How to install an aprilaire 500

Our product reviews and recommendations are researched and backed by real buyers and industry experts, not dictated by our partners. Like any other equipment, it is important to keep up with your seasonal maintenance in order to ensure continued optimal performance. Maintenance is typically performed before each heating season to prep for the coming humidifier season. This maintenance is fairly easy and you can perform it yourself, or if you would prefer, your licensed HVAC contractor can do it for you.

Before you begin any maintenance, your first steps are to turn off the water supply, unplug the system, and turn off the electrical source to the furnace. After you have taken these precautions, you can take the humidifier cover off and check these parts: the water feed tube, the strainer, the orifice, the drain line, and the water panel. With the Aprilaire your automatic humidistat will notify you with a yellow indicator light when it is time to change your water panel.

If you have the M, use other resources to remind yourself when it is time to perform your seasonal maintenance. If you need any or all parts replaced — use the Aprilaire Maintenance kit, part number to get everything you need in one easy kit! You guys think like most engineers that you are qualified due to your PEng degree. However, you always seem to show up looking for help because you can't quite get it or you want a shortcut.

IF you had even looked around this site you may have realized how out of your depth you are in thinking we didn't know the answers to your questions but instead you think your vast knowledge should be left "up" for "others" to try on their own. Are you ready to assume liability if "others" are injured or killed from doing it wrong?

That's why the pros aren't anxious to share their knowledge with "unqualified" DIY engineers or "others". Originally Posted by toocoolforschool.

Use the biggest hammer you like, pounding a square peg into a round hole does not equal a proper fit. You mean know it all? I agree engineers are bad customers simply because we DO understand some of whats going on and we are interested in learning the rest.

I never claimed to know everything about HVAC, hence my asking what the wire designations were. Are you all bitter im stealing your work or what? I just asked for help. It requires replacement to service and repair it. Unplug the humidifier unit, if possible. Turn off the breaker to the unit. Turn off the water supply to the unit.

Disconnect the water line from the solenoid valve by turning the inlet and outlet compression nuts counterclockwise with the adjustable wrench. Slide the compression nuts away from the solenoid valve. Remove the inline strainer in the inlet and the orifice in the outlet of the solenoid valve.

Take note of the positive and negative wiring on the solenoid valve. Disconnect the wire nuts on the wiring and remove the solenoid valve wires from the humidifier wires. Unscrew the mounting bolt from the solenoid valve with the Phillips head screwdriver and remove the valve.

Position the new solenoid valve in the humidifier. Attach the mounting bolt to secure the valve in place. Rewire the valve to the humidifier, and replace the wire nuts on the ends of the wires.

Insert the inline strainer into the inlet and the orifice into the outlet in the new solenoid valve. Reattach the inlet and outlet compression nuts. Turn the water supply on.
