• HRV • VKM-GA(M)V1
When asking your dealer to repair, inform related staff of the details as follows:
•
Shipping date and installation date:
•
Malfunction:
Inform the staff of the defective details.
(Malfunction code being displayed on the remote controller.)
•
Name, address, telephone number
Repair where 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 discontinued, we have the related important parts in stock
for 6 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.
Taking apart 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.
•
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.)
•
Operation of the product is assumed to be 10 hours/day, 2500 hours/year.

*1 :
•
When the fan motor fails, the remote controller does not display 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 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.
•
When used in hot, humid locations or locations where temperature and humidity fluctuate greatly.
•
When used in locations where power fluctuation (voltage, frequency, 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.
