I realised you wanted
de-winterising procedure- so basics are:
1) connect to city water w/ pressure regulator- energise system
2) open low point drains on outside, just aft of LP fill valve, under body
3) purge until clear water comes out, close low point drains
4) open black & grey tank gates and cap, place tub under to catch
5) open taps starting at rear, flush toilet, showerhead, rear sink faucet, front sink until clear.
NOTE: Don't forget the rear spray, behind RR cargo door!!
6) open low point drains again until clear.
Fresh tank system:
7) Remove rear (side) panel in pass. side bed storage compartment, to find AF riser tube and fresh tank valve on dec behind panel (see pic- no need to remove bed support top- just lift hinged section)
8) Disconnect from city and reconnect to water fill (fresh tank) and fill tank 1/2 full or more
9) Open fresh tank valve (behind inner compartment wall of storage under pass. bed), rear of tank, on deck. Be sure AF riser is capped!
10) purge fixtures as before- Run until clear, and air is out.
11)Close PRT (yellow lever) valve, open H&C supplies to Truma, and close bypass. Open PRT valve for a few minutes, then close, then go to taps and open taps for hot water until air is out.
NOTE: if you want to sanitise fresh tank, close off Truma as it has sensors that can be damaged by Chlorine. Add 1/4c to tank and run thru all taps until you smell it- then let sit for 24hrs. Flush out after, make sure it's all out before re-opening the Truma.
If weather gets cold (at or below 32°F), open all compartments and use a small 750W space heater inside and keep at 50°F min. and be careful where you place and aim it!! OK to be plugged into shoreline to enable battery heaters.
Battery heaters will come on at 32° to keep at charging temps. 23°F is min. temp for storage for the ReLion batteries otherwise.
The Truma furnace/water heater can be used as a heater w/o water when bypassed. Just turn LP switch on (outside near LP fill valve) and use Truma control to turn on- read Truma manual- it takes some getting used to...
Final note- while doing all this- look and feel for leaks!!
Thor uses a lot of swivel fittings and can leak of too tight- rule is hand tight + 1/4 turn for those. If leaking, depressureise system and back off fitting, let relax for awhile, then re-install.
Electrical is also something to check- opposite problem from factory- too loose and arcing, so inspect all points for blackening, or loose terminals, including underneath at the batteries, buss bars, and components that they left under there for some stupid reason. I moved all mine up inside last year. Much easier to inspect and maintain. I have a pdf on that too... :-)
