How To Maintain a Skuttle Steam Humidifier
Because the Skuttle steam humidifier is designed to emit mineral-free
moisture into the air, the unit should be cleaned and serviced every two-
to-four months. Harder water, colder weather and/or higher humidistat
settings will increase the frequency of cleaning and service.
NOTE: Some 60-series models are equipped with a Skuttle Automatic
Flushing Timer (see page 35), which can reduce maintenance significantly.
However, it is still wise for the homeowner to check the humidifier for
mineral buildup every two months or so during the humidification season.
To perform routine maintenance tasks, follow these instructions:
WARNING: Do not touch the humidifier when the operation indicator
light is on. Always unplug the unit and allow it to cool prior to
service or inspection.
1. Unplug the humidifier and fan control; disconnect the humidistat
wires from the external screw terminals.
2. Turn off the water supply and disconnect the supply tubing at the float
valve. Disconnect the overflow hose at the humidifier.
3. Allow water in the humidifier to cool before continuing.
DANGER:
Scalding is possible if water in the humidifier reservoir
has not been allowed to cool.
4. Turn the petcock (drain fitting) counterclockwise ( ) and drain water
from the humidifier into a bucket.
5. Remove the humidifier from its mounting.
6. Flush loose minerals from the reservoir with water, then gently rub
minerals off the float, heater, reservoir walls and safety float switch. If
mineral deposits have been allowed to build up, steel wool or other
scouring pads may be used.
7. Inspect the valve arm and float for mineral buildup and deterioration.
CAUTION:
If deterioration is noted, replacement will be necessary.
8. Reset the water level. (See Steps 4 & 5 of “Plumbing and Setting the
Water Level”).
