7.5 Test run Before the lifting unit starts in automatic mode, conduct a test run. A test run checks the
proper functioning of the unit.
✓ Lifting unit installed.
✓ Floor drain or cover plug are removed.
1. Activate the lifting unit: Insert plug into socket.
⇒ Wilo-DrainLift Box... E/BOX... D : Lifting unit is in automatic mode.
⇒ Wilo-DrainLift BOX... DS : Check operating mode of the switchgear. The switchgear
must operate in automatic mode.
2. Open the shut-off valve on the inlet and discharge sides.
⇒ Collection reservoir is filled slowly.
3. Lifting unit is switched on and off using the level control.
⇒ To conduct a test run, complete two entire pumping procedures.
⇒ When pumping out, the pump must not start slurping operation.
Wilo-DrainLift Box... E/BOX... D : If slurping operation lasts longer than 1 s, readjust
the length of the float switch cable.
Wilo-DrainLift BOX... DS : If slurping operation lasts longer than 1 s, adjust the
switchgear’s follow-up time.
4. Close the gate valve in the inlet.
⇒ The lifting unit must be activated because there is no more fluid flowing in. If the
lifting unit switches on again, the non-return valve is leaky. Contact customer ser-
vice!

▶ Lifting unit operates in automatic mode.
Following a successful test run, the floor drain or the cover plug must be put back on!
7.6 Follow-up time The follow-up time is pre-set at the factory to 3 seconds. The follow-up time can be ad-
justed as required:
• Increasing the usable volume per pumping process.
• Extensive suction of settling sediments on base of tank through integrated depth suc-
tion.
• Slurping operation for avoiding pressure surges.
To set the follow-up time, read the installation and operating instructions for the
switchgear!
CAUTION! Pay attention to the operating mode if the follow-up time is changed. The
operating mode indicates the activation period and the downtime!
