Initial Set-Up and Operation:
The RO system is fully assembled and integrated into the compressor package.
As delivered, the new RO membrane contains a FDA approved preservative solution to prevent
microbiological growth and freezing. This preservative will be flushed during the initial hours of operation.
Adjusting the cycle timer.
The frequency of fill-up cycles ultimately depends on the quality of the water within the main reservoir.
Cycle times of 3 days “off” and 3 minutes “on” typically yield acceptable results – injection water TDS level
is held below 60ppm and no suspended solids form. To conserve water, longer “off” time cycles may be
used if the resulting injection water quality does not exceed 60 ppm and no suspended solids form.
Adjustment of the timer for 3 days “off” and 3 minutes “on” cycles is accomplished by interconnecting PLC
terminal 4, 6, 7, and 9 with jumper wires. Refer to Fig 8-1 for PLC connections and cycle-time
combinations available.
