Connecting the pump
Compare the data of the supply voltage and the maximum
permissible current with the information on the motor type
plate.
Connect the motor cable. Electrical data section 4.
Attention: observe the polarity of the leads!
For DC motors:
Red motor lead: +
Black motor lead: -
In the case of a Brushless motor false polarity can cause
damage to the electronics.
For an alternating current motor the power supply may only
vary by a maximum of +/- 10 % of the specifications on the
type plate.
6.3. Hydraulic connection
Only connect components to the pump which are designed for
the pneumatic data of the pump (see Chapter 4, Technical da-
ta).
Only use tubing which is suitable for the maximum pressure of
the pump. (see section 4.)
Only use tubing which is resistant to the liquids being pumped.
6.3.1. Connecting tubing to the pump
Arrows on the pump head indicate the flow direction.
1. Remove the protective caps from the connections.
2. Connecting the inlet and outlet tubing.
Keep the inlet tube so short as possible in order to keep the
priming process as short as possible..
3. If the pump is used to build up pressure it is important to en-
sure that all hydraulic connections on the outlet side are se-
cure to prevent leakage.
4. Check tubes and hose barbs for leak tightness.
5. Check that the system is leak tight.
