For initial installation, complete the steps below. For replacement, refer to the documentation supplied with the desiccant cartridge.

1

Install by date (mm.yyyy = month and year)

2

Indicator (light blue = not expired, white = expired)

3

Transport safety protection

1. Look at the install by date on the packaging. Refer to Figure 4. Do not use if the current date is past the install by date.
2. Make sure that the indicator on the new desiccant cartridge is light blue. Refer to Figure 4.
3. Install the new desiccant cartridge. Refer to the illustrated steps that follow.
   
   

Replace the cleaning lid screws

NOTICE
Do not overtighten the screws or breakage will occur. Hand tighten the screws

If the sample temperature is 40 to 60°C (104 to 140°F), the cleaning lid screws will become hot. To prevent burns, replace the standard cleaning lid screws with the cleaning lid screws and washers for hot water. Refer to Figure 1 for the location of the cleaning lid screws.

Install the service bracket

The service bracket holds the process head (or the optional automatic cleaning module) when it is not installed on the instrument.

Refer to Installation overview to install the service bracket the correct distance from the instrument. Refer to the illustrated steps above to install the service bracket.

Install the flow sensor

(Optional)
The optional flow sensor identifies if the sample flow is within specifications. A warning shows on the controller display and the status indicator light when a no flow, low flow or high flow warning occurs.
Install the optional flow sensor. Refer to the documentation supplied with the optional flow sensor.

Install the automatic cleaning module

(Optional)
The automatic cleaning module cleans the inside of the process vial at a selected time interval. Install the optional automatic cleaning module. Refer to the documentation supplied with the automatic cleaning module.

Connect to an SC controller

Personal injury hazard. Do not look into the vial compartment when the instrument is connected to power.

1. Get the latest software version from www.hach.com. Install the latest software version on the SC controller before the instrument is connected to the SC controller.
   Refer to the software installation instructions supplied in the box or supplied in the software download for the SC controller.
2. Remove power to the SC controller.
3. Connect the sensor cable to the quick-connect fitting of the SC controller. Refer to Figure 5. Keep the connector cap for later use.
   
4. Supply power to the SC controller.
   The SC controller looks for the instrument.
5. When the SC controller finds the instrument, push enter.
   On the main screen, the controller shows the turbidity value measured by the turbidimeter.

Plumbing

Plumb the instrument

Explosion hazard. Make sure that the drain tube is free of all obstructions. If the drain tube has a blockage or is pinched or bent, high pressure can build up in the instrument.

Personal injury hazard. The sample line contains water under high water pressure that can burn skin if hot. Qualified personnel must remove the water pressure and wear personal protective equipment during this procedure.

NOTICE
Do not let water get in the vial compartment or instrument damage will occur. Before the process head is installed on the instrument, make sure that there are no water leaks. Make sure that all tubing is fully seated. Make sure that the vial nut is tight. The full water pressure should be on the system, the water flow is on and no water leak on the glass vial is seen.

NOTICE
Hold the automatic cleaning module vertically when it is installed on the instrument or the vial can break. If the vial breaks, water will get in the vial compartment and instrument damage will occur.

NOTICE
Before the instrument is plumbed, make sure that the desiccant cartridge and vial are installed.

NOTICE
Based on the environmental conditions, is necessary to wait a minimum of 15 minutes to let the system become stable.

Items supplied by the user:

• Flow shutoff valve
• Tubing⁶
• Tubing cutter

⁶ Refer to Specifications for the tubing requirements.

1. Plumb the instrument. Refer to the illustrated steps that follow and Figure 6.
   Note: To plumb the instrument with accessories, refer to the documentation supplied with the accessories.
   Note: Use the opaque tubing accessory supplied from HACH accessory to prevent the bacteria growth.

2	Sample inlet	5	Flow shutoff valve
3	Sample outlet

Set the flow rate

1. Measure the flow with the flow regulator fully open. Make sure that the flow is in the middle of the flow specification. Refer to Specifications
2. Slowly close the flow regulator until the flow decreases by 20 to 30%.
   Note: The flow regulator causes back pressure in the tubing and decreases the quantity of bubbles that can form in the vial.

User navigation

Refer to the controller documentation for keypad description and navigation information.
Push the RIGHT arrow key on the controller multiple times to show more information on the home screen and to show a graphical display.

Operation

Refer to the expanded user manual on the manufacturer's website to configure the instrument settings and to compare process and lab measurements.

Calibration

Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets (MSDS/SDS) for safety protocols.

The instrument is factory calibrated and the laser light source is stable. The manufacturer recommends that a calibration verification be done periodically to make sure that the system operates as intended. The manufacturer recommends calibration as local regulations require and after repairs or comprehensive maintenance work.

Use the optional calibration lid and a vial(s) with a StablCal standard or Formazin standard to calibrate the instrument. Refer to the Calibration lid documentation for more calibration procedures with and without RFID vials, 1-point and 2-point calibrations. As an alternative, use a syringe and StablCal standard or Formazin standard to calibrate the instrument.

Verification

Use the optional calibration lid and a sealed-vial 10-NTU StablCal standard (or a StablCal 10 NTU standard and a syringe) to do a primary calibration verification. As an alternative, use the optional calibration lid and the optional glass verification rod (< 0.1 NTU) to do a secondary calibration verification in the lower range of turbidity.

Maintenance

Burn hazard. Obey safe handling protocols during contact with hot liquids.

Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the document.

Personal injury hazard. Never remove covers from the instrument. This is a laser-based instrument and the user risks injury if exposed to the laser.

Personal injury hazard. Glass components can break. Handle with care to prevent cuts.

NOTICE
Do not disassemble the instrument for maintenance. If the internal components must be cleaned or repaired, contact the manufacturer.

NOTICE
