CAUTION
Damage to the pump due to overheating!
The pump must not be allowed to operate dry for more than 1 minute. Dry running
causes a build-up of energy in the pump, which can damage the shaft, impeller, and
mechanical seal.
• Make sure that the volume flow does not fall below the minimum value Q
min
.
Approximate calculation of Q
min
:
Q
min
= 10 % x Q

6.4 Permitted installation positions
and change of the arrangement of
components before the installa-
tion
Fig. 7: Arrangement of the components upon
delivery
The component arrangement concerning the pump housing is pre-assembled as a fact-
ory setting (see Fig. 7) and can be changed at the operating location if required. This
may be necessary, for example, in the following cases:
ƒ
Ensuring pump venting
ƒ
Enabling better operation
ƒ
Avoid impermissible installation positions (motor and/or electronic module point
downwards).
In most cases, it is enough to rotate the motor impeller unit relative to the pump hous-
ing. The possible arrangement of components is the result of the permitted installation
positions.
6.4.1 Permitted installation positions
with horizontal motor shaft
Fig. 8: Permitted installation positions with ho-
rizontal motor shaft
The permitted installation positions with horizontal motor shaft and electronic module
facing up (0°) are shown in Fig. 8.
Any installation position is allowed except for “electronic module facing down” (-180°).
Venting of the pump is only ensured when the air vent valve is pointing upwards (Fig. 8,
Item 1).
Only in this position (0°) can condensate be directed away via existing drilled holes,
pump lantern and motor (Fig. 8, Item 2).
