Thermo Scientific
Display
Refer to Figure 6-1. In addition to displaying the temperature
compensated (25°C) resistivity in M ohms-cm, the display also indicates
operational modes and error indicators. The following is what can appear
on the display:
Three LEDs illuminate to provide system operational status as follows:
•
RO System Operating: Green LED ON - RO Operation is ON; LED
OFF - RO Flush or RO Operation is OFF.
•
Low RO Purity: Red LED ON - % rejection between incoming water
and product water is lower than expected; LED OFF - % reject is
good.
•
Replace RO Prefilter: Red LED ON - Unit has been in service for 6
months, replace RO prefilter; LED OFF - replace prefilter as needed
and reset timer.
Note When the RO operation is automatically turned on, only RO water
that is above the specified % rejection setting (factory set to 75%) will be
put into the tank. Anytime the RO purity falls below the % rejection
setting the water will be diverted away from the tank and sent to drain.
