Replacing an existing Aprilaire model 760 humidifier, couple of questions...

Monday, February 4, 2013 by Aprilaire Team
Consumer question:
I want to replace the existing 760 model, however, due to the size to the furnace, it cannot be any larger than the existing unit. The current model 700 is about 2 inches higher so I can use it. What model would you suggest I use and what if any issues will I run into.
Aprilaires' response:

Thank you for contacting us regarding the replacement for you model 760 humidifier. If you are unable to replace the 760 with the 700 then you could use the model 600. The 600 is a bypass humidifier which operates slightly different than the 760 or 700. Where the 760 and 700 are power humidifiers that use an internal fan to add humidity to the air in the duct work, the 600 is a by pass unit that utilizes the HVAC blower to add the humidity to the air.

The 600 has similar capacities to the 700 and can provide humidity on a tight home with 8 foot ceilings of up to 4000 square feet.

Additionally, due to the differences in the installation, as well as the wiring of the humidistat control, we recommend the installation be done by a licensed HVAC contractor. When installed by a licensed contractor, the units come with a 5 year warranty beginning on the date of installation. If you choose not to use a licensed contractor you risk voiding the 5 year warranty.

If you have any further questions regarding this or any of our products, please feel free to contact our customer service department at your earliest convenience.

I need to do the same due to the squeaking sound coming from the unit. Can I just replace the motor or is there another fix. The unit itself is fully operational.

Thank you for your inquiry regarding the operation of your model 760 Aprilaire humidifier. It appears form the sound you described the bearings are starting to wear out in the fan motor, our part number 4237. This is something which your HVAC installer can replace and the unit will be back in proper working condition. We ask for you to please contact them to arrange the replacement of the fan motor.

Thank you for giving us the opportunity to be of assistance.
