lems and the water could back-up. To pre-
vent back-ups, the inlet pipe must be vented
at its highest point. The ventilation pipe can
be connected into the tank ventilation.
ELECTRICAL
CONNECTION
Only qualified electricians may
carry out electrical works to the
pump or the controls.
Before carrying out any work, pull
out the mains plug and ensure that
the power supply to the unit cannot
be switched on again by anyone else.
ATTENTION! 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 ob-
served.
Observe the operating voltage (see the type
plate)!
The units have a level controller that switch-
es the pump on and off depending on the lev-
el of the water. An integrated alarm system
beeps if there is a malfunction, even if this is
only temporary.
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 con-
nected. 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 accordance
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).
Attention! Only slow-blow fuses or automat-
ic fuses with C characteristics 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 com-
pli 300) as otherwise backpressure may oc-
cur 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 automatically by
the control unit.
Redefining the switch-on level (not compli
300)
Shut down the system temporarily and set
the Manual-0-Automatic switch to "0". The
switch-on point can be adjusted via the "ana-
logue 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 switch-
ing off height but still lower than switch-
ing on height
- P3 on = Water level has reached switch-
ing 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 readjustment
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 ad-
justing screw another full turn clockwise and
submerge the float switch again.
Repeat this procedure until P3 is no longer
lit, then turn the adjusting 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 opti-
cally as well as acoustically. The standard
mains-dependent alarm system reports mo-
tor 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 potential-free
contact (terminals 40 and 41) on the circuit
board (in the plug in the case of compli 300).
The potential-free contact of the centralised
alarm can be loaded with a maximum of 5 A
/ 250 VAC. The contact opens after the fault
has been remedied.
Battery pack for alarm system (not compli
300)
The alarm device is mains-dependent in its
standard version, i.e. it is not possible to trig-
ger a high-water alarm in the event of a pow-
er failure. To enable the alarm device to work
even if there is a power failure, a recharge-
able battery pack must be used. Open the
transparent cover. Connect the battery pack
to the connection clip, and use the existing
cable ties to attach it to the intended position
(G1) on the PCB. The battery pack can sup-
ply the alarm system with power for about 1
hour in case of permanent alarm.
After return of the mains voltage, the bat-
tery pack is charged again automatically. An
empty battery is ready for operation within
approx. 24 hours. It is fully charged after
about 100 hours.
Check the function of the battery pack at
regular intervals! To do so, disconnect the
unit from the mains and trigger a high-water
alarm. The volume of the acoustic signal
must not become significantly quieter over a
period of several minutes. The service life is
about 5 years. Note the insertion date on the
battery pack and after five years the battery
pack should be replaced as a precautionary
measure.
Only use a 9V rechargeable battery!
If dry-cell batteries are used there
is a danger of explosion!
Time meter
An optional time meter can be fitted in
the control unit (not compli 300). To do so,
shorten the connections of the time meter to
approx. 8 mm and insert them into the four
sockets at location BSZ on the printed circuit
board. If there is no time meter indication
after switching on the unit again, rotate the
time meter through 180°.
Shutting down the internal alarm buzzer
Not compli 300. Remove the sealed jumper
(BRX1). To prevent the jumper from getting
lost, attach it to a pin of the two-pole pin con-
nector.
External alarm buzzer
Open the transparent cover on the control
unit.
An additional separate acoustic 12 VDC sig-
nal transmitter with a current consumption
of not more than 30 mA can be connected to
terminals "S+" and "S-". The internal alarm
buzzer can either be switched on or off.
