with the operating instructions for equipment. In general all maintenance work must be carried out while the equipment is not in operation.
The instructions for turning off the equipment contained in these operating instructions must be observed.
Pumps and units which carry hazardous materials must be decontaminated.
Immediately after completion of the work all safety and protection coverings should be reinstalled and / or switched on.
Please observe all instructions set out in the section on “Installation / commencement of operation”
before returning the machine to service.
2.7 Non-manufacturer modification and spare part production
Modifications or alterations of the machine are only permitted after consultation with the manufacturer. Original spare parts and accessories
authorized by the manufacturer ensure safety. The use of other parts can invalidate any liability of the manufacturer for consequential
damage.
2.8 Unauthorized usage
The safety of the delivered pump is only guaranteed by usage according to the section 1 – General - of the instructions. The listed maximum
ratings as per specification should under no circumstances be exceeded. The improper use of the pump, i.e. pumping of air or explosive
media is strictly forbidden.
Also, this waste water pump, as a fully automatic utensil may need supervision from time to time and ensure if left
inactive for long periods that the electrical supply to the pump is switch off.
3. Description
- The pumps
Drain Inox 50 MA
are fitted with a robust single– phase electric motor.
- The most important seal is a mechanical seal between motor and pump– body and also a rotating mechanical seal.
- All units have a 10m power supply cable with plug for 230V 50Hz single- phase.
- Other voltages are possible on demand. Please note the data printed on the type- plate.
- This pump must be connected to an earthed outlet.
- Do not lower or lift the pump by means of the power cable.
- A damaged power cable must be replaced immediately by a qualified electrician. Danger of personal injury by electrical
shock if operated with a damaged cable!
- If the pump is connected to an electric installation where an earth-leakage circuit breaker (CB) is used as an additional
protection, this circuit breaker must trip out when earth fault current exceeds 30mA.
- Any operation of the pump next to a swimming pool or garden pond is only permitted if the unit is installed in accordance
to local legislations.
It is strictly forbidden to swim while using the pump in the swimming pool.
- If in doubt consult a qualified electrician

Installation and commencement of operation
Before starting any work on the pump/motor make sure that the electric supply has been switched off and that it can
not be accidentally switched on.
Before installing and starting please check the waste water lifting unit for possible damages (i.e. during transport) to
prevent personal injury by electrical shock.
If the pump is installed stationary inside a shaft, the minimum dimension should be 450 x 450 x 450mm. The build- on float switch
could be
locked at a shaft wall. The float switch mounted at the pump must be able to work free. As the water level rises, the float switch
does too, the
pump starts working until a certain level is reached, when the float switch stops automatically. The height for turning on/ off
can be varied by
displacing the float switch cable in the fastening eye.
The function of the float switch can be verified by raising and lowering of the float switch. Pumps without float switch will start immediately
upon placing of the plug in the outlet.
To avoid damages of the pump hydraulics and seals, the pump must not run dry! Also it is forbidden to use the pump
against a closed valve.
