Winterizing and Storage
When storing your touring coach, use the same
precautions you would in your home regarding
perishables, ventilation, winterizing, and rain protection�
In addition, for prolonged storage periods, flush out
all the drain lines and waste holding tanks� Also, drain
the entire water system, including the fresh water tank�
Instructions for draining the water system are explained
in the following paragraphs on winterizing�
The primary consideration in winterizing is to protect
the fresh water lines, waste drain lines, waste holding
tanks, hydronic heating and hot water system, and
battery from freeze damage�
NOTE
In very cold weather, winterizing the touring coach
is recommended to prevent damage to the waste
systems.
NOTE
Ram recommends disconnecting the negative
battery cable from the Ram chassis battery for
vehicle storage of more than 3 weeks.
NOTE
Ram recommends any time you store your vehicle
or keep it out of service for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
setting prior to storing. This will ensure adequate
system lubrication to minimize the possibility of
compressor damage when the system is restarted.
Touring Coach Winterization
To perform these steps, you will need an adapter with
an air regulator to connect an air compressor to the city
water inlet, and access to an air compressor� Adapters
are available at most RV stores�
Component Locations for Winterization
Low Point Drain Valve - the fresh water system and
fresh water tank are drained from a single valve� To
access, remove the vent cover from the curbside bed
base�
Water pump - behind the large access panel on the
face of the curbside bed base�
Winterization Valve - behind the large access panel on
the face of the curbside bed base�
Water Service Compartment - roadside exterior;
see
Water Service Compartment on page 6-6�
Instructions for Winterization
1� Level the touring coach from side to side and front
to rear, turn the water pump OFF, and disconnect
the city water�
2� OPEN all the hot and cold water faucets�
3� OPEN the low-point drain valve and allow the
system to drain; see component location this page�
4� Attach the quick connect hose/sprayer nozzle to
the sprayer port (water service compartment)�
Operate the nozzle to drain any remaining water
and then disconnect the hose; see Sprayer Port on
page 6-6 �
5� Allow all water to stop draining and proceed to the
next step�
6� For this step, you will need someone to operate
the toilet foot pedal/flush valve. Using the air
compressor, apply at MAX 50 PSI of air pressure
at the city water inlet (water service compartment)
until no water remains in the system� Operate the
foot pedal on the toilet� You may need to depress
the pedal a few times to work out all the water by
allowing some air pressure to build up between
flushing. Once all the water has been blown from
the system, disconnect the air and continue to the
next step�
WARNING
Do NOT exceed MAX 50 PSI when clearing water
from the system with compressed air. To much air
pressure could damage the system.
7� For this step, have a catch pan or a towel ready to
place under the water pump outlet to prevent water
from running out into the touring coach� Remove
the quick-connect outlet fitting from the water
pump; see Disconnecting the Strainer/Water Pump
Lines on page 9-6�
8� Turn the pump ON briefly to remove any remaining
water from the pump head and lines running from
the tank�
9� Check the water pump strainer to be sure no water
remains; see Cleaning the Strainer on page 9-6 �
10� RECONNECT the water pump if you plan to add
RV antifreeze using the optional steps below�
Otherwise, leave the fittings from the pump
disconnected until the system is ready to be used
again� Best practice: leave a note as a reminder
near the multiplex screen that the water pump is
disconnected�
