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.
Each installation is different, so the antifreeze
I
mixture amounts may vary. User discretion is
required to assure adequate protection.
