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. See
Table 9.4 on page 80, for alarm corrective actions.
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.
