3. Place the plastic
termination
fitting
over the
motor
home drain
outlet
and secure
by
turning
the
fitting
firmly
clockwise.
Be
sure
the
clips
catch
firmly
to hold
the
fitting
in place.
4.
Insert
the
opposite end
of
the
sewer hose into
ground sewer or
dump
station
inlet, pressing
it
firmly
far enough
into
the
opening
to
be secure.
In some cases, adapters
may
be
necessary
between the line and
the
inlet. Arrange the sewer
hose so
it
slopes evenly.
5.
Dump the black water holding tank first. Unlatch
the
black water knife valve (the large one)
by
removing
the
wire clip
or
unscrewing
the
lock
nut. Grasp
the
handle
firmly
and slide
the
valve
open
with
a quick, steady pull.
6.
Allow
sufficient
time
for
the
tank
to
drain
completely. Rinse and flush
the
tank through the
toilet. When
the
tank
is empty, push
the
handle
inward
to
close
the
valve. Reset
the
locking
device. Even
if
you are parked
at
a site
with
a
semi-permanent sewer
hook-up, close
the
black
water
knife valve
to
allow
the
waste
to
build
up.
The
outlet
will
probably
clog
if
you leave
the
knife valve open continually. Run enough
water
into
the
tank
to
cover
the
bottom.
This
will
aid
the
break up
of
solid wastes.
7.
To
dump
the gray
water
tank, repeat steps 5 and
6
for
the
small knife valve. This
tank
is dumped
last
to
aid in flushing
the
outlets
and hose. The
gray water knife valve may
be
left
open in a semi-
permanent hook-up.
8:
Remove
the
sewer hose and replace
the
cap.
g. Rinse
out
the sewer hose
with
a fresh water hose
or
other supply and remove
the
sewer hose from
the
dump
station.
10 Store
the
sewer hose and replace sewer
or
dump
station
covers.
PLEASE . . .
USE
GOOD HOUSEKEEPING WHEN
DRAINING WASTES
AT
A CAMPSITE
OR
DISPOSAL
STATION.
LEAVE
THE SITE
IN
GOOD
ORDER.
ABOVE
ALL,
DO
NOT POLLUTE.
Holding
Tank
Care
and
Maintenance
Since
the
holding
tanks
don't
rely
on any
sophisticated mechanical devices
for
their
operation,
they
are
virtually
trouble-free. The
most
common
problem is also
an
unpleasant one - clogging.
You
can minimize the chances
of
clogging
by
keeping the
following
considerations in mind:
24
o Keep
the
black water
tank
knife valve closed. Fill
tank
to
at
least
3/4
full before dumping.
Be
sure
to
cover
the
tank
bottom
with
water
after .
dumping.
o Use
only
toilet tissue formulated for use
in
septic
tank
or
RV
sanitation systems.
o Keep
both
knife valves closed and locked, and
the
drain cap
tightly
in place
when
using
the
system on
the
road.
o Use
only
cleaners
that
are approved
for
use in
septic
tank
or
RV
sanitation systems.
o Use a special holding
tank
deodorant
chemical
approved
for
septic
tank
systems in
the
black
water
holding tank. These chemicals aid
the
breakdown of solid wastes, and make
the
system
much
more pleasant
to
use.
o Do
not
put
facial tissue, paper, ethylene
glycol-
based or other automotive anti-freeze, sanitary
napkins,
or
household
toilet
cleaners in
the
holding tanks.
o Do
not
put
anything solid in either
tank
that
could scratch
or
puncture
the
tank.
If
the
drain system does
get
clogged:
o Do
not
use harsh household drain cleaners.
o Do
not
use motorized drain augers.
o Use a hand-operated probe
to
loosen
stubborn
accumulations. Seriously clogged P-traps may
require disassembly.
Be
careful
not
to
overtighten
when
reassembling.
o
Sometimes
the
holding
tank
valve
will
get
clogged.
In
this case, a hand-operated auger may
be
necessary.
Be
ready
to
close the valve quickly
once
the
clog is cleared.
If
the
seal gets
damaged,
it
is easily replaced.
WATER
SYSTEM WINTERIZING
If
the
motor
home is
to
be
stored unheated in
tem-
peratures
below
freezing, the fresh
water
and
waste
systems should
be
winterized.
1.
Drain fresh water tank by opening the water tank
drain valve.
2. Turn
water
pump
on. Open a cold
water
faucet.
When the
flow
of
water stops, turn the
pump
off.
3.
After
opening
hot
and cold
water
faucets, open
the
drain valves on HOT and COLD
water
pipes.
These valves are located under interior cabinets
at
floor
level and drain
through
the
floor.
