Connecting
For a single-phase version: see the diagram. Use the control panel with the condenser and the
switch.
Protection
Each deep well pump has built-in, manually resettable overload protection and automatically rever-
sible overheating protection.
Check direction of rotation
Check the correct direction of rotation. The right direction is the one that gives the maximum height
with the same amount of water absorbed.
Maintenance
Make sure the pump is disconnected from the power supply or the mains switch is off before it is
serviced.
10 cm pumps do not require routine maintenance.
Regularly check the vibration and power consumption.
Decreasing pressure can result from pump wear. Increased power consumption may result from
abnormally high friction in the pump or in the engine.
CAUTION!
The pump contains rubber parts that are used more quickly with oil.
Troubleshooting
Possible causes and solutions.
The pump does not press the water
• The water level has dropped. Wait until the water level is restored.
• No power, manual switch is off. Find the problem and turn the manual switch back on.
• The thermal fuse is released. After the engine cools down, it automatically switches back on.
• Check whether valve is clogged.
• There is sand in the pump. Lift the pump and repair it.
Reduced power and pressure
• There is sand in the pump. Lift the pump and repair it.
• The system was clear. Locate the leak and repair it.
• The pump is worn out. Lift the pump and repair it.
The pump switches too often on and off
• The float switch is probably switched on (the pump is more powerful than the drainage of the well).
Reduce water consumption.
• Excessive power consumption. Mechanical failure. Lift the pump and repair it.
• The liquid temperature is too high. The built-in thermal fuse is activated.
Repair
DANGER!
Only qualified service personnel can repair the electrical device.
If the pump needs repair, it must be sent to the nearest service facility. Look for the warranty guide
for the address.
1. IMPORTANT SAFETY INSTRUCTION
Read the instruction manual attentively before use.
Carefully remove the tool and any accessories from the box. Do not discard any of the packaging
materials until all parts are accounted for.
Keep the product in a dry place.
Read all warnings and instructions attentively. Failure to follow all warnings and instructions listed
below may result in electric shock, fire and/or serious personal injury.
Read operator`s manual carefulle. Learn its applications and limitations, as well as the specific
potential hazards related to this power tool. Following this rule will reduce the risk of electric shock,
fire, or serious injury.
Check whether the available power supply parameters correspond to the voltage parameters speci-
fied on the tool.
Check whether the power tool and connections are not damaged.
Connect the power cord to the outlet only when the tool is switched off.
Switch on the tool prior you place it on the workpiece.
Take all safety measures to reduce a risk of electric shock. Avoid body contact with earthed or
grounded surfaces, such as pipes, radiators, ranges and refrigerators.
Sudden temperature changes may result in water condensation on live parts. Prior to use: Let the
power tool reach the workplace room temperature.
Do not use machines, tools and recommended accessories for any than intended purposes!
Clamp the workpiece safely. Secure the workpiece to be drilled in a vice or witch clamps to keep it
from turning as the drill bit rotates.
Dress properly. Do not wear loose clothing or jewellery. Loose clothes, jewellery or long hair can be
caught in moving parts. Wear safety shoes and gloves. Contain long hair.
Should dust, chips and sawdust result from activity or should you work above your head, always
wear safety goggles and dust mask, where appropriate.
While impact drilling, wear suitable ear protective equipment.
While working on ladders, scaffolding or upper floors, always stand on a film base.
Do not expose power tool to rain or wet conditions. Do not immerse the tool into water.
When operating a power tool outdoors, use an extension cord and other accessories suitable for
outdoor use.
Do not operated power tools in explosive atmospheres.
When the tool is handed over to the third person, the instruction manual shall always be included.
The power tool can be repaired only by a qualified specialist and with the original spare parts.
WARNING!
Do not use a power tool while you ar tired or under the influence of drugs, alcohol or
medication. A moment of inattention while operating power tools may result in serious personal
injury. Do not use the power tool in any of the following situations.
Keep the power tool out of reach of children.
Store idle power tools in the original package in a safe place and out of reach of children.
Disconnect the power cord from the power outlet before making any adjustments, changing acces-
sories, or storing power tools.
Do not abuse the cord. Never use the cord to carry the charger. Do not pull the cord to disconnect
the power tool from the power source.
When working: Do not let the motor stop if the power tool is loaded.
Keep the workplace clean and tidy. A messy workplace increases a risk of injury!
Do not assume unusual body positions while drilling.
3. MACHINE DESCRIPTION
Start-up
We recommend installing a check valve on the transport side to avoid water shock.
Be careful not to damage the power cord when the pump is discharged into the well.
Fasten the power cord to the water pipe every 3 meters.
Place the pump in a tank or reservoir
The tank or reservoir must be large enough, not to turn off the pump too often (see operating limits).
Drain cable
If the pump is connected with a plastic outlet, it must be secured with a plastic or steel cable that is
attached to the pump retainer ring.
Well placed
Ensure that the pump does not touch the bottom of the well, but fully immersed in the water.
For floating types, leave at least 30 cm from the bottom of the well.
Make sure the pump does not dry if you have the chance of lowering the water level.
Dry operation can cause serious damage to the pump bearings.
Never test the pump dry.
• Use only a flexible plastic or rubber strap. Using a smaller diameter diaphragm makes the pump
too heavy.
Larger scallops can be used, no effect on pump performance.
• If there is no elastic slag, steel or plastic tubing is right. The pump must be connected to the rigid
pipe with a flexible tubing of at least 2 meters.
• When you turn off the pump, which is less than 5 meters below the water, the pump drains the
water from the scum.
• At a deeper depth, the pump blade locks and the water does not return, which may lead to freezing
of water in the winter.
• If it is not possible to protect the pump from the winter frost, a drain valve should be installed not
far from the outlet of the pump to drain the pipe.
• When using the pump, do not increase the water pressure by clamping the pipe or by attaching an
adapter that operates with a smaller water flow than the nominal pump performance.
• If the water pressure is greater than the pump pressure, the load on the rubber parts increases and
is therefore used more quickly. In this case the pressure must be reduced immediately.
• Always check the water quality while using the pump. If the water is muddy, turn off the pump and
check its location in the well.
• If the water contains sand or small stones, the internal water flow area of the pump will be dama-
ged.
Electrical connection
Verify that the voltage and frequency indicated on the product data sheet match the same
network values.
The installer must ensure that the electrical system is properly grounded.
Make sure the electrical system is equipped with a 30mA FI relay.
