9.3 Installation
•
Vent the coalescer housing before starting up the unit.
To do this, loosen the vent screw on the housing cover,
then close it again as soon as liquid starts to exit.
10 Start-up
DANGER!
This coalescer is not allowed to be put into operation until
the relevant machinery into which it is to be incorporated
has been declared in conformity with the applicable EC
directives, harmonised standards, European standards or
equivalent national standards.
•
Only approved hydraulic fluids may be
filtered (refer to section 5).
•
The coalescer must not be started up if it
exhibits visible damage.
Make sure the protection caps have been removed from
the connections.
Make sure there are no open connections into the
atmosphere.
Start up the unit.

Danger if the unit is operated incorrectly!
Risk of damage to property.
•
Prefiltration is recommended.
Please always ensure that you have a
sufficient quantity of original FG replacement

cannot be cleaned.
The coalescer is used to separate water from hydraulic
fluids / diesel / marine diesel oil.
The separated water collects in a special reservoir and
must be drained off as soon as the water level sensor
trips.
If the coalescer element is dirty, the red button of the
maintenance indicator on the cover of the coalescer
housing jumps out and an electrical signal appears.
The optimum working range is a ∆p of 0.4 ± 0.2 bar.
Water drain
•
The water must be disposed of in a manner
which does not pollute the environment.
