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.
POISON
Use only non-toxic FDA approved RV
antifreeze that is specifically made for
potable water systems. Automotive
antifreeze, if ingested, can cause
blindness, deafness or death.
Using Air Pressure For 38 PKQ
Access to an air compressor and an adapter
to connect the air line regulator to the water
system is necessary. Air adapters used for
winterization are available at RV supply
locations. Air pressure SHOULD NOT exceed
40 PSI. Higher pressure can damage the lines.
WARNING
It is recommended that a qualified
RV service technician familiar with
motorhomes, such as an authorized
dealer, perform the winterization
procedure.
NOTE
Freeze damage is not covered under
warranty.
1. Empty and flush the holding tanks.
2 Disconnect the water line connections

WARNING
Ensure the water is not hot when

lines. Hot water from the lines can
burn or injure skin.
6. Turn the water pump on for 30 - 60
seconds and allow it to run so that all
the water is cleared out of the water
pump and fresh water tank.
7. Turn the pump off.
8. If applicable, disconnect water line to

Some appliances such as the
