the unit. As a result of cavitation, the product does not
run smoothly and is subjected to increased wear.
5.4 Installation
Danger of falling!
When installing the product and its accessories,
work is sometimes performed directly at the
edge of the basin or shaft. Carelessness and/or
wearing inappropriate clothing could result in a
fall. There is a risk of fatal injury! Take all neces-
sary safety precautions to prevent this.
The following information must be observed when
installing the product:
• This work must be carried out by a qualified person and
electrical work must be carried out by an electrician.
• Lift the unit by the handle or lifting eyelets, never by
the power supply cable. When using chains, they must
be connected with a shackle to the lifting eyelets or
the carrying handle. Fastening devices must be techni-
cally approved.
• Check that the available planning documentation
(installation plans, layout of the operating area, intake
ratios) is complete and correct.
If the motor housing is to be taken out of the
pumped liquid during operation, the operating
mode for emerged operation should be followed.
If this operating mode is not specified, operation
with an emerged motor housing is strictly forbid-
den.
Never let the machine run dry. We recommend
that dry-run protection be installed. If fluid levels
deviate dramatically, a dry-run protection must
be installed.
Check whether the cross section of the cable
used is sufficient for the required cable length
(see the catalog and planning documents or con-
sult Wilo customer service for more information).
• Please observe all regulations, rules and legal require-
ments for working with and underneath heavy sus-
pended loads.
• Wear appropriate protective clothing/equipment.
• A second person must always be present when work-
ing in shafts. If there is danger of poisonous or asphyxi-
ating gases forming, the necessary countermeasures
must be taken!
• Please also observe the applicable national accident
prevention regulations and trade association safety
provisions.
• The coating is to be examined before installation. If
defects are found, these must be rectified before
installation.

A suspension unit must be installed for wet installation.
This must be ordered separately from the manufac-
turer. The pipeline system on the discharge side is con-
nected to this. The connected pipe system must be
self-supporting, i.e. it may not be supported by the
suspension unit. The operating area must be laid out so
that the suspension unit can be installed and operated
without difficulty.
1 Install suspension unit in operating area and prepare the
product for operation on a suspension unit.
2 Check that the suspension unit is firmly fixed and
functions properly.
3 Have an electrician connect the product to the power
supply and check the direction of rotation in accor-
dance with the chapter entitled "Start-up".
4 Secure the product to the load-carrying equipment, lift
and lower slowly on to the guide pipes in the operating
area. Hold the electric power cables slightly taut when
lowering. When the product is connected to the sus-
pension unit, make sure that the electric power cables
are secured adequately against falling off and damage.
5 The correct operating position is reached automatically
and the discharge port is sealed by its own weight.
6 For new installation: Flood the operating area and bleed
the discharge pipe.
7 Start the product in accordance with the chapter enti-
tled "Start-up".

coupling
4 Storz fixed coupling
With this installation type, the product must be
equipped with a pedestal (available as an optional
extra). It is fitted to the intake port and ensures the
minimum floor clearance and a secure position on a
firm foundation. This installation type makes optional
positioning in the operating area possible. For use on a
soft foundation, a hard base must be used to prevent
the machine from subsiding. A discharge hose is con-
nected on the discharge side.
The unit must be anchored to the floor for longer oper-
ating times with this type of installation. This prevents
vibrations as well as guaranteeing quiet and low-wear-
ing running.
1 Mount the pedestal at the intake port.
2 Attach the pipe bend to the discharge port.
3 Fix the discharge hose to the pipe bend with the hose
clamp.
