7.5 Priorities during operation of pump, PLR, LON,
IR monitor
The highest priority goes to displaying errors (menu 18) incl. their
acknowledgement. This means that errors take precedence on the
pump's display and that they must be acknowledged and removed.
If settings are made on the E module or from the IR monitor and not
confirmed, the setting will return to the previous position 30 s after
the last entry.

Installation

Installation and commissioning by qualified staff only

8.1 Assembly

Before installing the pump make sure that all welding and solde-

ring has been completed and the pipe system flushed out, if
necessary. Dirt can have an adverse effect on the functioning of
the pump.
Standard pumps must be installed in a frost/dust-free, well-aired
x
and non-explosive environment, suitably protected against
weather conditions.
The pump must be installed in a readily accessible place to facili-
x
tate inspection and maintenance (e.g. mechanical seal) or repla-
cement. The flow of air to the heat sink of the electronic module
must not be restricted.
A hook or an eye with appropriate load-bearing capability (total
x
weight of pump: see catalogue / data sheet) must be fitted
directly above the pump, to which lifting gear or similar equip-
ment may be attached when maintaining or repairing the pump.
Lifting eyes on the motor must only be used to sup-

port the motor and not the entire pump.
The pump must be lifted using authorised load suspension
x
equipment (see chapter 3).
Minimum axial distance between a wall and the motor fan cowl:
x
free space of min. 200 mm + l of fan cowl.
Shut-off devices should, as a rule, be mounted on the front and
x
back of the pump so as to avoid having to drain the entire unit
when inspecting or changing the pump.
There should be no mechanical strain between the pipeline and
x
the pump. The pipeline must be fixed so that the pump is not
supporting the weight of the pipes.
The vent valve (Fig. 9, 10, pos. 8.2) must always point upwards.
x
Any installation position is permitted except for "motor down-
x
wards". No motor support is required (see Fig. 7, 8).
The electronic module must not point downwards. If necessary, the
motor can be rotated after loosening the hexagon bolts.

ensure that the pressure gauge lines are not bent or

The flow direction must correspond to the directional arrow on

always a sufficiently high liquid level above the suc-
tion part to avoid dry-running of the pump. The

minimum inlet pressure must be observed.
If the pump is used in air-conditioning or refrigeration units, the
x
condensate in the lantern can be drained off selectively via exi-
sting bore holes.
In insulated units, only the pump housing (Fig. 9, 10,
CAUTION!
pos. 3) may be insulated, not the lantern and the
motor.

8.2 Electrical connections

Electrical connection must be carried out by an electri-
cal installer authorised by the local power supply com-
pany in accordance with the applicable local regulations
(e.g. VDE regulations). The motor may only be operated
in combination with a frequency converter. The fre-
quency converter may only be used in combination with
this motor.
According to Part 105 of VDE 0160, the electrical connection
x
must be made by a solid wire (min. 4 x 1.5 mm
equipped with a plug or an all-pole switch. The width of the con-
tact gap must be at least 3 mm. The cable must be fed through
cable gland M 25.
To guarantee protection against dripping water and for strain
x
relief of the gland, cables with an adequate outer diameter shall
be used. The cables should be screwed sufficiently tight. In addi-
tion, cables positioned near the gland must be formed into a sort
of discharge hose in order to carry drops of water away from the
gland. Glands which are not used must be closed using the plugs
provided by the manufacturer.
The supply cable must be laid in such a way that it never touches
x
the pipework and/or the pump and motor casing.
This pump is equipped with a frequency converter and must not
x
be protected with an FI safety switch. Frequency converters can
affect the function of FI safety switches.
Exception: Selective, all-current sensitive FI safety switches may
be used.
