CAUTION! Damage to the pump due to overheating!
The pump must not be allowed to operate dry for more than
1 minute. Dry running causes a build-up of energy in the pump,
which can damage the shaft, impeller, and mechanical seal.
• Make sure that the volume flow does not go below the minimum
value Q .

Calculation of Q :

Q = 10% x Q x

• The pump has to be checked for compliance with the specifications
on the delivery receipt; Wilo has to be informed of any damage or
missing parts. Check slat crates/cartons/wrappings for spare parts or
accessory components which could be included with the pump.
• The pumps must be protected from the weather and installed in
a frost/dust-free, well-ventilated and vibration-insulated environ-
ment 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 suction line is to be kept as short as possible.
• For a vibration-insulated installation, a simultaneous isolation of the
base block itself from the building structure by an elastic intermediate
layer (e.g. cork or Mafund pad) is required.
CAUTION! Risk of damage to property!
Danger of damage due to incorrect handling.
• A missing foundation or an incorrect installation of the unit on the
foundation can lead to a malfunction of the pump; this is not cov-
ered by the warranty.
• Anchor bolts (M20) for the base plate drilled holes are necessary for
anchoring.
• The concrete foundation has to be hardened before the unit is put on.
Its surface has to be horizontal.
• 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 pump failure.
