    I did not need to order the entire Maintenance Kit, as I only needed to use the new filter. The new filter has made a big difference. Replace yours today. B

    It's always a good idea to get the original for the original piece of equipment. Tried other junk and had leaks. Not a problem with this kit.Found out that installer broke a small hose, and I was able to correct it with this kit. GREAT Value.THANKS.

    When the Maintenance Kit arrived, the scale control panel in the box was broken. (Better packing probaly could have prevented it.) One phone call to customer service, and a replacement was on the way. No questions asked, and no shipping the broken part back to Aprilaire! The new panel arrived in only two days.

    Water started leaking from my Model 600. After some investigation, found out I should have replaced the filter unit some time ago. Decided to buy the maintenance kit as recommended. I received the kit when promised, directions were great, and install of parts took minutes. Unit is back on line and working like new. Went to Aprilaire site specifically to make sure I didn't receive 3rd party parts made in China.

    Easy to order with online help. Installation was made simple with the enclosed instructions. My first time ordering and installing and everything went without a hitch. Humidity has improved greatly since installed. Would recommend Aprilaire humidifier and replacement parts.

  • Would of been five stars

    01/02/2013

    Every thing in this kit is what you need to do maintenance on your duct dehumidifier ans instructions were very clear. I would have put five stars but top panel had its corner damaged in shipment, although didn't seam to make any difference in the way system works.

    I ordered parts for my Aprilaire humidifier and discovered when I read the instructions for installing the product that the original part put in place by the HVAC company was the wrong part. Thanks for the great instructions included with this maintenance kit. I haven't installed it yet but will in a few days. I look forward to better humidity in home this winter. I always like to get genuine replacement parts for all of my equipment. Thanks for great instructions and great service.

    02/02/2012

    The kit came quickly and would have been easy to install had the initial installation not been botched. After some trial and error, I was able to get everything to work. My only complaint on the kit is that the rubber tube is too stiff. A tube that is a little more flexible would be easier to install.

    Except for page 13 of the Owners Manual, there is no mention that the end of the water feed tube with the orifice connects to the solenoid valve.

    Bought a house w/ an aprilaire humdifier. On inspection it looked like it hadn't been serviced in a while and it wasn't working (they had it hooked up wrong). Bought this kit and replaced the main components. Very easy. Took about 10 minutes. System working well now. No longer need separate humidifier in young son's room.

  • Simple Replacement

    Posted by: Larry G

    11/06/2011

    Only one suggestion. The water tube could be more flexible. Other than that, replacement went well.

  • Panel installed easily, tubing not

    Posted by: michigan home owner

    02/01/2011

    I ordered a maintenance kit to replace the water panel that had become moldy. It was easy to install and works fine. The replacement tubing was impossible to put in. I left the old tubing in. Things are working fine, but the uninstallable parts are a waste.
