Preparation For Winter; Technical Data - Vetus WW25W Instrucciones De Instalación Y Manual De Operación

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 0.3
bar (0.3 kgf/cm 2 , 4 psi).
Vetus supplies a hose suitable for waste water.
Article Code:
Specially for black water tanks:
SAHOSE19, odour-proof waste water hose, 19 mm (5/8")
internal diameter
SAHOSE25, odour-proof waste water hose, 25 mm (1") inter-
nal diameter
SAHOSE38, odour-proof waste water hose, 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.
If required, fit an odour filter '11' between the air-relief pipe and
nipple.
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.

Preparation for winter

The tank, pipes, pump, etc., should always be drained.
Never add anti-freeze to the tank or other parts of the waste
water system to protect against frost damage. Anti-freeze is
very poisonous!
Propylene-based anti-freeze may be used.
Clean the tank according to the cleaning procedure.
Maintenance
Regularly check the air-relief nipple and clean its sieve if neces-
sary.
Regularly check the hoses and hose connections for possible
leaks and fit new hoses and/or hose clips when necessary.
Also check the tank for damage caused by abrasion. Replace a
damaged tank immediately.
At the end of the cruising season, carry out the cleaning and
sterilizing procedures as described under 'Use'.
A tank and installation which is seriously polluted with algae can
be cleaned by thoroughly rinsing out the tank, pump and pipes
with chlorine.
