SAFETY INSTRUCTIONS
- MACHINES SUBMITTED : Powered with : Electric, Pneumatic, Petrol or Diesel engine.
- SYMBOLS : The words WARNING and CAUTION used in safety instructions, have the following
meanings :
WARNING indicates hazards or hazardous procedures which could result in serious injury or death ,
if the WARNING is not observed.
CAUTION indicates hazards or hazardous procedures which could result in injury or damage to
equipment if the WARNING is not observed.
- IMPORTANT RULES FOR YOUR SAFETY :
WARNING
The machine must not be modified without prior consent of the manufacturer. Use only original parts. If
modifications are made without prior consent of the manufacturer there is a risk of serious injury to the personal.
- These safety recommendations have been compiled from international safety standards.
Local regulations must also be checked and observed. Before using the machine, read carefully these
instructions and keep them in a safe place.
- Make sure that the signs about using, safety, and maintenance are always legible.
- The use of the machine is restricted to the applications specified in the product literature.
- Always change damaged parts immediately. Change wear parts in due time.
- SAFETY EQUIPMENT :
WARNING
The admissible sound level of 85 dB (A), can be exceeded because of the machine and/or the application. Long time
exposure to loud noise without ear protectors can cause permanent damage to hearing.
Long time exposure to vibrations can damage the hands, fingers and wrists. Do not use the machine if you are
experiencing discomfort, cramp or pain. Consult a doctor before working again with the machine.
- Always use approved safety equipment. The following safety equipment applies to operators and other
personnel in the immediate vicinity of the working zone.
- Safety helmet.
- Ear protectors.
- Dust mask in dusty environments.
- Protective gloves.
- Protective shoes.
- Goggles.
To avoid the risk of clothes being caught in the machine, avoid wearing loose-lifting clothes. If you have long hair,
cover it with a hair net.
- WORKING AREA :
WARNING
Do not use the machine in explosive environments.
Do not operate a machine powered by a petrol or diesel engine in poorly ventilated spaces. These types of engines
produce toxic gases which can cause serious health troubles.

-POWER SUPPLY :
WARNING
Make sure that the power supply equipment complies with the relevant safety requirements of the local and the
international standards.
- Electric machine : It must be ensured that the machine is connected to the voltage and the frequency
specified on the name plate. The power supply cable has to be properly sized. Check that the cable and the plug of the
machine are not damaged. Never switch off the machine by pulling the plug from its socket. Use the machine switch.
Keep the cable out of the moving parts of the machine.
- Pneumatic machine : Check that the compressed-air hose and the hose coupling are not damaged. Never
attempt to loosen a compressed-air hose which is pressurized. First switch off the air at the compressor and then leave
the machine running itself to discharge the hose after some seconds.
- Machine powered by petrol or diesel engine : Petrol has an extremely low flash-point and can be explosive
in certain situations. Keep away from all hot or spark-generating objects, do not smoke, when handling fuel. Wait until
the machine has cooled before filling the tank. Avoid spilling petrol or diesel on the ground.
-STARTING THE MACHINE :
CAUTION
Before starting make yourself familiar with the machine and make sure that the machine does not show any obvious
faults. Then start the machine according the instruction and spare parts catalogue.
-OPERATION :
CAUTION
Use the machine only for the purpose for which it is intended. Make sure you know how to stop the machine quickly
in the event of an emergency situation. Do not touch rotating parts during operation.
-MAINTENANCE :
CAUTION
Maintenance work must only be carried out by skilled personnel. Keep unauthorized persons away from the
machine. Do not carry out maintenance work while the machine is moving or the engine is running. Never use a
machine which is damaged.
-BE ALERT :
CAUTION
Always concentrate on what you are doing. Use common sense. Never operate the machine if you are tired or under
the influence of drugs alcohol or other substances which can affect your vision, reaction, ability or judgement.

GENERAL
The RL submersible drainage pumps are designed for pumping lightly contaminated water .
DESIGN
The heavy duty light weight aluminium construction includes a cooling jacket ensuring adequate motor cooling at all
times .
The pumps are in 'plug and pumping design' , with built-in full overheat motor protection .
The versions with level float switch allow automatic operation .
The unique cartridge type seal package can be easily replaced on site with only minimum downtime .
For demanding applications as in construction works and mining , the impellers are made for wear resistant Hi-Chrome
iron and all other components are rubber lined .
The impeller clearance is easily adjustable to compensate for wear .

Here is the combinations for the most common pumps . In case of special applications please contact us .
INTALLATION
The pump must not be used in an explosive / inflammable environment or used to pump inflammable
liquids !
- Route the cables so that connectors do not lie in the water. Consider the risk of electrical accident.
Never lift the pump by its power cable !
- Connect a discharge hose of approved pressure class.
- The discharge hose may be thrown off when the pump starts.
- No one must be allowed in the water, e.g. swimming pools, when the pump is running.
- Check that the pump is standing steady, or suspend it from its lifting ring.
- Check the direction of rotation, pointed by the starting kick arrow printed in the outer casing (anti-clockwise)
The pump will start instantaneously when it is connected to the power supply.
The pump may kick violently when it starts.
In case of wrong direction of rotation two phases should be inverted from the supply.

7
ELECTRICAL CONNECTION
Check that the details on the pump data plate match with the mains voltage and frequency.
The electrical installation must be carried out by a qualified electrician !
Local installation regulations must be followed !
Make sure that the pump is properly earthed. The earth conductor must be slightly longer than the phase conductors. If
the motor power cable is accidentally pulled off, the earth conductor must be the last conductor to be removed from the
terminals.
Never lift the pump by its power cable !
Pumps must be connected to an approved motor protection.
BUILT-IN MOTOR PROTECTION
Check that the pump is disconnected from the power supply before starting any work !
The pump's built-in motor protection switches off the contactor automatically if the motor overheats. Then, the fault
must be identified and corrected. After cooling to normal working temperature, the motor protection switches on the
contactor and the pump starts again.
