➔ Generally speaking, the pump can be mounted in any orienta-
tion. For maximum precision and rapid venting, install pump as
shown in the illustration (Fig. 4).
Decoupling

➔ KNF recommends mechanically decoupling the pump from the
piping system. This can be achieved with flexible hoses or
pipes, for example. This prevents any oscillations of the pump
being transferred to the system.
