Manufacturer: Madal Bal a. s., Průmyslová zóna Příluky 244, 76001 Zlín, Czech Republic. Version: 06/2025.

I. Characteristics – Purpose of Use

EXTOL CRAFT electric submersible pumps are designed for pumping clean and dirty water from wells or other water reservoirs for use in domestic gardens and similar environments. The pump is not intended for pumping water containing sand, gravel, larger stones, dense sediments, or sludge, nor for emptying cesspools or similar tanks (e.g., domestic biological wastewater treatment plants).

Forbidden Uses

• The pump is not intended to increase water pressure in the distribution system. It must not be operated with a restricted or closed water outlet as it lacks a pressure sensor to shut off the motor.
• The pump is not intended for pumping drinking water or other liquids used in the food industry.
• The pump is not intended for pumping liquids other than clean and dirty utility water. This also applies to aqueous solutions of corrosive substances (acids, alkalis, substances with oxidizing-reducing properties - e.g., bleach) or other chemicals.
• The pump must not be used for pumping clean utility water containing ice or water above 35°C.
• The pump is not designed for continuous long-term operation, e.g., for continuous pumping of water from a large reservoir.

II. Technical Specifications

¹⁾ The stated power input is achieved at the pump's limit load, as the motor's power input depends on its load, and the stated power input value is a certain expression of the motor's power. The rated power input is therefore lower than the power input at the pump's limit load.

²⁾ The flow rate depends on the head, as shown in the flow rate graphs (Fig. 3A to 3C). The lower the head, the greater the flow rate. The stated maximum flow rate is determined under ideal conditions, excluding factors that reduce it, to allow for comparison with other pump models. Flow rate/head also depends on the length of the discharge hose, where 10 m of horizontal discharge hose corresponds to approx. 1 m of head. Flow rate is reduced by hose connectors or fittings, as they have a smaller inner diameter than the hose. Flow rate also depends on the hose's inner diameter.

³⁾ The stated maximum head is independent of the maximum permissible immersion depth of the pump.

III. Components and Controls

Refer to Fig. 1 and Fig. 2 for component identification:

• 1. Float switch
• 2. Handle for carrying the pump and for suspending it in the pumped water
• 3. Float switch cable holder - for adjusting the float switch cable length
• 4. Hose connector for attaching the hose to the pump
• 5. Base with suction openings

IV. Pump Preparation for Use / Operation / Shutdown

WARNING

• Perform pump preparation with the power supply disconnected. Connect the pump to the power supply as the final step after preparing the pump for operation, following checks of the power cable insulation, float switch cable, float switch cover, and after placing the pump in the pumped water.

1. Screw the hose connector (Fig. 1/Fig. 2, Pos. 4) onto the water outlet thread of the pump. Before screwing the connector onto the thread, wind Teflon tape intended for plumbing onto the thread to seal the joint.
2. Connect the hose to the pump connector either via a threaded flange or by sliding the hose end with a tightened hose clamp onto the pump connector nozzle and then tightening the hose clamp. If necessary, the hose may need to be secured with several hose clamps. If using a threaded hose connection to the pump, seal the thread with Teflon tape for plumbing. Obtain the hose, flange, or hose clamp from a pump equipment store. The hose, hose flange, or hose clamp must be suitable for this purpose. The hose clamp must not be deformed to ensure proper hose attachment (tightening around the entire circumference of the hose fitted on the connector).
3. Secure the hose fitted on the pump connector properly by thoroughly tightening the hose clamp or the flange. Do not use pliers or excessive force to tighten the flange.
4. Securely attach the suspension rope (Fig. 5) to the pump handle (Fig. 1/Fig. 2, Pos. 2). The pump will be lowered into the pumped water by the rope.
5. Adjust the length of the float switch cable by pulling the cable in the float switch cable holder. This will determine the water level at which the pump motor shuts off.

Float Switch Operation Principle: The principle of the float switch is shown in Fig. 4 on a different pump model. The motor runs when the float switch is raised to the required water level relative to the set float switch cable length. When the float switch sinks towards the pump body due to the lowered water level, the motor operation is switched off. The float switch function is set so that at the maximum set float switch cable length, the water cannot be completely pumped out to protect the pump from running dry.

Verification of Float Switch Function: Test the correct operation of the float switch by immersing the pump in a container of water and manually moving the float to the upper position, then gradually moving it down. The pump must respond accordingly by turning on when the float switch is raised and the electric motor shutting off when it sinks.

Ensure that the float does not touch the pump before the electric motor stops, which is a protection against the pump running dry.

For proper float switch function, the distance between the float switch and its cable holder must not be too small, otherwise the pump motor may not shut off because the float switch will not have sufficient tilt towards the pump body, and the pump could run dry, which would damage it.

WARNING

• The pump must not be operated without water. Therefore, ensure that the float switch can move freely in the pump area and that the float switch is not secured in the upper position, intentionally or unintentionally. Otherwise, the pump will not shut off depending on the float switch cable length, and the pump could run dry, leading to damage.

CAUTION

• Information on forbidden pump uses is provided in Chapter I.

6. Before each use of the pump, check its condition, especially for damage to the plastic cover of the float switch, the pump body cover, and the insulation of the pump's power cable and the float switch cable.

The plastic cover of the float switch may be damaged due to mechanical impact, and the cable insulation may be cut or damaged by rodents. Damage to the power supply cable insulation can lead to electric shock or fatal injury!

Do not use the pump with such damage and ensure it is replaced with a faultless unit.

7. Slowly lower the pump, secured by the rope, into the water (Fig. 5) so that the pump is maximally submerged in the water relative to the water height, and at the same time, the maximum permissible immersion depth is not exceeded (see Table 1). The pump must not be lowered into the water by holding the power cable, but by the rope attached to the handle, as lowering the pump by the power cable can damage the seal around the cable at the point of entry into the pump and allow water to enter the electrical part of the pump, causing electric shock or fatal injury.

WARNING

• The intended/forbidden use of the pump is described in Chapter I. The pump must not be submerged in dense sediments settled on the bottom. If it can be expected that there is a layer of dense sediments, mud, sand, etc. settled on the bottom, the pump must not be lowered to the bottom, but must be suspended in the pumped water at a sufficient height above the bottom. At the same time, it must be considered that the operation of the pump will stir up the sediments on the bottom, so the pump must be suspended at a sufficient height above the bottom.

WARNING

• The pump is designed for vertical operation. Ensure that the pump does not tip over during lowering or operation, if applicable.

Before starting the pump, secure the hose end against whipping.

Before connecting the pump's power cable to the power supply, ensure that the voltage in the socket corresponds to 230 V ~50 Hz within the permissible voltage deviation of the distribution system and that the socket is equipped with a residual current device (FI) RCD with a tripping current of 30 mA or less. This residual current device must be installed in the fixed electrical wiring, approved by a qualified inspection technician.

Plug the power cable's socket into the live socket.

WARNING

• If the pump is not sufficiently submerged in water during operation, the pump's thermal protection may activate and shut off the motor due to insufficient cooling of the pump body by the surrounding water. If thermal protection is activated, disconnect the power cable from the power source, remove the pump by pulling the rope, and rectify the situation.

To stop the pump, always first disconnect the pump's power cable from the power supply and then remove the pump by pulling the rope. The pump must not be pulled by the power cable, see point 7!

WARNING

• If the pump is not used for a long time or if there is a risk of water freezing, disconnect it from the power supply and remove it from the pumped water.

SHUTTING DOWN THE PUMP

1. Immediately after use, rinse the pump with clean water by immersing it in a container of clean water and briefly connecting the pump's power cable to the socket to sufficiently flush the pump with clean water, as impurities may be present in the pump that could dry out in the pump after shutdown. Always disconnect the pump's power cable from the power supply before removing the pump.
2. After flushing the pump, disconnect the hose from the pump and let the residual water drain from the pump. Then store the pump in a place where there is no risk of frost (risk of residual water freezing in the pump) and damage to the power cable insulation by rodents.

WARNING

• Water must not freeze in the pump. Drain all water from the pump before storage. Do not leave it submerged in water if there is a risk of water freezing.

V. Principles of Operation and Safety Instructions

• Before using the pump, familiarize yourself thoroughly with its correct use and respect the limit conditions for its use.
• Connect the pump to a socket equipped with a residual current device FI (RCD) with a tripping current of 30 mA or less to protect against electric shock. This residual current device must be installed in a fixed electrical distribution system approved by an electrical installation technician with the necessary qualifications.
• Protect the power supply socket from moisture and flooding.
• If using an extension power cord, it must have the same internal cross-section as the pump's power cord (indicated on the cable insulation) to avoid current overload of the conductors. We also recommend that it has a rubber (rubber) insulation marked H07RNF or H05RNF, which is more resistant to mechanical damage than PVC insulation. The connection point of the extension cord with the pump's power cable must be protected against moisture and water ingress.
• After pumping chemically treated water from a swimming pool, rinse the pump with clean water, as pool water has corrosive effects.
• The pump must not be used if people or animals are in the water. During pump operation or if the pump is energized, avoid contact with the pumped liquid, conductive parts of the container, the pump, and/or the metal suspension chain, and ensure that other persons or animals do not come into contact with the pumped liquid, as electric shock may occur if the insulation of the pump's power supply, the float switch cable, or the float switch protective cover is damaged.
• Standard EN 60335-2-41 requires that the operating manual for submersible pumps includes information indicating the possibility of water contamination due to lubricant leakage.
• Prevent persons (including children) with physical, sensory, or mental disabilities, or lack of experience and knowledge, from using the appliance without supervision or instruction. Children must not play with the appliance.
• Prevent mechanical or thermal damage to the pump's power cable, the float switch cable, and the float switch protective cover and the pump.

AAA

• Wrap the contact point of the power cable with sharp or rough edges with protective material, e.g., fabric. If vehicles pass over the power supply, the supply must be placed in durable protection. Prevent thermal damage to the cable insulation.
• Before removing the pump from the pumped water, or performing service or maintenance work, disconnect the pump's power cable plug from the electrical power source.
• Never carry or suspend the pump by the pump's power cable or float switch cable.
• Any interventions in the electrical accessories or internal parts of the pump may only be carried out by authorized Extol® service centers (service locations can be found on the website in the introduction to the manual).
• During pump operation, prevent the flow rate from decreasing due to a reduced discharge hose diameter (e.g., by bending) or damage to the hose by sharp objects.
• During pump operation, ensure that abrasive loose material (e.g., sand), debris, mud, or other unsuitable materials or chemicals do not enter the pumped liquid.
• If the pump is out of operation for a long time or if there is a risk of water freezing, do not leave the pump in the pumped water.

R

Directive 2006/42 EC for all machinery stipulates the obligation to inform the user that the operation of machinery generates electromagnetic radiation, which can negatively affect the functioning of pacemakers and thus endanger the life of a user with a pacemaker.

VI. Pump Storage

• Store the washed and rinsed pump without water in a dry place out of reach of children. The pump must not be stored in places where there is a risk of mechanical or thermal damage to the pump body, float switch, or power supply and float switch cable. Caution! Cable insulation is often damaged by rodents.
