USD-RBE Series units only

The quartz sleeves for this unit utilize a design that is open on one end and

closed on the other end. The closed end of the tube is inserted into the threaded

nipple and then through the baffle system in the chamber. Within the baffle,

Teflon bushings provide additional support to the quartz sleeves.

OCEDURES

For first time unit installations, follow these quartz sleeve

installation procedures:

1. Turn off all power to the unit.

2. Wear clean cotton gloves to prevent contamination of the quartz sleeves.

3. Carefully remove each quartz sleeve from the factory packaging.

Handle these with care as they are fragile.

4. Visually inspect all quartz sleeves for cracks or other damage. Do not

install damaged quartz sleeves.

5. Remove the socket covers on the ends of the treatment chamber.

6. Remove all compression nuts and any packaging material from the end

plate (if installed).

7. Place the closed end of the quartz sleeve into the threaded nipple and

slowly push the sleeve into the chamber. Some resistance may be felt

from the Teflon bushing.

8. Install the compression nut and o-ring by placing the o-ring into the

internal relief of the compression nut below the threaded area.

The o-ring should fit into the compression nut.

9. Place the compression nut and o-ring onto the end of the quartz sleeve until the

end of the quartz sleeve touches the end of the compression nut and hand

tighten until snug. Deionized water may be used as a lubricant.

10. Tighten the compression nut approximately 1/2 turn after the threaded

nipple and o-ring make contact.

11. Repeat this procedure for all quartz sleeves.

12. Slowly pressurize the system and fill the chamber with water to check for leaks.

13. When applicable, bleed the air from the UV treatment chamber by opening

the plug on top of the chamber. Replace with a suitable valve.

14. If there are leaks in any compression nut assembly, depressurize the system

and use the compression nut tool to slightly tighten the leaking compres-

sion nut assembly.

15. Retest until a leak-free installation is verified.

16. You are now ready to install the UV lamps.

Over tightening can break the

quartz sleeves or create leaks.
