Sanitizing the Fresh Water System
Sanitize the fresh water system before initial (first time) use,
after extended periods of motorhome storage, at least every 6
months during continuous use, or if the fresh water system,
fresh water supply, or fresh water holding tank has been com-
promised or contaminated.
1.
Remove or by-pass the potable (drinking) water filter (if
equipped).
2.
Prepare a sanitizing solution of one gallon (3.78 l) of water
and ¼ cup (2 oz/60 ml) of liquid household bleach (5%
sodium hypo-chlorinate solution). You will need one gal-
lon of solution for every 15 gallons of fresh water holding
tank capacity.
3.
Empty the fresh water holding tank.
4.
With all faucets and drain valves closed, pour the solu-
tion into the fresh water tank, via the gravity fill port. Or,
carefully pour 1/4 cup (2 oz/60 ml) of bleach for every
15 gallons of fresh water holding tank capacity into your
potable (drinking) water hose before connecting it to an
external water source. Open the external water source
valve. The water source pressure will push the chlorine
and water into the fresh water tank, making the correct
dilution when the fresh water tank is full.
5.
Completely fill the fresh water tank with fresh water and
close the valve on the external water source (if connected
to the city water fill port).
6.
Switch ON the water pump. Open all the faucets one at a
time until all air is purged, and the water begins to flow;
then close the faucets. This ensures the water lines are
filled with sanitizing solution.

7.
Top off the fresh water tank until the water level reaches
the overfill spout. Turn OFF the water pump.
8.
Allow the solution to stand in the fresh water system for
at least three (3) hours.
9.
Drain the fresh water system by opening all faucets, fresh
water tank drain valve, and low point drain valves while
flushing the system with fresh potable (drinking) water.
10. Continue flushing the system, allowing the water to flow
for several minutes.
11. Close the fresh water tank drain valve and the faucets.
Refill the system with potable (drinking) water.

Winterizing the Water System
WARNING
WARNING
Automotive antifreeze (ethylene glycol) and windshield
washer antifreeze (methanol) are poisonous. Never
use these products in your fresh water system. These
products are harmful and may be fatal if swallowed.
Only use biodegradable RV antifreeze to winterize your
motorhome's fresh water system.
NOTICE
NOTICE
Do not add antifreeze to the water heater. Antifreeze can
be damaging to internal components of the water heater.
For proper water heater winterization, drain the water
heater tank AND bypass the water heater inlet before
adding antifreeze to the fresh water system.
IMPORTANT! Read and follow the manufacturer's instruc-
tions for winterization of the furnace/water heater. These
instructions also include important safety and maintenance
procedures for the unit.
Preparing for colder weather or storage is an extremely
important part of routine motorhome maintenance. The
motorhome should be winterized at the end of the camping
season, or when exposed freezing and below freezing tem-
peratures (32°F; 0°C). Repairs due to freezing liquids are not
covered by warranty. Add only RV antifreeze to the fresh
water system to ensure freeze protection. It may be easier to
winterize the motorhome with another person assisting you.
1.
Level the motorhome by parking on a level surface.
2.
Turn OFF the furnace/water heater switch on the controller
or multiplex panel.
3.
Turn OFF the main gas valve (solenoid) and at the fur-
nace/water heater (if a second valve is installed).
4.
Drain the fresh water plumbing system by opening all
low-point drain valves, fresh water tank drain valve, and
drain the tank of the furnace/water heater.
Refer to the water heater manufacturer's instructions for
winterizing procedures.
5.
Remove or by-pass the potable (drinking) water filter (if
equipped).
6.
Turn the water heater bypass valves (if equipped) to the
BYPASS position. DO NOT ADD ANTIFREEZE TO
THE WATER HEATER.
7.
Close the low point drains.
8.
Attach a hose to the city water fill and insert the other end
