Water Heater Bypass Valve; Winterizing Procedures - Winnebago Itasca Ellipse Owner's Manual

WATER HEATER BYPASS
VALVE
-If Equipped
(Not available on Models 40CD and
42AD)
Your coach may be equipped with a water
heater bypass valve for easier winterization of
waterlines using RV antifreeze. See Water
System Drain Valve Locations chart at the end of
this section for valve location on your model.
Turn the handle as shown to either Bypass or
Normal flow through the water heater.
Leave bypass valve handle in NORMAL
FLOW position if draining water and blowing
out waterlines. Place in BYPASS position ONLY
when using antifreeze solution in waterlines.

WINTERIZING PROCEDURES

You can winterize the water and plumbing
system of your coach using one of the following
two methods – 1) Blow out waterlines using
compressed air or – 2) Fill waterlines with RV
water system antifreeze.
Method 1 – Blow Out Procedure
(Drain and purge waterlines using
compressed air)
This procedure is NOT to be performed
with coaches equipped with the Aqua-
Hot Hydronic Heating System!
NOTICE
Do not blow out Aqua-Hot hydronic
heating system. Failure to comply may
result in system damage.
1. Level the Motor Home. If the coach is not
level, there may be "low points" in waterlines
that can trap water in the lines and prevent it
from draining properly.
2. Drain Fresh Water Tank and Waterlines.
Open all waterline drain valves and drain
fresh water tank. (See "Water System Drain
Valve Locations" chart at end of this section
for locations of drain valves on your model.)
3. Drain Exterior Shower/Wash Station.
Open exterior shower knobs and lay shower
head on ground as shown to drain any water
left in the shower line. Also place the tip of
your finger into the city water inlet and gently
press the backflow valve "button" in the
center of the inlet to drain any water trapped in
the inlet line.
