Introduction

Thank you for your recent humidifier purchase. We sincerely appreciate your business and are pleased to add your name to our growing list of customers. Now, please take a few minutes and read this booklet. This will familiarize you with the benefits you will receive from the equipment you just purchased and help you understand the routine maintenance that will be required.

I. Principle of Operation

You have purchased a humidifier that operates on the evaporative principle. It will provide the proper relative humidity (see operating instructions) all during the heating season. It is very possible that you have questions concerning what your new humidifier can do for you, and what you should do to receive maximum benefits from it. This booklet is intended to answer these questions.

The humidifier operates in conjunction with the furnace blower motor.

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 humidifier. The water is uniformly distributed across the width of the tray and through a scientifically designed system of outlets. It flows by gravity over the humidifier pad. Dry, hot air is moved through the moisture-laden humidifier pad where evaporation takes place. The now-humidified air carries moisture in vapor form throughout the home.

The correct water flow is determined by an orifice in each humidifier. When the humidifier is operating, there will be a small, steady stream of water to drain, which flushes away most of the

trouble-causing minerals. Do not use the saddle valve to regulate the water flow. It is designed to be completely opened or closed.

The minerals and solid residue not trapped by the replaceable humidifier pad are flushed down the drain. The drain also eliminates the problems caused by stagnant water. This is the most effective and least expensive method to dispose of trouble-causing minerals.

Trouble-free performance and minimum maintenance are assured by the design features of the humidifier. All humidifier housing parts that come in contact with water are non-metal (except for the valve and humidifier pad) and will never rust or corrode. Neither heat nor water will affect them under normal operating conditions.

The humidifier pad, designed especially for uniform, high evaporation, and the Scale Control Insert also efficiently trap mineral deposits which are often the cause of damage to working parts in ordinary humidifiers. No “white dust” can be distributed throughout the living quarters. The humidifier pad must be in good condition to assure high capacity trouble-free performance. It should be changed annually.

Older design water distribution trays have a granular coating in the bottom of the distribution tray to provide equal distribution of water to each of the openings assuring an even flow over the humidifier pad. Do not clean the mineral scale off the bottom of the water distribution tray at

the end of the humidification season. If the granular coating is removed, it is not necessary to purchase a new distribution tray. You can accomplish the same uniform performance by applying a small amount of liquid dishwashing soap over the entire inside surface of the water distribution tray. This will allow the water to flow evenly through each of the openings, provided the humidifier is level, in order to achieve maximum capacity.

The current distribution tray which incorporates a synthetic fabric liner that replaces the granular coating, is designed to deliver water uniformly over the entire top surface of the humidifier pad, provided it is mounted level. It is normal for some mineral deposits to form in the distribution tray as it dries out between humidification cycles. These deposits can actually help distribute water in the tray, but if they form enough to block the openings, they should be removed as described in the “Periodic Preventative Maintenance” section of this manual.

II. Operating Instructions

Your new humidifier is controlled by a Manual Humidifier Control installed either in the living area (typically near the thermostat) or in the cold air return. It is important to anticipate a drop in outdoor temperature and reduce the setting accordingly to avoid excessive condensation. For example, with an outdoor temperature of 20°F the correct setting will be

35% relative humidity. If the temperature is expected to fall to 0°F that evening, then merely reduce the setting to 25% several hours prior to the temperature change.

The recommended settings on the humidifier control are based on years of research (see Table 1) and experience as to what is best for the average home. These settings represent a compromise between RH levels that would be most desirable for comfort reasons and humidity levels that are suitable for protection of your home. For example, a wintertime indoor RH of 50% may be considered ideal by some, but unfortunately, it probably would result in damage to your home.

Observance of the recommended RH levels on your humidifier control, therefore, is an important safeguard. Condensation of water on inside windows in the form of fogging or frost is usually an indication that the relative humidity is too high. This same condensation can take place in other areas in your home with the possibility of damage resulting.

The Humidifier Control is a precision instrument that can be used to determine the RH accurately in your home during the winter. Turn the dial to the lowest setting, then reverse the dial direction slowly until a

“click” is heard. At this point, read the RH on the dial. This will be very close to the actual RH in your home.

To check the humidifier operation, set the humidifier control above the click point, make sure that the water saddle valve is open and that there is electricity to the humidifier. Generally, the furnace and blower motor must be operating for the humidifier control to function. After the humidifier has operated for several minutes and water is entering the humidifier and coming out at the drain, reduce the humidifier control setting below the click point and the humidifier should automatically shut off. Now set the humidifier control dial at the recommended inside relative humidity, depending on the outside temperature. Follow the suggested settings prior to a drop in the outside temperature.

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.

Humidity is lost at an even faster rate than heat because water vapor tends to seek its own level and your humidifier would not be able to replace it even when running at full capacity.

On occasion, indoor moisture producing activities such as clothes drying, cooking, showers, etc., may raise the relative humidity level higher than it should be, even though the Humidifier is not operating.

Telltale indications, again, 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.

III. Effect of Water Characteristics

Your humidifier will operate effectively using either hard or mechanically softened water.

Any type of water (hard, soft, hot, or cold) is acceptable for use with the drain-type humidifiers. Hot supply water, 140° maximum, is recommended for all heat pump applications. The use of hot supply water will also increase the amount of humidity generated in other

applications. The heat in the water increases evaporation and the water going to the drain is cold to the touch. For better performance it is recommended that soft (reduced minerals) or filtered water be supplied to the humidifier pad. This can help reduce the amount of scale and mineral deposits that can accumulate on the pad.

WARNING

RISK OF SCALDING. Water temperature over 125˚F can cause severe burns and scald instantly. Shut off the hot water supply before disconnecting or tapping into any hot water supply line.

IV. Annual Maintenance

For best performance, we recommend that you replace the

Humidifier Pad in your humidifier at least annually. See individual model instructions for additional maintenance.

To purchase a new Humidifier Pad:

• Call the installer of your humidifier.

This information is often found on your equipment.

• Call your heating and air conditioning dealer.

• If none of the above is successful and you still need information, please feel free to contact us at 800-910-9675.

• Purchase only Genuine Source 1 Humidifier Pads to maintain performance.

V. Annual Summer Shutdown

1. For Models 5000 and 6000, close the bypass damper, which is a part of the humidifier, with the use of the small damper handle.

2. Shut off the water supply to the humidifier by fully closing the saddle valve.

Humidifier Control:

No adjustment to the Humidifier Control is required for summer shutdown.
