Maintenance
– After cleaning the underside of the seal,
apply light, downward pressure to the top
of the seal while brushing around the full
perimeter of the seal.
I
If the ball pivot arm becomes dislodged
while cleaning inside the base beneath
the flush ball and seal, re-engage it into
the pivot point. Refer to Figure 16 for the
location of the pivot point.

If this procedure does not correct a
leaking seal, it may require replacement.
Detailed replacement instructions are
included with the replacement flush ball
seal kits.
5 .5 Winterizing and Storing the
Toilet

WARNING: POISON HAZARD .
Do not use automotive-type antifreeze
(ethylene glycol) in freshwater systems.
Failure to obey this warning could result
in death or serious injury:

CAUTION: BODILY HARM HAZARD .
This toilet is not intended for use when
exposed to temperatures below freezing.
Failure to obey this caution could result in
minor or moderate injury.
NOTICE: The toilet warranty expressly excludes
coverage for any damages to the toilet or
the vehicle that may occur due to improper
winterization of the toilet. Freeze damage that
results in leaks to the water valve is an indicator
of improper winterization.

Freeze Damage
q
These toilet water valves exceed the applicable
standards for maximum water pressure as
defined by the North American plumbing code
agencies. However, if trapped water freezes in
the piping that supplies water to the toilet, it
expands and creates extremely high pressure
that can damage the valve.
If the freeze damage indicator window (1) has
white stress marks, it indicates freeze-damage.
Water valve damage is due to severe exposure
to below-freezing temperatures.
To avoid damage, winterize the toilet as
described in this manual. If freeze damage
occurs as a result of improper winterization,
replace the water valve with a 300/310/320
series toilet water valve kit.
If the water valve is returned for a warranty claim,
Dometic reserves the right to deny the claim if
the problem is caused by freeze damage.
I
Use nontoxic antifreeze (propylene
glycol) designated for potable water
systems (See the vehicle owner's manual).
When a toilet may be exposed to temperatures
below freezing, the toilet must be winterized
using the "Non-toxic Antifreeze Winterization
Method" on page 12 or the "Drain Water
from the Toilet Method" on page 13. When
a toilet is stored for long periods of time, or the
water becomes stagnant, flush the system using
the "Drain Water from the Toilet Method" on
page 13.
5 .5 .2 Non-toxic Antifreeze
Winterization Method
I
This is the recommended method.
1. Pour non-toxic antifreeze into the potable
water tank according to the instructions from
the antifreeze manufacturer.
2. Flush the toilet (several times) until the
antifreeze has flowed completely through
the toilet.
I
For toilets with a hand sprayer, the hand
sprayer must be turned on for antifreeze
to cycle through the sprayer.
