kohler manual, help w/self install

[gilbyafi]

Does any body have any ideas to get a downloadable version of an owners manual for a Kohler jacuzzi.  This tub is probably 17 years old. Im installing it myself and I wan to make sure that I hook up all the pipes correctly.
Any help would be great.

That is a tough one.  Suggestion, use a shop vac blower to blow into the pipe to identify suction from return.
