Section 4 Installation
4.1 Analyzer inspection and unpacking
The instrument has been factory tested and checked prior to shipping. We nevertheless
recommend that you perform a visual inspection in order to ensure that it has not been
damaged. Any marked packaging is a potential sign of damage that may not be immediately
visible. Keep all packaging in the event of claims.
4.2 Instrument preparation
Before installing the analyzer, think about the following:
• Place the analyzer close to the sample point. This will allow the response time to be reduced.
• The sample should be homogenous and representative.
• The temperature of the sample should be between 5 and 45°C.
• The pressure of the sample should be between 0.2 and 6 bar and remain relatively stable.
• The solution should be free of particles. The sample lines should be in PE/PTFE/FEP (4x6
mm).
• Avoid any location with a corrosive atmosphere or subject to liquid spills.
• Chose a dry and dust-free location.
• The ambient temperature of the analyzer should not exceed 45°C. If the temperature is
below 5°C, the analyzer should be installed in a heated cabinet (not provided by Hach
Lange).
WARNING
The analyzer should only be assembled by qualified staff. Mains power should only be
connected once installation has been completed and checked.
WARNING
Do not connect power prior to mounting and plumbing the instrument.
CAUTION
Personal injury hazard. Instruments or components are heavy. Use assistance to install or
move. Make sure that the wall mounting is able to hold 4 times the weight of the equipment.
