1.1.3 Next, Run the Humidifier
<VKM-GAMV1 series only>
1. Check that the water supply piping is connected securely.
2. Open the water supply shut-off valve. (No water will be supplied at this time.)
3. Run the HRV unit in heating mode.
(See the operating manual included with the indoor unit for details on how to run the unit in
heating mode.)
The water supply will start and the humidifier will begin operation.
4. After starting heating (humidifying), the sound of the water supply solenoid valve will be
heard every 3 or 4 minutes (a clicking sound), so listening for that clicking sound let the unit
run for 30 minutes to make sure that humidifying operation is normal.
CAUTION If carpentry work is not completed when a test run is finished, tell the customer not to run the
humidifier for the protection of indoor unit and HRV until it is completed.
If the humidifier is run, paint, particles generated from adhesive and other materials used for
carpentry work may cause HRV to get dirty, causing splash or leakage of water.
