Connector Nipples
Both connector nipples must be fitted in the top of the tank, the 16
mm. outlet nipple should be fitted as low as possible. One connector
nipple (16 mm. ) is already fitted in the tank. Choose a suitable posi-
tion for the other (38 mm.) connector nipple. The holes required for
both connector nipples (16 and 38 mm. diameter) are the same. If
necessary, the nipples can be changed over.
Fit the nipples as follows:
1. Draw the hole with a ball-point pen, use the ring as stencil. The
diameter is 42 mm , do not make the hole too large!
2. Use scissors to cut the hole in the tank. Do not cut into the oppo-
site tank wall!
3. Fit the connector nipple into the tank.
4. Fit the ring and nut. Tighten the nut with the wrench, never use
water pump pliers. Do not tighten too hard.
• After filling the tank, check at once to see that the connector nip-
ples do not leak. Tighten the nuts if required. Repeat this after 2
days, and again after 4 days.
• Clean the inside of the tank.

Tank Connections
Connect the tank up with good quality reinforced hose. Avoid sharp
kinks in the hose and ensure there is sufficient play to follow the
movement of the tank, from empty to full.
The reinforced hose must be of quality suitable for drinking water
and resistant to a temperature of at least 60 degrees C (140 degrees
F)and a pressure of 400 kPa (4 bar, 28 psi).
Vetus supplies a hose suitable for tap water. It is tasteless, non-poi-
sonous, resistant to temperatures from -5 to +65 degrees C (+23 to
149°F) and has a working pressure of 1500 kPa (15 bar) - 16 mm dia.
(218 psi -

DWHOSE16A, drinking water hose, 16 mm. internal diameter, and
DWHOSE38A, drinking water hose, 38 mm. internal diameter.
Fit each hose connection with a good hose clamp.
Fit filler cap A
Install a filler hose B, 38 mm. internal diameter, between the filler
cap and the tank. Instal this hose in such a way that the filler cap is
not subject to mechanical loads and the hose can follow the move-
ment of the tank.
Fit the tap water supply pipe C, 16 mm.internal diameter, between
tank and pump. A non-priming pump should be lower than, or at the
same height as the underside of the tank. A self-priming pump can
be mounted at any height in relation to the tank.
