The electric pumps are packed in cartons or wooden crates having different dimensions and shapes.
Some packages are designed to be transported, handled and stored in the vertical position.
WARNING
Other packages are designed to be transported, handled and stored in the horizontal position.
Protect the product against humidity, dirt, heat sources, vibrations and mechanical damage (collisions,
falls, ...). Do not place heavy weights on the packed products and do not stack them.
Lift and handle the product carefully, using suitable lifting equipment. Observe all the accident prevention
regulations.
The electric pump must never be lifted from the motor cable.
