Thanks are due Steve, Mike, and Bill, for spurring me to take a photo for you, Dave. Not sure why the pages supplied by Mike image an apparent Tank Fill handle (if that’s what it’s supposed to be) with “ON” being the vertical position, and “OFF” being horizontal; it’s just the opposite. And the system diagram shows the valve separate from the Manablok. My ‘06 manual’s water pages does not show the same diagram(s). Again, as per the ‘05 manual it’s a case where the coach build changed and they didn’t opt to reprint the manual accordingly.
For a relative owners manual, check the Home menu here above and drill through the Private BAC Members Only area to our Coach Assist section. Water Systems info begins on pg. 177 of my ‘06 Monterey manual. But there is an ‘05 manual there also. Consulting both may be necessary to get relatively correct instruction regarding any one specific component, feature, or procedure.
