Hey guys,
I’m replacing my gas/electric suburban water heater with a suburban nautilus heater.
The rv has orange and white wire connected to each other and a small green wire.
The Nautilus has red black (positive and negative) , orange and blue ( marked LED positive and negative) and two light grey/blue wires marked ODCC

Anyone know how to connect these wires together correctly?
Thanks !

There should have been an installation guide packed with your new heater!

You can download the manual from the suburban website!

Did you label the RV wires as to what went where?
What was the OLD Suburban WH Model?
RV Orange & White connected together????????
2 sources of 12VDC+///house & chassis batteries????



Nautilus
RED ----12VDC+
Black --12VDC-

Orange --12VDC+ to the LED Light
Blue ----12VDC- from LED Light to ground
*with your RV wiring probably NOT used

Grey/blue -----ODCC (On Demand Control Center) From Nautilus Circuit Board


Is it time for your medication or mine?

Thanks!!
Realized yesterday that I need a switch, which is sold separately!
So I’ve ordered the “on demand control Center” and not just the on/off switch (which is also sold separately) [emoticon]
That explains the connectors on the two grey wires (ODCC) and also the two LED wires, these four should connect the the switch.
And I am assuming the red and black wires will connect to the orange/white wires. (Old Biscuit, yes I didn’t mean “connected” , rather orange and white ...positive and negative, sorry about that. Lol
I assume the orange is positive and white negative?
Then there is the small green wire from the RV...don’t know what that is for.
And yes the 120 I won’t be using and I have terminated that into the junction box that was already there.

Orange should be 12VDC+
White should be 12VDC-
**Verify using voltmeter
Green would be GROUND
