Section 4 Installation
WARNING
The analyzer should only be assembled by qualified staff. Mains power should only be
connected once installation has been completed and checked.
4.1 Analyzer inspection and unpacking
The analyzer 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.
Open the box. Take the packing list from the box and check the presence of all the items
selected. If any parts or accessories are missing, refer to your distributor or to Hach Lange.
4.2 Analyzer 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 50°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.
• Sample lines should be in PE/PTFE/FEP (4 x 6 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).
