REPLACEMENT PARTS

CAUTION
Before Servicing
1. Disconnect main power source before accessing
internal compartments.
2. The plumbing and electrical compartments
contain high voltage components and wiring.
Access should be limited to licensed HVAC
professionals only.
3. During and following operation of the humidifier,
the steam components in contact with the steam
such as the cylinder, steam lines, steam
distributors, and condensate lines can become
hot and burn if touched.
4. Installations of humidity equipment installed by
unqualified personnel or the use of non-
Honeywell parts and components will void
warranty.

Cylinder Spent Fault

The yellow cylinder LED will illuminate when the
humidifier has determined that the cylinder is nearing the
end of its life, due to scale accumulation on the electrodes.
The cylinder LED will flash on and off, during which time
the humidifier will continue to operate as normal. After 7
days of flashing, and if the cylinder is not replaced, the
humidifier will shut down and the cylinder LED will be
on constantly (no flashing). At this point, the cylinder
must be replaced.
The steam cylinder is disposable and must be replaced at
end of cylinder life. Cylinder life is dependent on water
supply conditions and humidifier use.
Always clean the drain valve before installing a new
cylinder. Scale from the spent cylinder may have fallen
into the drain valve and could prevent its proper operation.
To properly clean the drain valve, it must be removed and
disassembled.
CAUTION
Equipment Damage
Failure to replace the cylinder at the end of cylinder
life will result in improper operation and may result
in damage to the humidifier. Honeywell is not
responsible for any damages resulting from, or
attributed to, the failure to replace a spent cylinder.
NOTE: Honeywell recommends keeping a replacement
cylinder in stock throughout the humidification
season. This will prevent possible downtime when
the humidifier reaches cylinder end of life.
