INTRODUCTION
Thank you for your recent purchase of our humidifier. The addition of this product to your heating and cooling system will increase your level of comfort by adding just the right amount of moisture to your indoor environment. During the heating season, your humidifier will not only make you feel more comfortable, but it will help protect your home and your furnishings, as well.
Your new humidifier is easy to use and easy to live with. Simple maintenance is required on a periodic basis to keep it in peak operating condition. This homeowner’s manual will outline these steps for you, as well as other basic operating procedures so you can enjoy the full benefits of your new humidifier.
How Your Humidifier Operates:
During the winter, your comfort relies on two things: the perfect temperature and the perfect amount of moisture. Your new humidifier will provide your home with the recommended indoor relative humidity to ensure your comfort all winter long.
Replacement Humidifier Pads are available from your installing dealer.

I. YOUR HUMIDIFIER
Your new humidifier has been installed to operate in conjunction with the blower motor in your furnace. When the Humidifier Control calls for humidity and the blower motor is operating, water flows to the distribution tray located at the top of the unit. The water is evenly distributed across the width of the tray and over the Humidifier Pad. Dry, hot air is moved through this moisture laden Humidifier Pad where it is evaporated into a vapor. This now humidified air is circulated throughout your home. Humidified air helps to reduce static electricity, reduces wood furniture from drying out, helps prevent nasal passages from becoming too dry and makes your home more comfortable.
Important Notes About Your Humidifier:
When the humidifier is operating, there will be a small, steady stream of water to drain. Do not use the saddle valve to regulate the water flow. The saddle valve is designed to be either completely open or completely closed.
Although your humidifier incorporates a self-flushing action, the Humidifier Pad will develop mineral build-up on it over time. To assure high capacity, trouble-free performance it should be replaced annually.
The granular coating on the bottom of the distribution tray is designed to provide an even flow of water over the Humidifier Pad. Do not clean the mineral scale off the bottom of the distribution tray at the end of the humidification season. The scale actually provides an excellent track for the water to follow.

II. OPERATING INSTRUCTIONS
Models HUMD300A and HUMD500A with Automatic Humidifier Control: (Manual Humidifier Control-see pg 4)
Your Automatic Humidifier Control is installed in the cold air return. During the first heating season, your Automatic Humidifier Control needs to be set initially to match your home’s condition. Please follow these steps when adjusting your control (refer to Figure A).
1.Turn the dial setting knob to “5,” which is within the normal range. During the next 24-48 hours it may be necessary to adjust the dial for more or less humidity, depending on your personal comfort and home’s requirements. Refer to the “Operation Guide” (Table 1).
2.During the coldest portion of the first heating season, minor adjustments may be necessary. This is dependent upon your individual home construction, refer to the “Operation Guide” (Table 1).
