CHECK THE HUMIDIFIER OPERATION
Turn the control knob to the maximum RH setting . Make sure that the
water saddle valve is open and that the humidifier is on . The indoor unit
blower must be running for the humidifier to function . Once humidifier
operation is verified, reduce the Humidifier Control setting to the
recommended inside humidity, depending on the outside temperature .
If using the automatic humidifier control model number
KUAWC0101COR, DO NOT LEAVE IN TEST MODE AS HUMIDIFIER
WILL NOT OPERATE.
ADDITIONAL INFORMATION
Be sure to keep fireplace dampers closed when not in use . They provide
an excellent escape route for heat, as well as humidity .
On occasion, indoor moisture producing activities such as clothes drying,
cooking, showers, etc ., may raise the humidity level higher than it should
be, even though the humidifier is not operating . Telltale indications are
condensation or frost on cold surfaces such as windows, doors, walls,
etc . If such condensation persists for several hours, your home should be
ventilated to dissipate the potentially damaging excess moisture .
