device damage hazard
electrocution hazard
NOTE: read the manual prior to commencement of use. For safety
reasons, the pump can only be operated by persons well-familiarised.
NOTE: the manual is a primary part of the purchase and sale contract. The user’s
failure to observe the instructions included in the manual is a breach of the
contract and excludes any complaints arising from potential device failure
caused by the use that is inconsistent with instructions of its use.
NOTE: failure to observe the instructions included in the manual can
result in hazard for persons, properties in which they are installed,
environment and the pump itself.
CAUTION! This equipment is not intended for use by persons (including children) with
reduced motor, sensory or mental capacities, or persons without experience or not
familiarised with the equipment, unless it is performed under supervision
or according to the instruction regarding operation provided by persons responsible for their safety.
Attention should be paid so that children do not play with the equipment.
APPLICATION:
The pumps referred to in the manual are intended for pumping clean water from bored deep
water intakes or increasing pressure in water systems with the enclosure of the aggregate in a
hermetic jacket.
They can be used in households as water supply, means of irrigation, in heat pump
installations, and to feed water into industrial installations. The pumped water cannot contain
any mechanical contamination.
1
The pump is intended for pumping of clean water, with no solid- abrasive particles.
Pumping water containing sand results in fast wear and tear of the pump and, in
consequence, it its failure. In such a case, only paid repair is available. The above not
refers to the pumps with increased resistance to sand.

Summary

Pump Application and Water Quality

Intended Use and Contaminant Limits

Describes use for clean water and limitations on contaminants like sand and abrasive particles.

Pump Installation Procedures

Assembly of Two-Part Pumps

Instructions for connecting hydraulic and motor parts, tightening screws, and shaft coupling.

Borehole Diameter and Cooling

Specifies maximum borehole diameters for motor cooling and pump efficiency.

Pump Installation Depth and Dry Operation

Ensuring sufficient water level above discharge port to prevent dry running damage.

Cable Securing and Pump Suspension

Guidance on fixing supply cable and suspending pump to prevent sinking.

Electric Connection and Safety

Switching Frequency and Load

Rule for switching frequency of pump motor (max 30 times/hour) to prevent overload.

Earthing and Power Supply Safety

Mandatory active earthing and liability for lack of it.

Overcurrent and Residual Current Protection

Requirement for overcurrent circuit breaker and RCD not exceeding 30 mA.

Cable Integrity and Voltage Drop

Prohibition of use with damaged cables; checking voltage and selecting cable length.

Cable Extension and Connection

Guidelines for extending cables, hermetic connection, and potential risks.

Generator Matching and Operation

Generator Power Rating

Generator power should be 3-5 times higher than the motor's rated current.

Pump Connection Sequence

Correct sequence for connecting/disconnecting pump and generator to avoid motor burnout.

Storage and Disposal

Storage Conditions

Instructions for storing the pump in a dry room on an even surface.

Device Disposal Requirements

Disposal via selective waste systems and customer entitlement to return used equipment.

Troubleshooting Pump Operation

Pump Does Not Operate

Possible causes: dry operation, overcurrent, or no power supply.

Pump Operates But No Water

Causes: blocked suction, incorrect rotation, high resistance, low voltage, or low water level.

Frequent Switching On/Off

Causes: small hydrophoric tank, lack of air cushion, or narrow pressure switch differential.
