Bypassing water heater in new SLX

I have found the documentation on my 2017 Jay Flight SLX very confusing. The instructions are very general and leave you guessing: "IF you have a by-pass system installed and IF you have a RV Antifreeze inlet near your pump (which may be under a bed, dinette, sink or island, depending on the model) then you should be able to turn the values on this very generic diagram and suck in antifreeze through the pump..."
Not very helpful at all.
I had to turn the pump on to find it behind panels via the 'aural location' method and so far I've only found two valves at the back of the trailer. So is there another hidden by-pass valve, or does this trailer use the one valve by-pass system???
I'm confused!

I have a brand new Jay flight slx. Wondering if the setup had changed slightly?
Do I turn both of these values? One of them? Should there be a third by-pass valve?

I have never seen that type valve configuration. from the looks of it you can operate the valve tabs toward each other to bypass the water heater but I'm not sure. It's hard to tell without looking at the water heater.

Why not ask your dealer or Jayco?

red - what SLX do you have? Lots of Forum members can assist, but we need info. I concur with Norty about asking your dealer or Jayco, too

Belay my last - I now see it in your profile, sorry. Recommend still, however, you give us info so we don't have to go to the profile.

In your pic is the WH to the left behind the brown wall? The two lines going thru the floor look to be low point drains. The white valve appears to be where the "magic" happens. The black valve below prolly controls cold flow to the WH, looks to be allowing cold into the WH, a turn vertical blocks water going into the WH and allows water to go "up" (to the white valve). White valve, in its current position, is allowing water out of the WH and supplies the TT with hot water. I expect it has a position directing the water from below to the right and blocks flow to the left. Not a clue which position that is other than not the one it's in now.
If it has 4 positions then experimenting should show what each position does.
With the bottom valve in "bypass" and white valve in its bypass position you want water to flow from a faucet with the hot tap open. You won't want water going into the WH, check by draining the WH and leaving the plug out.

Make sure he WH is cool and the pressure is released before removing the plug! (Don't ask ��)

Keep in mind that I'm guessing what the lines and valves are doing. Let the forum know how this progresses.

Black points up, white points down for bypass. They are using 2 3-way valve instead of 3 2-way valves.

Red, hats very close to the setup of my old (non Jayco) tt. Turn the valve handles to point at each other, that bypasses the wh

Thanks very much for your responses. I'll take your advice and see if water comes from the hot water tank when the valves are turned.
(Interesting that the manual does not mention this as a possible by-pass configuration.)
