this manual. See Page 115 , Nautilus P1 Manual.
Draining and winterizing
If the RV is to be stored over the winter months, the water heater
must be drained to prevent damage from freezing. The water
heater should also be drained and bypassed during the winter-
izing process particularly if introducing RV antifreeze into the
plumbing system.
Draining the Fresh Water System
The low-point drains valves release water in the supply lines by
opening the valves and all faucets. The water heater has its own
drain plug. To drain the permanent fresh water holding tank and
supply lines:
1. Open all faucets, including the outside shower.
2. Open the white fresh water holding tank gate valve.
3. Open red and blue low point drain valves in the outside
utility center.
4. Drain the sink by removing the drain cap.
5. Turn ON the water pump and allow it to run as needed.
6. Make sure the “water heater bypass” valve is set to
“Normal” (horizontal).
7. Relieve the water pressure using the water heater P & T
(pressure & temperature) valve BEFORE removing the
water heater drain plug. If there is any water pressure pres-
ent the water will spray out of the opening when the drain
plug is removed.
8. Remove the water heater drain plug.
When you are finished draining the fresh water system, reverse
these steps and, dump the grey and black water holding tanks
at an appropriate facility or according to local public codes.
After draining is finished, a small amount of water may remain in
the fresh water tank. This is normal.
