Translation of original Operating and Installation Instructions
6.2. Electrical connection
Only have the pump connected by an authorised specialist.
Only have the pump connected when the power supply is
disconnected.
When connecting the device to a power source, the relevant
norms, directives, regulations and technical standards must be
observed.
Connecting the pump
Make sure that the power supply data match the data on the
motor's type plate. The operating current can be found on the
type plate.
Connect positive and negative terminals. For electrical data
see Chapter 4
With DC motors, please pay attention to correct polarity:
red motor cable: +
black motor cable: -
6.3. Hydraulic connection
Only connect components to the pump that are designed to
handle the hydraulic data of the pump (see
Chapter 4. Technical data)
Only use hoses that are suitable for the maximum permissible
operating pressure of the pump (see Chapter 4).
Only use hoses that are sufficiently chemically resistant to the
liquids being transferred.
6.3.1. Connecting the pump
Arrows on the pump head indicate the flow direction.
Remove the protective caps.
Connect the suction and pressure lines.
Keep the suction line as short as possible in order to keep the
priming process as brief as possible.
If the pump is used to build up pressure, make sure that all
transition joints between hose and pump are secure in order to
ensure that the hoses cannot come off.
Check that the hoses and transition joints are fitted correctly
and securely.
Check that the system is leak-tight.
