Setting the RO % Reject Alarm
The RO % Reject Alarm monitors RO membrane perform-
ance and can be set between 65% and 90% reject.
Factory default is 75%. To adjust the alarm:
1.
Press MENU. Scroll to RO Options and choose
Low Reject Alarm. Use the up and down arrows
to set the low alarm. Press OK to accept set-
tings.
The alarm will alert the user when the RO % reject falls
below the % reject alarm level by illuminating the SYS-
TEM ALARM LED. See details by pressing MENU and
choosing System Alarm. See the “Error Conditions” sec-
tion later in this manual to interpret the error.
Setting the Feedwater Chlorine Level
To ensure that the RO membrane(s) in the DIamond TII
are not damaged by free chlorine in the feedwater, the
system electronics tracks the amount of chlorine
processed by the carbon prefilter (D502115) and alerts
the user when the carbon capacity is exhausted. There
are three selectable levels of free chlorine content, the
factory default is the highest level. If you know the free
chlorine level of your feedwater supply, you can set this
level through the DIamond TII menu:
1.
Press MENU. Scroll to RO Options and choose
Chlorine Level. Use the up and down arrows to
set the appropriate chlorine level in ppm. Press
OK to accept settings.
If you do not know the free chlorine level of your feedwa-
ter, the setting should be left at the factory default highest
level to avoid damage to the RO membrane(s).
