Need help getting info for older sears whole house fan model#758642301

​​​​​​​​​​​​​​​​​​​​​​​​​​​I bought this whole house fan on CL for $50 it’s new never been installed. Tried looking up the manual on a website but it’s been discontinued. I just wanted some installation info since it’s not like new ones where it’s all one unit, parts are separate the motor and fan blades are not mounted to the shroud. So how far should blade tips be top of shroud? And is motor variable speed, 2 speed or 1speed. Any thoughts or help be great I’m new to forum so not sure I’m doing it right and if I can load pics or not anyway thanks here’s part #s it’s a Sears whole house fan model 758.642301. Motor is an Emerson model #KA55HXGEW-1722

Welcome to the forums.
I moved your thread to the fan forum.

That fan was manufactured by Emerson Electric
The motor won't be variable but it may be two speed. It should be right on the motor.

Feel free to post pictures.... How-to-insert-pictures

Older? How old do you think it is? Is it a belt drive or direct drive? Emerson's Whole House Fans were all direct drive by the early '80s. If it's an older belt drive fan it's most likely a 2 speed motor, the diagram on the motor should tell that tale. You could still use a variable speed motor control if you wire it to the high speed. Emerson private labelled their fans with the Sears name for many years, just like they did for shop vacs, disposers, hot water dispensers, weed whackers, chain saws and even power saws.


If direct drive, this might be of some assistance to you and be a source for a speed control.
