Toilet operation when connected to “full tank” shut-down relay
and tank monitor system
When a Dometic macerator toilet system uses a “full tank” shut-down relay, electrical power to the
toilet is shut off when the holding tank level reaches “full”. To restore electrical power to the toilet
for flushing, holding tank contents must be emptied or discharged until the “full” tank indicator is not
activated.
Caution – Do Not Flush Foreign Objects!
Flush only water, bodily wastes and rapid-dissolving toilet
tissue. Do not flush wet wipes, sanitary napkins, condoms,
diapers, paper cups, cotton swabs, food, hair or liquids
such as oils or solvents as clogging or damage to the toilet
or toilet system may occur.
Note
Make sure all guests understand toilet operation before use.
Caution – Do Not Flush Waste with “Dry Bowl” Switch!
To maintain proper cleanliness and operation of the toilet and macerator pump, water
should be used with every flush.
6.4.1 Toilet system start-up (toilet with DFS-1F switch)
1. Open sea water inlet and toilet discharge outlet seacocks.
2. Press “Flush” switch (1) and hold for at least 10 seconds.
3. Toss several sheets of toilet paper into bowl and repeat cycle.
The bowl should completely clear.
6.4.2 Normal toilet operation
FLUSHING TOILET
Press “Flush” switch (1) down and hold until waste drains from toilet bowl (about 10 – 20 seconds).
This switch activates a macerator pump that siphons water and waste from the bowl, macerates,
and propels the effluent to the discharge line.
To use less water for liquid-only flushes, press “Flush” switch for shorter period of time.
If toilet bowl does not completely flush and fills up with sea water during flush, partially close inlet
valve until bowl clears and completely discharges effluent. Then, with inlet and discharge valves
completely open, flush toilet for a few seconds to clear toilet and discharge system.
6.4 Sea Water Flush
Caution! Hazard of Flooding
If toilet is connected to ANY through-the-hull fittings, ALWAYS close seacocks when
toilet is not in use (even if boat is unattended for a brief period). All passengers MUST be
instructed on how to close valves when the toilet is not in use. Failure to do so can result in
flooding which can cause loss of property and life.
