• Ensure that there is a sufficiently solid foundation for placing and
fixing the tank firmly.
• The size of the tank increases slightly when it is full Take this
into account when fixing the tank in place.
• Attach the tank using the stainless steel rings supplied.
Fitting in sailing ships
When fitting remember that the suction waste water hose must al-
ways be positioned on the same side of the ship as the tank.
This prevents too high a pressure from possibly occurring in the tank
when sailing at an angle.
2 2 Tank fittings
The following parts are already pre-assembled on the top of the tank.
- Fitting 38 mm (1 1/2") with suction pipe (extraction) (1)
- Fitting 19 mm (3/4") breather (ventilation) (2)
- Inspection lid (3)
One ø 43 mm (1 11/16") hole (4) for the supply has been drilled in
the top. If more supply connections are required drill extra holes
(ø 43 mm, 1 11/16" dia.) for the extra fittings.
• Select the place for the fittings so that if the ship is sailing heeled
over contaminated water from the waste water tank cannot flow
back to the toilet or flow out of the tank through the tank vent
pipe.
• If necessary loosen the nut with the spanner supplied in order to
turn the fittings to the required direction. Remember to tighten
up the nut properly afterwards.
• Remove any dust from drilling or cutting from the tank.
Assemble fittings
• Assemble the fittings with the gasket rings supplied. Tighten the
nuts using the wrench, never with water pump pliers. Do not
tighten the nuts excessively.
• After 2 days check that the connector nuts are still tight, tighten
more securely if required. Repeat this after 4 days.
To prevent blockages caused by hairs and coarse waste in particu-
lar, all fittings should have burrs removed internally, local narrowing
should be reduced to a minimum and any changes in pipe diameter
should be done using conical adapters or large radii.
