Dufour 430 - Seacocks

ENGLISH 26/02/2019 18/92 DUFOUR 430 Grand Large
Seacocks
Seacocks are of the ¼-turn type:
- OPEN position: handle in the direction of the seacock body,
- CLOSED position: handle perpendicular to the seacock body.
CAUTION!
●
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 the seacocks closed when not in use and remember to manipulate them regularly to
maintain their flexibility of use. An unused seacock can eventually seize up.
●
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)
CAUTION!
Where a holding tank is fitted, take care to lock the discharge valve, to avoid any accidental
discharge during wintering.
- Black water tanks operate with 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. Use a
biodegradable deodorant product without formaldehyde to limit odours.
Leave the system empty if the vessel is to be left in below-freezing temperatures. During winter lay-
up, use a food-grade, non-toxic antifreeze that complies with local regulations.
