2016 OWNERS MANUAL / 0279
During water evacuation process, do not operate sea water pump
very long without water. Pump impeller may become damaged.
Winterizing Toilet System
At the end of each season, the macerator toilet should be winterized
for storage by using potable water-safe antifreeze (if boat will be
exposed to freezing temperatures).
If system will be subjected to freezing temperatures, please follow
procedures in this section, “During extended periods of non-use”,
and then winterize system as described here.
NOTE: Use nontoxic antifreeze designated for potable water
systems.
Fresh water system
1. Drain potable water tank and empty holding tank.
2. Add freshwater antifreeze to potable water tank.
3. Flush potable water antifreeze and water mixture through
toilet(s) and into entire system, including the waste holding tank,
diverter valve connections, discharge pumps, etc. Turn off power
to toilet. Each installation is different, so amounts may vary. User
discretion is required to assure adequate protection.
Never use automotive-type antifreeze in freshwater systems.
Special Attention
Use only rapid-dissolve toilet paper with these head systems, and
only deodorant specially formulated for this type of head system.
See the manufacturer’s instructions for details. In the event that
anything from the head’s bowl or holding tank escapes, it should be
cleaned as soon as practicable. Failure to clean any spillage may
result in unpleasant odors, mildew, mold and damage to the deck or
other areas of the boat. This is not covered under warranty.
Trouble Shooting
If the toilet flushes but the water in bowl empties slowly or not at
all, then check the discharge piping for kinks and blockages, and
the macerator pump for blockages. If the macerator pump makes
unusually loud noises, or continually trips the circuit breaker, then
check the pump for foreign material. If the toilet doesn’t flush after
pushing the flush switch, check the tank to see if it is full, check
the circuit breaker has tripped and needs to be reset. If the toilet
doesn’t receive water when the flush button is pushed, check the
water supply line to make sure it isn’t kinked and the water valve
screen to make sure it isn’t blocked. If the toilet still exhibits issues,
then present the boat to and authorized MasterCraft dealer for repair.
