MACERATOR PUMPS
Your 330 TE comes equipped with two macerator pumps, one port and one starboard. They are con-
trolled by independent rocker switches on the dash panel, and serve to evacuate water and residue from the
in-floor fishboxes. To service the pumps, remove the access plate on the aft vertical wall of either floor
fishbox. The pump and wiring are mounted on a bulkhead aft of the fishbox.
Macerator pumps are self priming, but are susceptible to damage during extended dry runs. For this
reason, the pumps are equipped with a thermal switch. The switch will cycle the pump “OFF” to prevent
damage from excessive heat caused by dry operation. If you have a pump cut “OFF” during operation,
allow the unit at least 15 minutes to cool before attempting to use it again. While you wait, verify the con-
tents of the affected box to be certain you have not emptied them or there are obstructions at the drain pre-
venting the flow of material.
MARINE HEAD
The 330 TE comes equipped with a marine head on the port side of the forward berth. The control
panel for the head, shown below, is located on the vertical wall opposite the toilet. Power is supplied to this
panel through a 20 amp fuse located in the console on the accessory fuse block. The panel controls the
water level in the bowl and the discharge of waste from the head.
Water is supplied to the system from the freshwater tank located in the console Therefore, to operate
the toilet the freshwater system must be pressurized. A solenoid, installed near the head inlet, prevents
water from filling the bowl prior to each use. The macerator pump, located at the rear of the toilet, removes
waste from the bowl and pumps it into the 10 gallon holding tank.
The holding tank is mounted on the port side of the anchor locker compartment and can be accessed
through the anchor locker lid. This tank can be evacuated using the deck pump-out fitting located forward
of the port berth entrance or by overboard discharge using the macerator pump and seacock supplied on
your vessel.
! CAUTION
Foreign objects such as wood or metal should be cleared from the fishboxes prior to macerating
the waste. Failure to do so could result in damage to the plumbing or pump.
NOTICE
In the event the macerator pump will not prime, use the raw water washdown to spray pressur-
ized water into the fishbox drain. Doing so will facilitate priming of the pump.
! WARNING
If the solenoid fails or becomes locked in the open position, shut off the supply system quickly and
evacuate the bowl.
