    I also need to replace a 760 unit. Is the footprint (dimensions) of the model 700 similar? If so, since the electrical and duct work is already done for the existing unit, why can’t I just simply remove the old on and mount and connect the new one?

    Intent to replace existing model 760
    I have a model 760 (installed 1995) that requires whole unit replacement. My furnace was replaced in 2010 and I assume the cracked and broken mounting is due to heat fatigue.

    I see others have requested info about the footprint and wiring when they go to replace the 760 with the 700, but I cannot see your answers. ?? Can I just remove the old 760 and slip the new 700 in using the same cutout, wiring and water feed??

    Thought my 16-yr old 760 needed replacement when it started making a loud noise. I decided to unplug the unit and dismount the fan housing to examine the fan and motor. Fortunately, the 760 is simplicity itself. I used a Q-tip and grease to lube the motor shaft through the vents in the motor housing and that solved the problem.
    In researching the 760 on the Internet I found an exploded diagram of the entire unit, as well as, many places that carry discounted parts for the 760.
    Replacing the motor (the only moving part) only requires removing 4 screws to separate the housing from the motor mount, removing 4 nuts to release the motor from the mount, loosening 1 lock screw to remove the fan blades from the motor shaft, and 2 spade connectors to disconnect the electrical wires on the motor. 15 to 20 minutes at most and, believe me, I’m an amateur.
    No need to deal with the humidistat, water pad housing, water line and valve, or any electricals, except the 2 spade connectors,
    If you haven’t been replacing the aluminum water pad, the fix may be as simple as replacing a clogged pad (particularly if your water is hard.)

    Aprilaire should have answered everyone’s questions.
    1. The duct opening and water supply for the 700 are identical to the 760.
    2. The wiring is a little different because the older almond color humidifiers have a 24 volt transformer built into the humidifier; therefore, they have their own power. The newer grey color humidifiers require 24 volt power to engage the internal relay which sends the 24 volts to the water solenoid valve and turns on the internal fan. (Found this on Aprilaire’s FAQ, http://www.aprilaire.com/index.php?product=Humidifiers&znfAction=FAQs#10244 .) A 24 volt transformer is included with the 700M, or you may be able to use a 24 volt accessory terminal on your furnace’s block. It’s not a difficult installation, but if you have any doubts, please just have someone help you. It’s not worth wrecking you furnace, your brand new humidifier, or yourself.
    The 700 is still a good unit, made in the USA.

    I am the owner of 3 Aprilaire Model 760 humidifies and have had these units for 15 years. Two of the units are leaking water. I unplugged them, lifted the cover to find the cells are coated with a dark black slim, very disconcerting. These units are monitored and cells/pads are changed every 6 months. One of the units is now just unplugged and not operating. I think its time to change these out and have called my HVAC company to come out. What model do I need to upgrade to? My home is approx 11K square feet, 3 levels.

    Thank you for your question regarding which Aprilaire humidifier model replaces your Aprilaire mode 760. The model’s 700 & 700M replaced the model 760. The plenum opening and water supply line is identical to your model 760. The difference between the 700 & 700M is the 700 includes an automatic digital humidifier control to operate the humidifier, while the 700M includes a manual non-digital humidifier control. The wiring to the 700 & 700M is different than your 760 in that the current models have an external transformer and your 760 had an internal transformer. Your HVAC installer will know the correct way to wire either the 700 or 700M Aprilaire humidifier for your application.

    Thank you for contacting us. I apologize for the issues you were having with your humidifiers. The 800 steam humidifier is the model that I would recommend for your situation, given the square footage of your home.
    The dark black slime that you experienced is typically the result of excessive humidifier run time and inadequately filtered air. The problem can be resolved by replacing the Water Panel, reducing the setting on the humidistat to 35% or lower and ensuring return air to the furnace is adequately filtered. Supplying the humidifier with hot water is a suggestion we would have for getting the most out of the humidifier also.
    To adequately filter the air, we suggest using a filter with higher performance than the standard fiberglass or hogs hair filter. A high efficiency air cleaner, such as Aprilaire®, is preferable.

    Thank you for contacting Aprilaire.

    The current replacement for the 760 humidifier would be the model 700 humidifier. It has the same foot print. Takes the same size opening. If you would like to find an installer in your area, please go to aprilaire.com and use the dealer locator.

    Thank you.
