These installation and operating instructions are an integral part of the product. They must be kept readily available at the place where the product is installed. Strict adherence to these instructions is a precondition for the proper use and correct operation of the product. This installation and operating instructions correspond to the relevant version of the product and the underlying safety standards valid at the time of going to print.

EC declaration of conformity:
A copy of the EC declaration of conformity is a component of these operating instructions. If a technical modification is made on the designs named there without our agreement, this declaration loses its validity.

Safety

These operating instructions contain basic information which must be adhered to during installation, operation and maintenance. For this reason, these operating instructions must, without fail, be read by the service technician and the responsible specialist/operator before installation and commissioning. It is not only the general safety instructions listed under the main point “safety” that must be adhered to but also the special safety instructions with danger symbols included under the following main points.

General danger symbol

Danger due to electrical voltage

Personnel qualifications
The installation, operating, and maintenance personnel must have the appropriate qualifications for this work. Area of responsibility, terms of reference, and monitoring of the personnel are to be ensured by the operator. If the personnel are not in possession of the necessary knowledge, they are to be trained and instructed. This can be accomplished if necessary by the manufacturer of the product at the request of the operator.

Electrical connection

WARNING! Risk of electric shock!
Danger from electrical current must be eliminated.

Have all electrical work carried out by a qualified electrician only!
Before any electrical connection is made, the pump must be de-energized (switched off) and protected against unauthorized restarting.
To ensure safe installation and operation, the unit must be earthed correctly with the earth terminals of the power supply.

CAUTION!
An error in the electrical connection will damage the motor. The power cable must never touch the piping or the pump and must be kept away from any moisture.

See the pump cladding for its electrical characteristics (frequency, voltage, current).
The single-phase motor of this pump has a built-in thermal protector.
See the wiring diagram marked on the inside of the terminal cover, fasten the cable with the cable gland and cable anchorage located in the terminal box securely when the cable connector.
The cross-section of the supply cord for this pump shall be at least 3 x 0,75 mm² and the properties of the supply cord shall be at lease ordinary polychloroprene sheathed cords (60245 IEC 57).
A damaged cable or connector must be replaced by the corresponding part available from the manufacturer or the manufacturer’s customer service.

Commissioning
Check that there are no leaks at the connections to the sanitary devices connected to the lifting unit.

Switch the power supply to the unit.
Check that the current consumed is less than or equal to the rated current.

Maintenance

All maintenance work must be carried out by authorised and qualified personnel!

WARNING! Risk of electric shock!
Danger from electrical current must be eliminated.

Before carrying out any electrical work, the pump must be de-energized (switched off) and protected against unauthorised restarting. It is recommended to disconnect the plug.

No special maintenance work is required during operation.
Keep the pump clean.
If the pump is deactivated for a long period and there is no risk of freezing, it is best not to drain the pump. In the event of prolonged absence, be sure to cut off the mains water supply and protect the installation from freezing.
