Use and Care Guide

QUARTZ SLEEVE:

Installation of the Quartz Sleeve:

Always handle quartz sleeves carefully to prevent breaking or chipping. The quartz sleeves are to be clean and

free of fingerprints before installing.

Remove the compression nut. Install the quartz sleeve (domed end first) into the stainless steel housing, through

the threaded nipple. The quartz sleeve will go to the bottom of the chamber and through a quartz receiver locat-

ed within the bottom of the UV chamber. This will leave approximately 1/2" of the quartz sleeve exposed above

the SS nipple. (If you have more then this amount or it appears to have a slight tilt, the sleeve is NOT seated

properly. Remove the quartz sleeve and reposition for it to obtain the proper seal. Install the O-Ring down the

top of the nipple. Avoid riding the O-Ring on any threaded part of the nipple. Hand-tighten each compression

nut to form a compression seal around the quartz sleeve. Avoid overtightening the nuts, which may cause a

fracture on the end of the quartz sleeve. Under normal operation conditions, hand-tightening will provide a 100

psi seal. Do not use any devices to tighten end nuts. Repeat this procedure at the opposite end of the chamber.

After you have tightened the compression nut and all other plumbing connections, open the outlet valve. Slowly

open the inlet valve and flush out all remaining air. Then close the outlet valve and

slowly open the inlet valve fully. Check the unit for leaks. If you find a leak at the compression nut, tighten the

nut further. If the leak continues, drain the unit and inspect the quartz O-Ring and quartz sleeve for proper seal.

Once you complete checking the unit, reassemble O-Ring and tighten gland nut. Repressurize the unit and check

again.

REQUIREMENTS FOR CLEANING THE QUARTZ SLEEVE:

As water passes through the U.V., minerals, debris and other matter in the water may deposit onto the quartz

sleeve. After sufficient film has formed on the quartz sleeve, the ability of the ultraviolet

germicidal rays to pass though the quartz sleeve and into the water may be impaired. Therefore, it is necessary

to determine a cleaning schedule for the quartz sleeve. The frequency will depend on the

specific type of water conditions. If the water has been processed through deionization, reverse

osmosis, or is distilled, cleaning may be required only once per year. If untreated water is used, the cleaning

frequency will vary. A minimum of once yearly is standard recommendation for cleaning and lamp replacement.

Contact your local dealer for scheduling this service. Your specific situation will vary the frequency time accord-

ing to the water quality of the home or facility application.

QUARTZ SLEEVE CLEANING PROCEDURES:

To clean the quartz sleeve, turn off the water flow to the disinfection unit, turn power off, and disconnect the

electrical service to the lamp pins. Carefully remove the U.V. lamp. Loosen the compression nuts with O-Rings

and remove the quartz sleeve while draining the water from the chamber. The quartz sleeve may then be washed

with a mild soap and hot water solution and rinsed clean with hot water. Should this be insufficient to clean the

quartz sleeve, a mild acid may be used (i.e. vinegar). Be certain to follow all recommended safety and handling

procedures on the acid container. It is important to handle the quartz sleeve with care to prevent breakage. Make

certain that all finger prints are wiped clean before reinstalling (see installation of the quartz sleeve).

Replace the unit specific O-Rings

[P8-8-544(1), P12-8-544(1), P20-8-546(1)] every time a quartz sleeve is cleaned or replaced.
