Most coaches with Smart Beds had no HWH valve schematics. I think that WRV was waiting to get them fixed, see note below.
Thanks to Hugh Reed aka hrhuggie, for suppling this photo. I doctored it up a bit to make it more legible. I have sent a larger copy of it in to the ACA website, for your use.
The numbers on the drawing refer to:
# 1 is drivers side front.
# 2 is drivers side rear.
# 3 is passengers side rear.
# 4 is passengers side front.
This applies to slides or Smart Beds (bays.)
The bottom diagrams are for the solenoids that are under the coach behind the water tank. The right diagram is backwards, the one on the left is correct. I did not check all of the extend and retract, but some of mine work backwards. My bay 3 & 4 were swapped also, which I corrected.
As you can see, if you have a failure in the valves accessed thru the Smart Beds, you can still open #3 manually or with power and get to them.
