5.0 MACHINE OPERATION AND MAINTENANCE
Proper maintenance of the 23G RO system in accordance with this manual and
good medical practices is essential when the system is used in a medical
application for water purification for use in hemodialysis. FAILURE TO FOLLOW
THE REQUIREMENTS SET FORTH IN THIS SECTION AND GOOD MEDICAL
PRACTICES COULD POSE A RISK OF SERIOUS INJURY OR DEATH TO
HEMODIALYSIS PATIENTS.
Mar Cor Purification 23G RO systems have been designed to operate with a
minimum of operator attention. Like all mechanical systems they will operate
longer and with less trouble when routine maintenance is performed regularly.
Maintenance on an Mar Cor Purification reverse osmosis system is typically
limited to completing performance logs, cleaning, flushing, sanitizing, changing
pre-filters, regular maintenance, and replacement of damaged or failed parts.
The maintenance procedures are as follows: (specific instructions follow the
maintenance schedule).
There are seven preventative maintenance procedures which must be performed
on a regular basis:
1. Maintain the pH buffer system (if applicable).
2. Changing the pre-filter cartridges.
3. Flushing the machine.
4. Verifying product water quality.
5. Cleaning the machine with approved Mar Cor Purification cleaners.
6. Sanitizing the machine with approved Mar Cor Purification sanitizing
agents.
7. Cleaning and checking calibration of pH and conductivity probes.
5.1 Daily Requirements
NOTE:
Allow water temperature to stabilize before attempting to record results.
This prevents errors due to fluctuating temperatures.
Operating performance data should be recorded daily and kept on file and
submitted to your equipment supplier or Mar Cor Purification. Daily log
sheets are included in the instruction manual package and are useful for
recording performance data. In addition, data automatically stored by the
ECM-100 can be downloaded to a printer or computer to facilitate and
simplify record keeping. Copies of Mar Cor Purification Daily Log Sheets
will be required by Mar Cor Purification if a warranty question arises.
