Installation and operating instructions LRE, JRE
• Depending on the pump type, rotate the motor impeller unit by 45°,
90° or 180° (or 90° or 180°) in the desired direction. Then reinstall the
pump in reverse order.
• Fasten the holder of the differential pressure sensor (Fig. 6, Item 6)
with one of the screws (Fig. 6, Item 1.4) on the side opposite the elec-
tronic module (the position of the differential pressure sensor relative
to the electronic module does not change when doing this).
• Wet the O-ring (Fig. 6, Item 1.13) well before installation (do not
install the O-ring in a dry condition).
NOTE:
Be sure that the O-ring (Fig. 6, Item 1.13) is not installed in a twisted
position or squeezed during installation.
• Before commissioning, fill the pump/system and apply system pres-
sure; check for leaks afterwards. If there is a leak at the O-ring, first air
will come out of the pump. This leakage can, for example, be checked
with a leakage spray at the gap between the pump housing and the
lantern as well as their screwed connections.
• In the event of continual leakage, use a new O-ring, if need be.
CAUTION! Risk of property damage!
Incorrect handling can result in property damage.
• When turning the components, make sure that the pressure meas-
uring lines are not bent or kinked.
• When reinstalling the differential pressure sensor, bend the pressure
measuring lines evenly and as little as possible to put them into the
required position or into a suitable position. When doing this, do not
deform the areas at the clamp boltings.
• For optimal positioning of the pressure measuring lines, the differen-
tial pressure sensor can be separated from the holder (Fig. 6, Item 6),
rotated by 180° around the longitudinal axis and reinstalled.
NOTE:
When turning the differential pressure sensor, make sure not to mix
up the pressure and suction sides on the differential pressure sensor.
For additional information about the differential pressure sensor, see
chapter 7.3 "Electrical connection" on page 77.
• The pump should only be installed after completion of all welding and
soldering work and, if necessary, flushing of the pipe system. Dirt can
cause the pump to fail.
• The pumps must be protected from the weather and installed in a
frost/dust-free, well-ventilated environment which is not potentially
explosive. The pump must not be installed outdoors.
• Install the pump in a place that is easy to access so that subsequent
inspections, maintenance (e.g. mechanical seal) or replacement is
easily possible. The air access to the heat sink of the electronic mod-
ule must not be restricted.
• A hook or eyelet with the corresponding bearing capacity is to be
installed vertically above the pump (for the total weight of the pump:
see catalogue/data sheet), to which hoisting gear or similar aids can be
attached when conducting maintenance or repair work on the pump.
