Installation

General
When choosing a place for the tank and for the deck filler cap,
take the following into account:
- The suction hose should be as short as possible, must go
directly down to the tank and be as straight as possible.
- The space in which the tank is placed should be properly
ventilated.
Position
Position the tank as close as possible to the toilet to avoid dirty
water flowing back into the toilet from the tank when the boat
heels.
Install the tank so that it is easily accessible for inspection.
Also ensure that there is sufficient free space over the top of
the tank for the hose connections. These must be easily acces-
sible during installation. The tank should be 1 cm (
round from bulkheads or other tanks, to provide ventilation.
Ensure that there is a sufficiently solid foundation for placing
and fixing the tank firmly.
The size of a tank increases slightly when it is full.
Take this into account when securing the tank. Attach the tank
using the stainless steel rings supplied.
Fitting in sailing ships
When fitting remember that the filler hose must always be posi-
tioned 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.

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.
The fitting (or fittings) for the supply must be ordered sepa-
rately to fit the particular hose connection size required

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 con-
nector nuts are still tight, tighten
more securely if required. Repeat
this after 4 days.
To prevent blockages caused by hairs and coarse waste in par-
ticular, 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.
