ENGLISH
any water that escapes cannot drip
onto the pump motor or terminal
box.
– When installed into the flow pipe of
an open-vented system, the open
safety vent must be connected to
the system on the inlet side of the
pump.
– Pump to be mounted with the shaft
in the horizontal plane in such a
way that it is not stressed by the
pipework. (Installation positions in
Fig. 2).
– An arrow on the pump casing indi-
cates the direction of flow (fig. 3,
pos.1).
– Secure the pump against twisting
by using a spanner (fig. 4).
– In order to attain the correct termi-
nal box position the motor housing
can be turned once the motor
fastening screws have been lose-
ned (Fig. 5).

be insulated, only the
pump housing may be
insulated. The motor
and condensate ope-
nings must remain free
(fig. 3, pos. 2).
Electrical connection
Electrical connection must
be carried out by a quali-
fied and licensed electrici-
an in strict conformity to
ruling national conditions
18
and local regulations (e.g.
VDE regulations in Ger-
many).
– According to Part 1 of the VDE
0730, the pump must be connec-
ted to the electrical supply by a
solid wire equipped with a plug
connection or an all-pole switch.
The width of the contact gap
must be at least 3 mm.
– To guarantee protection against
dripping water and the strain
relief of the PG screwed joint, a
connecting cable of suitable
external diameter is to be used
(e.g. H 05 VV-F 3 G 1.5).
– When using the pump in units
where the water temperature
exceeds 90 °C, a connecting
cable with corresponding heat
resistance must be used.
– The supply cable must be laid in
such a way that it never touches
the pipework and/or the pump
and motor casing.
– Check that the mains current
and voltage comply with the data
on the rating plate.
– Make mains
shown in Fig. 6.
– The connecting cable can be fed
through the PG screwed joint eit-
her to the left or right. If neces-
sary, the blind plug and PG scr-
ewed joint are to be exchanged.
If the terminal box is positioned
on the side, always insert the PG
screwed joint from below (Fig. 5)
