pic 4 - Alignment of coupling with gauge and ruler
pic 5 - Adjustment using dial gauge
Control alignment of coupling again in operation
warm condition and on system pressure (if
available) and correct, if necessary. Pay
attention to chapter 6 beforehand! It must be
possible to turn the unit easily and harmoniously
by hand.
Improper alignment of the unit can lead to
damages at coupling and unit!
Mount coupling guard after alignment and
before start-up.

5.3.4 Coupling Guard
Acc. to accident prevention regulations the
pump must only be operated with coupling
guard.
Care has to be taken, that the used coupling
guard consists of non-sparking material.
