ELECTRODE HUMIDIFIER CYLINDER REPLACEMENT
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 replace-
ment cylinder in stock throughout the humid-
ification season. This will prevent possible
downtime when the humidifier reports cylin-
der end of life.

Turn off power to the humidifier with the external

where the hose is connected to the cylinder.

the steam hose. When free of steam hose lift the
cylinder out.

removed or loosened to remove the cyl-
inder.
