Installation; Use And Maintenance - Vetus 330 Installationsanleitung

Introduction
The Vetus cooling water strainers model
330 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 examples', drwg 1) the capacity
is as per technical data, the capacity
depends of the diameter of the hose con-
nection.
Parallel connection
By connection of 2 water strainers in paral-
lel (see 'Installation examples, drwg 2) a
larger capacity can be obtained, see
'Technical data'.
By connection of 2 water strainers in paral-
lel with the use of 2 extra valves (see
'Installation examples, drwg 3) it is possible,
while the engine is running, to clean each
filter separately.

Install the water strainer always above the
