INSTALLATION

6.4. Installation
DANGER: heights!
When installing the pump and its accessories, work
is sometimes performed directly at the edge of the
well or tank. Carelessness and/or wearing inappro-
priate clothing may result in a fall. There is a risk of
fatal injury! Take all safety precautions to prevent
a fall.
Observe during pump installation:
• This work must be carried out by qualified personnel and electrical work must be carried
out by an electrician.
• The operating space must be clean, free of coarse solids, dry, frost-free and, if neces-
sary, decontaminated. It must also be suitable for the particular pump. There must be
sufficient water inflow for the submersible pump's maximum output in order to prevent
dry run and/or air intake.
• When working in tanks, wells or boreholes, a second person must be present for safety
reasons. If there is a risk of toxic or asphyxiating gases building up, the necessary pre-
cautions must be taken.
• Ensure that lifting equipment can be set up without any trouble, since this is required
for installing and dismantling the pump. It must be possible to reach the pump safely in
its operating and storage locations using the lifting equipment. The set-down location
must have a solid bearing surface. The lifting gear must be attached to the defined
lifting eyes to transport the pump. When using chains, these must be connected to the
lifting eyes using a shackle. Lifting gear must be technically approved.
• Connection cables must be routed in such a way that safe operation and easy installati-
on/dismantling are possible at all times. Do not carry or pull the pump by the connection
cable.
The pump is delivered ex works with a connected connection cable for the power
supply. The connection cable must be extended to the required length on site prior to
installation to suit the available space in the borehole using the enclosed sealing kit
(see Section 6.5.1).
Check the cable cross-section used and the routing type chosen. Make sure the availab-
le cable length is sufficient.
• Observe the corresponding protection class when using switchgear. As a rule, install
switchgear overflow-proof.
• Structural components and foundations must be of sufficient stability in order to allow
the product to be fixed securely and functionally. The end user or the supplier is respon-
sible for the provision of the foundations and their suitability in terms of dimensions,
stability, and strength.
