Aria DELUXE II Operation
AriaCLASSIC To add Water To flush
Overfill Auto Shutoff
If the Add Water function is run long enough
to overfill the bowl, it will automatically shut
off. This will also occur if the toilet senses
a malfunction.
Once this happens, the toilet electronics
must be reset by cutting off and then re-
storing power to it, preferably at the RV’s
electrical panel. Alternatively, you can pull
apart and reconnect the yellow in-line Fuse
Holder at back of toilet (see Troubleshoot-
ing, Part 5). If problem recurs, your toilet
may need service (see page 5).
Flush Modes
There are two flush modes avail-
able, controlled by the Mode Selec-
tor Switch located at back of toilet.
A is Residential Mode; Bis User
Control/Water Saver Mode.

Winterization
This toilet must be winterized to avoid
freeze damage. Failure to do so will void
warranty.
1) Drain RV’s potable water supply.
2) Flush all of toilet’s plumbing with RV-type anti-
freeze (Propylene Glycol).
Refer to your vehicle manufacturer’s
winterization procedure for further informa-
tion.
Trouble Shooting
1) Leaks:
a) Backoftoilet:checkwatersupplylineconnec-
tion.
b) Between closet flange and toilet: check
Screwsfortightness.Ifleakcontinues,remove
toiletandcheckflangeheight.Adjust,ifneces-
sary, to 7/16” above floor. Replace flange seal
if damaged.
2) Bowl will not hold water: Check for and
remove foreign material in valve blade groove
in the flush drain. If necessary, replace blade
seal.
3) Poor flush: A good flush should be obtained
within 2 to 3 seconds. If problem persists,
remove the water supply line and check flow
rate. The flow 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):

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
