Startup Procedure
Start Up Procedure
______ 1.
Prime water seal by removing overflow hose and adding water. Replace and tighten hose clamp.
______ 2.
With the power “off”, set the switch on the control board to the “Standby” position (the control board is
located within the humidifier control panel door).
______ 3.
Close the humidifier manual ball valve (located inside the humidifier evaporating chamber compartment).
______ 4.
Turn the controlling humidistat to the lowest setting (no call for humidity).
______ 5.
Turn the electric power “on” to the humidifier. The “Power” LED light on the controller should be illuminated.
______ 6.
Set the switch on the control board to the “Normal” position.
______ 7.
Open the water supply valve (by others) and allow the humidifier evaporating chamber to fill to the proper
level.
______ 8.
Make sure all the optional safety switches are satisfied (airflow proving switch, high
-
limit humidistat, etc.).
______ 9.
After the humidifier is full of water, the “Water Level Full” LED will illuminate. Turn humidistat up to call for
humidifier demand.
______ 10.
The heater(s) should energize on a call from the humidistat.
______ 11.
Verify the low water safety circuit by closing the water supply and opening the manual drain valve. As the
humidifier tank is draining, the “Water Level Full" light should go out and you should hear the contactor drop
out when the low water level is reached; this indicates the low water safety circuit is operational. This should
only take a couple of minutes maximum.
______ 12.
Close the drain valve and open the water supply, allow the humidifier to fill to the proper level.
______ 13.
Check operation of optional field
-
installed safety switches (airflow proving switch, high
-
limit humidistat, etc.)
to make sure that they turn the power off to the control circuit. The safety switches should shut
-
off the
humidifier heaters whenever one or more of the optional safety switches create an “open circuit”.
______ 14.
Check heater amperage draw by testing and recording voltage and amperage in each phase. Readings
should match the factory heater nameplate.
Amps A:_______ Amps B:______ Amps C:______
______ 15.
Inspect installation for leaks by operating humidifier at a full rolling boil. This may take up to 15 minutes from
a cold start. Any leaks should be sealed. Just tightening a pressure clamp will not work if the gasket is not
properly positioned between the sealing surfaces. If necessary, remove the cover, reseat gasket and
replace cover. A small amount of adhesive (super glue, gorilla glue, spray adhesive, etc.) to hold the gasket
in place while repositioning the cover will aid in this process.
______ 16.
After the unit is producing steam, check and retighten all hose clamp connections in the system and make
sure they are torqued to 35
-
40 in
-
lbs. There are two clamps on the fill line, two on the drain line and two on
the steam connections. There may be more located on the steam tube assembly (if used).
