Section 2 General Information

2.1 Safety information

Please read this entire manual before unpacking, setting up, or operating this equipment. Pay attention to all danger and caution statements. Failure to do so could result in serious injury to the operator or damage to the equipment.

To prevent damage to or impairment of the device's protection equipment, the device may only be used or installed as described in this manual.

2.1.1 Use of hazard information

DANGER

Indicates a potentially or imminently hazardous situation that, if not avoided, can result in death or serious injury.

WARNING

Indicates a potentially or imminently dangerous situation that, if it is not avoided, can lead to death or to serious injuries.

CAUTION

Indicates a possible dangerous situation that can have minor or moderate injuries as the result.

Indicates a situation that, if it is not avoided, can lead to damage to the device. Information that requires special emphasis.

Note: Information that supplements points in the main text.

2.1.2 Precautionary labels

Observe all labels and notices attached to the instrument and/or delivery packaging. Personal injury or damage to the instrument could occur if not observed.

This symbol, if noted on the instrument, references the instruction manual for operation and/or safety information.

This symbol may be found on an enclosure or barrier within the product and indicates a risk of electric shock and/or death by electrocution.

Electrical equipment marked with this symbol may not be disposed of in European domestic or public disposal systems after 12 August 2005. In conformity with European local and national regulations (EU Directive 2002/96/EC), European electrical equipment users must now return old or end-of life equipment to the manufacturer for disposal at no charge to the user.

NOTICE

18-32 kg (39.7-70.5 lbs)

When carrying or transporting the instrument/instrument components and if the total weight is more than 18 kg, make sure that suitable lifting equipment is used and/or that the instrument/instrument components are carried by 2 people.

General Information

2.2 Application areas

Automatic sample removal and homogenization system for supplying the PHOSPHAX S sigma (total phosphorus), TOCTAX (total organic carbon, TOC) and astro TOC (total organic carbon, TOC) process photometers with samples from water containing solid particles with a diameter < 0.5 mm.

Any use other than use in accordance with requirements defined in the user manual leads to the loss of the warranty claims and can lead to personal injury and property damage, for which the manufacturer assumes no liability.

2.3 Functional description

A sampling probe is immersed in the water and draws only the sample volume required for the analysis without coming into contact with pumps. The sample is conveyed into a small storage vessel in the open loop control unit and is homogenized using an ultrasound generator.
