Installation and operating instructions
1 General
About this document
These installation and operating instructions are
an integral part of the product. They must be kept
readily available at the place where the product is
installed. Strict adherence to these instructions is
a precondition for the proper use and correct
operation of the product.
These installation and operating instructions correspond to the relevant version of the product and
the underlying safety standards valid at the time
of going to print.
2Safety
These operating instructions contain basic information which must be adhered to during installation and operation. For this reason, these
operating instructions must, without fail, be read
by the service technician and the responsible
operator before installation and commissioning.
It is not only the general safety instructions listed
under the main point "safety" that must be
adhered to but also the special safety instructions
with danger symbols included under the following
main points.
2.3 Danger in the event of non-observance of the
safety instructions
Non-observance of the safety instructions can
result in risk of injury to persons and damage to
pump/installation. Non-observance of the safety
instructions can result in the loss of any claims to
damages.
In detail, non-observance can, for example, result
in the following risks :
• Failure of important pump/installation functions,
• Failure of required maintenance and repair procedures
• Danger to persons from electrical, mechanical and
bacteriological influences,
• Property damage
2.4 Safety instructions for the operator
The existing directives for accident prevention
must be adhered to.
Danger from electrical current must be eliminated.
Local directives or general directives [e.g. IEC, VDE
etc.] and local power supply companies must be
adhered to.
Risks through mechanical or bacteriological
effects must be prevented. Local conditions and
guidelines relating to sewage technology must be
adhered to.
2.1 Indication of instructions in the operating
instructions
Symbols:
General danger symbol
Danger due to electrical voltage
NOTE
Signal words:
DANGER!
Acutely dangerous situation
Non-observance results in death or the most
serious of injuries.
WARNING!
The user can suffer (serious) injuries. 'Warning'
implies that (serious) injury to persons is probable if this information is disregarded.
CAUTION!
There is a risk of damaging the pump/installation. 'Caution' implies that damage to the product is likely if the information is disregarded.
NOTE: Useful information on using the product. It
draws attention to possible problems.
2.2 Personnel qualifications
The installation personnel must have the appropriate qualifications for this work.
2.5 Safety instructions for inspection and
installation work
The operator must ensure that all inspection and
installation work is carried out by authorised and
qualified personnel, who are sufficiently informed
from their own detailed study of the operating
instructions.
Work to the pump/installation must only be carried out when at a standstill.
2.6 Unauthorised modification and manufacture of
spare parts
Modifications to the pump/installation are only
permissible after consultation with the manufacturer. Original spare parts and accessories authorised by the manufacturer ensure safety. The use of
other parts can nullify the liability from the results
of their usage.
2.7 Incorrect use
The operating safety of the supplied pump/installation is only guaranteed for conventional use in
accordance with Section 4 of the operating
instructions. The limit values must on no account
fall under or exceed those specified in the catalogue/data sheet.

3 Transport and interim storage
On receipt of the product, check immediately for
transport damage. If any transport damage is
found, initiate the necessary procedure with the
forwarding agent within the period specified.
CAUTION! Danger of property damage!
Incorrect transport and incorrect storage can
lead to damage to the pump.
• When transporting, only carry or suspend the
pump by the handle/holder. The cable should
never be used for lifting!
• When transporting and storing the pump, protect it against moisture, frost and mechanical
damage.
4Intended use
The submersible pumps Wilo-Drain STS 65 are
suitable for pumping polluted water and sewage
containing air, long-fibre solids, light faeces or
sludge (up to 10 % dry mass).
They are used in:
• domestic and site drainage
• sewage and water management
• environmental and water treatment technology
• industrial and process engineering
As a rule, the pumps are used in standard sumps:
• Single pumping station: diameter up to Ø1.5 m or
1 m x 1 m
• Double pumping station: diameter up to Ø2.5 m or
2 m x 2 m
Operating mode S3-25 % means over a period of
10 minutes:
• Operation time 2.5 min.
• Standstill time 7.5 min.
In this operating mode, the pumps can be operated with/without cooling jacket with the motor
on the surface and with the following switching
levels.
• Switch-off level: top of pump housing
• Switch-on level: top of motor
If used in basins with bigger cross-sections (e.g.
rainwater storage basins), the pumps
• must be operated submerged without cooling
jacket,
• submerged or on the surface with cooling jacket.
DANGER! Mortal danger through electric shock!
The pump must not be used for draining swimming pools, garden ponds or similar installations
if there is someone in the water.
WARNING! Health hazard!
Owing to the materials used, the pumps are not
suitable for potable water! Unpurified wastewater is a health hazard.
CAUTION! Danger of property damage!
Unpermitted substances in the fluid can destroy
the pump. Abrasive solids (e.g. sand) increase
pump wear.
Pumps without an Ex certificate are not suitable
for use in potentially explosive areas.
Correct use of the pump/installation also includes
following these instructions.
Any use over and beyond these is interpreted as
incorrect use.
