storage period of important parts

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.
