2.The old cylinder must be drained completely before removing. This is done by pushing the auto on/off/drain switch to the “drain” position.
3.When completely drained, push the auto on/off/drain switch to the “off” position.
4.Open the main disconnect during the entire cylinder change operation.
5.The power wires to the cylinder are attached by cylinder plugs to the electrode pins on top of the cylinder. Pull these plugs vertically off the pins. See Figure # 4.
6.Using slot screwdriver, loosen the steam hose clamp(s) and pull steam hose off vertically.
7.The cylinder is now ready to be lifted out of the unit.

1.The reverse procedure should be followed to install a new cylinder. The main disconnect is to be left open until the cylinder is completely installed and reconnected.
2.Ensure that the cylinder mounting stubs are seated properly in the allotted side mounting slots within the unit.
3.The white sensor plug on all units is for the sensor pin, which always goes on the single pin offset from the others. See Figure # 5.
4.Ensure that cylinder plugs are very snug on the pins.
5.For loose fitting plugs, a temporary solution is to squeeze plugs with a pair of pliers before installing. Since loose plugs may generate enough heat to melt and destroy the plug and cylinder new plugs must be ordered.
MAINTENANCE
WARNING! The plumbing and electrical compartments contain high voltage components and wiring. The access cover is attached with screws. Access should be limited to authorized personnel only.
EXTENDED SHUTDOWN
Before disconnecting power to the humidifier for a period of extended shutdown, ALWAYS DRAIN the cylinder first. Otherwise, the electrodes are subject to harmful corrosion which drastically shortens the cylinder life. Do NOT leave the switch in the DRAIN position indefinitely as the drain coil could burn out. Leave the switch in the OFF position and “open” the main external fused disconnect to stop power to the humidifier. Close the shut off valve in the water supply line feeding the humidifier.
TROUBLESHOOTING
TERMS USED
F.L.A. (Full Load Amps): Refers to amps listed on the humidifier specification label.
SHORT CYCLING: When the ‘on time’ of the humidifier is less than ten minutes upon a call for humidity. To correct short cycling, all humidifiers have a capacity adjustment which allows the output of the humidifier to be reduced to as low as 20% of rated output, thus extending the ‘on time’ required to maintain output.
FOAMING: The phenomenon which can occur in water when the impurities, already in the water reach an excess concentration as a result of boiling away pure water and the continued boiling action agitating the contained water. The humidifier electronics are designed to prevent this occurrence although in extreme cases, water will foam with little concentration making it necessary to have the drain time of the water, contained in the cylinder, increased.
