Open up the Control Panel and observe the tank and if you see a cloudy, wet
tank along with the gurgling noise of water then
fog. If the tank is clear and you can see to the bottom of it then it is not
working.

For verifying the amount of moisture being produced measure the air
conditions before the DTA and then downstream of it. You should m
both a decrease in dry bulb temperature and an increase in relative humidity.
Plot these on a Psychometric chart or call the Factory for further interpolation.

Moisture migrates very quickly.
humidified zone are closed or not opened long. Make sure no new or un
foreseen sources of outside air have been introduced to the space being
humidified as this will increase the load on the humidifier.

b.

Verify that the blower fan is turning on when there is a call for humidification
and not just when there is a call for heat. There is a dry contact relay in the
panel for exactly this purpose. Contact the Installer to verify that he utilized
this relay and that
has been set up to run the fan only when there is a call for humidification.
Also make sure that the necessary zone dampers are also opening to allow
moisture to be delivered to the appropriate space

c.

Make sure the air filters to the furnace/blower/heat pump are not completely
clogged and restricting air flow.

d.

Verify that the amperage draw for the 120VAC and 48VAC side of the circuits
are at or near the rated amount for that system. If it is
ratings then some of the UPC
this is the case.

Unit is Cycling – the fill solenoid valve is going on and off too frequently as well as the
‘Fog On’ lite.

a.

Check water supply
to fill the tank. Open the tank and observe the rate of fill

b.

Verify that the RO System has had ample time to charge the system (this can
take several hours depending on the
supply piping to the humidifiers.

c.

Ensure that there is enough ‘house’ pressure in the domestic water supply
that feeds the RO System. A minimum of 35 PSI is required.
