I'm researching installation of a humidifer in my home. The Aprilaire 600 specs fit my home but I'm concerned about a note in the literature regarding bypass water to flush the water panel (1 qt/5min or 3 gals/hr).
I don't have a floor drain but use a sump with a pump for furnace discharge. Is the 3 gal/hr only when its in a flush cycle or is it continuous?

It is a bypass humidifer the pad in it should last a couple of years, the water runs over the pad and air pulls moisture off the pad. Putting it into the home. Make sure the damper is open for proper air flow.
Thank you for contacting us regarding the "clunk" sound you are
experiencing with your Aprilaire 550. The noise you have described is called
Water hammer is a pressure surge or wave resulting when a fluid in motion
is forced to stop or change direction suddenly. Water hammer occurs when the
solenoid valve closes at the end of a humidification call.
To prevent the sound of water hammer, we recommend contacting your heating
& cooling contractor to install a "shock arrestor" part number 4280. This
device is installed between the water pipe and the solenoid valve and will
absorb the shock and stop the banging.
Please contact your heating & cooling contractor or our Customer
Service Department if you have further questions.

if it works in the test mode then it should be okay but you can get a humidity gauge from radio shack and set in the house to see how high or low its is. the humidifier is only going to give a max of 45% humidity
You may need a HRV/ERV installed. Depends on your indoor air quality(IAQ). It may be allergies. I would talk to a reputable heating/cooling contractor in your area to evaluate your system, recommendations.
When your unit is on normal the outside unit works and the inside only the fan runs. your heat pump does not remove any humidity when it operates so the installation cotractor did not wire it to operate then. you can change the wiring on the humidifier to operate all the time by wiring it to the fan (g) terminal then it should work just turn it all the way to the lowest humidity when you are in cooling mode.
It is possible you may have wired it wrong. Make sure your humidifer is not robbing power from your thermostat. This would explain when your humidifer makes a demand to come on it robs power from your t-stat making it lose its call for heat. Wire your humidistat to the "w" terminal and the common terminal so it only runs on a call for heat. With the bypass type of humidifier you purchased it wont do you any good to run when the heat isn't running anyway. If you want an independent operation humidifier you need a steam type.
