Drain And Waste System; Macerator Pump; Macerator Applications - Airstream TOMMY BAHAMA 2017 Owner's Manual

Drain and Waste System

The drain and waste system of your touring coach
includes separate Gray Water and Black Water tanks,
remotely operated electric dump valves for each
holding tank, a macerator pump, and a high pressure
hose with a drip proof valve on an electric reel�
This self contained system enables you to use the
toilet, sink, and wet bath until a suitable disposal facility
is available�

Macerator Pump

The portable waste pump is the ideal solution for
emptying holding tanks on touring coach's and avoiding
dump stations� 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�
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� To retract the hose, press and hold the
retract button while guiding the hose in place�

CAUTION
The waste hose is pressurized when operating the
macerator pump. Secure the loose hose end at the
disposal facility end with supplied inlet adaptors
before turning on pump.
NOTE
Do not run the Macerator pump more than 15
minutes continuously. Do not run the Macerator
pump dry for more than 30 seconds. THE
MACERATOR WILL NOT HANDLE HARD SOLID
OBJECTS, SANITARY NAPKINS OR RAGS. Never
put wet strength paper towels, tissues, or sanitary
napkins in your holding tank. They will not dissolve
and will jam the mechanism of the dump valve
and the macerator pump impeller. Colored toilet
tissue is slower to dissolve than white. Most RV
accessory stores offer tissue designed for RVs that
will completely dissolve.
