Digital Flush Timer
The Digital Flush Timer is an important component of the Reverse
Osmosis Machine, located inside the control box. The flush timer
is a 24-hour adjustable 24 volt digital mechanism that controls the
frequency and duration of the Flush Cycle.
The Flush timer serves two purposes: It is used to set the time of
day, and the frequency and duration of the Flush Cycle(s).
The digital flush timer is equipped with a battery back-up, so loss
of power to the RO will not affect the timer operation. However, the
actual life of the battery is not known so the timer should be checked
monthly for correct time of day setting.
The Flush Timer was preset by the system installers on the day of
the installation. Once the Frequency and the Length of the Flush
Cycle have been set, that setting will remain until manually changed.
See the section on System Maintenance for details on battery replacement and adjustments.
Temperature Controller
The Temperature Controller inside the control box monitors the
pretreated feed water temperature at the RO. A high-temperature
set-point is set via this controller and in the event the water temperature
reaches this set-point a high-temperature alarm light will
illuminate, an audible alarm sound, and the RO will shut-off.
* See Technical Service Bulletin TSB2014001 in Appendix B if
replacing.
Tank-Stby-Direct Switch
The Tank-Stby-Direct switch is a three position toggle switch which
determines if the RO will run in conjunction with the signals from the
floats in a reservoir or will run continuously.
Switch Setting:
DIRECT
RO will run continuously, and bypass the float
switches in the reservoir. For direct feed ROs
only.
STBY
RO will not run
TANK
RO will recognize float signals from the reservoir.
There is a fuse above the switch, for the 24 vac power to the main
control board and water quality monitor.
NOTE: On devices manufactured prior to August 2007, and from August
2010 to present this switch is located inside the control box. On devices
manufactured from August 2007 through July 2010, this switch is on the
outside of the control box
