Scanned Westach Instruction Sheets

Below you will find instruction sheets for a number of Westach's more popular products. These sheets are in 'JPEG' (.JPG) file format.
While containing more information than the simplified instructions found on the 'Wiring' pages, they are somewhat more blurry to view or print, due to their scanned-in format.
Besides looking for your product's instructions below, you should also search for your product in the 'Wiring' simplified instruction sheet pages.
