Operating and Installation Instructions
9
In order to ensure that emissions comply with the EN 55014-1
emission standard, this pump type with a brushless DC motor DCB
must be fitted with an additional circuit. The additional circuit must
be installed as closely as possible to the motor.
The additional circuit must be installed according to the following
wiring diagram and its defined components in order to achieve the
required level of attenuation.
Fig. 8: Additional circuit
5.3. Pneumatic connection
Only connect components to the pump that are designed to
handle the pneumatic data of the pump (see Chapter 4, Tech-
nical data)
Only use hoses that are suitable for the maximum operating
pressure of the pump (see Chapter 4)
Only use hoses that are chemically resistant to the media be-
ing pumped
5.3.1. Connecting the pump
Arrows on the pump head indicate the flow direction.
Remove the protective caps from the hose
connections.
Connect the suction and pressure lines.
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 (hose connect-
or/hose) are fitted correctly and securely.
Check that the system is leak-tight.
