Installation and operating instructions Wilo-RexaLift FIT L 37
INSTALLATION English
• The operating space must be clean, dry, well lit
and free from frost, and furthermore equipped for
the particular lifting unit.
• The operating space must be easily accessible.
Make sure that there are adequate access oppor-
tunities for the transport equipment including
lifting unit, and that any elevators required are
sufficiently large and have an adequate bearing
capacity.
• Adequate ventilation of the operating space must
be assured.
• The lifting unit must be easily accessible for oper -
ation and maintenance. A space of at least 60 cm
must be left clear around the unit (WxHxD).
• The installation surface must be solid (suitable for
accommodating dowels), horizontal and flat.
• The placement of any existing or still-to-be
installed piping (for inlet, pressure and venting) is
to be checked with regard to connection options
to the unit.
• A pump sump must be arranged within the op-
erating space for draining it. This must have the
minimum dimensions of 500x500x500 mm. The
pump used must be selected according to the
delivery head of the lifting unit. In an emergen-
cy, it must be possible to drain the pump sump
manually.
• The power supply cables must be designed to
allow safe operation and installation/dismantling
without difficulty at all times. Never carry or pull
the lifting unit by the power supply cable. Check
whether the cable present is long enough for its
cross-section and its installation type.
• The mounted switchgear/plug are not over -
flow-proof. Ensure suitable installation.
• Structural components and foundations must
be sufficiently stable to allow the product to be
anchored securely and functionally. The operator
or the supplier is responsible for the provision of
the foundations and their suitability in terms of
dimensions, stability and strength.
• Check the available planning documentation (in -
stallation plans, design of operating space, inlet
conditions) is complete and correct.
• Please also observe the applicable national acci-
dent prevention regulations and trade association
safety provisions.
• Additionally comply with the following points if
the lifting unit is installed in a sump:
DANGER of falling!
The work involved in installing the lifting
unit and its accessories may require adopting
a position directly at the edge of the sump.
Lack of care and/or incorrect choice of cloth-
ing can result in falling. There is a risk of fatal
injury! Take all necessary safety precautions
to prevent this.
• Rough solid material must be removed.
•
The sump must be decontaminated if neces -
sary.
• For safety reasons, make sure a second person
is present at all times.
• Take the necessary countermeasures if there
is a risk of poisonous or suffocating gases
collecting!
• Depending on the ambient conditions in opera-
tion, the unit planner must select the sump size
and motor cooling time accordingly.
• Note the diagonal dimension of the lifting unit.
• It is necessary to guarantee that lifting equip-
ment can be installed without difficulty, since
this will be required for installing/dismantling
the lifting unit. The lifting equipment must
be able to reach the place where the lifting
unit is used and placed without danger. The
location must have a firm bearing surface. Two
transport straps must be used as load-bearing
equipment for transporting the lifting unit.
These must be attached to the reservoir. Only
structurally approved lifting devices may be
used. Also comply with all regulations, rules
and laws on working with heavy and suspended
loads. Wear the necessary physical protection
equipment.
5.3.1. Basic advice on fixing the lifting unit
Lifting units must be installed so they are pre -
vented from twisting and also in an anti-buoyant
fashion depending on the installation location.
For this purpose, the lifting unit must be anchored
to the floor of the operating space. The lifting
unit can be installed on various constructions
(concrete, plastic, etc.). For this reason, the fixa -
tion materials provided by the customer must be
suitable for the relevant construction.
Observe the following instructions for the fixation
material:
• Ensure the proper edge clearance in order to
prevent the construction material from tearing or
chipping.
• The size of the borehole depends on the size of
the bolts. The borehole should be 5 mm deeper
than the bolt length.
• Drilling dust impairs holding strength. Therefore
always blow or vacuum out the borehole.
• Make sure the fixation material is not damaged
during assembly.
5.3.2. Stationary dry well installation in buildings and
sumps
Work steps
The lifting unit is installed in the following steps:
• Positioning the lifting unit and anchoring it to the
floor
• Connecting the pressure pipe
• Connect main inlet DN 100/DN 150
• Connect the bleed line
• Connect inlet DN 50
• Connect the emergency drain
