Cold Weather Storage; Winterization; Using Air Pressure - Fleetwood Discovery Owner's Manual

Cold Weather Storage

If the motorhome is stored where
freezing temperatures may occur,
drain the fresh water system.
Begin draining the fresh water tank
and allowing the water to drain.
CAUTION:
Icemakers, water filters,
and water heaters all use
the fresh water tank for
water. These systems should
be drained
and stored in
accordance
with the OEM
recommendation for
winterization. Consult
specific OEM manual
for instructions and
recommendations.

WINTERIZATION

Water, plumbing and sewer
systems require winterization
when the motorhome is placed in
storage. The recommended method
of winterizing the motorhome
is using air pressure to remove
liquids that may freeze and cause
damage to the various systems and
appliances. The lines can then be
left empty or filled with an FDA
approved RV antifreeze.
When plumbing lines are
drained, antifreeze is not necessary
and the decision to use antifreeze
is left to the motorhome operator.
WARNING:
Freeze damage is not
covered under warranty.
CAUTION:
It is recommended that
a qualified RV service
technician familiar with
motorhomes, such as an
authorized dealer, perform
the winterizing procedure.
WARNING:
Turn off the Aqua-Hot
and allow it to cool before
beginning the winterization
procedure. Hot water can
result in burn injuries.
NOTE:
Some items (optional and
otherwise) such as the
Aqua-Hot, icemaker and
washer-dryer require
individual winterizing
procedures. Refer to
all OEM manuals for
winterization instructions
and procedures.
POISON:
Use only non-toxic FDA
approved RV antifreeze
that is specifically made
040460p
for potable water systems.
Automotive antifreeze,
if ingested, can cause
blindness, deafness or
death.

Using Air Pressure

Access to an air compressor
and an adapter to connect the air
pressure regulator to the water
system is necessary. Air adapters
used for winterizing are available
at RV supply locations. Air
pressure should not exceed 40 PSI.
Higher pressure can damage the
lines.
1. Empty and flush the
holding tanks.
2. Drain the fresh water
tank by opening the drain
valve located in the water
service center behind
termination valves.
3. Open hot and cold low-
point drain valves. Open
a faucet to break vacuum
and let water drain.
