The controller of Sanistar automatically ensures an even
distribution of operating hours on both pumps by changing
the starting sequence after each pump stop.
When the liquid level in the tank reaches the start level,
one pumps is started. If the liquid level rises further, the
other pump is started as well. Both pumps will stop,
when the lowest stop level is reached.If the liquid level
continues to rise when both pumps are operating, an
alarm is given until the liquid level is lowered below the
alarm level.
The installation kit consists of a discharge connector, a
pipe and a non-return valve.

3.4. Operation Conditions
Please pay attention to the installation and operation
instruction manual of the installed submersible pump.
3.5. Explosive Environments
For operation of the pumps in explosive environments
only models with explosion-proof motors (Ex model) must
be used.
For each individual installation the explosion classifi-
cation (Ex-class) of the pump must be approved by the
localauthorities.
4. Warranty
Our warranty only covers pumps which are installed and
operated in accordance with these installation and opera-
tion instructions and accepted codes of good practice and
being used for the applications mentioned in these
instructions.
5. Transport and Storage
The pump station may be transported and stored in
vertical position. Make sure that it cannot roll or fall over.
For longer periods of storage, the pump should be pro-
tected against moisture, frost or heat.
6. Electrical Connection
6.1. General instructions
Before operation, an expert check must secure that
the required electrical protection measures exist. The
connection to ground, earthing, isolating transformer, fault
current breaker or fault voltags circuit must correspond to
the guidelines set forth by the responsible power plant.
The voltage required in the technical data sheet
must correspond to the existing line voltage.
Make sure that the electrical pin-and-socket connec-
tions are installed flood- and moisture-safe. Before start-
ing operation check the cable and the plug against dam-
ages.
The end of the pump power supply cable must not be
submerged in order to prevent water from penetrating
through the cable into the motor.
The electrical connection of the pump should be carried
out in accordance with local requirements.
The operating voltage and frequency are marked on the
pump and controller nameplates. Voltage tolerance: +6%
up to -10% of the voltage stated on the nameplates. Make
sure that the pumps of the pump station are suitable for
the electricity supply available at the installation site.
In case of a defect of the pump, a repair shall be carried
out only by the manufacturer or through an authorized
workshop. Modifications of the pump must be confirmed
by the manufacturer.
Controlb box and pump have to connect as shown in the
wiring diagram in the manual instruction of the pump.
The electrical connection must be carried out in accor-
dance with the marking on the cable to the controller.
Connect the units to the mains supply.
An external fault signal device can be connected to the
controller via the potential-free fault signal output.
Maximum load: AC 250 V, 5 A, AC 1.
Motor-Start
The motor of units are designed for direct-on-line (DOL)
start.
6.2. Electronic control box
The equipped electronic control box controls the operation
functions and announce failures which may be occure.
Operation switch (one of each pump)
Postion "Manu"
The pump operates, irrespective of the liquid level in the
tank. To stop the pump release the switch. The switch
turns into the position „Aus/Off“.
Position „OFF“
The pump is stopped.
Position "Auto"
Pump operation according to the liquid level in the tank.
Acoustic alarm switch
Position "On"
The built-in acoustic alarm is activated. Together with the
red LEDs “Alarm“and “Failure“ the built-in acoustic alarm
will start if the level of the medium is above the alarm
level. The alarm is automatically reset when the liquid
level has been lowered below the alarm level.
