Display

In addition to displaying the temperature compensated (25°C) resistivity in
megohms, the display also indicates operational modes and error
indicators. The following is what can appear on the display:

rEC

Note On initial start-up, the purity meter may display "Er.1". This is
caused by air in the cell and should soon be replaced by a resistivity
reading. If "Er.1" does not go out after the pump has run for a minute. or
if it appears any time while the EASYpure II RF is in operation, refer to
the Troubleshooting section of this manual.
Note When the unit is first put in Run Mode, the display will show 10.0
for a few seconds. This is an arbitrary number that indicates the unit is
running. Any number that appears after 10.0 indicates purity.
Note If the unit is in standby and power to the unit is turned off or lost,
the unit will return to standby once power is restored.
Note Do not put unit into Idle Mode or turn off the EASYpure II RF
during non-work hours. Doing so will allow bacterial growth and other
contamination of the water in the system. As a result, the system will
require a lengthy rinse-up period at the beginning of the work day to
achieve high-quality product water.
Since not all qualities of permissible feedwater will reach maximum
resistivity after one pass through the unit's cartridges (especially as the
cartridges near exhaustion), the EASYpure II RF has two operational
modes; run and standby.
In Run Mode, the pump continuously recirculates water through the
cartridges. It is recommended that the EASYpure II RF be left in the run
mode during the day. In Run Mode, the purity meter display indicates the
resistivity of the water available for draw off. Allow the water's resistivity to
rise to the desired purity before drawing off water.
