Introduction

The benefits of a properly humidified environment (35-50% Relative Humidity) are many. They include both personal comfort as well as the preservation of furniture, draperies, carpets, wooden floors and cabinets, paintings, pianos, etc. Your home can be more comfortable at a lower temperature (i.e.: 68° F) at 35-50% Relative Humidity (RH) than at 71° to 72° F without controlled humidity. Since every degree of temperature setback represents about 3% of your heating costs, this can possibly represent a significant annual savings. During the heating season, cold air infiltrates the home and must be heated. When heated, this air dries out and greatly increases its capacity to hold more moisture. By using a humidifier, a source of water is provided to satisfy this increased moisture holding capability, rather than having it drawn from our body surface and the surrounding furnishings in the home.

DO NOT install the humidifier where freezing conditions could occur or where accidental overflow could cause water damage to the home or property.

For any installation in areas where water damage could occur,

always install a drain safety pan, plumbed to a suitable drain.

Output Capacity

Increasing or decreasing the nozzle size or supply water pressure can vary the output capacity of this humidifier. It is recommended that the humidifier NOT be used with water pressures below 40 PSI, otherwise, the mist may be adversely affected.

This humidifier comes standard with a .75 GPH (oil) nozzle with a hollow spray pattern. Alternatively sized nozzles may be purchased from your local HVAC supply house or plumbing supply outlet. If the water pressure fluctuates or is excessive, a pressure regulator should be installed in the water line supplying the humidifier.

The following chart illustrates the capacity of different nozzles at varying water pressures. The capacity listed on the nozzle is for #2 fuel oil at 100 psi and should not be considered relative to the water capacity of this humidifier.

Installation

When selecting a location for the installation of your humidifier, certain conditions must be met for its proper operation. The recommended location for this humidifier is on the warm air supply plenum, approximately 3 inches downstream of the furnace discharge. The air temperature must be at least

120ºF in order for the temperature switch to operate properly. In narrow plenum/ duct arrangements, the humidifier should be mounted on the narrow side of the duct. Select a location so that the spray from the nozzle will not impinge on the furnace fan, control switches, air conditioning or heat coils, or walls of the duct.

The humidifier should be mounted so that the furnace air carries the mist away from the humidifier temperature switch. The direction of airflow is indicated inside of the humidifier housing and on the rating label on the side of the humidifier.

DO NOT install the humidifier where freezing conditions could occur or where accidental overflow could cause water damage to the home or property.

DO NOT install the humidifier where the temperature will exceed 180°F.

Excessive heat may cause softening and distortion of the plastic housing.The installation of a water filter may reduce the potential clogging of the nozzle and solenoid valve in hard water applications.

I n s t a l l a t i o n , O p e r a t i o n , & M a i n t e n a n c e M a n u a l

Operation

Overview:

Your atomizing mister type humidifier operates by dispersing a fine mist into the warm air plenum of your furnace. The water is then evaporated and carried into the home by the furnace air flow. This humidifier is recommended for areas where water mineral content is low. Otherwise, a fine accumulation of white dust may occur in either the ducts or living areas. High mineral content will also clog the nozzle causing an uneven spray pattern, excessive dripping, or total blockage of the nozzle tip. When wired properly, the humidifier will operate only when the plenum temperature rises to the internal thermostat setting, the humidistat senses a need for humidity, and the furnace blower is in operation. The internal thermostat controls the temperature at which the humidifier will turn on. The humidifier should activate after the furnace blower comes on and shut off before the furnace blower turns off. If this does not occur, readjust the furnace fan switch as required. If applicable, set the humidistat in the recommended range of 35-50% Relative Humidity for automatic humidity control during the heating season (a lower setting may be used to control condensation on single pane windows). Due to the operation cycle of the furnace and humidifier, it may take two to five days to reach the proper humidification level.

Start-up & Operation:

1. Adjust the humidistat to the ON position and turn the furnace on.

2. Adjust the house thermostat to cause the furnace to operate. The heat and blower should turn on BEFORE the humidifier.

3. The solenoid valve will make an audible click when it operates, either on or off.

4. If necessary, adjust the furnace fan control to a lower setting to allow the blower to turn on before the humidifier turns on and the blower turns off after the humidifier is off.

5. Readjust the humidistat to the desired setting (35-50% Relative Humidity is recommended).

6. If condensation occurs on windows, lower the humidistat setting until the condensation has disappeared.

Maintenance

Like your heating system and air conditioning unit, periodic maintenance and cleaning are required to ensure the safe and efficient operation of your humidifier. To improve the efficiency of your humidifier, and to reduce the possibility of a health hazard, it is recommended that you take the following precautions:

• Follow the manufacturer’s recommended cleaning and maintenance instructions.

• The amount of minerals and other impurities in a water source can vary greatly, therefore the frequency of cleaning the humidifier also varies.

• During the heating season, check for film or scale build-up on the atomizing nozzle on a monthly basis. Establish a proper cleaning schedule to ensure the efficiency of the humidifier.

• At the end of the winter humidification season, drain and thoroughly clean the humidifier.

NOTE: The necessity to clean your humidifier is substantially the result of impurities coming in through your water supply which feeds the humidifier. Other household dust, containing biological and microbial contaminants can find its way into the air handling system and ultimately, the humidifier. The humidifier is not the source of these impurities.

To clean and inspect the unit:

1. Turn the power to the furnace OFF.

2. Turn the humidistat to the OFF position.

3. Turn the water off at the saddle valve and remove the water tubing from the humidfier.

4. With the open end of the water line directed into a bucket or pan, turn on the water at the saddle valve to void the water line of any debris or particulates.

5. Remove the screw securing the unit cover to the housing and swing the cover down to gain access to the nozzle.

6. Carefully remove the nozzle from the adapter and proceed to clean the spray nozzle section.

7. Replace the spray nozzle with a clean one or new one of the same size and capacity as initially provided with the unit. Use care and secure tightly.

8. Swing the cover into place and fasten with screw.

9. Restore the water supply to the humidifier by reversing step 3.

To check for leaks:

1. Turn the furnace and humidistat on and ensure that the humidifer has operated for at least one minute.

2. Remove the screw securing the cover to the housing and check nozzle for leakage.

3. If there is no leakage, return the unit to its original position and secure with screw.

4. After completing the cleaning, operate the solenoid to be sure it's operating properly.
