Controls and Normal Operation
Standby Mode
In Standby ("SbY") Mode, the pump will operate for ten minutes out of
every hour (i.e 50 minutes off, 10 minutes on), during which time the
display reads "rEC" which indicates recirculation. Every fourth time that
the pump turns on, the UV lamp will also turn on for 10 minutes (i.e 3
hours 50 minutes off, 10 minutes on). This will allow the unit to produce
high quality water quickly upon being placed in the Run Mode and
prolong the life of the UV lamp. It is recommended that the EASYpure
RODI be placed in the Standby Mode during non-work hours. At the end
of the work day, press the STANDBY switch to place the unit in Standby
Mode. "SbY" will appear on the display. Also in the Standby Mode, the
RO operation automatically turns on to fill the reservoir tank as needed.
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.
s
Flush Mode
Note Each time the RO system automatically turns ON, in Run or
Standby mode, the RO membrane will be flush water to the drain for 30
seconds prior to filling the tank.
Manual Flush (Reverse Osmosis
Pressing the Flush switch once will initiate a one minute flush of the RO
membrane. During this one minute flush, water is sent to drain through
Membrane)
the drain tubing and the display will show FL1. Pressing the Flush switch
twice will initiate a five minute flush of the RO membrane. During this
five minute flush the display will count down FL5, FL4, FL3, etc. After
the timed flush has ended, the EASYpure RODI will return to the mode
("IdL", Run or "SbY") it was in when the flush was initiated.
Automatic Flush (Reverse
In the Run Mode, the EASYpure RODI will initiate a one minute
Osmosis Membrane)
automatic flush of the RO membrane once every twenty-four hours of
operation. This prevents buildup on the RO membrane. A microcontroller
timer in the EASYpure RODI counts the hours power is applied to the
unit. When the timer reaches twenty-four hours, the EASYpure RODI
initiates a one minute flush if the unit is in the Run and Standby Modes.
If the unit was in Standby, the automatic flush will occur immediately after
the START/STOP switch is pressed and Run Mode entered. The timer
will reset to zero when the one minute automatic flush is completed.
Idle Mode ("IdL")
"IdL" indicates the unit is powered and waiting to be placed in Run,
Standby or Flush Mode.
