I just finished hooking up my new he 220a HUMIDIFIER

There is no flow rating because it would depend on too many factors. What you do need to check is the float valve. The water valve is opening and closing like it should be but the reservoir is filling too much.

humidifiers have a drain and if there is water going in it will be coming out the drain. check drain to see if it is clear, check hoses going into top of humidifier for cracks, check filter in humidifier.

Hello, no the humidifier should be running only when the blower motor is running. Sounds like the solenoid valve is faulty if water keeps drainig from humidifier.

I have a Honeywell humidfier HE 220A with a KIP U147112 valve. Will turning the large screw head on the valve decrease the volume of water flow through the humidifier. Too much water is being wasted.

The saddle valve that controls the water is only to be used as an "on" or "off" control. It is not recommended as a throttle valve since it can leak if it is not placed in the full open or fully closed setting

Most installers wire a humidifier to operate when the furnace is calling for heat. To determine if your Aprilaire Humidifier is maintaining proper humidity, turn up the heat temperature 5 degrees above the current room temperature on your thermostat and set your humidifier control to call for humidity. The humidifier control is located on the cold air return duct. To set your humidifier control to call for humidity, turn the control dial to the off position and slowly rotate the dial until you hear a “click” on the control. You should also hear a click at the solenoid valve located on your Aprilaire unit. The humidifier control will have a click point at the current relative humidity level in your home. If the current relative humidity is 45% or the outdoor temperature is above 60F, the control will only operate the humidifier in the test mode.

1. No click at the solenoid valve indicates an electrical problem. Contact your heating and air conditioning dealer to further check the electrical components of your Aprilaire Humidifier.

1. The click sound at the solenoid valve indicates there is electricity to the solenoid valve. By turning the dial of your humidifier control to a setting above the “click point” you should see water coming out of the drain line within a few minutes which would indicate your humidifier is working.

1. If the solenoid valve makes a click sound and there is no water draining from the unit, this would indicate the flow of water is being obstructed.

1. To determine if water flow is being obstructed, turn the dial of your humidifier control to the off position. The first location you would want to check for an obstruction would be at the saddle valve located on the water line supplying water to the humidifier. When checking the saddle valve, you want to make sure it is completely open. This can be done by turning the valve all the way to the left. If anything is clogged, it can be dislodged by turning the saddle valve all the way to the right and back to the left. Once this is done, turn the humidifier control dial above the click point and you should see water coming out the drain line.


If water is still not coming out of the drain, check the orifice and in-line strainer to make sure they are not clogged. The orifice is located in the tube on the discharge side of the solenoid valve and the in-line strainer is located on the inlet side of the solenoid valve. You may clear the orifice by inserting a needle through the small opening. Clean the strainer by running it under warm water to dislodge deposits or replace. After clearing and re-installing the orifice and strainer (be sure to double wrench all water connections), turn the humidifier control dial above the click point and you should see water coming out the drain line.

push sail switch forward by hand to see if that is the problem.
Remove two wires at humidifier and connect them if it starts than it is in wiring, humidistat, or transformer.

A small discharge of water coming out of the bottom of an April Aire drain spud is normal. This feature constantly tries to rinse the system. This helps to prevent the possibility of mold or bacteria accumulating in the unit from standing water. It may appear to be alot of water. But be reassured that you are breathing in cleaner air. Now if it continues to drain constantly even when it is turned off then you should repair the unit.

Hi, Hot will make the problem worse. If your calcium is that high you will have scale in your tubs, sinks and toilets. Calcium is a pipe clogger and if you have noticed this type of scaling you may be wise to consider a whole house water filtration system, it will save you lots of problems in the long run. Good Luck!

water trough on top filling up. do not clean it too much as crud distributes water across top better.
