• Table 1 “Inspection Cycle” and “Maintenance Cycle” Lists

*1:

• When the fan motor fails, the remote controller does not dis-

play any error code.
Usage under that status will lead to insufficient ventilation.
The air supply and exhaust fans should be checked once
every one or two months.

• You can make a simple check such as below way.

To check the wind flow, hold a bar of which the end has a
string or other similar lightweight item over the supply grille
and exhaust grille.

*2:

• When the solenoid valve fails, the remote controller does not

display any error code.
Usage under that status will lead to insufficient humidification
and increased tap water consumption.
The solenoid valve should be checked at the biginning of the
heating season.

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 mainte-
nance 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.

• When used in hot, humid locations or locations where tem-

perature and humidity fluctuate greatly.

• When used in locations where power fluctuation (voltage, fre-

quency, wave distortion, etc.) is high.
(Cannot be used if it is outside the allowable range.)

• When installed and used in locations where bumps and

vibrations are frequent.

• 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.

• When used in locations where the machine is started and

stopped frequently or operation time is long. (Example:
24 hour air-conditioning)

• When the supply water is hard water the humidifier’s life

become shorter.
