Make sure that the installation location is dry and the pump is
protected against water in the form of rain, spray, splashes and
drips.
Protect the pump against dust.
Protect the pump against vibration and impact.
The pump can be mounted in any orientation.
Generally speaking, the pump can be mounted in any
orientation. For maximum precision and rapid venting, install
pump as shown in the illustration (Fig. 6).
KNF recommends mechanically decoupling the pump from the
pipework system, e.g. by using flexible hoses or pipes. This
prevents any oscillations of the pump being transferred to the
system.
6.2. Electrical connection
For pumps with direct current motors:
Pump should only be connected by an authorised specialist.
Only connect the pump when the power supply is turned off.
All electrical connection work must adhere to the pertinent
norms, directives, regulations and technical standards.
Connecting the pump
1. Make sure that the power supply data match the data on the
motor type plate. The current consumption can be found on the
type plate.
2. Connect the motor cables. For electrical data see Chapter 4.
Always check polarity of cables.
For DC motors:
red motor lead: +
black motor lead: -
In the case of brushless DC motors:
incorrect polarity may damage the electronics.
