Where local water may have a high
mineral content, the user may experience a buildup of
scale on some surfaces of the humidifier due to
repeated wetting and drying during operation. This
scaling can be removed by cleaning with household
vinegar or a diluted solution of acetic acid (2 percent by
volume). Perform carefully to avoid distortion of large
copper disc (see fig. 4-27). Rinse the humidifier
thoroughly.
(3)
Make sure all surfaces are clean and that
the motor shaft turns freely by gently turning the small
disc.
(4)
Install humidifier front cover.
c.

as follows:
(1)
Remove humidifier front cover.
(2)
Lubricate the motor bearings every six
months at the two holes in the motor bearing caps using
a few drops of OE-10 (Lubricating Oil, Internal
Combustion Engine). For ease in application an eye
dropper is provided with the humidifier. (See fig. 4-26.)
