DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connections can be
life-threatening.
• Electrical connections should only be established by qualified elec-
tricians and in compliance with the applicable regulations!
• Adhere to accident prevention regulations!
DANGER! Risk of fatal injury!
Failure to install safety devices on the terminal box or near the
coupling can cause electrical shock or contact with rotating parts,
potentially resulting in life-threatening injuries.
• Before commissioning, all safety devices (such as terminal box
covers or coupling covers) that were removed must be reinstalled.
DANGER! Risk of fatal injury!
The pump itself and pump parts can be extremely heavy. Falling
parts pose a risk of cuts, crush injuries, bruises or impacts, which
may lead to death.
• Always use suitable lifting equipment and secure parts against
falling.
• Never stand underneath a suspended load.
• Make sure the pump is securely positioned and is stable during
storage and transport as well as prior to all installation and other
assembly work.
CAUTION! Risk of property damage!
Risk of damage due to incorrect handling.
• Have the pump installed by qualified personnel only.
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 Qmin does not fall below the
minimum value.
Calculation of Qmin:
Q = 10 % x Q
min max pump
• The pump must be checked for compliance with the specifications on
the delivery receipt; any damages or missing parts must be conveyed
to Wilo immediately. Check slat crates/boxes/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 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 later inspec-
tions, maintenance (e.g. the mechanical seal) or replacement is easily
possible.
• Provide space for minimum axial distance between a wall and the fan
cover of the motor: Free removal dimension of at least 200 mm +
diameter of the fan cover.
