Analyzer Preparation

Thermo Scientific Orion 2120XP Calcium Hardness Analyzer User Guide
Refer to the
Appendix, Mounting Dimensions
section.
Warning:
Do not connect power prior to the mounting and plumbing of
the analyzer.
• Select a site for the analyzer that allows it to be permanently bolted
with ample height for atmospheric drain operation. Be sure that there is
ready access to the electronic controls, calibration port and electrodes.
• A clearance of 15 inches (about 40 cm) must be allowed above the
flow cell calibration port. Insert the pipet vertically (not angled) during
the calibration.
• The analyzer location must permit connections to a sample line, drain
and AC power supply and any connections for output devices.
• The analyzer should be mounted as close to the sampling point as
possible. This ensures the fastest possible response to a changing sample
condition. Refer to the
Appendix, Sample Conditions
section.
• For proper flow cell operation, the analyzer must be installed straight
and level upon its mounting location. Failure to level the analyzer may
cause poor siphoning in the flow cell.
1. Prepare the mounting holes. Carefully lift the analyzer and bolt it into
place. Do not lift the analyzer by holding on to any of the plumbing or
fluid handling components.
2. Connect a waste line to the outlet of the analyzer, which is 3⁄4 NPT
male. The waste line should be connected to a drain of sufficient
capacity, 0.5 inch (1.27 cm) OD is recommended.
3. Connect a sample line to the inlet of the analyzer, which is 1⁄4 NPT
female. It is recommended that a shutoff valve be installed at the
sampling point.
4. The analyzer must be mounted and leveled vertically for proper
operation.
