ENGLISH
Emergency drainage connection, DN 50,
vertical
This inlet is used to connect a diaphragm hand pump.
Open the pipe connection at the marking using a hole saw.
Then deburr the edges.
Put the plug-in seal, 58/50, into place.
Push the inlet pipe, with an external diameter of 50 mm, into
the tank through the plug-in seal. The distance from the bot-
tom of the tank must be at least 50 mm.
Fix the diaphragm hand pump to the wall in an easily accessi-
ble position. Connect it to the pushed-in pipe and then connect
the pressure pipe to the diaphragm hand pump. Here, too, the
pressure pipe must be looped over the local backup level.
Additional inlet, DN 50, horizontal
Using a hole saw, open the additional inlet by cutting along the
pre-cut groove. Deburr the edges.
Put the plug-in seal, 58/50, into place.
Push the inlet pipe, with an external diameter of 50 mm, into
the tank through the plug-in seal.
NOTICE! The pipes that connect to the low-level inlets on the
side of the unit must be fitted with a bend, as close to the unit
as possible. The pipe invert of this bend must be at a height
of at least 180 mm above the floor on which the unit is fixed.
Air pockets in the connecting pipe can cause run-off problems
and the water could back-up. To prevent back-ups, the inlet
pipe must be vented at its highest point. The ventilation pipe
can be connected into the tank ventilation.

ELECTRICAL CONNECTION

NOTICE! Only qualified electricians may carry out electrical
works to the pump or the controls.
WARNING!
Before carrying out any works: disconnect the pump and the
controls from the mains and take steps to ensure that they
cannot be emergized again.
NOTICE! Never put the mains plug in water! If water gets into
the plug, this can cause malfunctions and damage.
The standards applicable in each case (e.g. EN), the country-
specific regulations (e.g. VDE in Germany), and the regulations
of the local supply network operator must be observed.
Observe the operating voltage (see the type plate)!
The units have a level controller that switches the pump on and
off depending on the level of the water. An integrated alarm
system beeps if there is a malfunction, even if this is only tem-
porary.
If the pump overheats, the motor cuts out due to the winding
thermostat. After the thermostat has switched off the system,
pull out the mains plug before remedying the fault, since the
device can switch itself on again automatically if the power is
still connected. A direct malfunction message is not generated.

Alternating current (AC) units
Only connect the pump to electrical sockets that have been
installed properly in a dry room, above the backup level, in ac-
cordance with the regulations, and are fitted with at least a 16
A (delay) fuse.
Three-phase current units
For the electrical connection of the sewage disposal unit, a
five pole CEE power socket is required. This must be located in
a dry room above the backup level (3/N/PE~230/400 V).
NOTICE! Only slow-blow fuses or automatic fuses with C cha-
racteristics are to be used as pre-fuses for the pump.
Installing the control unit (not compli 300)
Only operate the control unit in dry rooms above the backup
level, and keep the housing closed at all times. The control unit
must be easily accessible to enable it to be checked at any time.
High humidity and condensation can destroy the controls!

Switching levels

The switch-on and switch-off points have been factory set for
the standard inlet height for the various units.
If you select a different inlet height, then you must redefine the
switch-on point (not compli 300) as otherwise backpressure
may occur in the inlet.
The other switching points for the alarm (+2 cm) and, in the
case of duplex units, peak load (+4 cm) are then reset automat-
ically by the control unit.
Redefining the switch-on level (not compli
300)
Shut down the system temporarily and set the Manual-0-Au-
tomatic switch to "0". The switch-on point can be adjusted via
the "analogue evaluator K1" module on the right-hand side in
the control unit. Remove the transparent cover of the module
temporarily.
On the analogue evaluator there are three LEDs, labelled P1, P2
and P3.
– P1 = Diagnosis function
– P2 on = Water level higher than switching off height but still
lower than switching on height
– P3 on = Water level has reached switching on level
Fill the collection chamber with water up to the bottom edge of
the inlet opening. Only P2 should be lit. If P3 is also lit, a read-
justment must be made.
Turn the small adjusting screw beneath P1, giving it one or two
full turns clockwise. Then take the float switch, submerge it
below the switch-off point in the chamber and allow it to float
up again. If P3 is still lit, give the adjusting screw another full
turn clockwise and submerge the float switch again.
Repeat this procedure until P3 is no longer lit, then turn the ad-
justing screw carefully back in the anticlockwise direction until
the exact point where P3 lights up again. The switch-on point
has then been set.
Alarm system
Malfunction messages are given both optically as well as
acoustically. The standard mains-dependent alarm system re-
ports motor faults in the pump (red LED, not AD 00 or compli
300). At the same time a built-in acoustic alarm sounds. This
acoustic signal can only be turned off by remedying the fault or
by totally deactivating it.
If an acoustic signal would be inappropriate at the installation
site in question, an alarm signal can be relayed via the poten-
tial-free contact (terminals 40 and 41) on the circuit board (in
