•
Only human waste and rapid-dissolving boat or RV toilet tissue can be safely flushed into your holding tank.
NEVER flush anything else.
•
Use ONLY rapid-dissolving boat or RV toilet tissue. NEVER use residential-type tissue.
•
Use restrooms onshore when possible. By using onboard facilities only when no other option is available, you will
help prevent overfilling of your holding tank.
•
To check the content level of the holding tank, look at the monitoring gauge (for the location of this gauge, see the
Component Locations section in Chapter 2 of this Owner’s Manual) .
•
Empty the holding tank at every opportunity.
Holding Tank Cleaning Tip
If possible, perform the following steps near the end of each trip to help clean and flush the holding tank:
1. Several miles from the end of each trip, stop at a pump-out station with a non-potable water source.
2. Pump-out the holding tank.
3. Fill the holding tank 1/2 full of fresh non-potable water.
NOTE: Never use a potable (drinkable) water source
to perform this step.
4. Get back underway. The agitation while cruising home will help clean the tank.
5. Empty, flush out, and add a marine holding tank deodorizer to the tank before docking or mooring your yacht.
Winterizing the System
Read the marine head’s operation and maintenance manual for winterizing instructions.
Macerator (If Equipped)
To use the macerator to
pump waste directly over-
board (where laws permit):
1. Open the underwater
discharge valve.
2. Press both macerator
switches at the same
time to run the pump.
3. Stop running the macer-
ator as soon as the hold-
ing tank is empty.
4. Close the underwater
discharge valve when
you are done pumping.

underwater discharge
valve and the macerator
switches, see the
