Parallel Connection; Use And Maintenance - Vetus CWS Instrucciones De Instalación

Introduction
The Vetus cooling water strainers model CWS
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 sel­
dom needs to be cleaned.
In a standard installation situation (see 'Instal­
lation examples' , drawing 1 and 2) the capacity
is as per technical data.

Parallel connection

By connection of 2 water strainers in parallel
with the use of 2 extra valves (see 'Installation
example, drawing 3) it is possible to clean each
filter separately while the engine is running.
Installation
• Install the water strainer always above the
waterline.
• Use brackets to mount the strainer against a
vertical bulkhead.
• Install always a sea­cock on the water inlet
scoop!
• Install the water strainer with the inlet di­
rectly to a stand­pipe, see drawing 1, or con­
nect the inlet by means of hose pillar and a
flexible hose, see drawing 2.
• Use a teflon tape as sealant for the connec­

tions.
• To connect the strainer to the engine always
a hose pillar and a flexible hose should be
used.
• Use only water and/or soap to ease fitting
the hoses to the hose pillars and never prod­
ucts 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 accu­
mulated. Close the seacock and open the
lid:
Remove the bolt (A), loosen the other bolt
(B) and open the clamp, see fig. 2.
Remove the strainer element out of the
housing and flush the strainer with clean
water.
• Re­install the strainer element, grease the
O­ring and the thread with e.g. silicone oil
or teflon based spray, see drwg 6, and rein­
stall the lid.
