Cooling water strainer model 150
Introduction
The Vetus cooling water strainers model 150 are equipped with
a transparant lid, inspection therefore, can be carried out without
opening of the strainer.
Due to the large active surface the strainer seldom needs to be
cleaned.
In a standard installation situation (see 'Installation example', drwg
1) the capacity is as per technical data, the capacity depends of the
diameter of the hose connection.
Installation
Install the water strainer always above the waterline. Mount the
strainer against a vertical bulkhead.
Install always a sea-cock on the water inlet scoop!
Use for both connections, water scoop to strainer and strainer to
engine, always flexible hose.
Use only water and/or soap to ease fitting the hoses to the hose
pillars and never products containing grease or oil.
Fit each hose connection with 2 stainless steel hose clamps.

Use and maintenance

Inspect the strainer element regularly for contaminents.
N.B. The lid doesn't need to be removed for inspection.
Clean the strainer element if dirt has accumulated. Close the sea-
cock. Unscrew the wing nut and remove the lid of the water strain-
er, see drwg 2. Remove the strainer element out of the housing and
flush the strainer with clean water. Re-install the strainer element,
grease the O-ring with e.g. silicone oil or teflon based spray, see
drwg 4, and reinstall the lid.
N.B. Secure or loosen the wingnut always manually. Never use
tools for this purpose, see drwg 2 and 3.
Check the seal between lid and housing after cleaning and re-
assembling the strainer. An improperly sealed lid will result in air
sucked in by the sea water pump of the engine which again will
result in overheating of the engine.
To prevent damage of the water strainer, during frost in the winter
time, either the water must be drained or the installation must be
filled with anti-freeze.
Remove the hoses to drain the strainer; the housing is not equipped
with a drain plug.
Take care that during filling with anti-freeze no anti-freeze is spilled
into the waterway. Anti-freeze is poisonous.
