If the pump head is removed before the pump is installed in the
pipework, pay special attention when fitting the pump head to the
pump housing:
1. Gently lower the pump head with rotor shaft and impeller into
the pump housing.
2. Make sure that the contact face of the pump housing and that
of the pump head are in contact before the clamp is tightened.
