Troubleshooting
If the unit does not operate:
• Check that polarized plug is fully inserted into wall outlet.
• Check airflow. Are there any obstructions preventing airflow?
• The motor contains a temperature-limiting fuse. If the motor overheats, the fuse will trip
and shut off the motor. Unplug the unit and contact our Consumer Relations Department.
Do not attempt to repair the motor yourself. Doing so will void your warranty.
If you do not obtain enough humidity:
• It usually takes several uses before the unit reaches maximum output. Continue running
unit to make sure it is operating at top performance.
• Check the water level in the tank and in the water tray. Refilling may be required.
• The unit may need to be cleaned of scale build-up.
If you are obtaining too much humidity:
• If room air is excessively humid (greater than 65% relative humidity), do not use the
humidifier. Excessive humidity is indicated by condensation on cold surfaces or wall in
the room. For proper humidity readings, use a Vicks HealthCheck Monitor available from
Kaz online or select retailers. Other hygrometer models are available in most hardware
and department stores.
• Lower your humidity control setting so that your humidifier will shut off when the desired
humidity level is reached.
If water leakage occurs:
• Make sure unit is unplugged from wall outlet.
• Remove Tank from Base and check Fill Cap. Make sure the Cap Gasket (O-Ring) is
properly positioned in the cap and the Spring Valve operates freely. If leakage still
occurs contact our Consumer Relations Department.
If Fill Cap is too tight:
• Lightly lubricate the Cap Gasket (O-Ring) with petroleum jelly.
