Macerator Impeller Release Feature

Impeller
Release
Feature
After long periods of non-use, a stuck impeller can
be easily broken loose with a screwdriver inserted in
the motor shaft slot� Remove the rubber boot, turn
the shaft clockwise, and replace the rubber boot� The
impeller can usually be found under the touring coach,
near the macerator hose reel�

Manual Operation

In case the electric dump valves fail to open, manually
pull/push the arm once, to open and close the valve�
The manual arm is located under the vehicle, near the
macerator hose reel�

Extended Stays

When you are in a park with a disposal facility, empty
the tanks every few days or whenever they become
almost full� Pumping a large volume of liquid through
the tanks at a time will keep toilet paper and other
solids completely washed away� Remember to empty
the Black Water tank first and then the Gray Water tank
using the Gray Water to flush the system. This practice
will avoid the accumulation of solids in the tank, which
could lead to an unpleasant cleaning job�
2024 Interstate 19X
Should solids accumulate, fill the tank about half full
with water using the black tank flush inlet, and then
drive the touring coach for a few miles� Don't wait until
the tank is packed solid� The turbulence and surging
of the water will usually dissolve the solids into a
suspension so the tank can be drained� Draining the
tanks as described will protect them from freezing
during storage�

Black Water Tank Flush

Airstream advises flushing the black water holding tank
each time it is emptied to prevent clogging of the water
jets and accumulation of waste solids inside the tank�
Start by emptying the holding tanks at an approved
dump station, close the black tank valve, and leave the
macerator hose connected to the drain. To flush the
tank:
1� Attach a water hose to the flush inlet inside the
macerator hose compartment (do not use the fresh
water tank hose for this purpose)�
2� Turn the water on and monitor the black tank level�
Fill the tank about half full and turn the water off�
3� Open the waste holding tank valve (press and hold
the rocker switch labeled "Black Valve" until the
switch illuminates)�
4� Open the valve at the end of the macerator hose�
Turn the macerator pump ON to empty the tank� As
soon as it is empty turn the pump OFF (running the
pump dry more than 30 seconds can damage it)�
5� Close the waste holding tank valve (press and hold
the rocker switch until the light turns off)� Repeat
this process until the water runs clear, retract the
hose, and lock the compartment door�

Drain System Cleaning

The only cleaning agents that can be used without
causing harm to the system are household ammonia
and tri-sodium phosphate in small quantities� Do not
use any product that contains any portion of petroleum
distillates� This type of product will attack the rubber
seals of your toilet and dump valve� Also, do not use
any dish detergent or abrasive cleaners� All products
should be marked as approved for ABS drain systems
