NOTE:
If the product pressure or product flow is insufficient, a low dialysate flow alarm will occur on the dialysis machine. Small adjustments to the product pressure may be made with the pressure adjust knob located inside the RO module on the feed water line.
Read the percent rejection. It should display in the green region between 85- 95% rejection.
WARNING:
The product water must be shown to meet AAMI Standard Water Quality in the
%rejection range displayed on that particular water source (refer to Technote 103, AAMI Maximum Allowable Contaminant Level).
Read the total dissolved solids (TDS). It should read normal for the region. The alarm should be set to twice the initial installation TDS reading or the next higher setting.
WARNING:
The product water must be shown to meet AAMI Standard Water Quality in the TDS range displayed on that particular water source (refer to AAMI Maximum Allowable Contaminant Level).
NOTE:
Mg/L may be used interchangeably with parts per million (PPM).
NOTE:
An alarm light is located to the right of the mute button that will illuminate if the product water total dissolved solids displays less than 0.5 mg/L. This is a rare phenomenon that can occur if the source or feed water is already highly purified; otherwise, the system needs to be checked.
