blocked?
Remove anything that might be blocking them.

(To protect the unit, turn the power on at least 6 hours
before operating it. This makes operation smoother.)

(3) Supply water

(Start of heating season)

4.3.2 AT THE END OF THE SEASON
(1) On a clear day, use fan only operation for around half a

day to thoroughly dry out the interior of the unit.

• Refer to page 7 for details on fan operation.

(2) Turn off the power

• When the power is shut off, the characters in the remote

controller display disappear.

(End of heating season)

4.4 INSPECTION AND MAINTENANCE OF THE

HUMIDIFIER <VKM-GAMV1 series only>

• Have your dealer do the following inspections in order

to get the longest use.

• In order to prevent harmful bacteria from generating, ask

your dealer to do maintenance on humidifying unit portion at
the beginning or the end of the heating season.

NOTE

• 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 beginning of the
heating season.

For dealers

4.5 INSPECTION OF THE FAN MOTER

NOTE

• 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.

4.6 REPLACING THE HUMIDIFIER ELEMENT

<VKM-GAMV1 series only>

• The humidifier element needs to be replaced regularly.

The humidifier element should in general be replaced once
every three years when supply water is soft water, but out-
side factors (If the water quality is hard water, etc.) as well
as operating conditions (24-hour-a-day air conditioning, etc.)
may shorten its productive life.

• Contact your dealer if you have any questions.
