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 connector nuts are still tight, tighten
more securely if required. Repeat this after 4 days.
To prevent blockages caused by hairs and coarse waste in particu-
lar, 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.
2 3 Tank connections
Connect the tank with a good quality reinforced hose. Avoid sharp
bends and kinks or sagging in the hose.
Bracket the hose at not too far apart, regular points, to prevent the
hose sagging. Deposits will collect in these sags, causing a blockage
after time.
The reinforced hose should be an odour-proof waste water hose
and resistant to a limited under- and over-pressure of 30 kPa (0,3
bar, 4 psi).
Vetus supplies a hose suitable for waste water.
Specially for black water tanks, odour-proof waste water hose:
Article Code: SAHOSE19, 19 mm (3/4") internal diameter
SAHOSE25, 25 mm (1") internal diameter
SAHOSE38, 38 mm (1 1/2") internal diameter
Fit every hose connection with a good stainless steel hose clip.
Install hull outlet with valve '8'
Fit the air-relief nipple '10' as high up as possible above the level of
the top of the tank. Choose a place for the nipple where rain or other
outside water cannot enter.
Fit the air-relief pipe '14' , internal diameter 19 mm (5∕8"), between
the air-relief nipple and the tank. When viewed from the tank, the
air-relief pipe should run straight upwards.
It is very advisable to fit a smell filter '15' type NSF in the pipe. This
prevents unpleasant smells from the vent nipple.
2 4 Check
Check the system for any leaks.
Extraction pressure 20 kPa (0.2 bar, 3 psi).
