The HI922 Autosampler is designed to automate a wide variety of potentiometric titrations in conjunction with the HI932 Automatic
Titrator. The HI922 allows users to perform high-speed analysis while obtaining accurate results with minimal user interference.
Sequence reports and individual titration reports can be transferred to a PC via a USB interface, saved to a USB storage device or
printed directly from the titrator.
A barcode reader, balance, external monitor and keyboard can be attached for added convenience.
The autosampler and the accessories are shipped in a single box containing:

3. SAFETY MEASURES
The following safety measures must be followed:
1. Ensure that the titrator and autosampler are turned off before connecting or disconnecting pump assemblies.
2. Verify that the pumps and the attached tubing are assembled correctly.
3.Always check that the reagent and waste bottles are placed on a flat, stable surface and the titration beakers are placed in the
tray.
4. Always wipe up spills and splashes immediately.
5. Avoid the following environmental working conditions:
• Severe vibrations
• Direct sunlight
• Atmospheric relative humidity above 95% non-condensing
• Environment temperatures below 10°C and above 40°C
• Explosion hazards
6. Have the autosampler serviced by qualified service personnel only.
7. Keep hands and objects clear of moving parts during operation.
In an emergency situation, the autosampler can be stopped immediately by pressing either of
the illuminated emergency stop buttons located at the top corners of the autosampler tower.
This action will immediately deactivate motors and pumps.
To reset the emergency stop, press and hold both emergency buttons for five seconds until the
status lights turn from red to yellow to green.

5.1. BURETTE ASSEMBLY
5.1.1. DISASSEMBLING THE BURETTE
The aspiration and the dispensing tubes have fittings and tube protectors. The aspiration tube is mounted on the left side and the
dispensing tube is mounted on the right side of the burette.
To remove the dispensing tube follow these steps:
• Remove the blue tube protector (A) by sliding it off the clear titrant tubing.
• Remove the tube lock (B) from the burette holder.
• Turn the fitting (C) counterclockwise to remove it from the burette holder.
• Slide the clear titrant tubing through the fitting.
8
To attach the dispensing tube, follow these steps:
• Insert the flat-shaped end of the titrant tubing into the valve outlet (A) and screw the fitting clockwise to tighten. The highest of
the 9 cuts should be vertical in the final position.
• Straighten out tube up into the vertical position to enter the highest cut of the fitting (C).
• Attach the tube lock fitting (D).
• Attach the blue tube protector (E) by sliding it over the clear titrant tubing, the protector will be positioned in the tube lock fitting
ASSEMBLY
5.1.2. ASSEMBLING THE BURETTE
5.2. ATTACHING THE CABLE CARRIER
To attach the cable carrier remove the three (3) screws from the top rear panel (A). Align the screw holes on the cable carrier (B) to
the rear panel and tighten the screws.
9
ASSEMBLY
10
5.3. SETTING UP THE DISPENSER HEAD
To set up the dispenser head follow these steps:
• Release the clips from the cable carrier by using a flat head screwdriver.
•Insert electrode, temperature sensor, stirrer, and aspiration tube (optional) into the dedicated holes in the electrode holder
Push them down until they are in a stable position.
• Insert burette and auxiliary tubing into the appropriate holders.
• Close clips on cable carrier once all cables and tubing are positioned.
ASSEMBLY
5.4. CONNECTING PUMP TUBES
For Reagent Addition Operation:
• Connect the dispensing tubing to the left side of the peristaltic pump.
• Connect the reagent container tubing to the right side of the peristaltic pump.
For Waste Aspiration Operation:
• Connect the waste container tubing to the left side of the peristaltic pump.
• Connect the aspiration tubing to the right side of the peristaltic pump.

7.1. REPLACING PERISTALTIC PUMP TUBING
Peristaltic pump tubing wears over time and will occasionally require replacement. To replace tubing:
MAINTENANCE
7. MAINTENANCE
• Pull the clear plastic cover off of the pump (1)
•Remove the plastic rotor and tubing (2)
•Thoroughly grease the outside of the replacement tube and the rotor's rollers
•Wrap the replacement tubing around the rotor and press into the pump housing (3). The tubing in contact with the rollers will
need to be compressed with a finger in order to fit in the housing
• Replace the clear plastic cover
15
MAINTENANCE
WARNING! Turn off the autosampler and disconnect from the titrator before adding or removing pumps! Failure to do so could cause
damage to the pump and/or autosampler.
7.2. REMOVING A PUMP
•Remove the 4 screws holding the pump in the autosampler tower (1).
• Pull the pump out (2) of the tower slightly so that the pump’s side cover can be removed (3).
•Disconnect the pump's electrical connection by holding down the connector release tab (4) while pulling the connector away
from the circuit board (5).
• Pull the pump out of the autosampler tower.
• If the pump's bay is no longer being used, replace the side and back covers and fasten with the 4 screws.
7.3. ADDING A PUMP
Peristaltic pumps can only be connected to bay #1, #2, and #3. Membrane pump can only be connected to bay #4.
• Remove the 4 screws holding side and rear covers of the pump bay.
• Insert the pump into the rear of the autosampler tower.
•Once inside the tower, pull the pump's electrical connector out of the side of the tower. Push the connector into the circuit board
with the push-tab facing the outside of the tower.
• Replace the side cover. You will need to pull the pump out of the tower slightly.
• Fasten the pump in place with 4 screws.

The HI922 firmware can be upgraded via the USB connector. The current firmware version is displayed on the control panel during
boot-up and on the Autosampler Information screen. To upgrade the firmware:
1. Load the upgrade file into the root directory of a flash drive. Firmware files are named following “922v####.hex” format.
2. Power off the HI922 Autosampler using the power switch, but leave the cable connected to the HI932 Titrator.
3. Insert the USB flash drive with upgrade file in the HI922 USB port.
4.While holding down both emergency stop buttons, turn on the HI922 Autosampler. Keep the buttons pressed until the status
lights turn yellow. The control panel should display the message “Upgrading FW, please wait…”. After this message appears,
release the buttons and wait for the upgrading operation to be completed.
5.After the upgrade has been completed, the status lights will turn green and the control panel will display “Upgrade Complete”.
Remove the USB flash drive.
