Macerator Delete Head System (Option)

The optional macerator delete head system uses raw water to flush
waste from the toilet directly into the holding tank. The holding tank
is plumbed to a fitting on the deck for dockside pump-out only.

Vacuflush Head System (Option)

• The optional vacuflush head system uses freshwater (not raw
water) to flush waste from the toilet, through a vacuum generator,
and into the holding tank.
• If the system is equipped with a macerator pump, waste may be
pumped from the holding tank into the water through an underwa-
ter discharge seacock (where regulations permit). The macerator
switches are located at the helm station and must both be pressed
simultaneously for pumping to occur.
• If your yacht does not include a macerator (macerator delete
option), waste can only be pumped out of the tank to the recepta-
cle on the deck for dockside pump-out only.
