Assembly And Installation - Wilo Drain-Lift KH 32-0,4 Instrucciones De Instalación Y Funcionamiento

ENGLISH
The motor coil is protected by an overload safety
device which automatically switches off the motor if
exposed to an above-average level of stress. After
the motor has cooled down, it is automatically
switched back on.
The in-built booster relay (fig. 2, pos. 4) switches the
unit on and off, depending on the level.
The activated carbon filter integrated into the unit
(fig. 2, pos. 5) enables airing and ventilation to take
place directly in the installation room or by means of
an aeration pipe on the roof which should be connec-
ted separately. In order to prevent the collection tank
from overflowing through the activated carbon filter in
the event of pump failure and an increase in the level
of liquid, an additional flap trap (fig. 2, pos. 6) has
been added. The drain connection also contains a
flap trap (fig. 2, pos. 7).

5. Assembly/Installation
5.1 Assembly
– The unit should be installed in a frost-free room.
– The assembly area must be horizontal and flat.
– The lifting unit and the electrical connection (plug)
must remain accessible for maintenance even after
assembly.
– Remove covering cap (fig. 2, pos. 8) using the
tommy bar (fig. 2, pos. Z) and pressing the 3 spring
hooks (at side and front).
– The lifting unit is connected directly to the toilet
bowl with a horizontal waste connection pipe (in
accordance with DIN EN 37).
– The remaining drainage areas (e.g. wash basin,
bidet or shower) are connected to the additional
supply channels. The union nut, pressure ring and
existing angle collar should then be pushed over
the supply channel (outer-Ø 40 mm, commercially
available PVC pipe).
Push the PVC pipe into the supply channel connec-
tion pipe and screw the union nut tightly on to the
inlet connection pipe.

The unused inlet opening must be locked with the
cowl provided:
– Push the pressure ring on to the cowl
– Slide on the seal (cross section form: three-sided)
with the wide edge pointing to the pressure ring
– Lay the cowl in the union nut and screw on to the
supply channel opening.
The additional side supply channels
ATTENTION!
(DN 40) must be positioned above the
highest possible water lever (180 mm).
For this reason the construction level
(base) of the shower basin must lie
at least 180 mm higher than the
construction level of the mini lifting
unit (fig. 3). The shower surface may
be reduced to 110 mm above the
construction level when installing
Viega-domoplex discharge fittings,
when the distance between the lifting
unit and the shower is equal to or
larger than 1,200 mm.
– The flap trap (fig. 4) is pushed into the lower supply
channel opening as far as the limit stop in such a
way that the trap is open to the cistern. Then push
in the supply pipe as described above (use of trap
not permissible in Germany).
– Shorten the pressure hose to the desired length,
push it into the desired position on the hose
connection pieces and secure with the clamp.
– Push the conical end of the pressure hose as far as
possible onto the pressure pipeline (DN 25 or DN 32)
which should be connected on site and secure
against sliding with a clamp.
– It is recommended that a shut-off device be instal-
led in the pressure pipeline. It must be suitable for
waste water containing sewage and should be
connected on site.
– Connect pressure pipeline (fig. 3, pos. 1, minimum-
Ø DN 25) upwardly onto the collector pipe.
– If the pressure pipeline runs horizontally off centre, it
must be laid with a loop when it comes out of the unit.
– Press on covering cap.
– In order to protect against possible reflux out of the
public channel, the pressure pipeline should be
formed as a "pipe loop". It must be placed over the
locally set reflux level (usually street level).
– If ventilation takes place through a vent connection
in the roof rather than through the activated carbon
filter which is integrated into the unit, the cap
