INSTALLATION
the hydraulics from damage during transporta

tion. If you have any questions, please contact
Wilo customer service!
5. Installation
In order to prevent damage to the product or seri-
ous injury during installation, the following points
must be observed:
•
Installation work – assembly and installation
of the hydraulics – may only be carried out by
qualified persons. The safety instructions must be
followed at all times.
•
The hydraulics must be inspected for transport
damage before any installation work is carried
out.
5.1. General
For design and operation of technical sewage
systems, observe the pertinent local regulations
and directives for sewage technology (such as
those of sewage technology associations).
Note that, in stationary installations, pressure
surges can occur in cases where water is pumped
with longer discharge pipes (especially with
steady ascents or steep terrain).
Pressure surges can result in destruction of the
hydraulics/system and noise pollution due to flap
knock. Pressure surges can be prevented by ap
-
plying suitable measures (e.g. non-return valves
with an adjustable closing time or special routing
of the discharge pipeline).
Air pockets in the hydraulics or piping system
must be avoided at all costs and must be removed
using a suitable ventilation system.
Protect the hydraulics from frost.
5.2. Installation types
•
Horizontal stationary dry well installation
5.3. Installation
NOTE
Also note all the information regarding installa
-
tion in the operating and maintenance manual
for the motor!
The following information should be taken into
consideration when installing the hydraulics:
•
This work must be carried out by a qualified
person and electrical work must be carried out by
an electrician.
•
The operating space must be clean, dry and free
from frost, and designed for the hydraulics in
question.
•
When working in pump chambers, a second per
-
son must be present for safety reasons. If there is
a risk of poisonous or asphyxiating gases forming,
the necessary precautions must be taken.
•
Ensure that lifting equipment can be fitted with
-
out any trouble, since this is required for assembly
and removal of the hydraulics. It must be possible
to reach the hydraulics safely in their operating
and storage locations using the lifting equip
-
ment. The machine must be positioned on a firm
bearing surface. For transporting the hydraulics,
the load-carrying equipment must be secured to
the prescribed attachment points. When using
chains, these must be connected to the attach-
ment point using a shackle. Lifting gear must be
technically approved.
• Structural components and foundations must be
of sufficient stability in order to allow the product
to be fixed 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!
•
Never let the hydraulics run dry. Air pockets are
to be avoided at all costs. Appropriate ventilation
systems must be provided.
•
Check the available consulting documentation
(installation plans, design of operating space,
inlet conditions) is complete and correct.
• Please observe all regulations, rules and legal
requirements for working with and underneath
heavy suspended loads. Wear appropriate protec
-
tive clothing/equipment.
• Please also observe the applicable national acci-
dent prevention regulations and trade association
safety provisions.
5.3.1. Attachment points
To raise and lower the hydraulics, they must be
fastened at the specified attachment points. We
differentiate here between the unit and the "bare
shaft" version.
