Maintenance tasks

CAUTION
Inlet and outlet pipes must be emptied and pressure-less before work is started. The fill level in the system tank
must be located below the fixing level (pump flange) of the pumps.
CAUTION
Risk of material damage!
Pump must not dry run.
The batteries must have an adequate voltage reserve to ensure the readiness for operation of the backwater flaps during
a power failure. Under normal intended use conditions a voltage of 16V is sufficient until the next specified maintenance.
The voltage is given in the control unit menu, under "Current measured values".
Prepare maintenance
Check whether backwater is present (display on the control unit). If yes, maintenance cannot be carried out.
Carry out an electrical check of the system.
Ensure that there is no afterflow of wastewater.
Press the "Manual operation" button to pump away residual water.
Use the "manual operation" button to close the flap(s).
Switch off the control unit and secure against switching on
7.5 Maintenance of the backwater components
Dismantle and clean the lockable cover, flap(s) and slide-in flap housing(s)
Clean the interior in the area of the flaps
Coat the seal of the lockable cover and the slide-in flap housings' contact surfaces with the tank with KESSEL high-per-
formance grease (art. no. 681001)
The contact surfaces between the locking lever and flaps can also be coated with KESSEL high-performance grease (art.
no. 681001).
Re-install the slide-in flap housings and flaps. Make sure that the lockable cover is in the "CLOSED" posi-
tion. Also coat the lever on the underside of the lockable cover and its contact surface on the flap with
KESSEL high-performance grease.
Install the lockable cover. If backwater events have occurred since the last maintenance, dismantle the pump and expose
the ventilation opening. Then re-install the pump.
Switch on the control unit again. Use the Manual operation button to re-open the flap(s). Check the remaining battery volt-
age, as described above, via the control unit, replace the batteries if necessary.
