This instruction handbook is part of the technical documentation from ANDRITZ for the machine. It is intended to provide the operating company with the essential knowledge for safe, proper and economical use of the machine supplied by ANDRITZ. Paying at- tention to these instructions helps prevent hazards, reduce repair costs and downtime, and increase the reliability and service life of the machine.
Centrifugal pump ACP STANDARD, C-01-000000 Standards and guidelines The pump is delivered together with a CE declaration of conformity according to Ma- chinery Directive 2006/42/EC Annex II, 1.A. It is confirmed that harmonized European standards EN 809 and EN ISO 12100, Parts 1 and 2, have been observed. Any elec- trical equipment supplied (motor, measuring instruments, etc.) has CE marking if it falls within the scope of a directive, for example the low-voltage or EMC Directive.
• Unauthorised structural changes to the machine/system. • Failure to observe the maintenance and upkeep instructions. • Use of non-original spare parts. In the event of a warranty claim, ANDRITZ reserves the right to assess damage to the machine/system. Service address Our service department is available for ordering spare parts, for troubleshooting and for extensive maintenance and repair work.
Supplementary safety notes relating to individual tasks are set out in the individual chapters of the instructions. These are highlighted in the text by special warning no- tices. Safety notes for components not supplied by ANDRITZ are contained in the subsup- plier documentation. These safety notes supplement the ANDRITZ instructions.
The machine may only be used for the process described in the chapter "Application area". Any other use or secondary use is considered improper use. Any modifications to the scope of delivery not approved by ANDRITZ qualify as im- proper use. Proper use includes compliance with the installation, operating and instruction hand- book.
Centrifugal pump ACP STANDARD, C-01-000000 General information about machine safety The machine/system is designed in accordance with state-of-the-art standards and the recognised safety rules. Nevertheless, its use may constitute a risk to life and limb of the user and of third parties, or cause damage to the machine/system and to other material assets.
In addition, ANDRITZ recommends mounting the following devices, symbols and signs in as far as these are not already included in the local regulations.
Centrifugal pump ACP STANDARD, C-01-000000 • Familiarize yourself with the function and any failure of monitoring equipment (log book) before starting work. • No smoking in the vicinity of the machine/plant. • Wear personal protective apparel when working on the machine/plant. •...

Centrifugal pump ACP STANDARD, C-01-000000 Personal protective equipment Personal protective equipment must be used and carried along in accordance with the country-specific regulations or the regulations of the system operator. Wearing safety shoes and eye protection should be mandatory on the entire plant grounds. In addition to the applicable regulations, we recommend using the following protective equipment for certain tasks.
Centrifugal pump ACP STANDARD, C-01-000000 2.10 Safety at the installation site The machine does not have a permanent workstation. Presence at the machine is only necessary for inspection and maintenance tasks. All operating and maintenance areas of the machine must have adequate lighting and ventilation (industrial lighting).
2.14 Welding work In general, welding work is only permitted after consultation with the national authorit- ies and after consultation with ANDRITZ. Welding work that is described in detail in the maintenance instructions is exempt from this rule. The relevant safety regulations must be observed for welding work.
Centrifugal pump ACP STANDARD, C-01-000000 2.15 Fluids (liquids, gases, steam or smoke) In various media, in case of a longer standstill, unwanted chemical reactions can oc- cur and vapours harmful to health can be generated. After prolonged stoppages, the machine must be thoroughly cleaned. Sufficient ventilation and degassing must be ensured.
Centrifugal pump ACP STANDARD, C-01-000000 2.17 Chemicals Chemicals can damage the skin and cause the formation of hazardous gases, which may subsequently cause breathing problems. Personnel handling these materials must not be allergic to them. Safety data sheets If chemicals are used, the measures prescribed in the safety data sheets of each chemical must be adhered to.
The centrifugal pump is used to convey the specified media or materials in compliance with the manufacturer's instructions. If modifications are planned or the pump is to be used for a non-specified application or in an ATEX environment, ANDRITZ must be contacted.
