3. Tighten the cap on the bottle.
4. Repeat the steps for all three bottles.
5.2 Start the instrument
Note: To avoid back flow of the sample to the reagents, make sure that the pressure plate is securely attached.
1. Open the supply valve to the instrument.
2. Let the pressure in the tubes become stable.
Note: If leaks occur under pressure, examine all the connections. Secure connections until all leaks have
stopped.
3. Look at the bypass flow to the drain and adjust sample flow to the analyzer with the shut off valve.
Set the flow to 200-500 mL/min.
4. Turn on the power.
5. Select Prime>Prime All to do a prime cycle. Refer to
prime cycle is complete, the initial readings might not be accurate.
6. If the readings are not accurate, let the readings stabilize (1-12 hours) and then calibrate the
analyzer.
Note: In single-relay systems, the relay tube is active during this time.
Section 6 Operation
6.1 Use the menus
To enter any menu, push MENU. Use the arrow buttons to select an option, then push ENTER. Edit
a value when it flashes. Use the arrow buttons to change the digits. Push ENTER to move to the next
editable digit. To exit from any menu structure, push EXIT until the MENU button is no longer turned

English (default), Spanish, French and German
Displays/edits current status of Hold Outputs. If ON is selected, all alarms are disabled
and the recorder output level is held at its current level. The Alarm LED flashes. The
alarm lockout period is disabled after 30 minutes or if OFF is selected.
On or Off. Push EXIT to reject changes and return to setup. If Diag Output is on and the
optional Hach network interface is present, additional diagnostic data is sent via an SIO.
If the Hach network interface is present, the instrument outputs readings to an
AquaTrend Interface or MOD I/O regardless of the Diag Output setting.
On or Off. If the keyboard is locked out, no editing functions are allowed and all
changeable settings are disabled except Keyboard Lockout. Default is Off.
Sets the reaction delay time. This value is set at 200 seconds to let the instrument to
correctly measure fluoride in the presence of interferences such as aluminum. This time
can be further decreased if metals which typically include complex fluoride (including Al
and Fe) are not present. If the delay is removed, it causes low fluoride readings in the
presence of metals. For example, if 1 mg/L of Al is present, a 1 mg/L sample of fluoride
reads 0.3 mg/L at no delay and 0.6 mg/L with a 60 second delay. If the delay time is
changed, it affects reagent consumption.
Sets the power fail warning to On or Off. Press ENTER then use the arrow keys to
toggle between ON and OFF. Press ENTER to select. Press EXIT to reject changes and
return to Setup. If the power fail warning is already on and the power is interrupted, a
system warning will be triggered when power is turned on.
