Prestige 500 - Black Water System

The boat is fi tted with electric toilets and a 120 litres holding tank under the
fl oorboard, in front of the bed.
The WC working is based on a depression draining system and the use of the
domestic fresh water for rinsing (approximately 0,6 litre per rinse).
The crew cabin (optional fi tting) is fi tted with manual toilets and with a 50
litres black water tank located in the port side technical room.
 USE OF THE MANUAL TOILETS (CREW CABIN)
- Open the water inlet and drain valves (under the wet room cabinet).
To empty the bowl:
- Set the control lever of the pump slantwise (FLUSH) and operate the pump.
To dry the bowl:
- Set the lever back vertical (DRY) and operate the pump.
In order to avoid clogging the toilets, use absorbent paper only and pump until
the emptying hose is completly empty.
Regularly rinse the toilets with fresh water.
Close the valves after each use.
 USE OF THE ELECTRIC TOILETS
Check fi rst that the WATERPUMP and water group switches located on the
instrument panel are activated.
The FULL switch allows to fi ll up the bowl before use.
The QUICK FLUSH switch allows to rinse and fi ll up the bowl after light use.
The FLUSH switch allows to rinse and fi ll up the bowl twice after intense use.
The EMPTY switch allows to drain off the bowl only.
 USE OF THE HOLDING TANKS
Watch the black water level using the gauge located next to the electrical
toilet, in the front wet room.
The black water tank in the front wet room is emptied by an electric pump.
The crew cabin black water tank is emptied by gravitational force.
Make sure the drain valve of the tank is closed in order to avoid any inadver-
tent discharge (the valve is closed when the handle is perpendicular to the
hose).
Tank drainage:
- In an authorized area, after switching on the domestic 24 V circuit and ope-
ning the drain valve located in the front wet room, drain the tank using the
switch located in the front wet room.
Concerning the tank located in the technical room, open the outlet valve.
