Section 6
Controls

Standby ("SbY")

In STANDBY ("SbY") mode, the pump will restart for ten minutes out of
every hour (i.e 50 minutes off, 10 minutes on). The display reads "rEC"
which indicates recirculation. This will allow the unit to produce high
quality water quickly upon being placed in Run Mode. It is recommended
that the EASYpure II RF be placed in Standby Mode during non-work
hours. At the end of the work day, press the STANDBY switch on the
front of the EASYpure II RF to place the unit in STANDBY mode for the
night. "SbY" will appear on the display.

Idle Mode ("IdL")

"IdL" indicates the unit is powered and waiting to be placed in Run or
STANDBY mode.
