Guide for switching from Hach Series 5000 to Hach 5500sc
1 Introduction
Twenty years after launching the Silica analyzer model 5000, Hach has introduced to the market a new analyzer with innovative solutions. The aim of this guide is to help you make the transition from the Series 5000 Analyzer to the new 5500sc Silica Analyzer.
2 Why switch from Hach 5000 to Hach 5500sc?
There are several reasons to switch from the Series 5000 to the 5500sc. Even if you are continuing to use the same measurement operations and principles, the new generation provides benefits that will prove advantageous.
Two analyzers are shown side-by-side: the Series 5000 Silica on the left and the Hach 5500sc on the right.
| Series 5000 Silica | Hach 5500sc |
|---|---|
| 2.9 liters reagents every 30 days 1 bottle/month @ 8.8 min cycle time |
Extended reagent replacement intervals and low reagent consumption 1 bottle (2-liter) every 90 days @ 15 min or 60 days @ 9.5 min |
| Fixed measurement cycle | Configurable measurement cycle from continuous up to 240 mins (Interval Mode) |
| 2.9 L PET bottles | 2 L bottles with quick-connect, including pre-installed tubing and color coding - Reduces time maintaining the unit and reduced risk of contact with chemicals |
| No predictive diagnostic tool | Predictive diagnostics (PROGNOSYS™) and built-in help function. Reduces risk of unexpected failures and unit downtime |
| 8-channel external sequencer | Optional built-in sequencer, up to 6-channels Lowers costs via sampling points and eliminates cost for an external sequencer (up to $ 6,000) |
| Grab Sample In | Grab Sample In and Grab Sample Out Enables quick QC validation in addition to normal process monitoring |
| Pressurized reagent delivery system NO PUMPS | Same principle with improved design. Built-in air compressor requires no external air supply |
| Colorimetric analysis method at 810 nm. | Same method |
| 3 reagents and one standard | Same number, but different reagent concentrations |

5 Step 1- Removing the Hach 5000 analyzer
5.1 Save the analyzer setup
Perform the following actions:
- Perform an analyzer printout: (SETUP/PRINT SETUP/ENTER)
- Back up your Hach 5000 analyzer setup, including:
- High/Low Alarm values
- Alarm relay identification
- Recorder max concentration
- 4-20mA output ranges
- Digital com settings
- Disconnect the analyzer from its power source.
A sample analyzer setup printout is displayed, showing alarm values, recorder settings, and date/time.
5.2 Remove bottles
- Remove the 3 reagent bottles.
- Follow regulations in place for the reagents' elimination/destruction.
- Remove the silica standard solution.
- You can keep the solution, but discard the bottle – the 5500 has different bottle types.
Two reagent bottles and a bottle of silica standard solution are shown, indicating they need to be removed.
5.3 Remove all electrical connections
- 115/230 VAC power line
- High voltage relays
- Low voltage relays
- Recorder output
- RS 232 connection
A diagram illustrates the electrical connections of the Hach 5000 analyzer, showing power, relays, recorder output, and RS232 connections with corresponding wire colors.
5.4 Remove all hydraulic connections
- Sample in/out
- Cabinet/Sample Drain
- Air purge
- The sample heater, Model 48500, can be removed as long as the sample temperature is above 5°C (41° F).
- The installed sample pressure conditioning kit (Model 45983-00) can be removed – the 5500 uses a different kit.
A diagram shows the hydraulic connections of the Hach 5000 analyzer, labeling sample inlet/outlet, drains, air purge, and indicating components like the sample heater and pressure conditioning kit.
5.5 Remove the Hach 5000 analyzer unit
- Remove the six screws.
- Remove the analyzer, being careful of its weight: 37kg (81 lb).
The Hach 5000 analyzer unit is shown, highlighting the need to remove six screws for removal.
6 Step 2 - Installing the Hach 5500sc
6.1 Wall mount installation
Follow instructions 1B to 4B on document: Illustrated user instructions to mount the analyzer on a wall, on panel or on table.
An illustration depicts the Hach 5500sc analyzer being mounted on a wall.
6.2 Panel mount installation
- Install the optional adapter plate Model 6791000 with the six screws provided.
- Follow instructions on document: Adapter Plate User Instructions for Polymetron Analyzer.
An illustration shows the optional adapter plate being installed for panel mounting the Hach 5500sc analyzer.
Follow instructions 1C to 4C on document: Illustrated user instructions to mount the analyzer on a wall, on panel or on table.
6.3 Panel mount
Follow instructions 1A on document: Illustrated user instructions to mount the analyzer on a wall, on panel or on table.
An illustration shows the Hach 5500sc analyzer mounted on a panel.
7 Connecting the Hach 5500sc hydraulics
7.1 Identify hydraulic connections
Identify the hydraulic inlet/outlet connections for one to six sample streams.
A diagram identifies the hydraulic inlet and outlet connections for up to six sample streams on the Hach 5500sc.
7.2 Connect samples and drain lines
- Use the supplied tubing (6 mm), Y-strainer with filter and pressure regulator to plumb the drain and the sample to the analyzer.
- The sample line tubing that goes into the plumbing access ports must be 6 mm.
- Tubing of 1/4 in. may be used for the sample line up to the valve and y-strainer, but not into the analyzer's plumbing access ports.
- See DOC023.97.80240 for more information.
A diagram illustrates the connection of sample and drain lines using supplied tubing, a Y-strainer with filter, and a pressure regulator.
7.3 Connect sample stream
Install each sample line into the center of a larger process pipe to minimize interference from air bubbles or bottom sediment. See figure on left.
An illustration shows how to connect the sample stream into a larger process pipe to minimize interference.
7.4 Set the bypass flow rate
- The bypass flow can be adjusted when the analyzer is in shutdown mode. Adjust the flow rate of the sample bypass line with the flow valve as shown at left.
- Use an external meter to measure the flowrate of the sample bypass line.
- For faster response to changes in the process stream, increase the sample bypass line flow rate when the process stream is far from the analyzer.
A diagram shows how to adjust the bypass flow rate using a flow valve and suggests using an external meter.
8 Connecting the Hach 5500sc electrical connections
Follow procedure on pages 11-17 of the operation manual.
9 Installing analyzer bottles and stir bar on the Hach 5500sc
