8 Commissioning
NOTE! The unit may only be commissioned if the applicable local regulations
and requirements (e. g. VDE specifications) and all connection specifications
have been fulfilled.
CAUTION! Risk of damage!
The transport securing mechanism blocks the function of the floater. There
is a risk of the unit overflowing. Before commissioning the condensate lifting
unit, the transport securing mechanism (Fig. 1, item 9) must be removed in
order to ensure that the unit functions properly. Pull out the two plastic clips
on the left and right hand sides of the device to remove them. When pulling
out the transport securing mechanism, hold the device steady with your
other hand.
8.1 Functional check
• Plug in the mains plug.
• Fill the unit with clean water and check that the pumping sequence starts when
the water reaches the cut-in level (Fig. 2, item B).
• Check that the pumping sequence stops as soon as the water level reaches the
cut-off level (Fig. 2, item A).
To check the unit's alarm function, fill it with clean water until the water level
reaches the alarm level (Fig. 2, item C) and the alarm switch is triggered.
NOTE! In order to avoid increased running noise and protect the unit, there must
be no dirt in the condensate lifting unit.
9 Maintenance
Have maintenance and repair work carried out by qualified specialist person-
nel only!
DANGER! Risk of fatal injury!
There is risk of fatal injury due to electric shocks when working on electrical
equipment. The device should be electrically isolated and secured against
unauthorised switch-on before any maintenance or repair work. Damage to
the connection cables should always be rectified by a qualified electrician
only.
NOTE! For safety reasons, it is not possible to disassemble the motor unit of the
condensate lifting unit.
