• Misuse, improper operation, and/or improper monitoring of this equipment could result in serious injury, death, or other serious reactions to the end users of the equipment.

• A regular disinfection schedule for the water treatment components including the Ultrafiltration for High Purity Distribution System should be outlined by the Governing Body of the facility. If the system is opened, a complete disinfection must be completed before dialysis treatments can be initiated.

• The Ultrafiltration for High Purity Distribution system must never be used as a primary filtration device. The system is designed for final filtration only.

• All hemodialysis treatments must be discontinued prior to initiating disinfection of the Ultrafiltration for High Purity Distribution System.

• The Ultrafiltration for High Purity Distribution System contains items which contact the final product water to the end user. Do not modify or adjust any part of this system. All replacement parts must be obtained from Specialty Water Technologies.

CAUTIONS

• When used as a medical device, Federal law restricts this device to sale by or on the authority of a physician. Per CFR 801.109 (b)(1).

• It is the responsibility of the governing body of the facility to ensure that all applicable regulations regarding the installation and operation of this system are observed.

• Only authorized personnel can install, perform service, or perform maintenance to the Ultrafiltration for High Purity Distribution System.

• Ultrafilters are to be used only for post-treatment of reverse osmosis (RO) treated water and are not intended to provide primary purification.




Section 1.2 THEORY OF OPERATION

The SWT Ultrafiltration Rack for High Purity Distribution is designed for high purity water loop distribution primarily in the medical (dialysis) setting in conjunction with the SWT High Purity Digital Storage and Distribution System, K-A-UPT-X-D series, for the monitoring of the digital pressure gauges, conductivity meter and digital flow sensors. It is constructed of fiberglass membrane vessels with Teflon fittings and connections. The system is placed on the permeate water distribution loop. The Ultrafilter membranes remove particle and microbial contamination from the permeate water and are just one component in a complex system of water purification equipment for dialysis processes. The Membranes contained in the Ultrafiltration Rack will reject microbiological contamination as opposed to a dead-end cartridge filter that traps particles. By setting a reject flow, the contaminants are flushed from the membranes. The reject flow rate can be turned off during non-operational hours of the facility. The Ultrafiltration Membranes are tolerant to bleach and renalin / peraciden at a 1:100 dilution ratio. They are not compatible with high level disinfection with bleach or renalin / peraciden. The membranes will not tolerate heat or ozone disinfection. The SWT Ultrafiltration Rack features zero dead leg plumbing, high purity sample ports, 316 S.S. pressure gauges / sensors, output flow sensor, sampling cups, drains, and an adjustable reject with shut off valve.

3. Using the (4) 5/16” x 1½” lag screws with the 1/2” flat

washers provided in the hardware kit, secure the strut to the plywood on the wall. Secure at the ends of both strut pieces. When leveling, place the level on the strut, not the membrane housings.

4. Attach the top valve assembly by connecting and tightening the valve connection.

5. Use the sheetrock screws and white caps to secure plastic brackets to plywood in pre-drilled holes.

6. Connect green permeate tubes to top of membrane housings.

7. Make inflow and outflow connections as needed for existing loop.

8. Attach drain assembly centered under each sample port.

9. Plumb the drain to the nearest source as desired. May be plumbed to the right or left.

**Loop and UF Rack must be disinfected before initiation of hemodialysis treatments**




Section 4.1 OPERATION

INITIAL START-UP

1. On initial start-up or membrane replacement, divert the product water flow to drain (not to reservoir or distribution loop) for a minimum of 2 hours to rinse preservative from the membranes.

DAILY START-UP

1. Ensure the R.O. has been placed into the OPERATE mode.

2. Ensure storage tank is at least half full (not applicable to direct feed systems).

3. The inlet and outlet valves open, and the by-pass valve is in the closed position.

4. Open the reject shut-off valve.

5. Verify that the reject flow is 5% to 10% of product flow.

MONITORING PROCEDURES

1. The Ultrafilter system must be monitored on a daily schedule by a qualified technician using a checklist. An example checklist is provided in Appendix A of this manual and may be reproduced for use.

2. The filter gauges should be checked with water flowing when there is NO demand for purified water.

3. Monitoring Requirements:

Filter System Inlet Pressure

Filter System Outlet Pressure

By-pass Valve Normally Closed

Product Flow

Reject Flow

Bacteria/Endotoxins (check at least monthly; more often if necessary) must meet established standards.




Section 4.2 OPERATION

ADJUSTING PROCEDURES

1. The only adjustment to a 4x40 Ultrafilter System is the reject flow.

Locate the reject flow rate adjustment knob on the filter system.

Slowly turn the adjustment knob clockwise or counterclockwise as required to increase or decrease the reject flow rate to 5-10% of product flow.

2. Any other adjustments are to the loop delivery pump and/or the pressure by-pass on the loop return at the storage tank.

Section 4.3 DISINFECTION PROCEDURE

** See System Illustration for Clarification of Components **

This is a general guide for disinfection of the Specialty Water Technologies Ultrafiltration Rack. The user must follow all facility policies and guidelines regarding this component of the water treatment system.

*** Ensure there are no hemodialysis treatments in session

*** Do not expose UF membranes to bleach concentrations greater than 1:100 dilution of 5 - 5.25% Sodium Hypochlorite.

*** Do not use: ‘splash-less’ or gel bleach (creates foam), or scented bleach.

1:100 Disinfection: Membranes are not bypassed.

1. Turn Loop Pump off. 2. Fill storage tank to 90 gallons of RO water. 3. Add appropriate amount of disinfectant to tank to make a 1:100 concentration

solution. 4. Turn the loop pump on to circulate the disinfectant through the loop 5. Verify presence of disinfectant at loop return point 6. Circulate disinfectant through loop for amount of time stated in facility policies

and procedures. 7. Recommended dwell time of no greater than 30 minutes. Prolonged exposure

to bleach will shorten the life of the membranes. 8. During the circulation of disinfectant, open and close both sample ports, the

reject shut off and reject flow adjustment valves to flush with disinfectant. Very quickly, rotate the UF Bypass Valve (Red Handle) to the bypass position.

9. Then close the Membrane Product Valve (Blue Handle). Do not close the Membrane Product Valve with the loop pump running unless the UF Bypass valve is on “Bypass”

10. Open the Membrane Product Valve (Blue Valve). 11. Place the UF Bypass (Red Handle) valve to the “Service” position.

Rinsing Procedure:

1. Rinse the storage tank of disinfectant and ensure disinfectant tests negative at the loop return.

2. With the loop pump running, repeat steps 8-11 above. Rinse loop for the time frame designated in facility policies and procedures.

3. Check for absence of disinfectant at all points of use. 4. Thirty minutes later, check for absence of disinfectant at all points of use.

** Disinfectant must be thoroughly rinsed and tested negative **

** Due to possible rebound of disinfectant, it is recommended that another test for disinfectant is done prior to initiation of hemodialysis treatments **
