Transport and interim storage

When you receive the equipment, check that it has not been damaged during transport. If you notice a fault, take all necessary action with the carrier within the time allowed.

CAUTION! Storage environment may cause damage
If the equipment is to be installed at a later date, store it in a dry place and protect it from impacts and any external stresses (humidity, frost, etc.). Temperature range for transport and storage:

• – 30°C to +60°C

Handle the pump with care so as not to damage the product before installation.

Application

These devices are domestic pressure-boosting systems designed for pressurizing clean water. The downward type is designed for boosting water from the roof- top water tank to lower floors using water and the upward type is designed for boosting water from the tank on the ground to the upper floors.

DANGER! Risk of explosion!
Do not use this pump to convey flammable or explosive liquids.

• 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.
