How To Maintain
a Skuttle Steam Humidifier
Because the Skuttle Steam Humidifier is designed to emit mineral-free mois-
ture into the air, the unit should be cleaned and serviced every two-to-four
months during the humidification season. Harder water, colder weather and/or
higher humidistat settings will increase the frequency of cleaning and service.
NOTE
: Some 60-series units (Models F60-1 and F60-2) are equipped with a
Skuttle Automatic Flushing Timer (see page 22), which can reduce mainte-
nance significantly. However, it is still wise for the homeowner to check the
humidifier for mineral buildup every two months or so.
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.
WARNING: Scalding is possible if water in the humidifier reservoir
has not been allowed to cool.

ing timer), turn the petcock (drain fitting) counterclockwise (4) and drain
water from the humidifier into a bucket.
4b. For steam humidifier Models F60-1 and F60-2, use the automatic flush-
ing timer to drain the unit by following these instructions:
A. Press and release the MANUAL button on the flushing timer.
B. Wait 10 to 30 seconds until the flushing noise stops, indicating that
the flushing cycle is complete. (The number of seconds will vary
depending upon how the timer is programmed.)
C. Repeat Steps A and B until the humidifier is drained.
5. Remove the humidifier from its mounting.
6. Flush loose minerals from the reservoir with water, then gently rub miner-
als off the float, heater, reservoir walls and safety float switch. If mineral
