Newmar Service Center. If resealing is necessary, it is the owner's
responsibility and is not covered by the Newmar Limited Warranty.

• Wax and buff all gel-coat surfaces on the vehicle as described previously
in this chapter.

Winterizing

To store your unit for the winter months, it is necessary to winterize the water
system to help prevent freezing. To do this, follow these instructions:
1.
The water heater must remain off during this process. Shut off the water
pump and make sure the water supply valves are closed.
2.
To drain the fresh water tank, open the drain valves.
3.
Open the low point drain valves. There is one drain valve for each water
line, one cold and one hot. This is done to drain all of the water out of the
system.
4.
After the water heater has cooled off, remove the
drain plug to drain the water from the water
heater. In the exterior compartment beside the
water heater there are two water heater shut off
valves and a by-pass valve. The shut off valves
must be closed and the by-pass valve must be
open, prior to winterizing to prevent the
antifreeze solution from entering the water
heater.
5.
Close the low point drains to prevent the antifreeze from draining through
the lines onto the ground.
6.
Remove the water filter. See Chapter 7 for more information.
7.
Close the water supply valve that flows from the pump to the tank.
8.
Use only non-toxic antifreeze that has been approved for use in
drinking/potable water systems. Place the in-take hose into the antifreeze
supply. Open the antifreeze valve to allow the solution to flow freely.
Once the water pump is turned on, proceed to the kitchen faucet, bath
faucet, inside and outside shower, turning on the hot and cold, and
flushing the stool until the antifreeze solution flows freely. If the unit is
equipped with a washer, be certain to purge the air from it also. This
forces the antifreeze through all of the water lines and faucets. It also
