Use And Maintenance - Vetus FTR470 Serie Instrucciones De Instalación

Introduction
The most important characteristics of the Vetus
cool water filter type 470 are:
• Easy to inspect: the transparent lid makes
inspecting the filter possible without open-
ing the unit.
• Easy to open: simply unscrew the central
button, (no tools required), to open the unit
and clean the filter.
• Low maintenance: thanks to the large active
surface area, the filter element requires infre-
quent cleaning.
• Easy to install: thanks to the separate assem-
bly bracket and the clamping strip, the filter
is easy to install. It can also be rotated 360°,
allowing the hose connections to be prop-
erly positioned.
In a standard installation situation (see 'Installa-
tion examples' , drawing 1) the capacity is as per
table at page 15, the capacity depends of the
diameter of the hose connection.
Parallel connection
By connection of 2 water strainers in parallel
(see 'Installation examples, drawing 2) a larger
capacity can be obtained.
By connection of 2 water strainers in parallel
with the use of 2 extra valves (see 'Installation
4
030506.01
examples, drwg 3) it is possible, while the en-
gine is running, to clean each filter separately.
Installation
• Install the water strainer always above the
waterline. Mount the strainer against a verti-
cal bulkhead.
• Install always a sea-cock on the water inlet
scoop!
• Use for both connections, water scoop to
strainer and strainer to engine, always flex-
ible hose.
• 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.
Pay attention to the flow direction through
the filter!

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.
