3488 Motoryacht Owners Manual Supplement
Marine Head System with Holding Tank
Each head (toilet) comes with its own instruction manual that is included in your owners packet. Read the head man-
ual thoroughly before operating your standard manual flush head system or optional electric flush head system or
optional vacuum flush head system and refer to it for winterizing recommendations.
The marine head system installed on your yacht is designed so that waste from each head is flushed into the hold-
ing tank.
The holding tank can be emptied by dockside pump-out or, where permitted, dumped overboard by turning on the
macerator pump from the pilothouse DC panel. The overboard discharge seacock and the holding tank are located
under the stairs leading up to the forward stateroom. The stairs lift out to provide access.
The holding tank features a level indicator, located on the DC panel. Empty the tank at every opportunity. The
indicator is not precise. To prevent possible illegal spillage of waste, avoid filling the holding tank to capacity.
Make sure the seacock is open before using the standard electric head. The seawater intake seacock for the stan-
dard head system is located under the lift out stairs that lead to the forward stateroom.
Your yacht may feature an optional vacuum head system which includes two vacuum generators. The optional
vacuum head system uses water from the fresh water tank to flush the heads and does not have a seawater
intake seacock.
Waste System Routing (Electric Option)
SYSTEM DAMAGE HAZARD! Before operating the standard electric head system, make sure
the systems seawater pickup seacock is open. The seacock must remain open anytime the head
system is in use.
CAUTION!
!
Check local regulations regarding the legal use of marine head systems in your area.
