Winterization
This toilet must be winterized to avoid
freeze damage. Failure to do so will void
warranty.

Refer to your vehicle manufacturer’s
winterization procedure for further informa-
tion.
Trouble Shooting
1)
Leaks
:
a) Back of toilet: check water supply line connec-
tion.
b)
Between closet
fl
ange and toilet:
check
Screws for tightness. If leak continues, remove
toilet and check
fl
ange height. Adjust, if neces-
sary, to 7/16” above
fl
oor. Replace
fl
ange seal
if damaged.
2)
Bowl will not hold water:
Check for and
remove foreign material in valve blade groove
in the
fl
ush drain. If necessary, replace blade
seal.
3)
Poor
fl
ush:
A good
fl
ush should be obtained
within 2 to 3 seconds. If problem persists,
remove the water supply line and check
fl
ow
rate. The
fl
ow rate should be at least eight
quarts (7.6 liters) per minute.
4) Flush or Add Water stops after 10 seconds
(Aria Deluxe II only):
an automatic shutoff is
normal.
5) No electric operation (Aria Deluxe II only):
check for blown/broken fuse. If needed, replace
with a 4-amp Slow-Blow Fuse (Littlefuse 4-amp
3AG Slow-Blow or Thetford Part #19630). Fail-
ure to use the proper fuses and/or connections
may result in damage to the Toilet or the RV
and void the Warranty.
CAUTION: To avoid breaking glass fuse,
pull fuse holder STRAIGHT apart. Do not
bypass the in-line fuse supplied with
the toilet.
Manual override
In the event of a power outage, the
contents of the bowl can be released
to the holding tank by opening the
valve manually using the overrride
knob on the back of the toilet. Turn
clockwise to open, counter-clockwise
to close.
