Initial operation

Avoid the wastewater pump(s) running dry for a longer period (>30 seconds) at all costs, it/they could become
damaged. Never switch wastewater pumps on if the system tank is not filled at least to the minimum level.

3.9.1 Initialising the control unit

• Connect the control unit to the mains supply, initialisation begins. The 4 LEDs come on in succession, an
acoustic signal is heard and the wastewater pump is switched on for a few seconds. Following successful
initialisation, the control unit is ready for operation, the green LED <1> comes on

3.9.2 Functional check

• Switch off the lifting station (see 4.5)
• Open the service opening <30> (Fig. [5], page 38)
• Fill the system tank fully with water. The water level must be up to
the opening of the access cover
Re-connect the control unit's power supply (plug in mains plug),
•
the control unit is initialised (see 3.7.1). The functional check is
has been successful if the following procedures are performed as
described:
– Level alarm is triggered, the Alarm LED <2> flashes red, an acoustic signal is heard and the wastewater
pump begins to evacuate the system tank
– Once the level falls below the alarm level, the alarm LED <2> goes out and the two orange LEDs
(level <3> and pump operation <4>) come on until the system tank has been evacuated by the wastewater
pump
– Visual inspection: The system tank may only contain a few centimetres of water when the wastewater pump
no longer runs
• Screw the service opening <30> (Fig. [5], page 38) down again, the lifting station is ready for operation
