WARNING! Risk of improper humidifier-canister maintenance. Can cause smoke and fire,
activation of fire suppression systems, building evacuation, dispatching of fire/rescue
equipment and personnel, and catastrophic canister failure resulting in water leaks, equipment
damage, injury, or death. Using a humidifier canister that has reached the end of it’s service life
can be extremely hazardous. If the canister cannot be replaced immediately at the end of life
condition, turn Off the power and water supply to the humidifier and remove the canister until a
replacement canister can be installed. Do not ignore humidifier problem alarms. Resetting
humidifier without addressing cause may result in fire or damage due to leaking water.
CAUTION: Risk of contact with hot surfaces. Can cause burn injury. The humidifier canister
and steam discharge lines are extremely hot during operation. Allow sufficient time for them to
cool to a touch-safe temperature before handling. Use extreme caution and wear appropriate,
OSHA-approved PPE when performing maintenance on the humidifier.
After an extended period of operation, in accordance with life-expectancy information, the cylinder is
completely used as indicated by the amber high-water sensor light illuminated on the cabinet. Then this
condition is reached, a new replacement cylinder must be installed.
NOTE: The amber high-water sensor light may come on during initial start-up, but this instance does
not indicate that the cylinder should be replaced.
The steam cylinder is disposable and must be replaced at the end of the cylinder's life. Cylinder life will
vary according to water-supply conditions and humidifier use.
9.4.1 Operating the Humidifier
1. During startup, when the humidity control calls for humidification, the fill valve opens and
allows water to enter the canister. When the water level reaches the electrodes, current flows
and the water begins to warm. The canister fills until the amperage reaches the setpoint and
the fill valve closes. As the water warms, its conductivity increases and the current flow, in turn,
rises. If the current reaches 115% of the normal operating current, the drain valve opens and
drains some of the water out of the canister. This reduces electrode contact with the water and
lowers the current flow to the amperage setpoint. Boiling soon commences, and the canister
operates normally.
2. If the conductivity of the water is low, the canister fills and the water level reaches the canister
full electrode before the current setpoint is reached. The humidifier stops filling to prevent
overflow. Boiling should commence in time. As water is boiled off, the mineral concentration in
the canister increases and current flow also increases. The canister eventually reaches full
output and goes to normal operation. No drain is permitted until then.
3. When full output is reached the circuit board starts a time cycle which is factory-set at
60seconds. During this repeating time cycle, the fill valve will open periodically to replenish the
water being boiled off and maintain a “steady state” output at the setpoint. The amperage
variance depends on the conductivity of the water.
4. After many cycles, the mineral concentration in the canister becomes too high. When this
occurs, the water boils too quickly. As the water quickly boils off and less of the electrode is
exposed, the current flow decreases. When the current crosses the low threshold point before
the end of the time cycle, the drain valve opens, draining the mineral-laden water out and
replacing it with fresh water. This lowers the mineral concentration and returns the canister to
“steady state” operation and prolongs canister life. The frequency of drains depends on water
conductivity.
