Probable Cause
• No Power.

• ROOM humidity level is
not 3% or more below
SET humidity level.
• Reservoir is empty.
• Float is obstructed.
• SET humidity level is
65%.
• ROOM humidity level
has not reached 1% or
more above SET
humidity level.
• CHECK FILTER (CF)
message flashing.
• Mineral buildup on filter.
• Bottle cap plunger
missing post in bottom of
cabinet
• Dirty filters.
• Air is entering water
bottle.
• Right bottle contains
water.
• This is normal for initial
filling

• Loss of power or a
power failure has caused
the CF message to

Remedy
• Check 120 volt power source.
• Press power button once to
turn on.
• Raise SET humidity level if desired.
• Increase fan speed.
• Fill humidifier with water.
• Free float from obstruction
• A SET humidity percentage of 65%
operates fan continuously. Adjust
SET level between 25% - 60%.
• Continue to run until desired
humidity level is achieved. This
may take up to 48 hours initially.
• Change to a fresh new filter.
NOTE: Local water varies from area
to area and under certain conditions
minerals will build up more rapidly in
the filter.
•Unplug unit for 1-2 minutes to reset
CF function
• Check orientation of bottles.
Reposition so that bottle cap
plunger (stem) is depressed by
post in bottom of cabinet.
• Change to fresh new filters
(HDC12).
•Check "Side-Fill Caps" and valve
assembly caps to ensure tightness.
• Check for leak in water bottle.
• Ensure gaskets for "Side Fill Caps"
are in place.
•The humidifier is designed so that
right bottle empties first.
• Ensure unit is level - Install caster
pads on front casters, as needed.
• Refill bottle for maximum
run time.
•Position unit level. (Some carpet
padding may allow unit to sit lower in
the front than rear with the additional
weight of water bottles in the front of
the cabinet. Install caster pads under
front casters (see page 5).
• Replace filter.
• No action required.
