Dufour 412 - Seacock Operation and Maintenance

18/82
Seacocks
Seacocks are of the ¼-turn type:
- OPEN position: handle in line with seacock body,
- CLOSED position: handle perpendicular to the seacock body.
ATTENTION!
● Never interfere with the tightening of the seacocks to the hull. In the event of a leak,
consult a professional.
● In bad weather or when leaving your boat, close all the sanitation system seacocks.
● Keep seacocks closed when not in use.
● During wintering, clean and rinse the seacocks and skin-fittings. Inspect brass fittings;
slight surface corrosion is normal.
● In the event of more serious corrosion, consult your agent.
Operation of the sea toilets
- Open the sea water inlet cock.
- Open the bowl emptying seacock.
- Set the lever to the “FLUSH” position.
- Operate the pump.
- To empty the bowl and avoid any water slopping when heeling, set the lever to the “DRY
BOWL” position.
- Operate the pump until the bowl is dry.
- Repeat these flushing / emptying operations as many times as is necessary to ensure
complete emptying of the pipes.
When toilets are not being used, set the lever to the "DRY BOWL" position, or the «CLEF»
position for certain models.
- Close seacocks after use, as the toilet is below the waterline.
- Change the toilet seals regularly.
Holding tank operation (ISO 8099:2000)
ATTENTION!
Where a holding tank is fitted, take care to lock the discharge valve, to avoid any accidental
discharge during wintering.
- The sewage tank operates using the manual toilet pump.
- The contents of the toilet pan are discharged straight into the holding tank.
- Periodically check that the vent is working properly.
- A deck plate is provided for emptying the tank.
- The discharge valve can be sealed in the closed position using a padlock.
- Once a season, arrange to clean out the tank using a biodegradable disinfectant chemical.
Leave the system empty if the vessel is to be left in below-freezing temperatures
