Backwashing
The filter must be backwashed (= cleaned)
at the specified cycles in order to remove the
filtered dirt from the fine filter screen (
12
).
The backwash reminder alarm is accommo-
dated in the lid of the handwheel (
2
) of the
JPF
+
¾" - 1¼". It uses a beep to remind
every two months that the filter must be
backwashed. Press the
RESET
-key (
1
) (keep
pressed for at least 3 seconds) in the lid of
the handwheel (
2
) to switch off the beep and
to restart the two-month time interval.
The backwash process uses a patented
point-rotation system
with simultaneous
cleaning of the inside of the filter hood:
Turn the handwheel (
3
) counterclockwise to
rotate the suction nozzles in a helical move-
ment around the fine filter screen (
12
). They
progress upwards with each revolution until
the entire sieve cloth has been sucked up
one time. That is reached when the
handwheel (
3
) has been turned to its limit. At
the same time, the flushing valve (
11
) on the
bottom of the filter opens and the backwash
water can exit. During this, pure water flows
from the interior to the outside through the
sieve surface in the suction nozzle, pulling
along the adhering particles.
After reaching the upper limit stop, turn the
handwheel (
3
) clockwise to re-close the
flushing valve (
11
). The sieve cloth in the
fine filter (
12
) is then sucked through the
suction nozzle a second time. During this
step, the suction nozzle does not only clean
the sieve cloth in the fine filter (
12
) but also
the transparent filter hood (
6
) using a rubber
lip on its exterior side.

All filter sizes are backwashed with
treated water. The treated water
supply within the domestic installa-
tion is maintained throughout the
backwashing performance. During
the backwashing any wastewater
can't get into the pure water side.
