7.2.4  Low Rejection Warning (Due to High Purity Feed Water) 
The ECM-100 may exhibit a low rejection warning condition when 
the factory default low rejection alarm setpoint of 88% is used with 
high purity feed water. The permeate conductivity may be 
acceptable, but the percent (%) rejection may read low enough to 
cause an alarm.
