2.1. General instructions
Signs used to mark instructions in this manual
Safety instructions in these operating instructions,
which, if not observed, could cause a danger for persons
are marked with the general symbol in accordance with
DIN 4844-W 9.
Warnings against electrical voltage are marked with
the safety symbol in accordance with DIN 4844-W 8.
2.2. General Safety Precautions
General regulations and guidelines not mentoined in the
safety warnings retain their validity.
These operating instructions contain basic instructi-
ons, which have to be adhered to during installation, ope-
ration and maintenance. These operating instructions
must be read from mechanic and the operator before in-
stallation and operation of the pump and have to be kept
available at the operating place of the machine/unit at all
times. Persons who are not familiar with the operating in-
structions shall not use this product.
Children and adolescents under age 16 shall not use
the pump and must keep away from the machine/unit
while it is operational.
The unit must be installed from a technical experien-
ced plumber.
The working area has to be closed off expediently
and must adhere to local workplace regulations.
Always use personal safety equipment such as safety
boots, rubber gloves, safety glasses and helmet.
Make sure that the emergency exit from the workpla-
ce is not barricaded.
To prevent suffocation and poisoning caused by
venomous gases, make sure that enough oxygen exists
at the workplace.
Never work alone at the unit.
Make sure that required like aids like lifting ramp is in
a regular and reliable condition.
If you have to work with welding tools or electric tools,
make sure that there is no explosion hazard.
Immediately after repair or maintenance work, all sa-
fety and protection equipment must be reinstalled and
placed in function again.
The operator of the pump is responsible for third par-
ties within the work area.
Never put a hand or finger into suction inlet or di-
scharge of the pump while the impeller is rotating.
All other rules and regulations and local codes
covering health and safety must be observed. In
accordance with product liability law, we point out that we
shall not be liable for damages caused by the pump due
to non-observance of the instructions and guidelines set
forth in the operating instructions. The same product
liability are valid for accessories.
3. Applications and Technical Description
3.1. Applications
HOMA disposal units Sanistar are used for pumping
waste water, effluent or groundwater, containing sludge or
soft solids from rooms which are below the sewer level.
The pumps must not be used for pumping of liquids
containing great quantities of abrasive solids, like sand or
stones. Before the pumping of chemically aggressive
liquids, the resistance of the pump materials must be
checked.
3.2. Product description
Smell-tight and watertight complete lifting station with one
or two pumps. The lifting station consists of a collecting
tank with all necessary ports for the connection of inlet
pipe, discharge pipe, air vent and manual diaphragm
pump (see page 19 - 21).
The controllers incorporate contactors, a pc-board with
light-emitting diodes ( LEDs ) for indication of operating
condition and a level switch which, via a hose, is operated
by the liquid level in the collecting tank.
The LEDs indicate :
- Pump operation
- Phase sequence fault (three-phase only)
- Fault
- Alarm
A thermal switch incorporated in the motor windings will
protect the motor from overheating by cutting off the
supply to the pump via the controller.
A back-up accumulator maintaining the alarm signal in
case of supply failure is available as an accessory. The
accumulator is fitted inside the controller via a plug and
ensures that an alarm can be given within 15 hours after
the electricity supply has been switched off.
The accumulator is fully charged on delivery. The
charging time is approx. 100 hours. The accumulator is
automatically charged when the electricity supply is
switched on.
Note : Used up accumulators must be disposes of in ac-
cordance with local regulations.
Three-phase controllers incorporate a phase monitoring
function which does not, however, prevent the motor from
starting in the event of wrong phase sequence of the
mains connection.
In addition to the LEDs, the controller front cover features:
- Function selector with the positions: ‘Test’ (manuell
operation), ‘Aus’ (turn off)and ‘Auto’ (automatic
operation).
- On/off switch for built-in acoustic alarm.
Sanistar single station
When the liquid level in the tank reaches the start level,
the pump will start and run until the stop level is reached.
If the liquid level rises to the alarm level, an alarm is given
until the liquid level is lowered below the alarm level.
Sanistar twin station
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,
