7.5 Priorities during operation of pump, PLR, LON

The highest priority goes to displaying errors (menu 18) incl.
their acknowledgement. This means that errors take prece-
dence on the pump's display and that they must be ack-
nowledged and removed.
If settings are made on the E module and not confirmed, the
setting will return to the previous position 30 s after the last
entry.

8 INSTALLATION

Installation and commissioning by qualified staff only

8.1 Assembly

Before installing the pump make sure that all welding and sol-
x
dering has been completed and the pipe system flushed out,
if necessary. Dirt can have an adverse effect on the functio-
ning of the pump.
Standard pumps must be installed in a frost/dust-free, well-
x
aired and non-explosive environment, suitably protected
against weather conditions.
The pump must be installed in a readily accessible place to
x
facilitate inspection and maintenance (e.g. mechanical
seal) or replacement. 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
x
(total weight of pump: see catalogue / data sheet) must be
fitted directly above the pump, to which lifting gear or similar
equipment may be attached when maintaining or repairing
the pump.
Lifting eyes on the motor must only be used to

support 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
x
cowl: free space of min. 200 mm + l of fan cowl.
Shut-off devices should, as a rule, be mounted on the front
x
and back of the pump so as to avoid having to drain the enti-
re unit when inspecting or changing the pump.
There should be no mechanical strain between the pipeline
x
and 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
x
downwards". No motor support is required (see FIG. 7, 8).
The electronic module must not point downwards. If necessa-
ry, the motor can be rotated after loosening the hexagon
bolts.
After loosening the hexagon bolts the differenti-

al pressure only remains fastened to the pressure
gauge lines. When rotating the motor housing
ensure that the pressure gauge lines are not
bent or buckled.
The flow direction must correspond to the directional arrow
x
on the pump housing flange.
CAUTION!
If the pump is used in air-conditioning or refrigeration units,
x
the condensate in the lantern can be drained off selectively
via existing bore holes.
CAUTION!

8.2 Electrical connections

dis-
According to Part 105 of VDE 0160, the electrical connection

X
must be made by a solid wire (min. 4 x 1.5 mm
.

mm
the contact 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 addition, 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 tou-
x
ches the pipework and/or the pump and motor casing.
This pump is equipped with a frequency converter and must
x
not be protected with an FI safety switch. Frequency conver-
ters can affect the function of FI safety switches.

When sucking from a tank ensure that there is
always a sufficiently high liquid level above the
suction part to avoid dry-running of the pump.
The minimum inlet pressure must be observed.
In insulated units, only the pump housing (FIG. 9,
10, pos. 3) may be insulated, not the lantern and
the motor.
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 regula-
tions (e.g. VDE regulations).
The motor may only be operated in combination with a
frequency converter. The frequency converter may
only be used in combination with this motor.
