GENERAL SAFETY WARNINGS
Warning!
- Read all safety warnings and all instructions.
- Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
- Save all warnings and instruc-tions for future reference.
- The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
- Work area safety
- a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
- b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
- c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
- Electrical safety
- a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
- b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators.
- There is an increased risk of electric shock if your body is earthed or grounded.
- c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
- e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
- f) If operating a power tools in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
- Personal safety
- a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
- b) Use personal protective equipment.
Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. - c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
- d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
- e) Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations. - f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
- g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used.
Use of dust collection can reduce dust-related hazards.
- Power tool use and care
- a) Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which it was designed. - b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
- c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
- d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
- e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
- f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. - g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
- h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
- a) Do not force the power tool. Use the correct power tool for your application.
- Service
a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure the safety of the power tool is maintained.

SPECIFICATIONS
OPERATION
General information
- These instructions are designed to ensure the correct installation and best use of our automatic constant water pressure assemblies.
- If you have any doubts, please consult your specialist dealer.
- The assemblies are completely silent and are designed to provide an auto-matic supply of clean water to one or two dwellings.
- If water consumption is more than 1 l/m, the pump will operate continuously. Our units are constructed with the finest materials and are subjected to the most rigorous hydraulic and electrical controls, painstakingly verified.
- By strictly following the instructions for installation and use of the pump and paying careful attention to the wiring diagrams, you shall avoid the possibility of overloading the control circuit or of any other problems associated with misuse, for which we can accept no responsibility.
- When the pump reaches maximum pressur,e the unit automatically switches the pump off. Unit selection must take into account the fact that the differential must be over 0.7 kg.
Installation
The Controller has a 1*BSP threaded male fitting which can be screwed directly into the pump, and 1* BSP female for connection to discharge pipework. The assembly should be protected from the risk of flooding and installed in a sheltered place but well-ventilated place.
If the pump to which the Controller is fitted is directly connected to the mains supply, it must be remembered that the incoming pressure must be added to that provided by the pump. Total pressure may never exceed bar.
It can be fitted to any installation that has sufficient feed flow.
Discharge pipework assembly
The discharge pipework diameter should be equal to or larger than that of the pump discharge. It should not rest against the pressure unit and should be checked for watertightness.
We recommend the use of a flexible anti-vibration hose on the discharge, as direct connection to rigid pipework could cause damage to the Controller.
No check valve needs to be installed.
Electrical connection
- Nominal pump current should be no higher than 10 A and the maximum motor power (P1) should never exceed 1.1 Kw.
- Ensure that all the connections between the electronic circuit and the power and motor cables are properly made.
- To ensure correct connection.
- The protection of the system should be based on a differential switch (1 fn = 30mA). The supply cable should comply with EEC standards (2) or be of type H07 RN-F as per VDE 0250.
Controls prior to start up Before first starting the pump ensure:
- That the grid voltage and frequency match those featured on the specification plate.
- The pump shaft turns freely.
- The pump body is completely full of water-fill by unscrewing the corre-sponding priming plug.
The pump should never be operated dry.
Start-up
- Open all gate valves in the suction and discharge lines. Switch on the power and the pump will start automatically. While doing so, leave the discharge tap open to bleed any air that may be in the system. Then, close the tap and the assembly will shut down when it reaches maximum pump pressure.
- If the pump is not properly primed or this is no water supply, it will shut down after 10 seconds.
- Once the water level is recovered and the pump has been properly primed, repeat the Startup operation, this time holding in the red reset button for a few seconds.
- If the assembly does not operate, does not produce pressure or does not shut down, try to discover the cause of the problem consulting the troubleshooting guide provided below.
MAINTENANCE & FUNCTIONS
Possible favlts, causes and solutions
- The assembly does not shut down.
- The motor operates but provides no flow.
- The pressure is not sufficient.
- The assembly is constantly stopping and starting.
- The assembly does not start.
Maintenance
Our Controller require no specific maintenance. Notwithstanding, we recommend that they be emptied when temperatures are low and there is a risk of freezing or if the unit is not to be used for a long period of time. If the unit is not to be used for a very long period it should be cleaned and stored in a dry, well-ventilated place.

Bom dia caríssimos, a minha bomba só aspira água sem o contralador montado, segui todos procedimentos necessários, inclusive troquei o controlador
Why does my pump only draw water when the controller is not installed, even after replacing the controller?
If your pump works alone but fails when the TOTAL TWPS101 controller is installed, the issue is likely related to air leaks, priming, or pressure settings. Since you have already replaced the controller, please check the following based on the manual's troubleshooting guide:
If the motor operates but provides no flow (Fault #2 in the manual), verify that the total head height is not exceeding the pump's capacity and that no gate valves are closed.

Puedo instalar la bomba con la flecha iundicadora de flujo hacia abajo? esto debido a que el flujo normal de agua va en ese sentido de arriba hacia abajo.
Can I install the pump control with the flow indicator arrow pointing downwards if the water flow is from top to bottom?
Based on the instruction manual for the TOTAL TWPS101 Automatic Pump Control, the device is designed with a specific Water Inlet (2) at the bottom and a Water Outlet (1) at the top (as shown in the Components List on page 5). The internal mechanism, including the check valve and pressure sensors, typically relies on a vertical orientation with the flow moving upward.
Installing the unit with the arrow pointing downward (upside down) is generally not recommended for the following reasons:
If your water flow is strictly top-to-bottom, you should use piping (such as a U-bend) to ensure the water enters the bottom inlet of the controller and exits through the top outlet in the direction of the arrow.
