1. Safety
1.1 General
This Operation & Maintenance Manual contains basic information to be noted during
installation, operation and maintenance. It is therefore essential that the contractor read
the manual before installing and commissioning the pump/system as well as by the
relevant operating personnel/owner of the pump/system. It must remain accessible at
the dosing pump/system for reference at all times.
In addition to the general safety instructions under this main heading of Safety, the spe-
cial safety precautions outlined another section must also be observed.
1.2 Warning symbols used in this Operation & Maintenance Manual
This Operation & Maintenance Manual contains vital information, which may endanger
people, the environment and the dosing pump/system if disregarded. These statements
are identified by the following symbols:
DANGER!
Refers to an imminent danger.
Non-compliance can lead to death or serious injury.
WARNING!
Refers to a potentially hazardous situation. Non-compliance can lead to death or serious
injury.
CAUTION!
Refers to a potentially hazardous situation. Non-compliance can lead to minor injury or
property damage.
NOTICE!
or
INFORMATION!
Appear in conjunction with safety instructions, which may endanger the pump/system
and its operation if disregarded.
IMPORTANT!
Draws attention to supplementary information to make the work easier and ensure trou-
ble free operation.
Markings that are affixed directly to the pump, such as
• Cable markings
• Markings for process fluid connections
must be observed without fail and remain fully legible at all times.

1.3 Qualification and training of personnel
The personnel employed for installation, operation, inspection and maintenance work
must be qualified to do so. The areas of responsibility, competence and supervision of
the personnel must be precisely defined by the owner. Personnel who do not have the
required knowledge must be duly rained and instructed. If necessary, this training can
also be provided by the manufacturer/supplier on behalf of the dosing pump’s owner. In
addition, the owner of the system must ensure that the relevant personnel are fully fami-
liar with and have understood the contents of this Operation & Maintenance Manual.
1.4 Important safety instructions
When installing and using this electrical equipment, basic safety precautions should
always be followed, including the following:
READ AND FOLLOW ALL INSTRUCTIONS!
WARNING!
To reduce risk of injury, do not permit children to use this product unless they are closely
supervised at all times.
WARNING!
Risk of electric shock. Connect only to a grounding type receptacle protected by a
ground-fault circuit-interrupter (GFCI). Contact a qualified electrician if you cannot verify
that the receptacle is protected by a GFCI.
Do not bury the cord. Locate the cord to minimize abuse from lawn mowers, hedge
trimmers, and other equipment.
WARNING!
To reduce the risk of electric shock, replace damaged cord immediately.
WARNING!
To reduce the risk of electric shock, do not use an extension cord to connect the unit to
the electricity supply; provide a properly located outlet.
SAVE THESE INSTRUCTIONS!
1.5 Hazards due to non-compliance with safety instructions
Failure to comply with safety instructions may endanger not only people, but also the
environment and the dosing pump/system. Non-compliance with the safety instruc-
tions can lead to the loss of all entitlement to damages.
