General safety instructions
ATTENTION! When using electric tools, the following fundamental safety measures must be taken to prevent electric shock, injury or fire.
Read all of these instructions before you use the electric tool, and store the
safety in-structions properly.
Service and maintenance:
Have your device repaired only by qualified experts and only with original
replacement parts. This ensures the continued safety of the device.
Working safely:
- Keep your work area orderly. A messy work area can cause accidents.
- Consider environmental influences. Do not expose electric tools to rain. Do not use electric tools in damp or wet envi-ronments. Keep the work area well lit. Do not use electric tools where there is a risk of fire or explosion.
- Protect yourself from electric shock. Avoid physical contact with earthed parts (such as pipes, radiators, electric stoves or cooling devices).
- Keep other people away. Do not let other people — especially children — touch the electric tool or its cable. Keep them away from the work area.
- Store electric tools safely when they are not in use. Unused electric tools should be kept in a dry, high or closed area, out of reach of children.
- Do not overload your electric tool. Work is better and safer within the performance range indicated.
- Use the right electric tool. Don’t use low-performance machines for heavy-duty jobs. Do not use the electric tool for purposes for which it was not intended. For example, do not use a portable circular saw for cutting tree branches or logs.
- Wear proper clothing. Do not wear loose clothing or jewellery, as they can get caught in moving parts. When working outdoors, wear slip-resistant shoes. Wear a hairnet over long hair.
- Use protective gear. Wear safety glasses. Wear a breathing mask during work that creates dust
- Connect the dust extraction equipment. If there are connections to dust extraction and collection equipment, make sure that they are connected and properly used.
- Do not use the cable for purposes for which it was not intended. Never use the cable to pull the plug from the socket. Protect the cable from heat, oil and sharp edges.
- Secure the work piece. Use clamps or a vice to hold the work piece firmly. They will hold it more securely than your hand can.
- Avoid abnormal postures. Make sure to stand securely and always keep your balance.
- Maintain your tools with care. For better and safer work, keep cutting tools sharp and clean. Follow the instructions for lubrication and changing tools. Regularly inspect the electric tool’s connection cable, and if it is damaged, have it replaced by an authorized expert. Regularly check extension cords and replace them if they are damaged. Keep the handles dry, clean and free of oil and grease.
- Pull the plug from the socket. When not using the electric tool, before maintenance or when changing tools, such as saw blades, drills and cutting bits.
- Do not leave any tool keys inserted. Before switching on, check to see that keys and adjustment tools have been removed.
- Avoid unintentional activation. When plugging the tool in, make sure that the switch is turned off.
- Use outdoor extension cords. When outdoors, use only extension cords that are approved and appropriately marked.
- Be alert. Pay attention to what you do. Approach your work sensibly. Do not use the electric tool when you are distracted.
- Check the electric tool for damage. Before using the electric tool, you must inspect safety equipment or slightly damaged parts carefully to ensure that they work properly and as intended. Check to see that the moving parts operate freely and don’t stick, and to make sure no parts are damaged. All parts must be mounted properly and meet all the conditions for ensuring trouble-free operation of the electric tool. Damaged safety equipment and parts must be properly repaired or replaced by a professional facility, unless otherwise indicated in the user manual. Damaged switches must be replaced by a customer service facility. Never use an electric tool whose switch cannot be turned on and off.
- Caution. Using other insertion tools and accessories may cause injury.
- Caution. Pump can only be used on pipes where fittings can be connected properly
- Have your tool repaired by an electrical expert. This electric tool meets applicable safety requirements. Repairs must be made only by an electrical expert using original replacement parts. Otherwise accidents many occur.
- Caution. The pump is suitable to carry out cold washings, it can work at a temperature above 35°C for a maximum period of 60 minutes. In any case the washing solution must not exceed the temperature of 50°C.

Operatiing
-
Cut water pressure. Disconnect water supply.
-
Prepare the proper and suitable chemical product.
-
Choose the appropriate ROTHENBERGER descaler and dilute it in water as indicated on the descaler bottle.
-
Fill the tank with sufficient descaling solution to ensure that the pump rotor housing is submerged during use.
Attention! The pump is suitable to carry out cold washings, it can work at a temperature above 35°C for a maximum period of 60 minutes. In any case the washing solution must not exceed the temperature of 50°C! -
Separate the water inlet and outlet of the installation.
-
Connect one pump hose to hot water outlet, and one to the inlet.
-
Connect the power cable to a suitable 230 Volt single phase supply.
-
Open the Tank cap.
-
During use, the tank cap must be taken off, to allow the passage and elimination of the gas evolved during descaling. Check that the foam level does not exceed the maximum filling level. During descaling, check that the height of the foam forming inside the tank does not exceed the maximum filling level!
-
Switch on the pump.
-
Only ROCAL 20: By using the pump equipped with FLOW REVERSER it is possible to attack scale from both entries of the circuit. Actuate the flow reverser several times to attack the cap in both directions. By attacking scale from both sides it is possible to clean piping which is almost totally obstructed and descaling time is considerably reduced.
-
Only ROMATIC 20: By using the automatic pump equipped with FLOW REVERSER it is possible to attack scale from both entries of the circuit, with the possibility to programme the duration of descaling and the flow reversion time. By attacking scale from both sides it is possible to clean piping which is almost totally obstructed and descaling time is considerably reduced.
-
Scale removal can be considered complete when bubbles no longer form in the return pipe and the solution is still acid.
-
Attention! Once descaling is ended, do not leave the descaling liquid in the tank!
-
To eliminate the acid solution, lose hold inlet and outlet nuts and wait to the liquid leaves. Beware with the residual acidity, in order not to damage the pavement or other surfaces.
-
Once the antiscale treatment is finished, a neutralizing washing for the residual acidity is required with the ROTHENBERGER Neutralizing powder. To neutralize the descaling solution, pour the appropriate neutralizer into the tank, and dilute according to the indications mentioned on the neutralizer bottle
-
Empty the tank.
Rinsing the unit:
- In the descaler pump tank which is now empty, dilute the neutralizer with water (according to the indications mentioned on the neutralizer bottle).
- Connect the hoses as previously
- Start the pump and run this solution for a few minutes.
- Prime the unit and rinse with clean water (20 to 30 litres water) to eliminate any product residue.
Important! Colour change from red into yellow-orange will indicate that the descaling capability is exhausted! If the pump is not used for a period of time, wash out the pump after use by circulating clean water through it. Attention! The tank must be empty at all times and cleaned to prevent damaging the motor! Our equipment’s are constructed with high quality acid resistant materials and submitted to severe operating tests. Follow the above instructions to avoid any operating or servicing problems.
