Operation
•
at least every 2 months
•
if the water pressure drops
•
if the filter is visibly dirty
Experience has shown that new installa-
tions in the early stages of installation lead
to increased dirt deposits. In this case, a
more frequent backwashing is necessary.
4.1.2 Backwashing
WARNING
Persons who, due to their physical,
sensory or mental abilities or their
inexperience or lack of knowledge,
are unable to operate the device
safely may not operate it without
supervision or instruction from a
responsible person.
Before carrying out a backwash,
ensure that the wastewater con-
nection is functional.
At the end of the backwashing
process, turn the handwheel until
it engages so that no more back-
wash water escapes. Otherwise,
water may constantly escape and
cause water damage.
1.
Turn the handwheel in any direction
by a full turn.
Backwashing water
escapes.
2.
Turn the handwheel until it clicks into
place. Ensure that no water escapes.
The backwashing process is completed
(see chapter 4.1).
4.1.3 Due date of backwashing
After backwashing, adjust the indication but-
ton on the front of the device to the next
backwashing due date, as a reminder.
The JU-Control app, which is available free
of charge, reminds you on a mobile device
(mobile phone, tablet, etc.) when the device
needs to be backwashed.
Prerequisite: Download the JU-Control App
and create a user account.
This is how it is done:
1.
Download the JU-Control app from the
Google Playstore (Android) or the App
Store (iOS) and open it on your mobile
device.
2.
Create a user account (also possible in
advance via the website https://ju-con-
trol.app).
3.
Accept the data protection declaration
and click on the confirmation link in the
e-mail that follows.
4.
In the app: Create a location (save loca-
tion name and optional city and street).
5.
Scan the QR code on the unit with the
QR code scanner of the JU-Control
app.
The device is added. A reminder to
backwash will be automatically sent by
e-mail, SMS or push message, accord-
ing to the settings and the informa-
tion in the registration data of the user
account.
4.2
Conversions, changes
WARNING
Unauthorised conversions and
changes are forbidden for safety
reasons. These can impair the
functioning of the device, lead-
ing to leaks and, in the worse case
scenario, to bursting of the device.
