14.2.3 Expansion tank
An expansion tank (a) is installed next to the pump. Its
function is to optimise the operation of the pump and to
ensure a smooth flow of the water.
The expansion tank is adjusted to a pressure of 0.9 bar
that is suitable for operation with the pump installed as
standard on the vehicle. The pressure can be adjusted
with a standard compressor by means of the appro-
priate valve (b). It is recommended to check the
pressure at least once a year, using a pressure gauge.
In the case of replacement of the pump with a different
type, it is necessary to change the pressure of the
expansion tank.
Refer to the manufacturer handbook for further infor-
mation on the expansion tank.
