9.9 BLACK WATER (SEWAGE) SYSTEM
9.9.1 Operating the WCs
The WCs of the heads are ceramic marine-type and are flushed with
fresh water. The waste from the WCs is directed to the black water
(sewage) holding tank. The WCs have two buttons: BEFORE USE &
AFTER USE.
1. Button BEFORE USE
2. Button AFTER USE
Pushing the BEFORE USE button automatically introduces a pre-
determined quantity of seawater into the bowl, preventing waste remains
from clinging to the ceramic walls.
Pushing the AFTER USE button floods the bowl with fresh water, which
breaks up the waste and sends it to the black water (sewage) holding
tank.
On the toilets control panel a LED indicates:
3. Green, system activate - red, holding tank full toilet disabled
To change the quantity of water introduced into the WC by the AFTER
USE button, and therefore the opening time of the solenoid valve, remove
the toilet control panel (4) and change the setting of the adjustment
regulator.
Regularly pour an appropriate marine disinfectant/treatment liquid into
the WCs, following directions on the product label.
Before entering the harbor, check the black water (sewage) tank and
drain it if necessary (beyond land borders) to avoid having to return to the
open sea to empty the tank.
NOTICES
Do not put anything other than human waste and single-ply toilet paper
into the WC.
i
ENVIRONMENT NOTICE
Do not discharge black water (sewage) inside harbors or marinas or
near beaches. Observe the applicable environmental laws and
regulations for overboard discharge.
