Installation
1.
Prepare the installation site so that the pump can be installed
without being exposed to mechanical stresses.
2.
Choose the right installation position - only as illustrated in
(Fig. A).
The arrow on the back of the housing indicates the direction
of flow.
Turn the motor head or
remove it.
3.
Undo the cap nut - unscrew it completely if necessary.
4.
Turn the motor head so that the cable screw connection
points downwards.
5.
Tighten the cap nut again.
Open the stop valve
6.
Turn the slot (1) with a screwdriver so that it is parallel to the
direction of flow.
7.
Fit the thermal insulation shell.
Connect
8.
Connect the pipework.
Note:
The stop valve and non-return valve are already
installed. No other stop valves are necessary.

Caution:
Do not damage the housing and seal. Replace
damaged seal.
Caution:
If the cable screw connection is in the wrong
position, water can penetrate into the pump and destroy the
motor or the electronics.

Note:
To close the slot, position it so that it lies across the
direction of flow.
Caution:
In the case of the versions with check valve and
non-return valve, these are already pre-assembled with a tight-
ening torque of 15 Nm (hand-tight). If the tightening torque is
too high, this will destroy the valve screw connection and the
O-ring.
When installing the valve, use a wrench to prevent it from turn-
ing!
