• Rotate the motor impeller unit by 90° or 180° in the desired direction
• Fasten the differential pressure sensor holder with one of the screws
• Thoroughly wet the O-ring (Fig. 6, Item 1.14) before installation
The permitted installation positions with horizontal motor shaft and
electronic module facing up (0°) are shown in Fig. 18. The permissible
installation positions with electronic module mounted on the side
(+/-90°) are not shown. Any installation position is allowed except for
"electronic module facing down" (-180°). The venting of the pump
is only ensured when the air vent valve is pointing upwards (Fig. 18,
Item 1). Only in this position (0°) can condensate be directed away
via existing drilled holes, pump lantern and motor (Fig. 18, Item 2).
Remove the plug from the motor flange.
The permitted installation positions with vertical motor shaft are
shown in Fig. 19. All installation positions except for "motor facing
down" are allowed.
The motor impeller unit can be arranged in 4 different positions, rela-
tive to the pump housing (each shifted by 90°).
NOTICE:
To make the installation work easier, it can be helpful to install the
pump in the piping without electrical connection and without filling
of the pump or system (see chapter 10.2.1 "Replacing the mechanical
seal" on page 117 for installation steps).
and install the pump in the reverse order.
on the side opposite the electronic module (the position of the differ-
ential pressure sensor relative to the electronic module does not
change when doing this).
(do not install the O-ring in a dry state).
NOTICE:
Be sure that the O-ring (Fig. 6, Item 1.14) is not installed in a twisted
position or pinched during installation.
