4400M RO Manual

4400M Digital RO System

NOTE Flow adjustment should be made slowly.

NOTE The flow rates in steps 10-12 must be verified and adjusted until the system has stabilized. A +25/ -15% variation in product flow rate can occur within the first three months of operation.

13. Allow the system to drain for two hours (four hours for dialysis application). Record and verify that the system parameters are within the desired limits.

14. Once the time has elapsed and the system parameters are met set the controller to the STOP mode. Close the product CIP valve and disconnect the flexible line. Fully open the product valve connected to the process (for example, tank).

15. Place the system back into the RUN mode.

NOTE Once the system is in operation, daily checks, in each shift, must be logged in the Table of System Monitoring parameters in APPENDIX

A9 . Flow and

pressure adjustments must be made to operate the system within parameters

specified in Section 3.5. Failure to operate the system within limits will void

the product warranty.

16. A complete sanitization using MINNCARE

®

disinfectant (refer to section 4.4) must be performed

to assure the water meets or exceeds the ISO13959, ISO 11663 and ISO 26722 requirements.

17. After the sanitization is performed, take the necessary water samples and have them analyzed

by an accredited lab. Refer to APPENDIX A6 for Water Sampling Procedures.

NOTE

NOTE

The water cannot be used for dialysis until the water quality is verified and signed off by the physician.

Upon successful start-up, the Site Acceptance Test (SAT) must be executed and

approved by the customer. Refer to the SAT document in APPENDIX A10 for

details of the quality requirements.

NOTE After initial installation and subsequent use, if any component of the water treatment system is changed or replaced, the user should conduct appropriate tests to ensure that the revised system meets the initial design criteria.

2.5.5 Checking the RO Pump Rotation

The procedure below provides the necessary steps to check the circulation pump rotation. The procedure is used on pumps that have been supplied with 3-phase feed voltage input requirements.

1. Make sure the controller is in the STOP mode.

2. Viewed from the top of the motor, the pump must be rotating counter-clockwise.

3. Cycle the controller from the STOP to the RUN mode and allow the pump to start. Verify the rotation. Cycle the pump a few times to make sure the rotation is correct.
