4.7 SEPTIC SYSTEM/BLACK WATER SYSTEM
The system consists of the toilet bowl and a septic tank. It operates:
1. by discharging the black water through a hull bottom valve
2. or with the suction hose emptying the tank by a stationary vacuum machine, through
the deck vacuum discharge outlet, located on starboard side deck.
INSTRUCTION MANUAL
✓ Read the user manual for the toilet system.
Picture 24: Toilet controls (1), ventilation (2), water level trimmer shaft (3)
When the toilet isn't used, the water level should be 1 cm above the outlet hole in the ceramic
bowl. If for any reason, more or less water is wanted in the ceramic bowl, it can be adjusted by
turning shaft trimmer in the rear part of the control panel, accessible through cupboard below
the sink.
Do not go to sleep, while the septic tank is full. The morning sunlight can heat up
full septic tank and stinking gas will appear as a result of expansion.
