■ 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.
