23G-Series RO System
3024270 Rev G 56 14Oct13
WARNING:
Determination of microbial culturing and disinfection frequency is the
responsibility of the operating facility. Failure to conduct timely microbial
culturing and disinfection could pose a risk of serious injury or death to
hemodialysis patients.
1. Observe and record hardness level in the feedwater to the RO (for
systems with softener pretreatment).
NOTE:
Check the softener output for hardness at the beginning of each day and
at the end of each operational day to confirm adequate softener capacity.
The hardness level should be less than 1 grain per gallon (GPG).
2. Observe and record salt level in brine tank (for systems with
softener pretreatment).
3. Observe and record Total Chlorine (Chlorine/Chloramine)
concentrations in the feedwater of the RO. Follow instructions
included in each test kit.
WARNING:
Take corrective action or contact the equipment supplier if any pre-
treatment device fails to provide adequate treatment of feed water.
4. Allow water temperatures to stabilize before recording Mar Cor
Purification Daily log sheet data.
5. Observe and record the pre-filter inlet and post-filter outlet pressure
gauges on the Operation Log. The difference in the pressure values
will measure the condition of the pre-filter cartridge. When the
pressure differential (delta P) doubles above the clean delta P, the
cartridges need to be changed. Refer to Section 5.9 for pre-filter
cartridge replacement procedure. Change out frequency is at least
monthly.
6. Observe and record primary and final pressures on the Operation
Log.
7. Observe and record the concentrate (reject) and permeate
(product) flow rates on the Operation Log. Allow water
temperatures to stabilize before attempting to record results, to
prevent errors due to fluctuating temperatures.
