The head macerator pump, "Y" valve, holding tank and brass seacock are all installed below the sink area in the

head.

The head macerator pump is used in the overboard discharge operation. The "Y" valve must be in the correct

position to direct the waste either overboard or to your marina's dockside discharge facilities. Before utilizing the

dockside or overboard discharge functions, make certain that the "Y" valve is in the correct position.

Before attempting to flush the toilet, make sure that

the seacock is in the open position. The seacock is

open when the yellow lever is in the full upright

position.

When the lever is in the horizontal

position, the seacock is closed.

The "Y" valve is installed on the port side of the

pump, just outside the view of the photo to the

right.

It allows you to switch back and forth

between dockside and overboard discharge. The

photos below show the 2 positions for the "Y" valve

(i.e., dockside discharge vs. overboard discharge).

Dockside Discharge - When at a marina that offers dockside discharge, the marina will provide the external

facilities needed to perform the dockside discharge operation. To operate the dockside discharge, turn the "Y"

valve to the dockside discharge position as shown here.

The "Y" valve for the Electric Head as shown here is set to use dockside discharge. Follow the arrows. Waste is

going from the holding tank, to the "Y" valve and then upward to the waste outlet.

The waste outlet is a stainless steel fitting, labeled waste. It is located

amidships on the starboard gunwale. Twist the waste outlet cap to open the

fitting and insert the hose provided by the marina into the waste outlet to

connect to your marina's dockside service facilities. Follow the instructions

provided by the marina to operate their equipment.

Warning: Waste in the holding tank can form methane, an

explosive gas.

maintenance is done to the sanitary system.

Overboard Discharge - To operate the overboard discharge, turn the "Y"

valve to the overboard discharge position. The "Y" valve for the Electric Head

as shown here is set to use overboard discharge. Follow the arrows. Waste

is going from the holding tank, to the "Y" valve and then to the electric head

pump. Then, go into the head area and flip the macerator switch to the on

position.

Before using the overboard discharge system, be sure to check with your

local authorities, U.S. Coast Guard, local marina or your dealer for the rules
