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 fall below the minimum value Q
min
.
Calculation of Q

7.4 Preparing the installation
Check whether the pump complies with the specifications on the delivery note; report
any damage or missing parts to Wilo immediately. Check slat crates/boxes/wrappings
for spare parts or accessory components which could be included with the pump.
WARNING
Risk of personal injury and property damage due to improper handling!
• Install only after completion of all welding and soldering work and after the
pipeline system has been flushed, if required.
⇒ Dirt can cause the pump to fail.
Installation location
ƒ
The pump must be protected from the weather and installed in a frost-/dust-free,
well ventilated, vibration-isolated environment that is not potentially explosive.
The pump must not be installed outdoors! Observe the specifications in the
chapter "Intended use"!
ƒ
Mount the pump in a readily accessible place. This makes it easier to complete in-
spections, maintenance (e.g. mechanical seal change) or replacement in the future.
Observe the minimum axial distance between the wall and the fan cover of the
motor: free removal dimension of at least 200 mm + diameter of the fan cover.
ƒ
Install a device for attaching hoisting gear above the set-up site of the pumps.
Total weight of the pump: see catalogue or data sheet.
Base
CAUTION
A faulty foundation or incorrect installation of the unit!
A faulty foundation or incorrect installation of the unit on the foundation can lead to
defects of the pump.
• These defects are not covered by the warranty.
• Never set up the pump unit on unfortified surfaces or surfaces that cannot bear
loads.
NOTICE
For a vibration-insulated installation, a simultaneous isolation of the base block it-
self from the building structure by an elastic intermediate layer (e.g. cork or Mafund
pad) is required for few pump types.
WARNING
Personal injury and property damage due to improper handling!
Transport lugs mounted on the motor housing can tear out if the load is too heavy.
This can lead to serious injuries and damage to the product!
• Only lift the pump with approved lifting gear (e.g. block and tackle, crane). See
also chapter “Transport and storage”.
• Transport lugs mounted on the motor housing are only permitted for transporting
the motor!
