MAINTENANCE AND SERVICING
Required Maintenance
The HM700 humidifier has been designed to require very little
maintenance. Regular maintenance consists of checking the
humidifier to ensure it is in good condition, replacing the
cylinder when the software advises that the cylinder is spent
and cleaning out the drain valve whenever the cylinder is
replaced.
CYLINDER SPENT FAULT
When the cylinder is spent the HM700 will stop operating and
the yellow LED will flash in a repeating pattern of 4 flashes.
See Table 8 on page 23 for more information on other flash
sequences. At this time 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 usage.
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 (see Manufacturer’s Warranty).
NOTE: Honeywell recommends keeping a replacement
cylinder in stock throughout the humidification
season. This will prevent possible downtime
when the humidifier reports cylinder end of life.
REPLACEMENT CYLINDER
The label on the existing cylinder identifies the cylinder type in
its top left corner. When ordering a cylinder always quote the
three or five digit model number on the label, the humidifier’s
serial number and the humidifiers voltage. Serial number and
voltage are located on the specification label on the left side of
the humidifier.
