Section 1.1 WARNINGS AND CAUTIONS

WARNINGS

• Read this manual in its entirety before operating the Blend Valve Assembly.

• Misuse, improper operation, and/or improper monitoring of this system could result in serious injury, death, or other serious reactions to the end users of the equipment. All applicable standards and procedures regarding this piece of equipment must be followed.

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 Blend Valve Assembly.




Section 1.2 THEORY OF OPERATION

The SWT Blend Valve Assembly is an automatic, mechanical device that blends cold and hot water to maintain a selected temperature for optimal performance of the reverse osmosis equipment in a water purification system. The cold water bypass diverts to cold water only for pre-treatment backwash cycles and when the temperature set point is exceeded. This saves energy by limiting hot water use.




Section 1.3 SYSTEM COMPONENTS

Leak Detector with Auto Shut Off: (Optional Feature)

The Leak Detector is used to monitor for leaks in the water treatment room and will automatically turn off the municipal boost system and close the inlet water valve when a leak is detected.

When this feature is added the leak detector is placed on the floor. It should be placed at the lowest level of the floor where water will naturally travel.

When liquid is detected the water inlet valve closes and the pump will power off. When the system is in “Auto” or “Manual” modes of operation, the system will power on if no leak is detected.

To clear leak detection, repair the leak and clean up water spill. Gently shake the sensor to remove water.

Depending on the state of the valve, the valve knob will point

to open or closed

Section 4.1 ROUTINE MAINTENANCE

Routine inspection of the system is recommended. Follow all facility procedures regarding regular inspection of equipment.

System should be inspected as follows:

1. Keep component clean by periodically wiping with a soft cloth.

2. Do not use harsh chemicals to clean the outside components of the system.

3. Do not use solvents on decals.

4. Inspect regularly for leaks and tighten fittings gently if needed.




Section 5.1 ________ TROUBLESHOOTING

The check valves in the blend valve are highly important factors in its proper operation. If chips, dirt or other foreign materials lodge on the seats and prevent the checks from fully seating, there may be a bypass of water into the opposing line, and the blend valve will not operate to its set delivery temperature. A bypass may be detected by feeling the supply line while the blend valve is not operating. If, for example, the cold line feels hot, the cold water check is not seating properly. It should be removed and the checks and its seat cleaned.

Section 5.1 ________ TROUBLESHOOTING

To adjust the temperature of the water, loosen the Temperature Adjustment Lock Nut and adjust the temperature as needed while water is flowing fully through the valve. When adjusted as needed tighten lock nut to lock temperature.

Water too cold – Rotate the Temperature Adjustment Nut Counter-Clockwise

Water too hot – Rotate the Temperature Adjustment Nut Clockwise
