Recommended inspection and maintenance cycles
Be aware that the mentioned maintenance and replacement cycles
do not relate to the warranty period of the components.
Table 1: "Inspection Cycle" and "Maintenance Cycle" list
Table 1 assumes the following conditions of use:
1. Normal use without frequent starting and stopping of the unit.
Depending on the model, we recommend not starting and
stopping the machine more than 6 times/hour.
2. Operation of the unit is assumed to be 10 hours/day and 2,500
hours/year.
12.2. Shortening of "maintenance cycle" and
"replacement cycle" needs to be considered in
following situations
■
The unit is used in locations where:
1. heat and humidity fluctuate out of the ordinary
2. power fluctuation is high (voltage, frequency, wave distortion,
etc.)
(The unit cannot be used if power fluctuation is outside the
allowable range.)
3. bumps and vibrations are frequent
4. dust, salt, harmful gas or oil mist such as sulfurous acid and
hydrogen sulfide may be present in the air
5. the machine is started and stopped frequently or operation time
is long (sites with 24 hour air-conditioning).

Recommended replacement cycle of wear parts
Table 2: "Replacement Cycle" list
Contact your dealer for details.
■
Moving and discarding the unit
■
Contact your dealer for removing and reinstalling the total
unit. Moving units requires technical expertise.
■
This unit uses hydrofluorocarbon.
Contact your dealer when discarding this unit. It is required
by law to collect, transport and discard the refrigerant in
accordance with the "hydrofluorocarbon collection and
destruction" regulations.
WARNING
■
Do not modify, disassemble, remove, reinstall or
repair the unit yourself as incorrect dismantling or
installation may cause an electric shock or fire.
Contact your dealer.
■
In case of accidental refrigerant leaks, make sure
there are no naked flames. The refrigerant itself is
entirely safe, non-toxic and non-combustible, but it will
generate toxic gas when it accidentally leaks into a
room where combustible air from fan heaters, gas
cookers, etc. ... is present.
Always have qualified service personnel confirm that
the point of leakage has been repaired or corrected
before resuming operation.
