Dispensed amount is too small • UF-Module blocked
• Feed water pressure too low
• Internal pressure too low
• Volumetric Dispense out of
Tolerance
• Replace UF-module
• Increase the feed water pressure
• Readjust pressure reducer
• Contact Thermo for volume
calibration
Wrong time or date • Time zone
• Summer/winter time
• Reset time and date
Wrong language • Wrong language set • Correct the language setting
Error message:
“Limit value feed”
• Feedwater conductivity too
high
• Limiting value set too low
• TOC selected on non-TOC
units
• Check the pretreatment
• Check and suit the limiting
value setting
• Turn LF3 to off
Display reads +IN • Measuring cell cable break • Replace measuring cell
Error message:
“Lim. va.pure w.”
• Ultrapure cartridge
exhausted
• Limiting value set too low
• Replace with new ultrapure
cartridge
• Check and set the limiting
value
Error message:
“UV-duration”
• UV-Lamp operating time has
been exceeded
• Replace the UV-lamp
• Re-set the operating time
counter
Error message:
“UV-intensity”
• UV-Lamp intensity no
longer sufficient
• UV-Sensor is dirty

value
Error message:
“max.Temperature”
• The temperature in the
system is too high
• Interval pump time too long
• Limiting value set too low
• Feedwater temperature is too
high
• Reduce the temperature by
running water off
• Reduce interval pump time
• Check and suit the limiting
value
• Reduce the feedwater
temperature
Error message:
“Measuring cell LF1”
• Measuring cell cable break
• System control defect
• Conductivity of ultrapure
water outside of the
measuring range
