Maintenance

Sanitizing the Fresh Water Tank

1� Determine the amount of bleach you need for your
tank capacity using the guidelines above� Tank
capacity is listed in Section 4�
2� Pour the bleach into a 1-gallon container and fill it
with water to make a bleach/water concentrate�
3� Set the Water Management Panel selector to City
Fixtures�
4� Connect the hand pump kit to the Water
Management Panel inlet and place the other end
into the container�
5� Pump the concentrated bleach mixture into the
fresh water tank; disconnect the hand pump kit�
6� Fill the tank using a city water connection and
leave the solution in the tank for 4 hours of contact
time to complete the disinfection process� Or, if
doubling the required bleach, 1 hour�
7� Drain the tank, refill from the city water connection,
and drain again� Repeat until the bleach solution is
flushed out.
NOTE
The sanitizing procedure outlined above is in
conformance with the approved procedures of
RVIA ANSI A 119.2 and the U.S. Public Health
Service.

Drain and Waste System

Your touring coach has a drain and waste system that
includes waste-holding tanks made from corrosion-
free, molded plastic, with trouble-free dump valves�
The main (Black Water) holding tank enables you to
use the toilet for several days away from disposal
facilities� The waste water from the sink, shower, bath,
and lavatory drains into the auxiliary (Gray Water)
holding tank�
Each tank has its own dump valve with both tanks
draining through a common outlet� Therefore, only one
sewer hose connection is needed when hooking up to
a dump station�
Almost all campgrounds will have dumping facilities�
Park directories, such as Woodalls and Rand McNally,
also list dumping stations� Furthermore, the navigation
systems GPS can be used to locate nearby dumping
stations or highlight stations along your route�
Check your monitor panel frequently (main Multiplex
control panel or Seelevel monitor)� When the Black
9-8
Water holding tank is completely full, sewage cannot
be emptied from the toilet bowl� If the Gray Water
holding tank is overfilled, drain water will back up into
the shower floor pan and cause an unpleasant cleaning
job� Never drain the tanks at any place other than an
approved dumping station�
Never put wet strength paper towels or tissues
in your holding tank since they will not dissolve
and can catch in the mechanism of the dump
valve. Colored toilet tissue is slower to dissolve
than white. Most motorhome accessory stores
offer tissue designed for RVs that will completely
dissolve.

Macerator Pump

The waste pump is the ideal solution for emptying
holding tanks on touring coach's� The macerator
section grinds waste down to a particle size of 1/8-in�
maximum� The waste pump will macerate and pump all
waste and tissue normally found in recreational vehicle
waste systems�
CAUTION
The waste hose is pressurized when operating the
macerator pump. Secure the loose hose end at
the disposal facility with a supplied inlet adaptor
before turning on pump.
The high-pressure waste hose is stored on an electric
hose reel and connected to the Discharge Port
Adaptor� It has a threaded, drip-proof valve with a
versatile, two-size, threaded adaptor allowing the valve
to be connected to 3 sizes of threaded inlets, including
an exterior home sewer clean-out� The adaptor snaps
over the valve threads� A rubber ring is also provided
to lodge into a non-threaded inlet� If the rubber ring
seems loose when used, Airstream recommends using
some type of weight to further secure the hose�
Each holding tank, the macerator pump, and macerator
pump electric hose reel have individual switches which
are located in the roadside utility compartment� Each
valve switch has a light that illuminates to let you know
the valve is opened� Pressing a dump valve switch and
holding it for 2-3 seconds until it is lit opens a holding
tank valve� Pressing it again for 2-3 seconds closes it�
The macerator pump has an ON/OFF toggle switch�
The reel has a switch for releasing and retracting the
hose, once the hose is released it is deployed manually
by pulling the hose out� To retract the hose, press and
hold the retract button while guiding the hose back and
forth onto the reel evenly�
