Repair after the warranty term is expired
Contact your dealer. If necessary to repair, pay
service is available.
•
Minimum storage period of important parts
Even after a certain type of air conditioner is dis-
continued, 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 techni-
cal expertise, so we recommend entering a main-
tenance 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 stop-
ping of the machine.
(Although it varies with the model, we recom-
mend 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.
• Table 1 “Inspection Cycle” and “Maintenance
Cycle” Lists
Note 1
This table indicates main parts.
See the maintenance and inspection contract for
details.
Note 2
This maintenance cycle indicates recommended
lengths of time until the need arises for maintenance
work, in order to ensure the product is operational
as long as possible.
Use for appropriate maintenance design (budgeting
maintenance and inspection fees, etc.).
Depending on the content of the maintenance and
inspection contract, the inspection and maintenance
cycles may in reality be shorter than those listed
here.
Shortening of “maintenance cycle” and
“replacement cycle” needs to be considered in
the following cases.
1. When used in hot, humid locations or locations
where temperature and humidity fluctuate
greatly.
2. When used in locations where power fluctuation
(voltage, frequency, wave distortion, etc.) is high.
(Cannot be used if it is outside the allowable
range.)
3. When installed and used in locations where
bumps and vibrations are frequent.
4. When used in bad locations where dust, salt,
harmful gas or oil mist such as sulfurous acid
and hydrogen sulfide may be present in the air.
5. When used in locations where the machine is
started and stopped frequently or operation time
is long. (Example:
24 hour air-conditioning)
