same time, installation should be
carried out such that any leaking
water cannot drop onto the control
module, align upper slide valve
laterally.
– Carry out off-load installation
with the pump motor lying hori-
zontally. Mounting positions for
the module see fig. 3. Other
mounting positions on request.
– An arrow on the pump casing
indicates the direction of flow
(fig. 4, Pos.1).
– When screwing the pump into the
pipework the pump can be secu-
red with a spanner against turning
at the appropriate points (fig. 5).
– If the mounting position of the
module is to be changed, the
motor casing must be rotated as
follows:
– Unscrew 2 Allen screws on
pump casing,
– Rotate motor casing, including
control module,
Be careful
