Field Setting and Test Run
Run the humidifier
<LZ-H***GXH 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 eco-V 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 at
intervals of several 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.
If carpentry work is not completed when a test run is finished, tell the customer not to run the humidifi-
er for the protection of indoor unit and eco-V until it is completed.
If the humidifier is run, paint, particles generated from adhesive and other materials used for carpentry
work may cause eco-V to get dirty, causing splash or leakage of water.
