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
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.
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.
NOTICE
Indicates a situation that, if it is not avoided, can lead to damage to the device. Information that
requires special emphasis.
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.
Note: You obtain instructions on the correct disposal of all (marked and not marked) electrical products that
were supplied or manufactured by Hach-Lange at your relevant Hach-Lange sales office.
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.
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.
NOTICE
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.

Section 3 Installation
DANGER
Only qualified experts may conduct the tasks described in this section.
DANGER
Select a suitable attachment point for the instrument.
Plan out the mechanical mount·before positioning poles or drilling holes. Make sure the mount
has a sufficient bearing capacity. The dowels must be selected and authorized according to the
condition of the wall.
The manufacturer shall accept no liability if the instrument is installed incorrectly.
Plan how to lay cables and tubes and their path in advance. Lay the tubes, data cables and
power cables without any bends and so they do not pose a tripping risk.
Do not connect the electrical supply to the mains·until the instrument is completely wired and
protected against short circuits.
Sufficiently protect the electrical power supply against short circuits.
For the external power supply, always connect a residual-current circuit breaker·(trip current
max.: 30 mA) between the mains and the system.
If the instrument is to be installed outdoors, connect a surge arrester between the mains and the
system.
Products intended by the manufacturer for outdoor use offer a higher level of protection against
the penetration of liquids and dust. If these products are connected to a mains outlet with a cable
and plug·rather than a permanently connected cable, the plug and outlet are much more
susceptible to liquid and dust penetration. The operator must sufficiently protect the plug and
outlet against liquid and dust penetration in accordance with local safety regulations. If the
instrument is to be used outdoors, it must be connected to a suitable outlet with a protection type
of at least IP44 (splash protection).
WARNING
Electrical and fire hazards. Only use the mains cable supplied. Only qualified experts may
perform the tasks described in this section of the manual, while adhering to all locally valid safety
regulations.
NOTICE
Protect the instrument from extreme temperatures from heaters, direct sunlight and other heat
sources.
CAUTION
Beware of the weight (open loop control unit: approximately 12 kg; sampling probe up to
approximately 22 kg) of the instrument and the probe. Do not attempt to carry the instrument and
probe without assistance. Use only suitable lifting devices for the transport.

Installation
3.1.3 Install the open loop control unit
Make sure that an area of 5 cm is kept free around the entire instrument to enable air to
circulate (distance from the wall of the building, cable channel etc.).
NOTICE
Install the open loop control unit in a dry location out of direct sunlight.
NOTICE
The Teflon sample lines must be laid without sharp bends. Shortening or extending the lines will
lead to problems when the samples are transported.
Each process instrument must have a separate drain tube!
The individual device drains may only be combined in a larger drain pipe with regular water
throughput.
