8 .2 .3 Extended Periods of Non-Use
NOTICE:
The macerator toilet and sanitation system
should be protected if the toilet will not be used for
more than two weeks, especially in hot weather.
NOTICE:
Do
not
use detergent that contains bleach or
environmentally harmful substances.
Complete these steps to protect the toilet before
storage or before two or more weeks of non-use.
1. Flush the toilet in normal mode and add 4 oz (118 ml)
of liquid biodegradable laundry detergent.
2. Flush the toilet at least five times.
3. Turn off the water supply to the toilet.
4. Flush the toilet three times without water.

This procedure will minimize any remaining water in
the macerator pump.

temperatures, continue with “Winterizing” on
page 12.
8 .3 Winterizing
NOTICE:
This toilet is
not
intended for use when
exposed to temperatures below freezing.
NOTICE:
Never
leave the vehicle unoccupied for
extended periods of time with the municipal water
supply or the onboard water pump turned on when
there is a possibility of freezing temperatures.
NOTICE:
Never
use automotive-type antifreeze
(ethylene glycol) in freshwater systems. Use only
nontoxic antifreeze (propylene glycol) designated for
potable water systems. See the vehicle owner’s manual.
At the end of each camping season, or when the vehicle
is stored for long periods of time when the toilet may be
exposed to freezing temperatures, the system should be
winterized by using potable water-safe antifreeze.
Complete these steps to winterize the toilet:
1. Drain the potable water tank and empty the waste
holding tank.
2. Add freshwater antifreeze to the potable water tank
according to the antifreeze manufacturer instructions.
3. Flush the toilet several times until the antifreeze
mixture has flowed completely through the toilet, the
macerator pump, and the holding tank.
4. Turn off the power to the toilet.
I
Each installation is different, so the antifreeze
mixture amounts may vary. User discretion is
required to assure adequate protection.
