4 Assembly
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.
