2.3 Connecting the tank
Use good quality reinforced hose to connect the tank. Avoid sharp
kinks in the hose.
The reinforced hose must be of foodstuffs quality and at least resist-
ant to a temperature of 60˚C and a pressure of 400 kPa (4 bar).
Vetus supplies a hose that is suitable for tap water. This hose has no
taste, is non-poisonous and resistant to temperatures from -5˚C to
+65˚C.
Art. code:
DWHOSE12A, drinking water hose int. ø 12 mm,
DWHOSE16A, drinking water hose int. ø 16 mm and
DWHOSE38A, drinking water hose int. ø 38 mm.
Use a good hose clamp for each hose connection.
Fit a filler hose A,
internal diameter 38 mm, between the filler cap
and the tank. Fit this hose so that neither the tank nor the filler cap is
mechanically stressed.
Fit the breather nipple 1
as high as possible,
above the level of the
top of the tank.
Choose a suitable place for the breather nipple so
that rain or water from outside cannot penetrate.
Fit the breather pipe B,
internal diameter 16 mm, between the
breather nipple and the tank connection 3. The breather pipe must
be fitted so that it is continuously sloping upwards as seen from the
tank.
Fit the tap water pipe
, internal diameter 16 mm, between connec-
tion point 4 and your pump. The pump must be self-priming. This
may be fitted at any height relative to the tank.
2.4 Check
Check the system for any leaks.
Test pressure 20 kPa (0.2 bar, 4.4 psi).
