read by the service technician and the responsible operator before
installation and commissioning starts.
It is not only the general safety instructions listed in this chapter that
must be respected but also the special safety instructions mentioned in
following chapters. They are indicated with a danger symbol as follows.

2.1 SYMBOLS USED IN THESE INSTRUCTIONS

General danger for user.
Danger due to electrical voltage.
Non-observance of the safety instructions can result in damage to
product/installation.
Refers to additional requirements, that the pump should comply to
when operated in hazardous areas.
This is not a security symbol. It is a note that gives additional useful
information about the way to use the pump.

2.2 PERSONNEL QUALIFICATION

Personnel involved in operation, installation, inspection or
maintenance of the pump and accessories must be adequately qualified.
Qualification, knowledge evaluation and personnel supervision must be
strictly handled by the pump owner. If necessary, WILO or one of its
representative can perform adequate training. Plant management must
ensure that contents of the operation instructions are fully understood
by anyone who will use this pump.
2.3 DANGER IN 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 product/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 product/installation functions,
- Failure of required maintenance and repair procedures,
- Danger to persons from electrical, mechanical and chemical,
thermal risks, ...
- Property damages,
- Loss of ex-proof protection,
- Risk of environmental pollution.

2.4 SAFETY INSTRUCTIONS

2.4.1

SAFETY INSTRUCTIONS FOR THE OPERATOR

OPERATION ON THE PUMP SET :
Make sure that electric power is switched off before maintenance
operations starts. Electrical protection should not be removed while
pump is running.
Empty pump casing and isolate piping before starting dismantling
of pump. If dangerous liquid was pumped the pump should be
decontaminated and cleaned prior to dismantling.
HANDLING OF COMPONENTS :
Some machined parts may have sharp edges. Wear safety gloves
and use necessary protections to handle them.
A lifting device must be used to lift parts exceeding 25Kg. Use
lifting device in accordance with local regulations.
HOT OR COLD PUMP PARTS:
Avoid accidental contact with very hot or very cold components.
Actions must be taken if their surface temperature is higher than 68 °C
or below -5°C : (pump or accessories). If a complete protection is not
possible, the access to the machine must be limited to maintenance staff
only. A clear visual warning panel must be attached in the immediate
area to indicate the danger.
HAZARDOUS LIQUIDS:
When the pump is handling some dangerous liquids, a special care
must be taken to avoid exposure to the liquid. Make sure the pump is
set in an appropriate location and access to the pump must be limited.
Operators should be trained to potential risks.
If the liquid is flammable and/or explosive, strict safety procedures
must be applied.
2.4.2

SAFETY INSTRUCTIONS FOR THE EQUIPMENT

Quick temperature changes of the liquid contained in the pump
should be avoided. A thermal shock may drive to damages or
destruction of components, creating leakages.
Ensure that pump flanges do not support excessive external forces
when fastening piping flanges or after increasing of liquid temperature.
Do not use pump as a support for piping. If expansion joints are used
they should be equipped with axial movement limiting device.
Before checking direction of rotation make sure that no parts could
be ejected from shafts (pins, keys, coupling element ...). Several pump
types will be damaged if started in the wrong direction of rotation
(screwed impeller design). The flexible coupling of a pump set must be
disconnected before first start up to check direction of rotation.
