3General safety points
3.1 Dangers when properly used
DANGER!
Damaged instrument or cabling.
Touching damaged cables may lead to electrical shocks or death.
The instrument may be operated only when the cables are undamaged.
The instrument may be operated only if it has been properly installed or repaired.
DANGER!
Dangerous voltage inside the supplied mains device.
Touching a wet or damaged mains device may lead to electrical shocks or death.
Do not position the mains device in moist locations.
Do not operate the mains device if housing is damaged.
DANGER!
Damage to the instrument due to incorrect service voltage.
If the instrument is connected to an incorrect service voltage, the instrument can be dam-
aged.
The instrument may be connected only to voltage sources as specified on the rating
plate.
DANGER!
Rotating bottle centering device.
Reaching into the rotating bottle centering device may result in crushing of hands and
fingers.
Do not reach into the rotating bottle centering device.
Start a measurement only when the water bath cover is closed.
DANGER!
Missing Instruction Manual after the instrument changes hands.
Operating the instrument without knowledge of the Instruction Manual may lead to injuries
to persons and damage to the instrument.
If the instrument changes hands, always include the Instruction Manual.
If the Instruction Manual is lost, you can request a replacement.
Registered users can download the current version at www.photometer.com.
CAUTION!
Water escaping from leaking instrument or water connections.
Escaping water can lead to flooding of the space and may cause material damage to the
building and furnishings.
Check the sealing of the inlet and outlet.
Never leave the instrument unsupervised.

General safety points Instruction Manual LabScat 2
12112E/2 15
CAUTION!
Penetration of moisture as well as condensation on the electrical components dur-
ing operation.
If moisture enters the instrument, the LabScat 2 can be damaged.
The USB interface cover must always be attached during operation.
If the instrument is operated with a water temperature which is lower than the ambient
temperature, the instrument must remain switched on.
CAUTION!
Penetration of moisture as well as condensation on the electrical components dur-
ing servicing duty.
If moisture enters the instrument, the LabScat 2 can be damaged.
Work on the inside of the instrument may be performed only in a dry room and at room
temperature. The instrument should be at operating or room temperature (avoid con-
densation on optical and electrical surfaces).
CAUTION!
The use of aggressive chemicals when cleaning.
Use of aggressive chemicals can cause damage to instrument components.
Do not use aggressive chemicals or cleaning agents when cleaning.
Should the instrument come in contact with aggressive chemicals, clean it thoroughly
with a neutral cleaning agent.
WARNING!
Unpleasant odors in the water bath
Stagnant water or residual moisture in the water bath can lead to unpleasant odors.
Empty and clean the water bath after every use.
Do not close the cover on the water bath when not in operation.

Instruction Manual LabScat 2 General safety points
16 12112E/2
3.2 Residual risk
WARNING!
According to the risk assessment of the applied safety directive DIN EN 61010-1,
there remains the risk of a faulty measuring value display. This risk can be reduced
with the following measures:
Use an access code to prevent unauthorized persons from changing parameters.
Perform the specified servicing duties.
3.3 Warning and danger symbols on the instrument
WARNING!
There are no warning or danger symbols on the instrument.
Users must ensure that they observe the safety measures as specified in the Instruction Man-
ual at all times when working with the instrument and its peripheral equipment.
The following sections must be internalized:
Section 1.11
Section 1.12
Section 1.13
Section 3.1
Section 3.2
Observe safety pointers when performing the described procedures.
Observe local safety pointers.

Assembly Instruction Manual LabScat 2
12112E/2 17
4Assembly
4.1 Location selection
Note the following points for the operating location:
The photometer is set up on a table or an even surface.
Electrical supply and water supply must be ensured.
The instrument should not be exposed to direct sunlight during measurement, as the
measurement can be skewed by excessive external light.
The water supply must be ensured as described in the technical data. The continual wa-
ter circulation during operation ensures that the water bath is always filled, also for dif-
ferent water bottle sizes.
Water outlet must be able to take place unhindered, as otherwise the water bath may
overflow and flood the inside of the instrument.
4.2 Assembly and water bath connection
CAUTION!
Loosely fastened hoses on the photometer.
If the hoses become loose from the photometer, the space can flood and cause material
damage to the building and furnishings.
All hose junctions have to be secured with hose clamps. The connections should be
checked about two weeks after installation to ensure they are sealed.
Cleaning and other activities are easier if the instrument can be moved without remov-
ing the hoses. Therefore, ensure the hoses are sufficiently long.
The regulator valve is designed for the maximum pressure of 0.6 MPa (6 bar). However,
we recommend regulating the flow rate directly at the water valve during water with-
drawal. Ensure that the feed hoses are specified for the maximum pressure.
The water quality is monitored by the instrument. Monitoring is based on the measuring
value of 90°, which is constantly measured, regardless of whether a measurement value
acquisition was initiated. The lowest measuring value of the last 15 minutes is the water
value.
Caution: If a sample with high turbidity is in the LabScat 2 for longer than 15 minutes, a
WATER QUALITY warning is triggered. The warning can be deleted by removing the
sample from the measuring instrument.

al. This protects the water bath and bottle cen-
tering device from dirt particles.

4.3 Filling the water bath
The regulator valve must be pressed in completely to fill the water bath.
The water bath should not be without water circulation for a long period of time.
The continual water circulation ensures that the water bath is always filled, also for dif-
ferent bottle sizes.
The water bath must be cleaned periodically.
