Operation
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Always observe the chapter “Intended use”!
5.1
Commissioning
Before starting up (initial putting into service
or startup after maintenance work),
fill
the
magnetite filter with water! Observe the
following:
–
Close or keep closed the shut-off valve
downstream of the unit to ensure that air
cannot be introduced into the system.
–
Open the shut-off valve upstream of the
unit.
–
The magnetite filter is now under operat-
ing pressure.
–
Air trapped within the unit is now auto-
matically removed via the integrated
aeration unit. We recommend a rinse
after aeration (see chapter “Rinsing”).
–
The filter comes delivered with the cover
cap (
1
) on the aeration unit (
2
) being
open one turn to ensure air can be evac-
uated freely (see fig. 5).
–
The magnetite filter is ready for opera-
tion once the rinsing and aeration cycle
has been completed and the shut-off
valve downstream of the unit has been
opened.
5.2
Functional description
Centrifugal separator
Heating water flows through the built-in
rotary flange into the magnetite filter where
particles in the incoming water are set in
rotation by the splitter (
3
) and, as in a centrif-
ugal unit, carried to the unit's outer wall
where they sink to the unit floor. Here they
are collected and flushed out through the
ball valve (
4
) (see chapters “Rinsing” and
“Rinse interval”). Gases present in the water
gather in the upper chamber of the unit and
are released out through the integrated
aeration system.
