Check whether the pump complies with the specifications on the delivery note; report any
damage or missing parts to Wilo immediately. Check slatted crates/boxes/wrapping for
spare parts or accessory components that could be included with the pump.
WARNING
Risk of personal injury and property damage due to improper
handling!
• Never set up the pump unit on unfortified surfaces or surfaces that
cannot bear loads.
• Flush the pipeline system if required.
– Dirt can cause the pump to fail.
• Install only after completion of all welding and soldering work and
after the pipeline system has been flushed, if required.
• Observe the minimum axial distance between a wall and the fan cover
of the motor: 200 mm + diameter of the fan cover.
NOTICE
Simplify subsequent work on the unit!
• To ensure the entire unit does not have to be emptied, install shut-off
valves upstream and downstream of the pump.
NOTICE
The motor terminal box must not face downward.
•
The pump must be protected from the weather and installed in a frost-/dust-free, well
ventilated, oscillation-isolated environment that is not potentially explosive. The pump
must not be installed outdoors! Observe the specifications in "Intended use" section!
•
Mount the pump in a readily accessible place. This makes it easier to complete inspec-
tions, maintenance or replacement in the future.
Lay the suction pipe as short as possible.
•
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.
The pump units can be mounted on their foundations in many different ways. The type of
fixation depends on the size and location of the pump unit as well as noise and vibration
regulations.
NOTICE
For some pump types, simultaneous separation of the foundation block
itself from the building structure by means of an elastic intermediate
layer (e.g. cork or MAFUND® plate) is required for vibration-insulated in-
stallation.
