Rinsing
In order to remove sludge and particles from
the system, the magnetite filter must be
rinsed at regular intervals.
Refer to chapter "Dangers during rinsing"
before commencing!
In order to obtain an optimal unit rinse, first
close the shut-off valve downstream of the
filter. To rinse open the ball valve at the bot-
tom of the unit. Observe the following:
The filter comes delivered with the ball valve
closed and capped. Before opening the ball
valve, remove the cap (1), then insert the
spout (2) and fix it in place with the union nut
(3). The ball valve may now be opened by
means of the cap (see fig. 8).

Safety ball valve
Danger of scalding!
During rinsing heating water flows through
the filter, washing sludge and particles col-
lected on the unit floor out through the ball
valve. After 2 - 3 ltrs. of water have run
through, the ball valve must be firmly closed.
Re-open the shut-off valve downstream of
the unit once rinsing is complete.
Check the systems pressure after rinsing as
a top up may be required.
A top up will then bring the unit back to the
correct operating pressure and, where no
automatic fill system is available, be carried
out manually. Pressure levels in the system
and in the expansion vessel should be set
before commissioning the magnetite filter
and checked and adjusted at least once per
year.

Rinse interval
Where retrofitted into an existing system,
the magnetite filter should be rinsed at least
every 14 days until the water removed
becomes visibly clearer. After that, as with
new installations, once at heating start up
and once when the system is shut down is
enough.

Modifications / changes /

ATTENTION
(see
chapter
"Safety
dangers due to non-compliance")
Only original spare parts are to be used!
Arbitrary modifications and changes are
prohibited for safety reasons! They can
impair the function of the magnetite filter and
lead to leaks.
