- The motorized backwater
flap cannot fully close most
likely due to an obstruction
in its path.
- Levers on Ecolift cover
were not in correct position
when the cover was instal-
led
- Backwater has been detec-
ted but the motorized back-
water flap cannot close fully
(most likely a blockage).
Unplug control unit and disconnect
batteries. Remove Ecolift cover and
remove any obstruction. Reconnect
batteries and plug in control unit
Recommendation: inform your aut-
horized KESSEL customer service
partner
See User’s
Manual 010-844 (Sections 4.2.1)
- Close the emergency manual flap
lever. After the backwater occur-
rence is over attempt to remove
the blockage as described in this
manual.
Attention: check backwater flap
operation lever! In the case that
the motorized backwater flap can-
not fully close, the Ecolift will per-
form 3 flap closure attempts in an
effort to dislodge any obstruction
that may be preventing the flap
from fully closing. If any of these 3
attempts are successful, then the
Ecolift will return to normal operati-
on and no alarm warnings will
sound. If these 3 attempts are not
successful then an alarm will
sound – this alarm can be acknow-
ledged by pressing the correct but-
ton on the control unit. Allowing
wastewater to drain through the
Ecolift may also help dislodge any
obstruction. Pressing the flap clo-
sure button can test to see if the
flap can now fully close. In the case
that the obstruction has not been
cleared then the alarm will activate
again and the object will need to be
removed as discussed below.
The KESSEL control unit can self-diagnose problems that can arise during commissioning as well as operation of the Ecolift and aid
in correcting any problems.
