Tuesday, December 20, 2011 by John:: 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?

Sunday, December 2, 2012 by J. Cabiness:: 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.
Monday, December 10, 2012 by Ed Szostak:: Please be clear, 1999 Model 760 heat fatigue will the model 700 fit correctly?
Please just answer the question.
Wednesday, December 19, 2012 by Rusty:: 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??

Friday, January 4, 2013 by Ron:: 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.)
