SW6 DE Suburban water Heater question

[wado66]

I pulled this image from a thread Herk7769 had. Hope he doesn't mind.
Which side is the 120v and 12v sides?
I have been having issues towards the end of last season with my pop off valve leaking.
It's the Suburban SW6 DE.
After reading thru all of these great threads on water heater issues I have quite a few things I am going to try.

• Already replaced the pop-off valve. No luck.
• As cheap as they are I am going to replace both thermostats. Thought these would be the same but they are not.
• Make sure the tank is properly burped for the air pocket.
• My thermostat cover is in pretty bad shape so I am replacing it.
• Checking my water pressure coming into the camper. Any recommendations on acceptable PSI?

One thing I noticed when I removed the plastic cover over my thermostats, the tank or faceplate over it is not flat. Is the tank designed with a dome shape to it or is it swelling out? I actually envisioned it looking like a typical tank round with domed end caps.
No other visible issues I see that needs to be addressed.
Anyone else have any thoughts on what may need to be checked to try eliminate my water seepage?



BTW: Mine does not show a broken fuse link like the one shown

Do you have pictures of what you're talking about here?

According to the manual, the right asembly is for 110v circuit.

Good luck!

On my unit the left side (black wires) are 120 v ac. The one on the left in the picture is burnt, element is gone.

If you look at manual page 10 it shows black wires 120 v side and red wires 12 volt side in the electrical diagrams.

Mine actually had a whole blown in the disk on 110v side. Make sure you install it tight to the tank. Max pressure would be around 60 to 65, before you blow off your fixtures, most people I know including my self reduce it to 45/50 lbs. It's not your lines as much as the fixtures. If you change them out to home style then you could run at 65 or over even. I bought a rain bird tester, it will tell you what it is at (psi) before you hook -up it cost like 10.00 bucks or so. It could be the left or the right just use a 110v meter and you will know for sure. They DO NOT WIRE ALL THE UNITS THE SAME, even the same brand.

The manual is wrong.....


The left picture shows the reset buttons which can be pressed with the cover in place. The right picture
shows the Hi-Limit/ECO and Thermostat assemblies with cover removed. The right assembly is for the
110V circuit and the left is for the 12V circuit to the LP side of the water heater. Voltage readings may
be taken on the wiring terminals for these devices. Note that the sensor on the right carries 110V AC
and the sensor on the left carries 12V DC.

It is the opposite: left 120 volts ac and right 12 volts dc.

Just changed both of mine to 140° and the 110v was on the left and the 12v on the right in the picture shown.

You just never know do you, can't trust the manuals for crap. I'm going to highjack this thread for a minute please forgive me. But now OC I picked my trailer up today, now the owner wanted to make a deal on the awning poles said he would give 10% over the sale price> I guess you know what I told him...... The monitors wouldn't let me print what I told him.....

I can imagine it was the same thing I would have told him. He had a chance last summer. Too late, D&D is closed for all future fabrications other than the awning attaching brackets for FRF members only.
