1 Introduction
This manual applies to the Vetus (permanent) plastic drinking water
tanks with built-in electric pump.
See the drawings on Page 30 for dimensions. Tolerances of + or - 2%
apply to all dimensions!
2 Installation
2 1 General
Take the following into account when choosing a position for the
tank and the deck filler cap: the filler hose must be as short as pos-
sible, must slope down continuously from the deck cap to the tank
and must be as straight as possible.
Positioning
• Position the tank in such a way that it is readily accessible for in-
spection.
• Also make sure that there is sufficient free space above the tank
for the hose connections.
• These must be easily accessible during fitting. There must be free
space with no bulkheads or other tanks of about 1 cm all round
the tank to allow ventilation.
• 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 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.
2 2 Inspection cover and fittings
The inspection cover and the fittings are pre-assembled in the upper
section of the tank.
• Undo the bolts so that the fittings can be placed the right way
round.
• 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.
• The sensor for a water level meter is already fitted in the top of the
tank. The sensor can be connected only to a Vetus level indicator
for water.
Drinking water tank systems DWSC
In a pressurized water system the pump will be switched on immedi-
ately after the pressure has dropped when water is tapped ensuring
a continuous flow of tap water.
The height difference between the tank and the filler cap may
be a maximum of 2 metres (the maximum excess pressure in the
tank is 20 kPa (0.2 bar)!)
