JUDO PROMI
15
Operation
Experience shows that increased dirt is
deposited during the initial running period. If
so, the unit has to be flushed more often
than usual.
Failure to backwash regulary can cause
damage to the sieve. Larger quantities of
filtered particles can deform the sieve and
as an extreme incident can cause tearing of
the sieve. As a result the filter function is no
longer ensured. In addition, larger quantities
of dirt can cause mechanical impairment
concerning the backwashing function.
5.4.2 Note electronics
(only for JPM ¾" – 1¼")
The note electronics in the handwheel
reminds you to backwash every 2 months.
You can also mark the next backwash date
using the adjusting ring under the hand-
wheel.
–
Push the
RESET
-key to stop the beeping.
This also restarts the 2-month time
interval. Be sure to check batteries regu-
larly to ensure they have not been
exhausted. The beep is only considered
an additional reminder for backwashing.
Independent of that, the backwashing
needs to be carried out every two
months at the latest.

Modifications / changes /
spare parts
ATTENTION
(see chapter “Safety information and
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 filter, lead to leaks
and as an extreme incident they can lead to
the bursting of the filter.
The imprinted test marks are only valid if
original spare parts are used.
5.5.1 Servicing / Repair
Prior to servicing or repairing the PROMI.
You must turn off the water supply valve,
located upstream of the unit and depres-
surize the filter.
Failure to observe this can lead to property
damage and personal injury.
Strict compliance with the instructions given
in the “Installation” and “Maintenance” chap-
ters is required.
